With a 325 kph top speed, this car delivers exhilarating performance from an uprated 625 PS (616 bhp) W12 engine and eight-speed transmission.
Crewe, England -- The Continental GT Speed Convertible, Bentley’s new open-top performance flagship - and the world’s fastest four-seat convertible - made its international debut at the North American International Auto Show in Detroit USA.
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 kph) 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.
Bentley Chairman and Chief Executive Dr Wolfgang Schreiber said that 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."
The Continental GT Speed convertible shares its powertrain specification with its Bentley stable mate 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 kph in 4.4 s.) and onto a top speed of 202 mph (325 kph).
Nought to 100 mph (160 kph) 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 CO2 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.
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.
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.
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.
