New McLaren P11

McLaren is already testing their second supercar - the P11, a new model that will compete with Ferrari F430, but the P11 will be noticeably lighter and more compact than the competition. It will make its official debut in autumn 2009, and sales will begin in March 2010. The P11 will be followed by both open-top and hardcore versions of the base model.

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.
