2016 XP-CR1 IRL

Price: £210,000 Mileage: n/a

This unique XP-CR1 IRL Sports Prototype is based around the Aquila CR1 concept but features a powerful ex-Indy Car IRL V8 racing engine delivering over 600 HP at the rear wheels.

The car has been equipped with the latest in race proven engine, gearbox and power management systems.

Highly competitive and cost effective to operate the XP-CR1 IRL can be used in the BRITCAR Dunlop Prototype or other similar series. Alternatively it would be the ultimate track day car! Developed by SSE-4 Engineering in Australia to meet FIA safety standards, prepared by Advanced Motorsport & Engineering in the UK and supplied freshly prepared with an extensive equipment and spares package, the car is ready to race.

With a staggering 630bhp at 11,500RPM (detuned to around 603bhp as measured at the rear wheels at 10,000 RPM for extended serviceability) and weighing only 900KG and with over 900KG of downforce at 150mph the car is stunningly quick.
