Pigeonholing the XKR is no easy task. On one end of its competition spectrum is the Porsche 911, a true sports car that can run rings around the XKR on the track or a twisty mountain road, but doesn’t offer the on-road comfort or luxurious interior of the Jaguar. On the other end are cars like the BMW 650i – or the M6 if you want to stretch it – which doesn’t have nearly the visual appeal of the XKR. For more money there’s the Aston Martin V8 Vantage coupe, the Mercedes-Benz CL or the Maserati Gran Turismo.
