The Jaguar the XKR-S – is now joined by the convertible version that will be unveiled at the Los Angeles Auto Show. The XKR-S gets the same 5.0-litre supercharged AJ-V8 engine, which produces 550bhp of power and 680Nm of torque. These figures represent a power increase of 8 percent and torque increase of 9 percent over the Jaguar XKR. Driving the rear wheels through a six-speed automatic gearbox with Active Differential, this propels the XKR-S Convertible to 100kmph in 4.4 seconds and on to an electronically limited top speed of 300kmph.
