BMW 3-Series Coupe, 2011

BMW 3-Series Coupe, 2011

 


BMW has announced substantial enhancements to the 2011 BMW 3-Series Coupe and Convertible, including outstanding style updates for 328i and 335i models and a new engine for 335i models. The 2011 BMW 3-Series Coupe and Convertible models will go on sale in Spring 2010, and pricing will be announced closer to the on-sale date.

Fundamentally unchanged are each car's essential attributes of rear-wheel drive (xDrive is available on the Coupe), near-perfect 50-50 weight distribution, remarkably precise steering, and skillfully engineered suspension…all of which conspire to produce the uniquely satisfying driving experience that is quintessentially BMW.

All-new is the engine for the 335i model. Internally designated the "N55," this turbocharged, all-aluminum engine features essentially the same "short block" and 3.0-liter displacement of its predecessor, but benefits from five additional years worth of development and refinement. The result is an engine that is more responsive, more fuel efficient, and cleaner-running than its outstanding predecessor, but preserves the previous engine's output and soul: 300 horsepower and 300 lb-ft of torque, and a 7,000 rpm redline. The 6-speed manual gearbox - beloved by North American enthusiast drivers - remains standard, and the well-known 6-speed Steptronic automatic is optional, now featuring "pull-style" shift paddles on the multifunction steering wheel.

Design. Reflecting the legendary distinction of BMW Coupes and Convertibles

The profile of the BMW 3-Series Coupe and Convertible is instantly recognizable at first glance. Beyond the basic shape of the car and its classic lines, the new design of the headlights, the enhanced depth and detail of the taillights, the interior, and even the exterior mirrors were specifically created for the Coupe and Convertible. These unique design elements reflect the sporty character of the car. The driver who chooses a two-door vehicle desires a car with dynamic looks as well as driving performance. With this in mind, BMW engineers and designers set out to create a unique, unmistakable blend of design features and most importantly, driving pleasure.

It all begins with proportions. The new, long hood powerfully symbolizes BMW's loyalty to the inherently balanced inline-6 engine. The long wheelbase, short overhangs, the passenger compartment set aft and the low, sleek roofline which seamlessly slopes into the trunk are all characteristics of the BMW Coupe and BMW retractable hardtop Convertible.

In addition to the classic proportions, three design lines—the shoulder, character and lower sill lines— enhance the sleek appearance. Both the shoulder line and character line stretch uninterrupted to the back of the car, allowing one's eye to move quickly and smoothly from front to rear along the entire length of the car. The sill line of the lower edge of the door flows into the front and rear air dams, reinforcing the dynamic nature of newest BMW 3-Series Coupe and Convertible.

The combination of lines flowing into one another elegantly emphasizes the vehicles' performance potential. While the shoulder line rises slightly but consistently from front to rear, the character line flows in a long, stretched arch all the way from the front fender to the new taillights. As the sill line, by contrast, moves up slightly to the rear in a slow and gentle curve, the distance between the character and sill lines becomes smaller near the rear wheel arches. The fender flare around each rear wheel also serves to give the character line extra tension in both an upward and outward direction.

Attractive new innovations at the front, side, and rear - integrated precisely into the overall look of the car- give greater emphasis to the sportiness of both models. At the same time, these modifications slightly extend the overhangs front and rear (now 1.14" and 0.12" longer, respectively), which adds a sleeker and even more athletic appearance.

The new, widened kidney grille, a signature feature of every BMW, suits the broad new hood and stands out from the surfaces around it. Interaction with the three-dimensional kidney frame creates a look of power and unique style. The frame around the kidney grille now features a chrome band precisely twisted within itself.

The BMW 3-Series Coupe and Convertible come standard in the U.S. with Xenon Adaptive Headlights, accented by BMW's signature corona light rings. At the top, the new headlights merge into a trim bar cutting off the light beam to create that concentrated, focused look typical of a genuine BMW. The corona rings, now powered by super-bright LED light sources, can serve as daytime running lights (if that feature is activated), and also as evening city lights, making the Coupe and Convertible instantly recognizable as a BMW, day or night. The upper edge of each headlight fixture is also illuminated by an LED light source.

The new design of the taillights is unique to the BMW 3-Series Coupe and Convertible. The rear light cluster feature two-piece L-shapes and are further accentuated by a new color scheme. With two rows of light tubes that illuminate simultaneously, they create a night design with depth and dimension. Integrated flush into the body of the car, the lights are split into two sections and extend up the trunk lid, blending with the character lines from the side profile. Horizontal LED tube taillights give the car an unmistakable look at night. The horizontal flowing lines accentuate the wide track and low stance of the Coupe and Convertible.

An additional horizontal contour line has been added to the rear air dam to further accentuate the width of the Coupe and Convertible. It creates light-and-shade effects to give the entire rear end a flatter and smoother appearance.

The exterior mirrors also receive a new design, adding further innovation to the unique looks of the BMW 3-Series Coupe and Convertible. They blend harmoniously into the side view and silhouette of each new model.

Interior: a truly stylish ambiance
The emphasis on individual style, dynamic performance and exclusivity continues within the interior. Here again, the focus is on the driving experience, as announced by the standard leather multifunction steering wheel. Horizontal lines dominate the surfaces on and around the instrument panel which blend with the lines of the center console door panels to give the interior a light but dynamic feel. In true BMW fashion, all operational and informational elements essential to driving are grouped on and around the steering wheel. Climate controls, as well as those for the audio and navigation systems, are within easy reach of the front passenger.

Because the Coupe and Convertible are four-passenger cars, the rear seat passengers are treated to a center console between their individual rear seats which includes individual storage boxes, additional air outlet vents, and footwell lights.

The BMW 3-Series Coupe and Convertible come standard with Dark Burl Walnut wood trim. As a choice, Bamboo Anthracite wood, Light Burl Walnut wood, and Aluminum trim are optional. Like the standard Dark Burl Walnut, these materials appear on the dash, front and rear consoles, doors and rear side panels.

The standard leatherette upholstery is available in Black and Creme Beige. For the optional leather upholstery, luxurious Dakota leather can be chosen. Here too, the buyer may choose Creme Beige, Oyster, Coral Red, Saddle Brown, Gray, or Black. Upholstery leather appears on the seat facings, door inserts and door handle surrounds; other leather-trimmed items include the gear shift boot, handbrake grip and steering wheel.

In other items of trim that don't change with upholstery or trim options, the interior door handles, gearshift surround trim, steering wheel spokes, instrument dial and engine Start/Stop button surrounds, dash air-outlet adjusting tabs and the optional iDrive controller are in pearl-gray galvanic material.

An elegant ambiance is further created in the interior by special lighting and switches with a premium look and feel. Ambiance lighting, streaming down from under the ledge on the door and side panels, and running from the A pillar all the way to the rear passenger area, creates a particularly warm, indirect lighting effect.

Through its design and configuration, the cabin emphasizes the sporting and driver-oriented character of the BMW 3-Series Coupe and Convertible. Taking a seat behind the steering wheel, the driver's eyes will immediately focus on the instrument cluster.

Bentley Mulsanne, 2011

Bentley Mulsanne, 2011

 
  

 


While paying homage to past Bentley greats, the brief for the new Bentley Mulsanne design and engineering teams was to create a Bentley that represents the pinnacle of British luxury motoring.
The new Bentley Mulsanne, designed and engineered at Crewe from the ground-up, reaffirms the marque's intent to create a new flagship Bentley with refined performance, unparalleled levels of interior luxury and coach building skills to the fore.

The return of the Mulsanne name underlines Bentley's sporting heritage and passion for power and speed. Nothing reflects that prowess better than the legendary Le Mans 24 Hours, a race that Bentley has won on six occasions, where its powerful and reliable race cars thundered down the long Le Mans straight into the famous Mulsanne corner, from which the new model takes its name.

A pure expression of Bentley design
The design of the new Bentley Mulsanne is a unique fusion of sportiness, coachbuilt elegance and solidity. Echoing the Bentley S-Type of the 1950s, the Mulsanne features a bold frontal design dominated by the traditional Bentley matrix grille and highly prominent, classic round inner headlamps with chrome surrounds, flanked by two, smaller outboard lamp clusters, all featuring the latest in lighting technology. The iconic 'Flying B' retractable radiator mascot is available as an option.

The long bonnet, short front overhang and long rear overhang help to convey a sense of power and movement, reinforced by muscular haunches and sharply sculptured lines which flow gracefully from the front wings to the rear. Uniquely designed 20-inch wheels (and optional 21-inch) reinforce the Bentley Mulsanne's powerful, sporting stance.

Design Director Dirk van Braeckel explains the inspiration behind the Bentley Mulsanne's distinctive appearance: "The opportunity to design a new flagship Bentley is something afforded to very few designers. The team set out to create a sculpted form that blended classic Bentley heritage cues with modern lines that allow the marque to stride confidently into the 21st century."

The body is produced in a new manufacturing facility at Bentley's headquarters in Crewe where traditional metalworking skills, developed over six decades, are still used extensively during the nine-week build process. It is the very opposite of volume-production car-building… but the very epitome of Bentley.

The rear screen, for example is fully enveloped by the coachwork. This provides a flowing, flawless line to the rear of the car, complementing the exquisitely formed D-pillars - whose complex curves can only be created by skilled coach-builders. All spot welds are performed by hand during the Bentley Mulsanne's construction and all panel joints are hand-brazed. These further enhance that 'hewn from solid' appearance and result in an extremely stiff body.

The complex form of the aluminium front wings, impossible to achieve with normal pressing techniques, is created using superforming, a technology usually reserved for the aerospace industry. This also makes the wings both lighter, stiffer and provides superb surface definition. Other lightweight materials, such as the composite bootlid, are used to remove mass wherever possible without compromising quality.

New construction techniques meant the designers could also incorporate details such as the 'floating' elliptical LED tail lights, which uniquely echo the shape of the exhaust tailpipes.

To accentuate the beauty of the bodywork, the Bentley Mulsanne features 'brightware' exclusively in polished stainless steel, including sill treadplates and matrix grilles. Bentley is the only manufacturer in the world to do this. The stainless steel door handles also incorporate the traditional Bentley 'knurling' to their inboard surface for enhanced grip, reflecting the company's typical attention to detail.

The sporting character of the Bentley Mulsanne is reinforced by front wing vents and large diameter tailpipe finishers.

Sumptuous interior meets advanced technology
The latest in-car technologies are discreetly placed within the Bentley Mulsanne's sumptuous interior. A multimedia system with 40 GB hard disc drives satellite navigation, audio/video, personal data, telephone and Bluetooth® connectivity. The upper dashboard houses an 8-inch multimedia screen, positioned unobtrusively behind an electrically operated veneered door, while below sits a stylish, leather-lined MP3-player stowage drawer.

A state-of-the-art 14-speaker audio system with Digital Signal Processing (DSP) and 6-CD autochanger is provided as standard while the Naim for Bentley premium audio system may be specified as an option. This forging of two British luxury brands provides customers with the world's most powerful 2200 Watt in-car amplifier, eight dedicated DSP modes and 20 custom-made speakers, delivering an unparalleled sound quality.

A personalised keyless entry system allows multiple pre-programmed configurations and automatically sets radio stations, phone book, seat (including ventilation and massage modes, both front and rear), steering column and seatbelt settings and even the electrically operated rear-seat blinds for side and rear windows. As a world-first, the keyless system operates with the stainless steel door handles which incorporate touch points to initiate communication with the key for verification and entry. The Bentley Mulsanne also features keyless start, having a stop/start button on the centre console.

The Bentley interior design team has continued to develop and evolve the luxurious interiors for which their cars are renowned, based on a large-scale, research programme to identify the classic signature features that have defined Bentleys from the 1920s to the present day.

Armed with this invaluable resource, the Bentley Mulsanne's design team set itself highly challenging targets for key interior characteristics such as material design, smell, colour harmony and handcrafting. Similar targets were set for the operational refinement and robustness of all control mechanisms. The result is a hand crafted interior that fully reflects traditional Bentley values, executed to the highest possible standards, where customers may tailor their cars to their individual specification.

As Head of Interior Design, Robin Page says: "Over 170 hours - almost half the entire build process - goes into crafting the interior of the new Bentley Mulsanne. At Crewe, Bentley's way of working is the opposite of mass production - we start where others stop."

The use of wood and leather hides has increased significantly to create an even more refined and luxurious cabin. While classic design features such as bulls-eye air vents (now also fitted in the rear compartment), high-quality mirror-matched wood veneers, leather hides and hand-finished stainless steel are retained, they are mixed with new touches such as beautiful glass switches.

The entire cabin is encased within a 'ring of wood' waistrail with an unbroken panel of wood gracing the Bentley Mulsanne's dashboard. Inverted dial needles within the instrument cluster are evocative of early Bentleys while the entire dashboard and console design is a subtle reminder of the Bentley wings motif.

The Bentley powertrain engineers were set three objectives for the Bentley Mulsanne:
   1. To produce the effortless torque from extremely low revs that customers expect of a grand Bentley
   2. To maintain the highest levels of refinement
   3. To satisfy strict current and future environmental standards through improved engine efficiency

VW Amarok, 2011

VW Amarok, 2011

 
 
 
The Volkswagen Amarok.
Production of the Volkswagen Amarok is about to start at the Volkswagen factory in Buenos Aires.
The Volkswagen Amarok has a generous payload capacity of up to 1.15 tonnes and maximum towing limit of 2.8 tonnes. Its 2.52 m² cargo area has the largest dimensions in its class at 1,555 mm long and 1,620 mm wide, plus a best in class width between the wheelarches of 1,222 mm, which means that for the first time on a mid-size pick-up, it is possible to load Euro pallets sideways, saving on space.

The official photos show the Volkswagen Amarok reflects the latest Volkswagen design DNA with frontal styling in line with the latest Transporter and Golf. It is 5.25 m long with a ladder frame chassis and will be offered with a choice of rear-wheel drive and switchable or permanent 4MOTION all-wheel drive.
For maximum convenience, the switchable all-wheel drive is engaged by the push of a button, and also has low off-road gearing.

Designed to tackle the toughest off-road terrain, the VW Amarok is offered with an electronic differential lock (EDL) and Off-Road ABS to significantly shorten braking distances in off-road conditions or gravel roads. At speeds of under 20 mph it also activates Hill Descent Assist to control hill descents by using selective braking interventions. Furthermore, the ESP Plus system includes Hill Hold Assist, which prevents the vehicle from rolling back by holding it in place on inclines until the driver presses the accelerator pedal.

Under the bonnet there will be a choice of two 2.0-litre fuel-efficient, Euro5 compliant, common rail TDI engines producing 163 PS, with torque of 400 Nm at a low 1,500 rpm, or 122 PS with maximum torque of 340 Nm from 2,000 rpm.

Both engines have a 6-speed manual transmission and will have impressive fuel economy with low emissions to make the Volkswagen Amarok the first all-wheel drive pick-up in this class offering CO2 emissions of less than 200 g/km.
Like the new Transporter and Caravelle, the Volkswagen Amarok has a gearchange indicator to help drivers achieve the best fuel economy, which with an 80-litre fuel tank should offer a range of over 600 miles.

The large and ergonomically designed interior is the largest in its class and in many ways resembles that of a Volkswagen passenger car. Easy entry, lots of headroom and ample legroom for passengers on the rear bench seat make the Volkswagen Amarok a fully-fledged five-seater. If only two people are travelling, interior storage space can be increased by folding the rear seat.

VW Touareg, 2011

VW Touareg, 2011

 


Volkswagen is unveiling the completely redeveloped Volkswagen Touareg as a world premiere. It is the most technically innovative "VW" since the brand has been in existence. This Volkswagen Touareg is reinterpreting the fascinating multipurpose SUV idea in a contemporary way - thanks to a range of engines that are nearly 20 percent more fuel efficient and a large variety of new assistance and safety systems. The VW Touareg will also be the first and only off-roader in Europe by a German car maker to be available in a hybrid version too. It sets standards among fully off-road capable SUVs with petrol engines that have a fuel consumption value of just 8.2 litres fuel per 100 kilometres. The Volkswagen Touareg Hybrid can be driven up to 50 km/h in purely electric mode - emissions-free. Among the diesel engines, the Volkswagen Touareg V6 TDI with 7.4 litre combined fuel consumption now posts the best value in the segment of genuine SUVs. Both versions, the VW Touareg Hybrid and V6 TDI, are the most fuel efficient petrol and diesel SUVs ever built in Europe in this large vehicle class.

New era SUV - lighter, more aerodynamic and fuel efficient
As has already been accomplished on the globally successful, smaller Tiguan, Volkswagen is systematically striving for sustainability on the new Touareg too. The first precondition was met: The SUV was lightened by 208 kilograms in the base version! A quantum leap. Yet, the body has five percent greater torsional rigidity, which makes it the leader in its competitive class. A second precondition was met as well: Designers attained a significantly improved Cd value. Along with aerodynamic refinement efforts, another factor at work here is that this Volkswagen Touareg is built lower to the ground than the previous model. Together with front end styling based on the new Volkswagen design DNA, this results in a smaller frontal area. The third precondition: All engines, now offered with a standard 8-speed automatic transmission - a first in this market segment - demonstrate significant fuel economy advantages over the previous model; in some cases the advantage is far greater than two litres per 100 kilometres.

SUV for all trails - All-wheel drive in two versions
Also modified in pursuit of reduced fuel consumption was the standard all-wheel drive. In the base version ("4Motion"), all new generation VW Touaregs have all-wheel drive with Torsen limited-slip differential (4MOTION; climbing ability: 31 degrees). Like the Tiguan Track & Field, the VW Touareg also has an "Off-road driving programme", which - at the press of a button - tunes the ABS, EDS and ASR for off-road duty, activates Hill Descent Assist and adjusts the automatic gearshift points.

Instead of a Torsen differential, the V6 TDI can be ordered with an optional "Terrain Tech Packet" that has an even more rugged transfer case designed for off-road duty. It includes reduction gearing and centre and rear differentials, each with up to 100 percent locking (4XMOTION; climbing ability: 45 degrees). Similar to the first generation Volkswagen Touareg, this version also has a rotary switch the driver now uses to adapt the car to specific duty conditions over five levels: 1. "On-Road"; 2. "Off-Road" (like "Off-road driving programme" plus automatic control of the mechanical locks); 3. Low (like "Off-road" plus activation of reduced gearing, higher shift points, no automatic upshift in manual mode); 4. Addition of centre differential lock; 5. Addition of rear differential lock. Equipped like this, the Volkswagen Touareg can conquer any terrain on Earth.

SUV for everyday driving - more space, more innovations
Volkswagen has not only made the new VW Touareg lighter, more fuel efficient and an agile performer; it has also made it into an even more versatile, all-round vehicle. The new interior was made more functional, the seats more comfortable and leg room in the rear is larger. Now the rear bench seat has 160 millimetres in longitudinal adjustment, and the backrest angle can be adjusted. Electrically unlatched at the press of a button as an option, it folds down in seconds and frees up 1,642 litres of cargo space. Already standard equipment in the base version is a radio-CD and info system, which is intuitively controlled over a 6.5-inch touch-screen.

Volkswagen Touareg - the best of two worlds
About 500,000 car drivers chose to buy the first generation of the SUV. It is a luxury sport utility vehicle that offers a high level of comfort, sporty driving properties, avant-garde styling, excellent quality and unlimited expedition capabilities - essentially the best of the passenger car and off-road worlds unified in one concept. This is now being followed up by the new VW Touareg - a high-end and versatile all-round vehicle that brings these two worlds together even more perfectly. The Volkswagen Touareg will already be available at dealers in April 2010.

Aston Martin Vantage GT4, 2009

Aston Martin Vantage GT4, 2009

 


Aston Martin Racing has released the 2009 specification Aston Martin Vantage GT4 based on Aston Martin's new 4.7 litre Aston Martin V8 Vantage. The new Vantage GT4 builds on the success of its predecessor, the 4.3 litre Vantage N24.

The Aston Martin Vantage GT4 has been under development for six months and was unveiled in Dubai this week by Aston Martin chairman, David Richards, and tested extensively at the Dubai Autodrome.

The car is an evolution of the N24 with the larger capacity engine being more responsive with increased torque throughout the rev range. The suspension has been retuned to enhance the handling, including modified front uprights to give increased camber. The 2009 Aston Martin Vantage GT4 also has larger front brake discs with revised cooling.

The Aston Martin Vantage GT4 is built to FIA GT4 regulations and is eligible to compete in the following series: FIA GT4 European Cup; British GT4 Championship; Britcar Endurance Series; German GT4 Championship; Dutch Supercar Challenge; Dutch GT4 Championship; VLN Endurance Championship at the Nurburgring; Australian Endurance Championship; the American SCCA Championship; and the Aston Martin Owners Club Race Series.

The Aston Martin Vantage GT4 is based on the latest 4.7 litre V8 Vantage and is hand built by Aston Martin Racing. The 4.7 litre eight cylinder engine has an engine management system recalibrated for race use. It also has a free flow exhaust system and air filters, and the standard V8 dry sump lubrication system is retained, helping to prevent oil surge during cornering.

The Aston Martin Vantage GT4 can be supplied with either a six speed manual, or a Sportshift transmission with paddle controls. Both versions have a Valeo twin-plate cerametallic racing clutch and lightweight flywheel to complete the powertrain specification.

At 1,330 kg the Aston Martin Vantage GT4 is 300 kg lighter than the standard car. This has been achieved through a range of weight reduction measures. The interior trim is removed with the exception of the facia moulding, which is re-trimmed in Alcantara, and the console and door casings are replaced by new lightweight mouldings.

The chassis has been fitted with a high-strength steel rollcage and Recaro competition seats. A suede-trimmed steering wheel with a quick release mechanism is also fitted as standard. The Vantage GT4's safety features are completed with a Sabelt sixpoint safety harness with a push-button release and Lifeline Zero 360 gas extinguisher system.

The V8 Vantage road car's suspension has required only minor adjustments for optimal track performance. These include larger diameter front and rear anti-roll bars and adjustable ride height aluminium dampers, as well as single rate, flat ground springs with separate helper springs. The front subframe is modified for extra camber and castor. Cast magnesium front and rear wheels are standard fit with high performance Yokohama A048-R tyres. The brakes are uprated with Pagid RS 29 race pads.

As further endorsement of the standard V8 Vantage underframe, the active safety systems are directly carried over to the Aston Martin Vantage GT4, including: dynamic stability control, traction control, ABS and electronic brakeforce distribution, providing reassurance and enhanced control in slippery conditions.

Aston Martin V8 Vantage Roadster, 2009

Aston Martin V8 Vantage Roadster, 2009

 


The Aston Martin V8 Vantage - originally launched to widespread critical acclaim at the Geneva Motor Show in 2005 - is to receive significant technical enhancements, reaffirming the car's position as one of the world's most desirable and exhilarating sports cars.

While the universally distinctive and award-winning shape of the Aston Martin V8 Vantage is retained, the car benefits from a number of technical changes which include significantly up-rated engine performance from a new 4.7 litre power unit in both Coupe and Roadster variants. Other changes include revised dynamics to take full advantage of increased power and torque availability, improved Sportshift™ transmission software and a new sports suspension option.

The 4.7 litre V8 engine has a power output of 420bhp (an 11% increase on the previous 4.3 litre unit) and delivers peak torque of 470Nm (15% increase), providing the Aston Martin V8 Vantage with new reserves of mid-range performance, an improved 0-60mph time of 4.7 seconds and top speed of 180mph (288kph). Combined European fuel economy and CO2 emissions are also improved by 13% (Sportshift™).

Inside, the changes include a new centre console and revised switchgear and the introduction of an ECU replacing the previous V8 Vantage key. Externally, the acclaimed Aston Martin V8 Vantage design appearance is enhanced with a range of new standard and optional 19'' alloy wheels.

Engine
Improvements in performance have been achieved through a number of carefully developed changes to Aston Martin's acclaimed V8 engine.
The cylinder bore and stroke has been increased from 89mm to 91mm and 86mm to 91mm respectively, giving a total displacement of 4735cc.

The increase in cylinder bore is facilitated by a move to cylinder liners that are pressed into the pre-machined aluminium alloy block, allowing a thinner liner than was possible with the cast-in design of the 4.3 litre engine.

The new forged steel crankshaft provides the 91mm stroke and incorporates new holes in the counter weights for reduced rotating mass and improved inter-bay breathing. New forged steel con-rods and cast aluminium pistons complete the capacity-related changes.

Other key changes include efficiency improvements to the dry sump lubrication system, including a new sump casting with oil pick-up points moved from the front and rear to the sides of the sump. The cylinder heads are modified with a new intake port and an inlet valve size increase from 34.9mm to 35.9mm. The intake manifold has been modified to match the new port to optimise air flow.

Transmission
The Aston Martin V8 Vantage transmissions have also undergone changes to improve performance and to handle the increased levels of power and torque. Both the standard manual stick-shift gearbox and the optional Sportshift™ transmission benefit from a modified clutch and flywheel, reducing clutch pedal efforts and delivering a 0.5kg weight saving, reducing the rotating masses within the powertrain, and hence increasing engine responsiveness.

Suspension
A series of improvements are introduced to the Aston Martin V8 Vantage chassis and suspension setup to deliver improved body control and low speed ride quality; enabling the driver to take full advantage of the increased performance potential.

A number of the improved components originally introduced on the Aston Martin V8 Vantage Roadster are now carried over to the Coupe, including revised upper damper mountings and bump stops. Additionally, the front spring rates are stiffened by 11% at the front and 5% at the rear.

Steering geometry is also modified to improve steering feel, while the front lower suspension arm compliance bushes are stiffened by 22% to provide enhanced steering response and handling.
The Aston Martin V8 Vantage also now benefits from Bilstein dampers as standard; these low-friction dampers provide improved levels of dynamic capabilities and further improve ride quality.

Design & Optional Equipment
Also introduced as an option for both Coupe and Roadster variants is a new Sports Pack which comprises forged lightweight alloy wheels aiding a lower unsprung mass, re-tuned Bilstein dampers with improved dynamic response, up-rated springs and a revised rear anti-roll bar (Coupe only). The Sports Pack is intended to offer greater agility, high speed body control and precision feel for the most enthusiastic of drivers.

Although the award-winning exterior design of the Aston Martin V8 Vantage remains largely unchanged, a new 20-spoke 19'' alloy wheel is introduced as standard, with either diamond turned silver or graphite finishes available as options, affording customers maximum choice. Alternatively, as part of the Sports Pack option, a 5-spoke lightweight aluminium wheel will be provided.

In the cabin, a new centre console constructed from die cast zinc alloy with a graphite silver finish is introduced along with a new ECU - first seen on the Aston Martin DBS in 2007. The ECU - constructed from glass, polished stainless steel and polycarbonate - replaces the key used previously for the Aston Martin V8 Vantage. The revised car also includes a new Hard Disk Drive (HDD) Navigation System offering faster route processing, additional features and improved graphics. Full ipod/MP3 integration is retained as standard equipment.

Performance
    * Max speed: 180mph (290 km/h)
    * Acceleration: 0-60mph 4.7 seconds
    * 0-100km/h (62mph) 4.8 seconds
    * Max power: 313kW (420bhp) @ 7000 rpm
    * Max torque: 470 Nm (346 lb.ft) @ 5750 rpm

Land Rover Freelander 2, 2011

Land Rover Freelander 2, 2011


 
 

The 2011 Land Rover Freelander 2 model range, on sale in the UK from the end of September 2010, benefits from a new 2.2-litre diesel engine available with either 150PS or 190PS outputs, a new look exterior plus interior alterations including new instrument dials and a new Premium Pack option.

Land Rover's new turbo diesel engine is available in the 4WD TD4 150PS model featuring a manual transmission and intelligent Stop/Start technology as standard (an automatic gearbox without Stop/Start is available as a cost option), or the new SD4 model delivering 190PS (available in automatic transmission only).

This new engine is quieter, more efficient and both derivatives have 20Nm more torque than the outgoing engine. This means the 2011 Freelander 2 offers improved engine response and more mid-range strength for towing. CO2 emissions have been significantly reduced to 165g/km and 185g/km respectively with corresponding fuel economy benefits.

However, despite reductions in consumption and emissions, there has been no compromise in performance. The flagship 190PS Land Rover Freelander SD4 accelerates from rest to 60mph in 8.7 seconds with an increased top speed of 118mph. The Land Rover Freelander 150PS TD4 manual and automatic versions match the performance of their predecessors.

As well as being upgraded from EU4 to EU5, both versions have a new variable geometry turbocharger and have been extensively re-calibrated to deliver new levels of power, meet emissions regulations and reduce CO2 emissions. They are fitted with a catalysed diesel particulate filter as standard and are now compatible with 10 per cent biodiesel rather than 5 per cent.

As an addition to the Land Rover Freelander 2 range, Land Rover will also offer customers a 2WD derivative, available in the UK from January 2011. This will be called the Land Rover Freelander 2 eD4 and it will be the most efficient Land Rover ever produced, with fuel consumption of 47.2mpg combined, and CO2 emissions of just 158g/km.

This groundbreaking Land Rover Freelander 2 eD4 is powered by the new 2.2-litre turbo diesel engine, delivering 150PS. It is only available with a six-speed manual transmission featuring Stop/Start technology as standard.

The exterior of the latest Land Rover Freelander 2 gets a new look for 2011. Marked out by a new front bumper assembly incorporating new front fog lap bezels, a new front grille finish, improved headlights and tail lamps, new full width tailgate appliqué and new 18- or 19-inch alloy wheel styles. There are three new colour schemes for 2011 Kosrae Green, Baltic Blue and Fuji White.

Inside the cabin, Land Rover's design team have revised the instrument dials, and there are four new seat styles with the option of a Premium Pack that includes Windsor Leather upholstery, an 8/6 way electric seat, plus premium carpet mats and covered centre stowage.

Land Rover Range Rover Evoque, 2011

Land Rover Range Rover Evoque, 2011

 
 

The Land Rover Range Rover Evoque has turned the much-acclaimed LRX concept car into reality, faithfully capturing the spirit of its landmark cross-coupé design.

Evolution of Range Rover design
The all-new Land Rover Range Rover Evoque takes its inspiration directly from the LRX concept car, which drew worldwide acclaim for its exciting new interpretation of classic Range Rover design cues.
Smart design in conjunction with meticulous engineering allowed the spirit of the LRX concept to be turned into reality without compromising the core Range Rover values of interior luxury, refined performance and all-terrain capability.

Impeccably crafted luxury interior
Beneath its dramatic exterior, the Land Rover Range Rover Evoque provides customers with an impeccably crafted luxury cabin, incorporating the premium quality materials and elegant design expected of a Range Rover interior.

Key product innovations that drive its green performance:
    * Compact size - at 4350 mm, the Range Rover Evoque is 430 mm shorter than a Range Rover Sport
    * Lightweight technologies - advanced materials used throughout the body and chassis
    * Efficient powertrain - state-of-the-art petrol and diesel engines, with high-efficiency features such as direct injection and stop-start
    * Low CO2 technologies - including Electric Power-Assisted Steering (EPAS), smart regenerative charging and optimised transmissions
    * Availability of front-wheel-drive - reducing weight and minimising driveline losses
    * Recycling and re-use - maximising use of sustainable and recycled materials, plus optimising end-of-life recyclability

Distinctively Evoque
Land Rover designers and engineers have developed a host of distinctive and innovative features, to ensure the Range Rover Evoque stands out from the crowd.
Lighting plays a big part in the Evoque's distinctive appeal. First to catch the eye is the powerful signature graphic in the front running lights, created by innovative LED light-blade technology. A similar graphic is repeated in the LED rear lights, with their jewel-like 3D petal design.

There are three main vehicle design themes, each of which has its own distinctive character, exterior treatment and carefully co-ordinated interior package. The three themes are:
    * Pure - combining the stunning concept-car exterior with a stylish, clean interior in neutral colours to highlight the pure, simple forms of the cabin architecture. Soft-touch, wrapped materials on the major surfaces contrast with the real-metal brushed aluminium trim.
    * Prestige - ultimate Range Rover luxury, combining a bespoke exterior that includes unique, 19-inch wheels and sparkling metallic details with an indulgent interior that is almost entirely leather-wrapped. Luxurious duo-tone colour schemes are embellished by premium leather, twin-needle stitching and real wood and metal finishes.
    * Dynamic - bold exterior with 20-inch wheels and unique bumpers, sills, grille and tailpipes for a more assertive, confident stance. Contrasting roof and spoiler colour is a no-cost option, while the premium sports interior offers a darker environment with splashes of bright contrast colour, together with perforated leather seats and unique sports detailing.

Other features available to Land Rover Range Rover Evoque:
    * Park Assist for automated parallel parking
    * Blind Spot Monitoring system
    * Surround Camera System with five digital cameras, including a reversing system
    * Full dual-zone automatic climate control, featuring a Timed Climate park heater facility
    * Hard-drive navigation system
    * DAB/FM/AM/Sirius tuners, with hard-drive virtual 10xCD multiplayer
    * Digital and Satellite TV, and DVD playback
    * Rear-seat entertainment package, with eight-inch video screens, digital wireless headphones and touch-screen remote control
    * Keyless entry system and powered tailgate
    * Adaptive headlamps with auto headlamp dipping
    * Heated windscreen, front seats and steering wheel

Classic Range Rover design cues, with a bold new interpretation
The Evoque's bold exterior features exciting new interpretations of classic Range Rover design cues, including the signature clamshell bonnet, the floating roof and the solid 'wheel-at-each-corner' stance.

Modern and sporting premium interior
The Evoque's interior takes the strong, clean architecture and premium quality materials of a traditional Range Rover, and applies them in a more contemporary and sporting fashion.
As in larger Range Rovers, the centrepiece of the cabin is the bold intersection between the solid horizontal elements of the instrument panel and the powerful vertical lines of the centre console.

The exquisite quality and craftsmanship of the materials is highlighted by the very contemporary, clean treatment of the interior surfaces, including the flush treatment of the air vents and horizontal roller shutter in the centre console.
Housed under a compact curved binnacle, the instrument cluster enhances the sporting, premium feel of the interior. The twin dials have an expressive three dimensional form with chunky illuminated chaplets and needles, and are set deep in sporty circular housings finished with bright chrome rims.

Range Rover craftsmanship, and Range Rover materials
The Evoque delivers Range Rover levels of quality and craftsmanship in every detail of the car. Particular attention has been given to selecting only the best, premium quality materials, and applying those materials with impeccable taste and care.

Perhaps the most visible example is the luxurious wrapped finish of the upper instrument panel. High series models use premium Windsor leather - beautifully soft high-grade hides which have been hand-picked for their exceptional touch and appearance - impeccably hand-finished with twin-needle stitching.

The fascia mid-section is also leather wrapped; this, together with the lavish leather trim on the door panels and seats, creates the ultimate luxury ambience. In total, over 10m2 of leather - equivalent to more than three full hides - is required to complete each vehicle. Every aspect of the stitching, even down to the size and shape of the needle, is also specified by Range Rover experts, to guarantee an immaculate finish, every time.

Even on models where leather is not specified, the instrument panel is still wrapped with a premium quality, soft-touch textured material with twin-needle stitching, for a sumptuous interior experience.

In bold contrast to the opulent leather and soft-touch surfaces, strong visual highlights are provided by authentic metal finishes on the horizontal strip on the fascia, the surrounds to the vent controls, and the striking curved elements each side of the centre console. Cold to the touch and exquisitely crafted, the metal finishes are a tactile and visual reminder of the superior interior quality.

The fastidious attention to detail in every facet of the Range Rover Evoque's construction can also be illustrated by the thousands of man hours spent finessing the way that all visible parts fit together, ensuring an impeccable quality and consistency of finish.

Turning the LRX Concept into reality
The Land Rover Range Rover Evoque is completely faithful to the style of the stunning LRX Concept, capturing its design almost to the millimetre.

Some of the features that helped to preserve the LRX Concept design include:
    * All-new body structure and suspension subframes, delivering the sleek, low profile of the LRX while providing excellent interior space and the traditional elevated Command driving position, with the full wheel travel required for comfort on- and off-road
    * Adoption of ultra-high-strength Boron steels in the A- and B-pillars to retain the slim profile of the pillars without compromising strength or safety
    * Detailed optimisation of the interior package including pedal positions, fuel tank height and door structures to deliver generous interior legroom and headroom while retaining the low coupé roofline
    * Integrating the radio antennae into the rear spoiler, to avoid the fitment of exterior aerials

Land Rover Range Rover2011

Land Rover Range Rover2011

 

A new, class-leading V8 diesel engine, new 8-speed transmission, two significant Terrain Response upgrades and subtle external styling all combine to ensure the 2011 Range Rover retains its crown as king of the luxury SUV segment.

The LR-TDV8 4.4-litre with parallel sequential turbocharging replaces the outstanding LR-TDV8 3.6-litre and is unique to the Land Rover Range Rover. An all-new 'super-diesel', the LR-TDV8 combines superior power and massive torque with unparalleled levels of refinement. Despite the extra performance, this sublime V8 engine is cleaner too, delivering even lower fuel consumption and CO2 emissions than its predecessor and meeting the stringent EU5 emissions standards. The headline news, though, is that the combined cycle fuel consumption of the new LR-TDV8 4.4-litre is just 30.1mpg, making this the first Land Rover Range Rover ever to better 30mpg.

With 313PS and 700Nm torque, the Range Rover's new powertrain matches power with conscience, reducing CO2 emissions by an impressive 14 percent. The new diesel engine is helped in this respect by its marriage to an impressive new, electronically controlled, ZF 8HP70, 8-speed automatic gearbox tuned by Land Rover engineers to combine silky smooth shifting with exceptionally rapid response and outstanding fuel economy.
Available only on 4.4-litre LR-TDV8 models, this 'smart' transmission integrates with the diesel engine to deliver the most efficient operating regime in all conditions. To reflect the performance of the new 4.4-litre LR-TDV8, diesel models are fitted with the same Brembo-based braking system fitted to the 5.0-litre LR-V8 supercharged model. Providing the immense stopping power required for only the highest performing vehicles, the system comprises 380mm ventilated front discs with unique, lightweight aluminium six-piston opposed action monoblock calipers. 365mm ventilated discs with single piston sliding calipers are fitted at the rear.

A new Exterior Design Pack option gives customers the chance to give their Land Rover Range Rover a more individual look and new colours and wheels have been added to the range.

e_TERRAIN TECHNOLOGIES for reduced emissions
e_TERRAIN TECHNOLOGIES are specifically designed to target emissions and improve efficiency of Land Rover vehicles, without compromising luxury, refinement or all-terrain capabilities.

The 2011 Range Rover gains the remarkably efficient 4.4-litre LR-TDV8 engine which realises a reduction in CO2 emissions of 14 percent from 294g/km to 253g/km compared to the outgoing 3.6-litre LR-TDV8 which it replaces. The new LR-TDV8 also complies with the latest EU5 emissions regulations which significantly reduces emissions of HC, CO2 and NOx.

Increasing the capacity by 22 percent over the 3.6-litre LR-TDV8 equates to a lower specific output than the smaller engine, significantly reducing emissions of engine-out NOx. The new ceramic glow plugs operate 250°C hotter than the previous steel units and are more durable. These factors make it possible to run the glow plugs for a longer period after start-up (100 seconds) and more frequently, improving efficiency and reducing emissions. The LR-V8 petrol was designed to deliver superior low-end torque from the outset and is packed with state-of-the-art efficiency features.

The new ZF 8HP70 8-speed transmission is tuned to take advantage of the LR-TDV8's low end torque with torque converter lock-up being selected as early as possible to reduce slip and energy loss. The wider ratio spread, tall overdriven top gear and the fact that no more than two internal clutches are open at any one time all contribute to improved fuel economy and emissions.

The Land Rover Range Rover's Intelligent Power Management System ensures the alternator is charging the battery (and drawing energy from the engine) at the most efficient times, such as when the vehicle is coasting rather than accelerating. The electrical system is scaled such that the battery only needs to be charged to 80 percent, reducing the workload on the alternator. It also moderates the charge rates in cold weather when the battery is less able to cope with high charge rates, increasing battery life for lower cost and environmental impact.

eTERRAIN TECHNOLOGIES in summary:
    * 4.4-litre LR-TDV8 engine technology
    * Engine optimised for maximum efficiency
    * Capacity increase of LR-TDV8 aids lower emissions
    * Ceramic glow plugs improve efficiency
    * Higher torque, tall gearing
    * Reduced torque converter slip on petrol and diesel
    * Transmission promotes fast engine warm-up
    * Intelligent Power System Management (IPSM) including smart regenerative charging

Despite these dramatic reductions, power and torque have soared, from 272PS and 640Nm, to 313PS at 3,750rpm and a staggering 700Nm torque at just 2,000rpm. More important is the way the power and torque interact with one another for impressive overall performance. Maximum torque is available from 1,500rpm to 3,000rpm but then maximum power kicks in from 3,250rpm to 4,000rpm producing a wall of performance from idle onwards. None of this has been achieved at the expense of refinement though and the 4.4-litre LR-TDV8's power delivery remains silky smooth and whisper quiet throughout the engine speed range.

Parallel sequential turbocharging - summary of advantages:
    * Most of the time only one turbocharger is in use (up to motorway cruising speeds and average acceleration). Because it is a medium, rather than large-sized turbo with variable geometry, response is excellent with no discernable lag.
    * Packaging is excellent, one turbo and manifold below each bank of cylinders.
    * The combination of two turbochargers makes it possible to optimise efficiency and performance at all times.
    * Because one turbocharger is in use most of the time, pumping losses are reduced.
    * More efficient than series turbocharger systems, whose smaller primary turbocharger increases pumping losses and fuel consumption through raised exhaust back pressure.

The third generation common rail fuel injection system mirrors that of the 3.0-litre LR-TDV6 operating at a pressure of up to 2,000bar. Eight-hole piezo injectors, (compared to seven hole in the 3.0-litre LR-TDV6) are further optimised for emissions and contribute to the engine's EU5 status and minimise noise. In the past, common rail fuel pumps were designed to over-supply the injector rails, the surplus being re-circulated back to the tank. This approach raised fuel temperature significantly and meant the fuel had to be cooled before being returned to the tank, wasting energy. The new system supplies fuel on demand, increasing efficiency and reducing the amount of cooling required.

The LR-TDV8's ancillary drive-belts have been reduced from seven ribs to six compared to the outgoing 3.6-litre LR-TDV8, making it possible to reduce the thickness of the pulleys, improving efficiency, saving weight and reducing the length of the engine by 4mm. The use of a stretch belt to drive the fan and a dynamic tensioner for the 6-rib alternator belt does away with any need for adjustment during servicing in both cases.

Smart charging improves efficiency
Clever energy management means no fuel is wasted in the production of energy for the Land Rover Range Rover's electrical systems. Land Rover's IPMS (Intelligent Power Management System) ensures the alternator does no more work - and the engine consumes no more fuel - than is strictly necessary. Rather than maintaining the battery charge state at an unnecessary 100 percent, IPMS aims to maintain the battery at 80 percent charge to avoid the alternator working harder than it needs to. The alternator is configured to charge wherever possible when the car is slowing (rather than when accelerating) recovering kinetic energy in the process. Charge rates from the powerful 220amp alternator (which replaces the 150amp unit of the 3.6-litre) are carefully moderated when cold to prolong battery life.

Safety first and foremost
The Land Rover Range Rover can be optionally equipped with a radar blind spot monitoring system to warn of vehicles and objects in the blind spot area. A Surround Camera system makes life much easier in car parks, as well as for towing and off-road manoeuvring and the patented 'reverse tow assist' provides screen-based guidelines to help with those difficult reversing-while-towing manoeuvres. Emergency Brake Assist and optional Adaptive Cruise Control complete the Land Rover Range Rover's package of active safety features.

Interiors offer unparalleled luxury
The Range Rover's European leather trim for headlining and door casings combined with sumptuous leather seat trim and upgraded waterfall lighting, cosset the occupants in luxury. The 12-inch TFT instrument display provides greater versatility than conventional instruments while the 8-inch Dual View infotainment screen displays a different image to driver and passenger. This means, for example, the driver can view the navigation display while the passenger watches a video.

Since MY2010, Land Rover Range Rover navigation systems have featured hard drive storage for mapping data so there's no need to buy DVDs, while 'towards guidance' supports the junction map and icon-based information with images of the actual road signage you see en-route. The portable Audio Interface supports connection to a wide range of audio storage devices including USB sticks and MP3 players. There's also a dedicated iPod connector port developed exclusively by Land Rover to prevent the iPod coming loose over the roughest terrain.

During MY2010, with chauffer-driven passengers in mind, the already incomparable level of exclusivity for rear seat passenger was further improved by the addition of optional, electronically-controlled, reclining rear seats. Operated by the passenger, the seats have internal heating and cooling functions as well as airline-style winged head restraints and four-way adjustable lumbar support.

The rear seat controls also include a facility for moving the front passenger seat forward to gain extended legroom when the front seat is unoccupied. The luxurious rear-seat passenger environment becomes even more opulent with the addition of laminated rear-door privacy glass which has the added benefit of reducing interior noise levels.

These exceptional levels of comfort are further enhanced when customers choose the option of a Logic 7, 1200W Harman Kardon High Dynamics Audio System. Widely acknowledged as one of the finest in-car audio systems in the world, the Logic 7 has 15 independent channels driving 19 premium quality speakers.
