In one of those ultimately meaningless but still awesome events, Mclaren ran their F1 car on the famed Bathurst/Mt. Panorama track today.
What makes this cool is it gives a tangible measure of a Formula 1 cars performance: presumably driving well within himself, Jenson Button pulled off an unofficial 1:48 sec lap. Compare that with the already blistering fast qualifying times for the V8 Supercars driving 11/10th and tuned specifically for the track, they group about the 2:07 mark. Now that's impressive.
I'm sure a nice polished video will be released soon, in the meantime, youtube offers some fan clips (after the jump) and a news report
