Speed For Bentley Continental GTC
11th January, 2009
- The new GTC Speed builds on the success of Continental GTC
- The 200 mph GTC Speed is Bentley’s most powerful convertible ever
- The latest GTC range is refined and extended with two new models
- The new GTC delivers enhanced style, comfort and choice
Since its debut in 2006, the Continental GTC has enjoyed sales success in over 50 countries across the globe,
attracting younger buyers to the Bentley marque. Customers are attracted to its sleek design, interior
craftsmanship, refined performance and agile handling.
Now, the introduction of the new 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 600 bhp (610 PS) GTC Speed model. It is Bentley’s most
powerful convertible ever and inspired by Bentley’s legendary ‘Speed Models’ from the 1920s.
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.
For the standard GTC, new low-friction dampers provide improved ride comfort. In addition, two significant new
options may be specified on both GTC models: lightweight, fade-resistant, carbon-ceramic brakes, the largest
production passenger car brakes in the world, and a sophisticated follow-to-stop Adaptive Cruise Control system
with long-range radar sensor that monitors traffic ahead and manages throttle and brakes to maintain a
driver-selected time gap.
The GTC’s chassis and exceptionally rigid steel body have proved more than capable of coping with the power of
the 552 bhp (560 PS) 6-litre W12 engine. For the new Continental GTC Speed, Bentley’s twin-turbocharged W12 now
develops 600 bhp (610PS) that delivers true 322 km/h (200 mph) performance, with the roof up, with exhilarating,
effortless acceleration. Even with the roof down the GTC Speed can reach 312 km/h (195 mph).
The 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 600 bhp (610 PS) 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 (553 lb ft). This is achieved across virtually the complete rev range, from just 1,700 to 5,600
rev/min, delivering that characteristic Bentley wave of torque.
The 0-100 km/h sprint is despatched in a mere 4.8 seconds (0-60 mph in 4.5 seconds) and 0-160 km/h in 10.5
seconds (0-100 mph in 10.6 seconds).
The GT Speed coupe, which debuted in 2007, has become the top selling GT model across the globe. This was
followed in northern summer 2008 by the 4-door Continental Flying Spur Speed. Now, the Speed family is completed
with the introduction of the GTC Speed, which is expected to account for up to two-thirds of GTC sales worldwide
in its first year of production.
Bentley Chairman and Chief Executive, Dr Franz-Josef Paefgen explains the rationale behind the GTC Speed: “The
Continental GTC is an elegant Grand Touring convertible in the Bentley tradition, exciting the emotions with its
distinctive blend of performance, luxury, craftsmanship and modernity. The GTC Speed completes the family of
Continental Speed models and broadens the appeal of the GTC to customers who demand a more focused, open-top
driving experience.”

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 new 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 GTC.
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 5,600 rev/min. The GTC Speed engine is visually differentiated by the
‘crackle black’ finish to the intake manifold.
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 weather
conditions. 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.
Brian Gush, Director, Chassis and Powertrain Engineering, comments: “The new GTC Speed exemplifies our passion
for creating cars that deliver exceptional performance and driving enjoyment. It is a driver’s car which will
redefine people’s expectations of what a luxury convertible can achieve.”
A luxury convertible with outstanding ride and handling
The Continental GTC’s steel body has an exceptionally rigid torsional stiffness of around 30 Hz 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 552 bhp (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 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 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 extra cost option. Larger diameter (420
mm front, 356 mm rear), light weight discs and eight-piston callipers offer fade-resistant braking performance with
minimal disc distortion under high thermal conditions. A 20 kg 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 or if tyre speed ratings are exceeded on winter tyres.
Commenting on the GTC Speed’s character, Dr. Ulrich Eichhorn, Member of the Board, Engineering, said: “The GTC
Speed offers super car performance, superb refinement, comfort and unrivalled craftsmanship all in one car. It
perfectly evokes the spirit of the original Bentley ‘Speed Model’ of the 1920s.”
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 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).
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, including the new option, Aquamarine.
The GTC Speed’s cabin is based on that of the Mulliner Driving Specification (an extra 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.
A range of options give further opportunities for personalisation, including fascia panels, centre console, door
pads and rear quarters in bright aluminium. Uniquely, the GTC Speed is also available with a dark tint aluminium
option.
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.
