Designing a convertible combining these levels of performance and refinement brings its own unique challenges. Fortunately, Bentley has an unequalled history when it comes to convertibles, and the GT Speed Convertible is the latest, fastest and most thoughtfully-executed of all. Drive it with the hood down and a new dimension is revealed. Youre no longer an observer of the passing landscape but a part of it, with every aspect of your journey especially the thrilling sound track amplified in the open air. The Speed Convertible is also available with the All Seasons Specification that includes a Wind deflector, Neck warmer and heated leather steering wheel, ensuring that roof-down motoring can be enjoyed all year round and whatever the outside temperature. However, should you choose to close the roof, the levels of refinement, acoustic insulation and cosseting comfort provided are truly exceptional. With peak power of 635 PS, the Continental GT Speed Convertible stands at the pinnacle of the Bentley Continental stable. A full throttle standing start sees 60 mph flash past in just 4.1 seconds, with a top speed of 203 mph. Yet Bentleys engineering team has ensured that the new GT Speed W12 engine and powertrain is just as fuel-efficient as the Continental GT. The latest engine management system, an eight-speed transmission and careful refinement of the turbocharger settings have seen an overall improvement of 12% in fuel economy, with a commensurate increase in tank range compared to the previous generation model. Revised Electronic Stability Programme calibration gives the driver free rein to explore the limits with safety, while the sports chassis tune and lowered suspension accentuates the glued-to-the-road sensation during high speed cornering. Searing power, precise handling yet civilised behaviour in city traffic: a powertrain of supercar performance, in every sense. The Continental GT Speed Convertible features a sport-tuned exhaust, a deep baritone, civilised and refined during high-speed cruising, building to a crescendo - deeper and more exhilarating - under hard acceleration.
