**Please note, the final car bodywork is being kept secret by Jaguar**
Just as Jaguar unveiled its Advanced Lightweight Coupe concept in Detroit, our spy photographers caught the real thing out testing. On the road, it looks more like an XK replacement than the show car, with a similar profile and stance in that context. It's a relatively conservative but good-looking 2+2, built on a version of the lightweight aluminium architecture used for the current XJ saloon. Designed under the leadership of Ian Callum, the taut, simply-styled body has little adornment and no superfluous detailing; the disguises hide gill-like side air vents and the angular headlights seen on the ALC show car. Under that bonnet is a V8 said to be good for 180 mph and 0-60 in less than five seconds, pitching the car nearer to the likes of the Porsche 911 and upcoming Aston V8 Vantage than the current XK.
