Bentley made the Continental GT Speed Convertible official today. As well as the engine upgrades we speculated about, it also gets the close-ratio eight-speed transmission, uprated and lowered suspension and retuned steering. Essentially its the same car as the GT Speed, except the roof has been removed!
Bentley are marketing the Bentley Continental GT Speed Convertible as the fastest four seat convertible, and rightly so. It features a twin-turbocharged 6.0 liter W12 with 625hp produced at 6,000rpm and 800Nm of torque. That is enough for a 0-100km/h of 4.4 seconds, to 60mph, the Bentley is 0.3 seconds faster.
The ZF eight-speed automatic transmission has intelligent adaptive control software for smoother changes and a fifteen percent increase in economy and CO2 emissions.
Torsional stiffness of the chassis is an impressive 22,500 Nm/degree. Suspension is an aluminium double-wishbone at the front and trapezoidal multi-link rear setup with revised air suspension springs and dampers. The ride is 10mm lower all round with a stiffer setup.
The body changes include a large, elliptical exhaust tailpipes, a matrix radiator grille and bumper air intakes in a dark-tint chrome finish. The wheels are 21 inch Speed alloy wheels with ventilated brake discs measuring 405mm at the front and 355mm at the back.
Inside, Mulliner Driving Specification comes as standard as well as a number of signature Speed design cues that combine contemporary luxury with a distinctly sporting character. The latest infotainment system is also a highlight for the GT Speed Convertible.
