Aside from the notable exceptions of Juan Pablo Montoya and Kimi Raikkonen, there's not a great deal of crossover between the All-American, ever-so-slightly-yeehah world of NASCAR and the super-serious technology-driven world of F1.
But the gulf between the two motorsports was crossed the other day as 2008 F1 champion Lewis Hamilton swapped 'rides' with double NASCAR Sprint Cup Series Champion Tony Stewart at the historic Watkins Glen circuit in New York state (which, unusually, has hosted both F1 and NASCAR races).
Well, we say swapped rides, but McLaren didn't exactly ship over their latest offering (that would count as 'testing' and thus not be allowed). Instead, Stewart got a go in the 2008 MP4-23. Tight gits. But then that was a championship-winning car, so we doubt he minded too much...
The event was masterminded by Mobil 1, who describe themselves as a 'shared lubricant technology partner' (which sounds vaguely unpleasant to us), and you can see how the chaps got on in the videos below...
