A Jaguar XFR Sportbrake has been investigated, but the cost of re-engineering the Jaguar XF Sportbrake’s underpinnings make it tricky to justify.

Jaguar’s global brand director, Adrian Hallmark, said such a car would be an “interesting project”, and a useful halo model for the resurgent brand. But he said installing the 503bhp 5.0-litre supercharged V8 would be complex.

“It would be tricky to re-engineer the self-levelling rear suspension to cope with the high performance of such an engine”, said Hallmark. But be admitted it would be “interesting” to build a limited run of 300 to 400 units.
