colin mcrae v clarkson v f1 car at silverstone

who is fastest? colin mcrae in a 300 bhp 4wd group A ford focus or Johnny Herbert in a 800 bhp stewert f1 car,maybe its jeremy clarkson in a 170 bhp ford cougar! whatever the outcome its worth watching this to see colin drifting the focus around the silverstone circuit,and johnny herbert’s attacking lap on cold tyres in the wet is also impressive.
