The latest Experimental Prototype (XP) 12Cs are lapping it up at number of test locations around the world, including Spain’s Applus IDIADA facility, one of the most comprehensive independent proving grounds in Europe.

The video features XP8 and XP10, two XP Beta-phase prototypes, wrapped almost entirely in matt black vinyl.

The XP Beta test cars feature significant technological advancements taking the 12C nearer to production.

A revised version of the M838T twin-turbo engine, transmission featuring new gear ratios, a more efficient cooling package, new suspension geometry and upgraded electrical architecture are the headline features of current prototypes.

McLaren Automotive program director, Mark Vinnels, is leading the engineering team and said indicative performance figures generated by the XP Beta cars are expected to be announced in March.

“There is an extensive list of subjective and objective targets set for our prototype vehicles. These XP Beta cars are already achieving outstanding results in many of the subjective areas, which includes ride quality, handling and many other aspects of dynamic performance.“Between now and production the vehicles and the team are working flat out. All this is geared towards not just achieving our unprecedented levels of performance but also guaranteeing the levels of quality, reliability and durability with which we expect to delight future McLaren customers.”
