The British automaker has confirmed that the XJR will be kicking out a full 550-horsepower and 680 Nm of torque from its supercharged 5.0-liter V8, affording the sedan a 0-60 mile per hour sprint of 4.4 seconds and a top speed of 280 Km/h. A ZF eight-speed automatic transmission will still allow for respectable fuel economy, as Jag estimates ratings of 15 miles per gallon city and 23 highway.
Newly tuned dampers and stiffer spring rates, along with an electronically controlled differential should ensure that the massive power of the engine isn't wasted in transition to the road. Jaguar has also tweaked steering software and hydraulics, with the goal of increased road feel, response and overall feedback. 20-inch signature wheels carry wide Pirelli rubber (265-section up front, 295 in back) to keep the XJR planted.
