The co-driver is a Spanish F1 commentator who follows Alonso everywhere. He says that the SLR weights less than 600 kg and that it accelerates from 0 to 100 Km/h in 3 seconds
This is a much better video than the last one posted. More shots forward on the track and the steering action. Always nice to see an F1 driver bully his way thru a road car.
I actually saw another silver SLR on the way into work today. Although we were in morning traffic, I still have yet to see (in person) an SLR driver even lean on the throttle yet Supercars and auto trans ---> posers!
