Earlier this week, we posted a photograph of two McLaren supercars. We mistakenly thought they were the McLaren P1, the car that Microsoft used to promote Forza Motorsport 5 during its E3 press event. They were, in fact, McLaren MP4-12Cs. It was an egregious error, and for that we apologize.

Imagine our surprise, though, when we spotted a genuine McLaren P1 at Microsoft's E3 booth today. To make up for our mistake, we took lots of pictures and a nice video. We showed it to Jordan Mallory, Joystiq's senior car enthusiast, and this time he died. Just straight-up died.
