One-third of American Top Gear, Tanner Foust, spent a day in the Lamborghini Reventon, and here's his verdict: "Thumbs up big girl!" The fractional bit of additional horsepower didn't mean much to him, but he did say the brakes were more capable, and, surprise, the car is quite wide and people like to stare at it. After six hours on Italy's B-roads, that basically sums up his impressions. Since he didn't have too much to say in print, we really do hope he's saving the zingers for the show...

The McLaren P11 will still be powered by a 6.2-liter Mercedes AMG unit, but nobody knows yet what the car that goes around the engine is going to look like. Frank Stephenson, recently of Fiat fame, has been given instructions to completely redesign the car when he starts at McLaren. However, he can't take up the position at McLaren until he finishes his "gardening leave," a mandatory vacation between sensitive jobs that aims to prevent employees from taking their inside knowledge with them.

McLaren says that the car won't look anything like the sketches that made the rounds last year. That's not such a bad thing -- while a good looking car, the sketches were uninspiring and a bit derivative. We expect that the man who has had a hand in everything from the BMW X5 and MINI to the Ferrari F430, Maserati Quattroporte and MC12 probably has a few good ideas left lying around. Unfortunately, the arrival of the P11 has been pushed back a year due to the redesign, to probably mid-to-late 2010.
