Just a couple weeks ago we brought you the first set of spy shots of the upcoming Jaguar XE two-seater. And now, some new photos show a prototype mule undergoing continued testing on a shortened chassis that's based on the next generation XK. The upcoming mid-engine 911-fighter will be offered as both a coupe and cabriolet and is also expected to be offered with a V6 engine in at least two different configurations: one naturally-aspirated and one supercharged.

Output levels will be competitive with both the 911 and Cayman. These pictures show the cabriolet but very little of the car's final design. For now, Jaguar is using the body of the current XK on its test mules, wisely keeping the design a closely guarded secret. While it won't be ready in time for Frankfurt this September, there's a chance we'll see the XE's official debut next March at the 2012 Geneva Motor Show.
