Bentley Continental Supersports Convertible, 2011

Bentley Continental Supersports Convertible, 2011




The Bentley Continental Supersports Convertible further strengthens Bentley's supercar range, following the introduction of the Bentley Continental Supersports Coupé in 2009. The new Supersports Convertible, with the same 630PS (621bhp/463kW) twin-turbocharged W12 engine, is the fastest, most potent drop-top Bentley has ever built, offering the ultimate Bentley driving experience in the world's most dramatic convertible.

The inspiration for the 'Supersports' name is the 1925 Bentley Supersports, a race-bred version of the iconic Bentley 3-litre, that delivered 85bhp when more ordinary cars were equipped with a modest 15bhp. It was also the first production car to reach 100mph - extreme performance in its day.

The new, muscular four-seat Bentley Continental Supersports Convertible is unmistakably Bentley in its design and craftsmanship but its interiorsignifies a dramatic re-interpretation of Bentley luxury. Satin-finished carbon fibre,Alcantara™and 'Soft Grip' leather create a unique ambience with a distinctly sporting and contemporary style.

All models in the Continental model range, including the new Bentley Continental Supersports Convertible are now capable of running on both petrol (gasoline) and E85 bioethanol or any combination of the two, reaffirming Bentley's ongoing commitment to make all its cars bio-fuel compatible by 2012. Pioneered by the Supersports Coupe, this FlexFuel technology offers a reduction of up to 70 per cent in CO2 emissions on a 'well-to-wheel' basis, a measure of a fuel's net contribution to the atmosphere, not just tailpipe emissions.

To ensure seamless power delivery, the on-board fuel supply system detects the blending ratio of the fuel in the tank and ensures that power and torque remain constant regardless of the ratio of petrol to biofuel.

The Bentley Continental Supersports Convertible - In Detail
The new Bentley Continental Supersports Convertible is a car that must be driven to be fully understood. Behind the wheel it is immediately clear that a Supersports Bentley is a 'fusion of extremes' - the ultimate in extreme performance, every day practicality and unrivalled hand-crafted luxury.

Bentley's Supersports programme began as an 'under the radar' project exploring the possibilities of weight reduction on the Continental GT Coupé but with more power and torque. The largely experimental project soon crystallised into an official new car programme, driven by the passion and enthusiasm of a small group of Bentley engineers and designers. Now the Bentley Continental Supersports Convertible has received the same focus and the results are equally dramatic. Dr Ulrich Eichhorn, Member of the Board, Engineering explains the thinking behind the project:

A highly focussed, pure Bentley driving experience
With 630PS (621bhp) and 800Nm (590lb ft) of torque from its pioneering FlexFuel engine and new 'Quickshift' transmission, the Bentley Continental Supersports Convertible is the fastest drop-top Bentley has ever built. It accelerates from 0-60mph in 3.9 seconds (0-100km/h in 4.2 seconds) and, conditions permitting, can continue onto a top speed of 202mph (325km/h).

The increased power and torque are transmitted to the all-wheel drive system via an uprated and rapid six-speed Quickshift transmission, which more than halves shift times (to just 93 milliseconds) and maximises the new Convertible's enormous potential. The revised gearbox also has the ability to deliver double downshifts (sixth to fourth gear, for example) and improves acceleration across the entire gear range. To cope with the additional power and torque, the planetary gear set of the ZF transmission is also strengthened.

Positive torque during downshifts is achieved through engine and gearbox electronic controller interaction for extra throttle and fuel injection during the overrun. During transmission upshifts, fuel and ignition are cut momentarily to give faster mechanical shift times through torque reduction, also improving shift quality and durability.

The extreme performance of the Bentley Continental Superports Convertible is matched by precise, agile handling, while retaining class-leading levels of ride comfort and refinement. Developed from the GTC Speed, chassis enhancements include retuning of the electronic Continuous Damping Control (CDC) system, stiffer front suspension bushes and uprated rear anti-roll bar. The Bentley Continental Supersports Convertible also shares its ride height with the GTC Speed, sitting 10mm (0.4in) lower at the front and 15mm (0.6in) lower at the rear than the standard GTC.

The front suspension trailing lever features a new design of hydraulic bush, 33 per cent stiffer than those of GTC Speed, for improved steering response while the uprated rear anti-roll bar provides improved body control and turn-in response.

The retuned CDC system provides enhanced control of body movement to strike the optimum balance between agile handling and ride comfort during all driving manoeuvres. Agility is further sharpened by a 40:60 rear-biased torque split for the all-wheel drive system which reduces understeer during hard cornering and allows the experienced driver to modulate the car's line and balance via precise throttle control.

The 9.5Jx20-inch forged alloy wheels, shared with the Supersports Coupé, offer a weight saving of 10kg (22lb) per car, reducing unsprung and rotating mass while the open 10-spoke design offers superior brake cooling. The rear wheels have a 25mm (1 inch) greater offset resulting in a 50mm (2 inches) increase in the rear track, further benefiting handling and stability.

The lightweight wheels are fitted with 275/35 ZR 20 Pirelli Ultra-High Performance tyres, providing excellent steering response. The standard-fit tyre monitoring system allows the driver to select tyres type and speed range parameters. As well as monitoring pressures, the system warns drivers if their speed is too high for the tyre pressures or if tyre speed ratings are exceeded on winter tyres.

The Bentley Continental Supersports Convertible features an advanced electronic stability programme (ESP) that moderates intervention at low speeds, exploiting the potential of the more powerful engine and enhanced chassis, improving driver interaction and control. The new ESP also provides faster reinstatement of engine torque after intervention, giving the spirited driver greater control. The target slip is increased at greater than 90 per cent throttle to utilise all available longitudinal grip. Corner exit agility is thereby also enhanced for increased driver involvement. Together the chassis, tyre and track changes deliver improved grip, turn-in and agility.

Carbon ceramic brakes are standard fitment and provide a reduction in rotating and unsprung mass of 20kg (44lb) from the front axle, benefiting steering response, grip and ride comfort. The large diameter (420mm front, 356mm rear) lightweight discs and eight-piston calipers offer fade-resistant braking performance with minimal disc distortion under high thermal conditions. Pedal feel is also improved with shorter travel, high effectiveness and a precise pressure point.

Designing the 'extreme' Bentley convertible- where form follows function
The evolution of the Bentley Continental Supersports Convertible's design is very much a case of form following function, with new purposeful sculptural forms signalling the engineering changes beneath the skin. Key engineering-led design changes to the Supersports include:
    * Revised front air intakes and new bonnet vents to improve airflow and cooling
    * Flared rear wings to accommodate wider rear track
    * Discreet bootlid spoiler benefitting aerodynamic balance at high speeds

The increased power and torque of the W12 engine necessitated an additional 10 per cent airflow to the twin turbocharger intercoolers and cooling system. With extensive use of Computational Fluid Dynamics techniques, Bentley's designers responded with a purposeful and dramatic style, featuring large vertical intake apertures. Twin bonnet vents were added to ensure positive air extraction.

Similarly, all-new flared rear wings that accommodate the 50mm (2 inches) wider rear track are designed to emphasise the powerful stance of this ultra-high performance Convertible. The resultant Bentley Continental Supersports Convertible style combines the looks of the graceful Continental GTC with a wide, low and muscular appearance that reflects its more extreme character.

Bentley Continental Supersports, 2010








The Bentley Continental Supersports is the fastest and most powerful Bentley ever. It is the extreme Bentley, a muscular two-seater that delivers supercar performance and a highly focused driving experience. The Bentley Continental Supersports is also the first Bentley capable of running on both petrol (gasoline) and biofuel, pioneering the use of FlexFuel technology in the luxury sector. This represents stage one of the company's commitment to make its complete model range compatible with renewable fuels by 2012. Available worldwide from autumn 2009, the Bentley Continental Supersports will be FlexFuel compatible in the majority of markets from launch with North American cars offering the capability by summer 2010, following regulatory approval.

The Bentley Continental Supersports began as an 'under the radar' project exploring the possibilities of weight reduction on the Bentley Continental GT but with more power and torque. A largely experimental process crystallised over a period of 24 months into an official new car programme, driven by the passion and enthusiasm of a small group of Bentley engineers and designers. The results are dramatic. With 630PS (621 bhp) and new 'Quickshift' transmission that halves shift times, the Bentley Continental Supersports sets new performance benchmarks for Bentley. It accelerates from 0-60 mph in 3.7 seconds (0-100 km/h in 3.9 seconds) with a top speed of 204 mph (329 km/h).

The supercar performance is complemented by an array of chassis enhancements including retuned steering and suspension, utilising lighter weight components, retuned dampers and anti-roll bars. Agility is further sharpened by the 40:60 rear-biased torque split for the all-wheel drive system, a wider rear track, bespoke lightweight 20-inch alloy wheels and a unique electronic stability programme. Carbon ceramic brakes are standard fitment, benefiting steering response, grip and ride comfort, while saving weight. Overall, the engineering team have achieved a weight reduction of 110 kg (243 lb) compared with the Bentley Continental GT Speed.

The evolution of the Bentley Continental Supersports' design is very much a case of 'form following function' with new purposeful sculptural forms signalling the engineering changes beneath the skin. For example, the increased power and torque of the W12 engine necessitated additional airflow to the twin turbocharger intercoolers and cooling system. Bentley's designers responded with a purposeful and dramatic style that features large vertical intake apertures and twin bonnet vents. Similarly, new flared rear wings that accommodate the 50 mm (2 inches) wider rear track are designed to emphasise the powerful stance of this ultra-high performance coupe. The resultant Supersports style combines the looks of the iconic Continental GT with a new and distinctive appearance that reflects its more extreme character.

The Bentley Continental Supersports is further distinguished from its Continental coupe stable mates by a unique dark-smoked steel finish to all exterior 'brightware', including front grilles, lamp bezels, window surrounds and wheels. A complex 'Physical Vapour Deposition' process is applied to all stainless steel components to give a lustrous and highly durable finish. A car industry first, this process is normally used as a coating on industrial tools, watches and even hip replacement joints.

Fully embracing the extreme spirit of the Supersports, Bentley's interior designers have created a unique ambience. The cockpit represents a dramatic reinterpretation of Bentley interior design in which carbon fibre and Alcantara not only convey a sporting and contemporary style but also reduce weight. The Bentley Continental Supersports is a strict two-seater featuring all-new lightweight sports seats with carbon fibre clamshell rear panels. In the rear compartment, the seats are replaced by a stowage deck with a carbon fibre luggage retaining beam. The new interior also provides a showcase for the skills of Bentley's craftsmen and women at the company's factory in Crewe, England. Signature premium grade leather and brightware are complemented by carbon fibre panels, replacing traditional wood veneers.

The Bentley Continental Supersports is capable of running on either petrol and E85 biofuel or any combination of the two. E85 biofuel can offer a reduction of up to 70 per cent in CO2 emissions on a 'well-to-wheel' basis. Well-to-wheel is a measurement of a fuel's net CO2 contribution to the atmosphere, not just tailpipe emissions. It is a way of quantifying how much CO2 a fuel emits from its growth or extraction (well) to its combustion or deployment (wheel). It includes refinement, distillation and transport of the fuel. The fuel supply system detects the blending ratio of the fuel in the tank and ensures that power and torque remain constant regardless of the ratio of petrol to biofuel. The result is seamless power delivery in the Bentley tradition.

The 'Supersports' name is inspired by the original two-seater 3-litre Supersports model introduced in 1925, itself an evolution of the 3-litre Speed. The lightweight, 85 bhp Supersports was the first production Bentley to reach 100 mph and was also renowned for the application of Le Mans-winning race technology.

Bentley Continental Flying Star, 2010

Bentley Continental Flying Star, 2010





An interesting initial creative process emerged involving parameters for design, proportions, vehicle concepts and - last but not least- feasibility and technical factors. Many steps from design to execution were shared with the customer, who contributed with his own ideas and taste to personalise the project and create a unique automobile. A basic idea was formed by the desire to diversify Bentley's very successful Continental model range, and to explore new concepts.

The transformation of a 2-door coupé, by expanding the roof line and enlarging the interior dimensions, has led to a design concept baptised as shooting brake: a sports car featuring enough space to join a hunting party or a golf tournament with elegance and efficiency. Touring Superleggera explored the same field back in 1966, resulting in the amazing Lamborghini Flying Star II prototype. It was a dramatic interpretation of a sports car based on a new 2-volume design, safeguarding the dynamic performance. The Flying Star reference is a Touring parameter of sportive elegance, applied to many famous cars since the companies' start in 1926.

Flying Star in 2010 - the Bentley challenge
The Bentley Continental GT range set innovative and high standards for a new generation of very sophisticated Grand Tourers. As such, this model triggered the imagination of automotive designers and coach builders elsewhere. The GTC convertible, featuring a very rigid platform, proved to be a fully congruent basis to Touring Superleggera's plans for the new Bentley Continental Flying Star.

The new project required the modification of a number of external dimensions starting from the car's A-pillar backwards: extended roof line, a wider section including the doors, new aluminium door skins and a new all-aluminium, electrically operated tailgate. It also includes a completely new rear compartment with two foldable rear seats and a variable loading space.

This long list of modifications and transformations had to be paired with, and to remain fully compatible to the basic car's technical layout and components. Given the sophistication of the basic car, a new challenge was laid out for Touring's craftsmen and engineers. The final result proves that special coach building can live on well into the 21st. century working with respect to the original manufacturers.

Touring Superleggera is particularly proud of the fact that the complete productive cycle of the special coach building process was realized in their workshop near Milano. Modern body engineering went hand in hand with traditional handicraft skills, maintaining the highest quality directives for the final product.

Project Engineering
The body engineering processes at Carrozzeria Touring are aimed at safeguarding key parameters for quality, safety and feasibility, within the perspectives of low-volume automotive production. The project went through 1:4 and 1:1 modelling, based on the CAD and CATIA data from the basic vehicle. This digital basis resulted in a milled 1:1 master model and a number of 1:1 moulds for the manufacturing of the new external skin, and for important new body components. The rear bodywork was reinforced with an integrated structure between the rear suspension domes, functioning both as roll bar, and as support for the new, extended roofline.

All structural additions and modifications were thoroughly studied, using advanced simulation methods and FEM-analysis. As a parallel process, these data served for the homologation of the structural changes, including the new foldable rear seats. An important number of hard points from the basic car could be saved and carried-over. The engineering team at Carrozzeria Touring was particularly pleased with the quality assurance support from Bentley engineers.

Design
'Variations on a theme' not rarely implicate a larger design challenge, than starting-off with a white sheet of paper. The basic mission was to create a body incorporating the essence of Touring elegance and harmony, while clearly recognizable as a Bentley. This task was challenging because a fully new volume had to be added to the GTC basis. The proportions were totally new, but the overall design had to be kept consistent. That is why only the section in front of the car's A-pillar, including the windshield has been maintained.

Viewed from the rear, the new tailgate dives between the wide rear wings. The oval rear light chrome bezels are a reference to Bentley fastback cars of the '50. The side view features a low roof, prominent quarter panel shoulders and wide wheel arches, suggesting perfectly mastered energy.

The Touring Superleggera designers were challenged by the target to give the new interior equal elegance, whether the back of the rear seats are folded or not. The solution was to design an "S" shaped trim of the rear quarter panels linking the passenger area to the rear luggage area. The beige and dark green leather contrast also adds to this visual unity.

First time ever in this class and size, the twin individual rear seats fold completely to create a flat loading surface more than 2m long with 1200lt capacity. This is instrumental to fulfill the functional mission profile, which requires loading in full comfort a wide array of leisure equipment, including 4 full golfing bags with the rear seats up. An example of bespoke finish is the woven leather boot carpet offering superior endurance and coordinated with the special luggage set.

The overall result is perfectly in line with the Touring and Flying Star heritage: a timeless shape, a design statement combining elegance and sportiveness, with a strong and unmistakable own personality and individuality.

Manufacturing
When digital technologies are blended with traditional manufacturing skills, a fascinating process emerges that is typical for Touring Superleggera. A discriminating factor for traditional coach building was and is the vast amount of handwork that is involved in the creation of a new body. In this process, multiple practical solutions are also found for a wide variety of minor technical issues. This includes quick, practical solutions based on years-long experience, common sense and an expert eye.

The result is a final product entirely produced within the high quality parameters of today's automotive industry.

From the A-pillar backwards, new exterior body panels were hand shaped in steel - including the roof, new wider rear wings, and the internal reinforcements of the complete rear section of the car. Aluminium was used for the door skins, and for the complete rear bonnet including its structure. New, handmade brightwork was added according to the new exterior design.

The all new rear compartment required shaping of the foldable rear seats and a full set of interior panels, leather trimmed with meticulous care. Wide leather hides were selected with great attention to provide uniform finish to the vast continuous surfaces.

After inspection, the body in white was prepared and painted in the Touring state-of-the-art paint facilities. The final result underwent again a special final quality audit.

Performance
The Bentley Continental Flying Star by Touring inherits the chassis of the Continental GTC. The 6-liter, W12 engine is available either in the 560HP version which delivers 650NM of torque at 1600rpm or the GTC Speed variant which delivers a massive 750Nm from 610HP. The car exhibited at the 2010 Geneva Motor Show featured the GTC Speed specifications.

Performance braking, cornering and traction functions mesh together to provide precise and immediate driving control under extreme or difficult conditions.

Self-adjusting air springs and electronic dampers operate independently for each wheel. Allwheel drive promotes advanced traction.

Homologation
The model is CEE homologated according to the new low-volume production directive. For the first time since its introduction, the type approval was awarded without destructive test, using simulation and FEM-analysis.

Future Programme
Touring Superleggera undertakes a limited production run of up to 20 units of the Bentley Continental Flying Star. This series will be exclusively built to special order and customer specifications. The car is offered at a basic price of € 590.000 when based on a Continental GTC - 560 PS. Other versions on request.

The car will be serviced at the Bentley dealers. Bentley Motors and Touring Superleggera have developed a special mutual warranty program, which safeguards warranty clauses for both the basic car, and the transformation by Touring.

Personalisation
The customers are actively involved in the early stage to choose the specifications of their own unique automobile, ranging from bespoke cabinetry and trim to a wide choice of dedicated options. The accessory collection includes the Touring designed luggage set coordinated with the boot trim, and the distinctive Borrani X-Ray spoke wheels.

Blending advanced technology with craftsmanship, Borrani 20" 9.5j X-Ray spoke wheels provide distinctive design, precision and comfort. Featuring monolithic spun aluminium rim and hand assembled steel spokes, they can be tailored to the car's painting and finish.

Bentley Continental GT Speed, 2008

Bentley Continental GT Speed, 2008

 


The Bentley Continental GT Speed is the most powerful production Bentley ever and the first to top 200mph (322km/h). A potent addition to the company's highly successful Continental series, the GT Speed extends the appeal of the Continental GT coupe to driving enthusiasts who place a high value on outright performance and agile handling.

The exterior style of the new Bentley Continental GT and GT Speed models is defined by a wider, lower air intake and more upright radiator grille that also provide increased airflow to the more powerful GT Speed. Its 600bhp (610PS) W12 engine develops 15 percent more torque and nine percent more power than the standard Continental GT, while engine efficiency is optimised by the use of lower friction, lighter-weight components and a new engine management system. The resultant performance is exceptional, with a top speed of 202mph (326km/h), a zero to 60mph sprint time of just 4.3 seconds (0-100km/h in 4.5s) and effortless overtaking capability.

Complementing the Bentley Continental GT Speed's high performance is its unique chassis tune that delivers tauter handling and improved agility, with new, wider 9.5J 20-inch wheels and bespoke performance tyres as standard fitment. Fade-resistant carbon ceramic brakes are available as an option. Subtle design touches, including a dark-tinted front grille and larger sports tailpipes, reinforce the sporting character of the Bentley Continental GT Speed.

Inspiration for the Bentley Continental GT Speed came from the legendary 'Speed' models that first appeared in 1923. The standard Bentley 3-litre had already established Bentley's engineering superiority in terms of roadholding, handling and braking, but W.O. Bentley, the company's founder, recognised the market potential for a more potent version aimed at the enthusiast driver who demanded superior performance. His response, the 3-litre 'Speed Model', complete with twin SU carburettors and a higher compression ratio engine, became one of the most coveted of all Bentleys.

Both the Bentley Continental GT Speed and the 552bhp (560PS) Continental GT benefit from internal efficiency improvements to deliver reduced fuel consumption and CO2 emissions. The Continental GT remains outstandingly quick - its top speed is unchanged at 198mph (318km/h), with a 0-60mph sprint time of 4.6 seconds (0-100km/h in 4.8s).

The all-wheel drive Bentley Continental GT changed the face of the luxury coupe market and attracted a wider audience to the Bentley marque. It also represented the first step in Bentley's renaissance, positioning the company at the pinnacle of both technology and consumer aspiration. Since its launch, demand for a sportier version of the Continental GT was met by the successful introduction of the 2005 GT Mulliner Driving Specification and the limited edition GT Diamond Series in 2006, to celebrate 60 years of Bentley at Crewe. Now, with the launch of the Bentley Continental GT Speed, customers will enjoy even greater choice. Bentley Chairman and Chief Executive Dr Franz Josef-Paefgen welcomes the expansion of the Continental GT model offering: "The Continental GT is a highly successful, modern-day Bentley icon. The new Bentley Continental GT Speed, with its harder-edged character and sportier driving experience, builds on this success."

Engine enhancements for all Bentley Continental GT models
At the heart of both Bentley Continental GT models is the Bentley 6-litre, twin turbocharged W12 engine, the most compact 12-cylinder engine in production. The 48-valve head employs four camshafts and continually variable valve-timing. Power is transmitted via a ZF six-speed automatic transmission.

A host of engine and transmission enhancements have been introduced on the 552bhp (560PS) Bentley Continental GT to enhance both the refinement and efficiency of this high technology powertrain. These :

    * New crankcase design to reduce internal losses.
    * More efficient catalyst and exhaust system for improved emissions.
    * Lighter weight single chain drive for camshaft.
    * New engine management system and faster response cam sensor.

For the Bentley Continental GT, the engine continues to produce 552bhp (560PS / 412kW) at 6100 rev/min and a maximum torque of 650Nm (479lb ft) from1600 rev/min. The twin, low-inertia turbochargers are a key factor in producing the flat torque curve, characteristic of every Bentley.

A new higher output of the W12 engine is specified for the Bentley Continental GT Speed, sharing engine efficiency improvements with the GT model. New lighter weight con rods enhance engine response, while new pistons, with anodised compression ring grooves, are designed to withstand increased cylinder pressures. Together with a recalibrated version of the new engine management system, the Bentley Continental GT Speed develops nine percent more power than the GT - 600bhp (610PS) at 6000 rev/min. The maximum torque of 750Nm (553lb ft) at 1750 rev/min represents an increase of over 15 percent versus the standard engine. As a result, the Bentley Continental GT Speed becomes the first production Bentley to top 200mph (322km/h), with a V-max of 202mph (326km/h).

Both the Bentley Continental GT Speed and GT models now produce lower CO2 emissions of 396g/km, down from 410g/km, an improvement of 3.5 percent. Fuel consumption is improved by a similar amount.

Brian Gush, Director, Chassis and Powertrain, says the two new models offer something for every Bentley enthusiast: "The Continental GT will continue to be the benchmark for the luxury coupe class, offering an unrivalled blend of performance and refinement. The new Bentley Continental GT Speed is a true driver's car with immense power and superb handling."

The advanced ZF 6HP26 six-speed automatic gearbox has the ability to lock up its torque converter during normal driving conditions replicating the immediacy of a manual transmission while maintaining the smoothness of an automatic. A manual override function allows clutchless manual changes via the gearlever or steering wheel paddles.

Providing huge levels of grip and stability in all weather conditions, the all-wheel drive system harnesses the prodigious power and torque of both the Bentley Continental GT and GT Speed coupes. The system uses a central Torsen differential and a differential on both the front and rear axles providing a standard 50:50 torque split. This front to rear ratio is variable depending on the available grip and the system can sense slip of less than one percent and react by apportioning the engine's torque to either the front or rear axle.

The advanced electronic stability programme (ESP) has been uprated to ESP 8.1 for both models. The Bentley Continental GT has a new "Sport Traction" mode that moderates ESP intervention at low speeds, providing a greater degree of driver interaction and control. This is particularly beneficial from standing starts, for example when pulling away uphill on low traction surfaces.

The Bentley Continental GT Speed offers a new 'Dynamic Mode' that allows increased wheel slip at higher speeds than the 'Sport Traction' mode on the standard chassis. Torque is reinstated more quickly after the traction control system is triggered, giving the spirited driver a greater sense of control and the ability to exploit the full potential of the new engine.

Highly tuned suspension for outstanding handling

Chassis, suspension and steering modifications for both the Bentley Continental GT and GT Speed models ensure they have the handling to match their formidable powertrains. Both are suspended on double wishbones at the front and a trapezoidal multi-link system at the rear. Much of the suspension is made from lightweight aluminium. The Bentley Continental GT Speed model also benefits from a solid-mounted front subframe, while high-stiffness aluminium front uprights are common to both models. Together with stiffer rear suspension bushes these deliver even sharper handling characteristics. The Bentley Continental GT Speed also features modified front and rear anti-roll bars to minimise understeer and optimise handling balance.

Self-levelling air suspension that constantly monitors and adjusts the ride height and damping according to road conditions is common to both models, although the Bentley Continental GT Speed is engineered to sit 10mm lower at the front and 15mm lower at the rear to improve handling dynamics. Uprated springs and dampers, together with revised software control, further improve the agility and body control of the Bentley Continental GT Speed.

All-new 9.5Jx20-inch alloy wheels with bespoke Pirelli P-Zero tyres have a major effect on the GT Speed's steering and grip levels. The wider wheel and reduced tyre wall profile improve the tyre's lateral stiffness giving noticeably sharper steering response and feel. The new Pirelli performance tyres are developed specifically for the Bentley Continental GT Speed and benefit from a unique construction and rubber compound for enhanced levels of grip.

Both the Bentley Continental GT and GT Speed benefit from changes to the rack and pinion steering. Revisions to the system's hydraulics reduce friction and improve steering feel, while a new version of the speed-sensitive Servotronic system also increases levels of feedback to the driver.

Secondary ride levels - the response of the car to poor road surfaces, pot holes or cats' eyes, for example - have been improved on the 552bhp Bentley Continental GT model with the addition of low friction dampers. And even though the new Bentley Continental GT Speed has stiffer, lowered suspension its ride quality is on a par with the 2007 Bentley Continental GT.

The Bentley Continental GT and GT Speed are both equipped with the largest brakes of any production passenger car on sale today. The ventilated front discs have a 405mm diameter and are 36mm thick. Ventilated discs are also used at the back, with a diameter of 335mm and a thickness of 22mm.

For both models, the performance boundaries are further extended by Bentley's optional carbon/silicon carbide brake system. Boasting 420 x 40mm carbon-silicon carbide, cross-drilled front discs and 356 x 28mm rears, with eight-piston callipers, the new brakes are even larger than the standard system. The system provides a 20kg reduction in rotating and unsprung mass, benefiting steering response and handling.

The lightweight, fade-resistant braking system minimises disc distortion under high thermal conditions. Under normal driving conditions the brake discs will last the lifetime of the car. Furthermore, brake pad life is doubled compared with the standard braking system.

Complementing the braking systems of both Bentley Continental GT models are sophisticated safety systems, including Hydraulic Braking Assistance (HBA), anti-lock braking (ABS), drag torque control (MSR) and Electronic Brakeforce Distribution (EBD). The latter monitors the level of grip available to each tyre and apportions braking force accordingly. This not only helps reduce stopping distances but also greatly enhances the control enjoyed by the driver under heavy braking.

Subtle changes to acclaimed coupe design

The Bentley Continental GT Speed is distinguished from the Continental GT by its dark-tinted chrome matrix grille to the main and lower air intakes. Bright chromed grilles may be specified at no extra cost. At the rear, a black lower bumper valance and wider, rifled exhaust tailpipes emphasise the Bentley Continental GT Speed's sporting character, reinforced by new multi-spoke 20-inch sports alloy wheels. As an option, these may be specified with a dark chromed finish.

The Bentley Continental GT Speed's cabin is based on that of the Mulliner Driving Specification (a cost option on the standard GT). It includes a choice of veneers (Burr Walnut, Dark Stained Burr Walnut and Piano Black), Diamond-quilted hide seats with embroidered Bentley emblem, indented hide headlining, a sports alloy gearlever, three-spoke multi-function sports steering wheel, drilled alloy foot-pedals as well as 'Speed' logos to the treadplates.

A range of Mulliner options provide further opportunities for personalisation including fascia panels, header and centre console in bright aluminium or, unique to the Bentley Continental GT Speed, dark tint aluminium (compatible only with Dark Stained Burr Walnut veneer or Piano Black veneer and single tone interior colour scheme). The Bentley Continental GT also benefits from a new Bentley 'B' brake pedal.

Bentley Brooklands

Bentley Brooklands 2008

The Bentley Brooklands is a stunning new model that marks the company's return to the luxury coupé market and reaffirms its reputation as creator of the world's most exclusive coupés. It is the ultimate Bentley: a stylish, four-seat, grand touring coupe with classic British proportions and muscular performance.

Bentley's chairman Dr Franz-Josef Paefgen describes the motivation behind the new coupé: "Bentley's proud sporting pedigree, forged by the exploits of the immortal 'Bentley Boys' on the famous Brooklands racetrack in the 1920s, was the inspiration for our new coupé, capturing all the style, power and splendour of that era."

Sporting design cues are matched by the phenomenal performance engineering of Bentley's legendary Crewe-built V8 engine. The new Bentley Brooklands possesses the most powerful V8 the company has ever produced - a 530bhp, twin-turbocharged 6.75-litre unit that also produces a prodigious 1050Nm of torque.

Each Bentley Brooklands coupé will be hand-assembled, employing traditional coach-building techniques and the craftsmanship skills in wood veneer and leather hide for which Bentley is renowned. To ensure exclusivity, lifetime production will be strictly limited to just 550 cars, with deliveries expected to start in the first half of 2008.

Exterior Design: Classic British Proportions
Bentley's rich coupé heritage provided the stimulus for Director of Styling, Dirk van Braeckel and his design team. For van Braeckel, the task was very clear: "To create a powerful, muscular and rakish grand touring coupé with classic British proportions, in the finest Bentley tradition."
"The Brooklands' beautiful flowing lines are testament to the traditional coach-building skills and craftsmanship of Crewe's highly talented workforce."

The 'floating' rear screen is a contemporary take on traditional coachbuilt Bentleys. The lower edge of the screen sits well above the upper edge of the boot lid to provide a flowing, flawless line to the back of the car. This can only be achieved by individually hand-welding the rear wings to the C-pillars.
The fitment of 20-inch diameter wheels as standard, signalling the surefooted, robust and dynamic character of the new model, reaffirms the powerful stance of the new Bentley coupé.
Interior Design: Peerless Craftsmanship with a Sporting Character
Dirk van Braeckel describes the mission for the Bentley interior design team: "To create the perfect Bentley coupé: sumptuous hand-crafted luxury with a distinctly sporting character."

As in every Bentley, peerless craftsmanship is to the fore, enhanced by the warmth and richness of the finest natural materials. To tailor for their individual requirements, customers may choose from an extensive palette of hides, veneers, carpet tones and seat belt colours.

Its four-seat architecture and deeply bolstered seats lend the Brooklands' interior a distinctly sporting atmosphere, complemented by design accents such as aluminium foot pedals and footrest. A new, single-piece, hide-trimmed roof lining flows uninterrupted from the front windscreen all the way to the rear of the car, mirroring the long, sleek profile of the elegant exterior.

The interior designers sought to offer the very highest levels of comfort and legroom, in true Bentley grand touring tradition, while the pillarless window design enhances the feeling of space.

The Bentley Brooklands' cabin is wider both front and rear than the previous Bentley Continental R coupé - the rear by 10 percent - and it easily exceeds the interior leg, knee and headroom of any luxury coupe on sale today. This allows four adults to be accommodated in supreme comfort. Individual rear seats with electrically operated sliding cushions, set further back than on the Azure, are separated by a new centre console, incorporating both storage and cup holders.
Most powerful Crewe-built V8 ever - 530bhp, 1050Nm
Beneath its muscular, rakish, coach-built body lies the most powerful Crewe-builtV8 engine ever produced, developing 530bhp. Maximum torque is an astonishing 1050Nm, the highest ever developed by a production V8 engine. Although performance figures are subject to final confirmation as part of the on-going development programme, the new Bentley coupé will deliver supercar levels of in-gear acceleration combined with Arnage refinement.

At the beginning of the project, Dr Ulrich Eichhorn, Member of the Board, Engineering, tasked his power train specialists to deliver an extraordinary driving experience in the Bentley coupé tradition: "Exhilarating, effortless, accessible performance for those truly passionate about their driving was our prime objective."

Launched in the Bentley S2 saloon in 1959 with a capacity of 6.23 litres, the legendary, Crewe-built V8 engine has continually evolved. The first V8 was very advanced for its time with an all-aluminium construction, a five-bearing crankshaft and a well-supported camshaft, producing nearly 200bhp and 400Nm of torque. The result was a light and supple powertrain that produced maximum torque at low engine speeds, the hallmark of every Bentley ever produced.

1969 saw the capacity grow to 6.75 litres, where it remains to this day, but by far the most significant change came in 1982, with the introduction of a turbocharger to create the near-300bhp Mulsanne Turbo, a car that transformed the image of Bentley. In 1999, the single turbo engine, by now featuring port injection and charge cooling, was installed in Arnage, with twin turbos arriving in 2002, developing up to 450bhp.

The V8 engine is mated to a six-speed transmission with strengthened casing that transforms the way in which both parts of the drive train communicate. A sophisticated, locking torque converter and ESP system ensure that the driver can readily access the prodigious power. A semi-automatic function allows manual gear selection for even greater driver control.

Bentley GTZ Zagato Concept

Bentley GTZ Zagato Concept




The Zagato Atelier takes great pleasure in introducing the Bentley GTZ, the latest in a long line of collaborations with the very best British car manufacturers over the Milanese Atelier 's 89.

Following on from the recent presentations of the Ferrari 575GTZ in 2006 and the Maserati GS Zagato at the Villa D'Este in 2007, the Bentley GTZ is a neo-classic Zagato interpretation of the style of a British GT.

The project was conceived during a discussion between Dr. Ing. Franz Josef Paefgen, CEO of Bentley Motors Limited and Dr. Andrea Zagato, President of Zagato at the Pebble Beach Concours D'Elegance in 2006. At a 'Tribute to Zagato' presentation, Zagato showed a selection of 50' 60's models, near by the recent berlinettas presented during the last 3 years. Dr. Paefgen was struck by the beauty of those cars and reminded of the historical significance of the art of the Carrozzeria (coachbuilders) which was both being maintained and carried forward by Zagato.
Starting from the styling cues of the last neo classical coupes, which became milestones of Zagato design in the new millennium, the challenge was to apply the same design language to a completely different proportion of vehicle: the Bentley Continental GT Speed.

Even with many technical restrictions and carry-over parts in order to maintain the basic functions of this extremely sophisticated vehicle, the Zagato design team managed to give a distinctive and attractive character to the Zagato coupe.


Double-bubble roof, round tail with all new rear combination lamp are harmoniously integrated in to an imposing body adding a more aggressive and sharp feeling without losing the absolute solidity which is part of the great charm of the original coupe. The same time the hand painted pin-stripe coordinated with the interior colour adds a refined and exclusive elegance to the extrovert body lines helps to make the look of this car appropriate to be special limited-production model born between two great automotive cultures: Bentley and Zagato.
