Both body styles are reportedly built on a carbon fiber tub with aluminum front and rear subframes. Weight is expected to be less than 3,000 pounds, making it one of the lightest high-performance cars on the road (the current Mercedes-Benz SLR McLaren coupe, more than a bit on the porky side, tips the scales about 750 pounds heavier). Power for the supercar is expected to come from a 550-hp V8 built by famed engine builder Mahle.
Now that the design of the P11 is theoretically set in stone, McLaren needs to find a factory in which to build it. Sites across Europe, including those in Italy, Austria, and Britain, are being considered. Insiders say the factory will announce their manufacturing decision next summer.
