Next McLaren supercar will not get Mercedes engine

The current partnership between Mercedes and McLaren on the SLR has come to an end, and like all ugly divorces, things are getting a little tense. The next McLaren supercar (internally know as the P11) will not receive a Mercedes engine. Mercedes, who owns a piece of the supercar firm is upset at the thought of supporting a car with a rival’s engine. Now Mercedes is threatening to cease its financial backing of McLaren, according to a report by Germany’s Auto Motor und Sport.

Initial rumors said the future McLaren supercar will be powered by a 6.3-liter V8 making 550 hp, but now, if another supplier will not be found soon the car could see some significant delays.
