New Jaguar XFR-S in Depth, Sports a Tuned 542hp Supercharged V8

We've already had the opportunity to show you what the brand-new Jaguar XFR-S looks like before its world premiere at the Los Angeles Auto Show, so now it's time to tell you what lies under its sported up body.

Billed as an "ultra-high performance" version of the XF series, the XFR-S is the fastest and most powerful production sedan in the history of Jaguar.

It makes use of the same souped-up 5.0-liter supercharged V8 as the XKR-S, producing 40hp and 41 lb-ft more torque than the standard XFR's V8 for a total of 542hp (550PS) and 502 lb-ft (680Nm). An 8-speed Quickshift automatic transmission with steering wheel-mounted paddles drives the rear wheels.

Jaguar quotes a zero to 60 mph acceleration time of 4.4 seconds1 (0-100 km/h in 4.6 seconds) and an electronically-limited top speed of 186 mph1 (300km/h) – an improvement of 0.3 seconds and 31mph (50km/h) respectively over the plain-Jane XFR.
