Until today it's been known as the P11. Now, we've got the first official photographs of what we told you earlier is now called the McLaren MP4-12C β€” the first bespoke McLaren road car since the F1. Gallery below.

So let's answer the real question everyone's got β€” what's under the hood. Here's what we're told:

"It's a 3.8-litre 90-degree V8 mounted amidships and producing β€˜around 600bhp and 443lb ft'. β€˜It delivers the highest horsepower to CO2 ratio of any car on the market today with an internal combustion engines – and that includes petrol and diesel hybrids,' boasts Antony Sheriff, MD of McLaren Automotive. Expect a CO2 output somewhere just south of 300g/km.

Contrary to earlier speculation, this is McLaren's own V8, dubbed M838T and breathed on by twin turbos and driving the rear wheels through a seven-speed dual-clutch gearbox (no manual is available). The V8 has a dry sump and a flat-plane crank like a race engine, to lower the centre of gravity and allow a higher rev limit of 8500rpm.

Every single component of the MP4-12C is unique, vows McLaren. Not a single switch or part is pilfered from a rival's parts bin.


What about the 0-to-60 time? McLaren folks claim it'll be in "the three-point-something-second" range with a top speed over 200 MPH. Nice.
