Underneath this prototype's ill-fitting XF bodywork are the underpinnings of the Jaguar XS - the British luxury brand's upcoming competitor for Germany's popular compact sedans.

The Jaguar XS name isn't confirmed yet for a model that isn't expected until about 2015 and is currently being developed under the codename X760 as a rival for the likes of the Audi A4, BMW 3 Series and Mercedes-Benz C-Class.

It will mark a return to entry-level luxury for Jaguar since the X-Type was discontinued in 2009.

Signs that this is no ordinary version of the mid-sized Jaguar XF are the ill-fitting doorhandles and the noticeable wheel arch overlaps that reveal narrower tracks (axle widths) front and rear.

Jaguar's design director, Ian Callum, told CarAdvice last year that the company was investigating smaller models, though added that it couldn't just create a conventional-looking four-door sedan.

Expect a more coupe-like approach to the four-door Jaguar XS, with Sportbrake (wagon) and crossover variants likely.

A Jaguar XS R performance version would give the brand a rival to the Audi RS4, BMW M3 and Mercedes C63 AMG.

Drivetrains would undoubtedly comprise Jaguar's four-cylinder turbo and supercharged V6 petrol engines, as well as turbo diesel offerings.
