Bentley Brooklands, 2008

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.

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

While the new Bentley Brooklands is influenced by Bentley's fine coupé lineage, its design and engineering are thoroughly contemporary. The proportions of long bonnet, short front overhang and long rear overhang achieve the design objective perfectly, while the low roofline, steeply raked screens and pillarless side glass convey both power and movement.

As the Bentley Brooklands will be built in very limited volume, the designers were able to introduce unique features that necessitate specialist coach-building techniques, as Programme Director, Ashley Wickham, reveals: "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, for example, 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

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.

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.

For the 2007 model Arnage, the V8 engine saw a step-change in performance and refinement which became the starting point for the new Bentley Brooklands. A re-profiled camshaft and new, low-inertia turbochargers, which operate with greater efficiency at lower engine speeds have resulted in reduced turbo lag, enhancing that prodigious wave of torque at any revs, the hallmark of a true Bentley. These changes extend the power potential of the V8 in the Arnage to 500bhp and 1000Nm of torque. For the Bentley Brooklands, further component optimisation and engine calibration ensure record power and torque levels from this hand-assembled engine.

As with the latest Arnage, 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 Continental GTC Speed

The new GTC models share a fresh frontal appearance. The radiator grille is more upright with a more pronounced square edge, accentuating the Bentley profile, and bolder lower air intake. These latest models are further distinguished by chrome headlamp bezels, the availability of two new exterior paints and a new colour hide.

Introduction of the new Bentley Continental GTC range builds on this success with a subtle evolution of its distinctive style and a range of technical and feature enhancements benefiting comfort and customer choice. The appeal of the GTC is further strengthened by the addition of the new 600bhp (610PS) Bentley Continental GTC Speed model. It is Bentley's most powerful convertible ever and inspired by Bentley's legendary 'Speed Models' from the 1920s.

The GTC's chassis and exceptionally rigid steel body have proved more than capable of coping with the power of the 552bhp (560PS) 6-litre W12 engine. For the new Bentley Continental GTC Speed, twin-turbocharged W12 now develops 600bhp (610PS) that delivers true 200 mph (322 km/h) performance, with the roof up, with exhilarating, effortless acceleration. Even with the roof down the Bentley Continental GTC Speed can reach 195 mph (312 km/h).

The Bentley Continental GTC Speed is visually distinguished by subtle design enhancements which emphasise its higher performance credentials. At the front, the radiator and lower air intake grilles feature a dark tinted matrix as standard. Larger diameter 9.5J x 20-inch, multi-spoke alloy wheels with Bentley-bespoke Pirelli PZero ultra-high performance (UHP) tyres, lowered and uprated suspension, wider twin-rifled exhaust tail pipes and a new boot-mounted lip spoiler that enhances high speed aerodynamics, reinforce the sporting character of the Speed model.

The GTC Speed's 600bhp (610PS) W12 engine develops 9 per cent more power than the standard GTC. However, it is the 15 per cent increase in torque that really distinguishes the Speed model, which now develops an impressive output of 750 Nm (553lb ft). This is achieved across virtually the complete rev range, from just 1700 to 5600 rev/min, delivering that characteristic Bentley wave of torque.
The 0-60 mph sprint is despatched in a mere 4.5 seconds (0-100km/h in 4.8 seconds) and 0-100 mph in 10.6 seconds (0-160 km/h in 10.5 seconds).

Enhanced powertrain delivers more power and torque
Both Continental GTC models are powered by Bentley's 6-litre, twin-turbocharged W12 engine which is produced exclusively at the company's Crewe engine plant. The Bentley W12 is the most compact 12-cylinder engine in production with 48 valves and 4 camshafts with continually variable valve timing. Power is transmitted via a ZF six-speed automatic transmission.

The Bentley Continental GTC Speed is powered by Bentley's W12 engine in its most powerful, 600 bhp (610PS) form. It develops 15 per cent more torque and 9 per cent more power than the 552bhp (560PS) standard Bentley Continental GTC.

The Engine efficiency improvements result from the use of lower friction, lighter-weight components and a new engine management system, while twin, low inertia turbochargers with minimal turbo lag contribute to the W12 engine's flat torque curve. In 600 bhp (610PS) form, the W12 develops a maximum torque of 750 Nm (553 lb ft) from 1700 rev/min all the way up to 5600 rev/min. The GTC Speed engine is visually differentiated by the 'crackle black' finish to the intake manifold.
This endows the Bentley Continental GTC Speed with a top speed of 200mph (322 km/h) with the roof-up and a 0-60mph sprint time of just 4.5 seconds (0-100 km/h in 4.8 secs). It also accelerates from 0-100 mph in just 10.6 seconds (0-160 km/h in 10.5 seconds).
The six-speed transmission can be left in two fully automatic modes (Drive and Sport) or used as a clutchless manual where the driver can change gears sequentially, via either the gearlever or paddles mounted behind the steering wheel.

The advanced continuous all-wheel drive system of both GTC models provides exceptional traction in all weathers. The drive is transferred between the front and rear axles via a highly sensitive centre Torsen differential. If the differential detects a deviation in torque demand between the two axles it automatically sends more power to the wheels with greater grip.

Both the GTC and GTC Speed also feature an advanced electronic stability programme (ESP 8.1). The 'Sport Traction' mode for the GTC moderates ESP intervention at low speeds, benefiting driver interaction and control, particularly on low traction surfaces. The 'Dynamic Mode' of the GTC Speed allows increased wheel slip at higher speeds compared to the standard chassis. This ensures that torque is reinstated more quickly, allowing the driver to exploit the full potential of the engine.

A luxury convertible with outstanding ride and handling
The Continental GTC's steel body has an exceptionally rigid torsional stiffness of around 30Hz that not only minimises 'scuttle shake' but provides a very stable platform for the aluminium-intensive suspension system, optimising its performance. Despite the boost in power and torque for the GTC Speed model, no changes to the body structure were required.
For the 552bhp (560PS) GTC, new low-friction dampers provide improved secondary ride (the response of the car to poor road surfaces) and even greater levels of comfort.

The Bentley Continental GTC Speed has a range of dynamic enhancements that deliver a more sporting, open-top Bentley driving experience. The retuned Continous Damping Control (CDC) system ensures that the body response matches the inputs from the new sports wheels and tyres, while improved body control reduces pitch and roll when cornering enthusiastically. In addition, stiffer rear axle bushes deliver better axle control and turn-in response.

The GTC Speed's suspension is lowered by 10 mm at the front and 15 mm at the rear for improved handling, while the retuned speed-sensitive steering system and solid-mounted front subframe, shared with the standard GTC, benefit steering response.
The wider 9.5J x 20-inch multi-spoke alloy wheels, unique to the GTC Speed, are fitted with bespoke 275/35 ZR20 Pirelli PZero ultra-high performance tyres that provide the car with superior grip as well as sharper steering response and feel.

To ensure optimum aerodynamic balance at speeds up to 200 mph (322 km/h) the new GTC Speed is fitted with a discreet spoiler on the trailing edge of the bootlid. This provides additional downforce and increases the top speed.
For both models, Bentley's carbon-ceramic brakes (CCB) are offered as a cost option. Larger diameter (420 mm front, 356 mm rear), lightweight discs and eight-piston callipers offer fade-resistant braking performance with minimal disc distortion under high thermal conditions. A 20kg weight saving reduces unsprung mass and benefits steering response and handling. This braking system may only be specified with 20-inch diameter wheels and are the largest and most powerful brakes ever fitted to a production car.

The standard-fit tyre-pressure monitoring system (TPMS) allows drivers to select tyre type and speed range parameters. As well as monitoring pressures, the system warns drivers if their speed is too high for the tyre pressures.
Subtle evolution of the GTC's distinctive style
Both the GTC and GTC Speed benefit from subtle revisions to their frontal appearance.
The matrix grille is now more vertical and has a more pronounced square edge that accentuates the distinctive Bentley profile. A new lower bumper design with a widened air intake reinforces the sporting stance of both GTC convertibles, complemented by new chrome headlamp bezels. The new design also provides a practical benefit by improving airflow to the more powerful Speed engine by 14 per cent.
The Bentley Continental GTC Speed has a unique set of design cues, notably a dark-tinted matrix grille to the upper and lower air intakes, a black lower bumper valance, wider, rifled exhaust tailpipes and 20-inch, silver-painted, multi-spoke alloy wheels. The wheels are available as an option with a special dark tint finish.
GTC and GTC Speed customers have a choice of 17 'standard' paint colours including two new colours (Aquamarine and Blue Crystal).

The luxurious hand-crafted cabin
The cabins of both GTC and GTC Speed are available with a choice of 6 natural, unbleached, laser-cut wood veneers and 17 premium grade leather hides, Aquamarine.

The GTC Speed's cabin is based on that of the Mulliner Driving Specification (a cost option on the standard GTC). It features diamond quilted hide seats with embroidered Bentley emblems, a knurled chrome and hide gearlever and a three-spoke multi-function steering wheel with brushed aluminium switch surround. These are complemented by drilled alloy foot-pedals and 'Speed' logos to the polished treadplates. The standard GTC also receives a new Bentley 'B' brake pedal.

New adaptive cruise control system
A sophisticated follow-to-stop, radar-based Adaptive Cruise Control (ACC) system is now available on both GTC and GTC Speed. It uses a long-range radar sensor, mounted in the lower front grille, to monitor the road ahead for other vehicles. When a slower moving vehicle is detected, the system automatically adjusts the throttle or brakes to maintain a 'time gap', as selected by the driver.
