The new Jaguar F-Pace is only now hitting dealerships, but the British automaker is already testing a bigger, higher-end example. Allegedly named J-Pace – tying it to the flagship XJ sedan the same way the F-Pace is to the XF (so expect an E-Pace before too long) – Jaguar's engineers stretched the wheelbase and cobbled together a big CUV from an F-Pace's body parts.

The biggest giveaway is on the rear door's cutline. A normal F-Pace's shut line runs right into the middle of the rear wheel arch. But on this mule, the door closes well forward of the arch. Outside the axles, Jag has stretched the front overhang – it's far more prominent with a completely different lower intake – and the super-short rear overhang reinforces the idea that we're seeing a longer platform.
