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.
