It will be powered by a 550bhp V8 engine which some sources say will be built by Mahle (which bought out the old Cosworth business) in Northamptonshire. It’s thought that the McLaren engine will be based on an existing Mercedes unit.
The Spider version will follow in March 2011, while the top version, codenamed P12 will debut in summer of 2011. It will be powered by a V10 engine delivering over 600bhp and will cost around £250,000.
