The Continental GT Speed Convertible, Bentley’s new open-top
performance flagship - and the world’s fastest four-seat convertible -
makes its international debut on 14
th January at the North American International Auto Show, Detroit.
The new GT Speed Convertible combines the sensory pleasures of
roof-down luxury touring with the shattering performance of a 625 PS
(616 bhp) twin-turbocharged 6.0 litre W12, while delivering a fifteen
per cent improvement in fuel efficiency. The close-ratio eight-speed
transmission, uprated and lowered suspension and retuned steering
provide exhilarating acceleration and sharp, communicative handling
without detriment to the renowned ride comfort of Bentley’s Continental
convertible. Permanent all-wheel drive ensures optimum traction and
power delivery whatever the road conditions.
Taking its place at the pinnacle of the Bentley Continental range, the
new GT Speed Convertible has a top speed of 202 mph (325 km/h) and in
true Bentley style, no compromises have been made in craftsmanship,
luxury or refinement to deliver this unrivalled performance.
Subtle sporting design cues include exclusive 21-inch alloy wheels,
dark-tint grilles and ‘rifled’ exhaust tail pipes. Inside its
handcrafted cabin, the GT Speed convertible features the Mulliner
Driving Specification as standard, blending contemporary luxury with a
distinctly sporting character.
Commenting on the new Continental GT Speed Convertible, Bentley
Chairman and Chief Executive Dr Wolfgang Schreiber said: "Following the
recent successful introduction of the GT Speed, the new GT Speed
Convertible will appeal to drivers who seek the sensory thrills of the
world’s fastest four-seat soft-top and the practicality of a year-round
grand tourer, together with unrivalled levels of luxury and refinement.
It is designed for those who accept no compromise."
Powertrain: 12 cylinders, 625 PS (616 bhp) and 8 gears
The Continental GT Speed convertible shares its powertrain
specification with its Bentley stablemate the GT Speed coupé. The 625 PS
(616 bhp) twin-turbocharged, 48-valve, W12 engine powers the new
convertible to 60 mph in 4.1 seconds (0-100 km/h in 4.4 s.) and onto a
top speed of 202 mph (325 km/h). Nought to 100 mph (160 km/h) is
despatched in only 9.7 seconds. Peak torque – an impressive 800 Nm (590
lb.ft) – is reached at just 2000 revs/min and maintains that level
through to 5000 revs/min for effortless, refined performance at all
times.
The latest ME17 engine management system, capable of performing 180
million individual calculations per second, provides enhanced
turbocharger control and torque management, enhancing driveability. In
common with all W12-engined models, the GT Speed convertible features an
energy recuperation system. Together with a close-ratio, quick-shifting
eight-speed transmission, this has resulted in a 15 per cent
improvement in fuel economy and CO
2 emissions compared with the first generation Speed, with a commensurate increase in tank range.
The new GT Speed Convertible’s powertrain is even more tractable than
its Speed predecessor, and just as fuel-efficient as the new W12
Continental GT. Switching the gear selector to ‘Sport’ mode however
demonstrates the dual personality of the new GT Speed convertible,
delivering a sharper throttle response, gear-shifting at higher engine
speeds and faster ‘block shifting’ (eg 8th direct to 4th gear) for
instantly accessible acceleration. The enhanced performance is
accentuated by a glorious baritone snarl from the free-breathing
exhaust, a thrilling soundtrack to the magnificent powerhouse under the
bonnet.
Chassis; lower, sharper and more involving
With torsional stiffness a class-leading 22,500 Nm/degree, the
bodyshell of the Continental GT Speed convertible is exceptionally
rigid, laying the perfect foundation for a more engaging driving
experience. The aluminium double-wishbone front suspension and
trapezoidal multi-link rear setup feature revised air suspension springs
and dampers for improved agility and body control with little sacrifice
in ride comfort.
The self-levelling system is set 10 mm lower than the 575PS Continental
GT convertible. Stiffer suspension bushes ensure sharp, communicative
handling, while uprated anti-roll bars optimise the handling balance.
The result is improved body control under hard cornering together with
greater agility and, because steering plays an essential role in feeding
response and grip back to the driver, the Servotronic steering has also
been recalibrated for the Speed specification.
The Electronic Stability Control (ESC) system is optimised for the new
engine management system to deliver both outstanding safety and greater
driver involvement. The ESC system retains the “Dynamic Mode” setting
that allows increased wheel slip at higher speeds, with engine torque
reinstated more quickly after a system intervention. Together, these
systems give the keen driver more opportunity to exploit the full
potential of the new chassis set-up and higher power output.
Exterior – the darker side of Bentley design
From outside, the Continental GT Speed convertible is distinguished by a
matrix radiator grille and bumper air intakes in a dark-tint chrome
finish. The 21” Speed alloy wheels are unique to this model, and are
available in silver or an optional dark tint. Large, elliptical exhaust
tailpipes feature a rifled interior, while a further, subtle design
touch is revealed when the bonnet is opened – the black inlet manifold
is unique to the Continental Speed models. As with the GT Speed coupé,
the winged ‘B’ badge which crowns the radiator shell is set upon a black
enamel background.
The front wings of the GT Speed Convertible are created in superformed
aluminium, their seamless form and crisply-defined body creases creating
an impression of tension and muscularity. The 10 mm lower suspension
and unique 21” wheels accentuate the wide, low and poised stance.
Despite the supercar performance, additional spoilers are unnecessary –
the gentle lip on the double-horseshoe bootlid generates all the
downforce the GT Speed Convertible needs, even at over 200 mph (325
km/h).
Interior: sumptuous, exclusive luxury and advanced technology
Inside, exclusive treadplates featuring the ‘Speed’ legend welcome you
to a four-seat cabin that features the hand-craftsmanship of the
Mulliner Driving Specification, with its distinctive diamond-quilted
hide upholstery. For the Continental GT Speed models Bentley offers an
exclusive Dark Tint Aluminium ‘engine spin’ finish, inspired by the
dashboards of the Le Mans winning Bentleys of the 1920s. Its understated
shade is the perfect complement to the exterior’s dark tint chrome
radiator and bumper grilles. Other optional finishes include the full
range of fine wood veneers and a satin-finish Carbon Fibre option for
fascia and centre console.
The infotainment system features Bentley’s latest software upgrades,
which vary from region to region but include refinements such as point
of interest mapping, optional satellite landscape imagery, live traffic
data and, where the infrastructure supports it, digital radio. The
system features 15 Gigabytes of available music space, as well as the
facility to play music via an iPod, MP3 player, the car’s own six-disc
CD changer or SD card.
Flat panel Balanced Mode Radiator (BMR) speakers, which combine the
functions of separate tweeter and midrange speakers in one unit, direct
the sound with accuracy and provide greater clarity across the audible
spectrum. Alternatively, the audiophile Naim for Bentley system,
incorporating custom-built speakers and eight individual Digital Sound
Processing modes, is available as an option. As a thoughtful touch, the
audio balance settings automatically alter when the roof is lowered to
compensate for the change in listening environment.
The thrill of the open road, 365 days a year
The new Continental GT Speed Convertible offers the luxury and
refinement of a coupé yet transforms into a head-turning open tourer at
the touch of a button. The four-layer hood ensures high levels of
refinement and acoustic insulation. Exhaustively tested in all
conditions from -30°C to +50°C or more, it resists even monsoon-force
rain and maintains comfortable, draft-free warmth even on the coldest
days.
Another practical feature, the neck warmer, makes open air driving an
appealing and comfortable prospect even on the cooler days of spring and
autumn. With the hood down, the Continental GT Speed convertible offers
sensational performance with the sensory amplification of open-air
motoring. Hood up, it’s as practical a year-round proposition as its
coupé stablemate.
As with every Bentley Continental model, the GT Speed convertible
offers the reassuring stability of permanent all-wheel drive, biased
60:40 in favour of the rear so the spirited driver can control the car’s
line with the throttle. The rear-biased torque split also minimises
understeer during hard cornering while the system varies torque between
the front and rear axles for optimum grip in all road and weather
conditions.
The result is an exhilarating combination of performance and
practicality; a Bentley that can tackle sun-drenched boulevard or snowy
alpine pass with equal aplomb.
