Williams, Jaguar to build supercarWilliams has teamed up with Jaguar to assist in the production version of its C-X75 hybrid supercar, the two companies announced at the Turkish Grand Prix.

The Jaguar C-X75 will become the Jaguar marque's "most advanced model to date," delivering CO2 emissions of less than 99g/km while being able to achieve in excess of 200mph. The initial concept design study made its debut at the 2010 Paris motor show. The car will be homologated for road use.

"People expect Jaguar to be innovators – that is when Jaguar is at its best," said Adrian Hallmark, Jaguar brand director. "The C-X75 received an incredible reception as a concept car. We've been building on that momentum and there is a clear business case for this exclusive halo model. No other vehicle will better signify Jaguar's renewed confidence and excellence in technological innovation than this."

Williams will be providing engineering expertise in areas including aerodynamics, carbon composite manufacture and hybrid technologies.

"Our new association with Jaguar Land Rover provides us with an exciting opportunity to work with one of the motoring world's most famous and iconic brands," said Frank Williams. "Williams has always considered itself an engineering company and so this project will allow us to combine our technical expertise to create something truly exceptional."
