McLaren has officially nixed the notion of using Honda as an engine supplier for the upcoming P13. Rumors began kicking up earlier in the week that pointed to the two automakers joining forces for the new McLaren 911 Turbo fighter.

While speaking with Autocar, an unnamed source said that at the moment, there's no connection between the deal that will see Honda supply McLaren with Formula One engines and the forthcoming coupe. The source went on to say that Honda won't have any involvement with the P13.

So, what's likely to power the newest addition to the McLaren stable? Good money rests on P13 getting around with a detuned version of the 3.8-liter V8 currently found in the MP4-12C. If that turns out to be the case, buyers can expect to have around 450 horsepower at their command. We can imagine worse ways to travel.
