Jaguar caught testing high-performance XFR estate but maintains there are no plans for production

Our spies have spotted what appears to be a Jaguar XFR-S Sportbrake undergoing testing at the brand's facility at the infamous Nurburgring Circuit in Germany. 

The black prototype features lowered suspension and quad-exhuast pipes plus bigger air-intakes, larger alloy wheels and wider brake discs all round - suggesting that the company are definitely exploring the possibility of a high-performance version of its elegant estate car.

Its closest rivals would be the new Audi RS6 Avant and Mercedes E63 AMG Estate so this mule was likely to be powered by a tuned version of the 5.0-litre supercharged V8 engine with well over 500bhp.

However at this stage the company has no plans to put the car into production as customer interest was too low and boss Adrian Hallmark has said previously that: "It would be difficult to re-engineer the suspension [of the Sportbrake] for that type of engine"

Clearly this working mule shows that the conversion is possible and the project could be part of a plan to drum up interest in an 'R' badged version of the estate to help generate demand but at the moment the car remains a side project as Jaguar remains focussed on fettling its mass market small saloon and rival to the BMW 3 Series - which is due to arrive late next year.
