Back in January, we fleshed out the specs on Coventry's latest super sports sedan, the Jaguar XFR. One month later, we gave you a cockpit play-by-play at the XFR's launch in Seville, Spain. Now it's time to get down to the business of Racepaks and VBOXes to answer the question: Just how does Jaguar's bad little kitty measure up at the test track?

Our 2010 XFR shaved three tenths off the official 0-60 claim, even on the dusty tarmac of our El Toro testing facility. The 510-horse Jaguar also displayed more top-end speed than advertised, blitzing through the quarter mile in a mere 12.7 seconds at 114.1 mph. Meeeewow. (Continued)
