0-186mph in under a minute sounds like supercar territory, but the Jaguar XJR575 will do it with a statesman relaxing in the back of its long-wheelbase body. The 5.0-liter supercharged V8 now generates 575 metric horsepower, with only rear-wheel drive available. A self-shifting 8-speed transmission is the only gearbox available. The XJR575 is fully loaded, with the only optional really being a 360-degree camera and adaptive cruise control. Safety is handled by traffic sign recognition, lane departure warning and optional forward collision avoidance.
