Around this time last year we brought you spy shots of a high-performance version of the XF sedan that Jaguar
has been developing. Now reports from the UK indicate that the 542-horsepower XFR-S could be ready as early as November. With an eye on the 552hp BMW
M5 and 549hp Mercedes-Benz
E63 AMG, the Jaguar XFR
-S is expected to pick up where the (relatively) "underpowered" 503hp XFR leaves off by incorporating the supercharged V8 engine from the XKR-S super-coupe.
