Red Bull Jerez test summary

Driver:      David Coulthard

Car:         RB4 01

Time:        1:19.494, Laps: 93

Fastest Lap: H. Kovalainen 1:18.385
Circuit length: 4.423 km

1742 kilometres completed in four days and five 18 hour days for our test team, all carried out in boiling hot weather. It has been a tough but very productive time, with the large distances covered showing that reliability was good throughout.

After Sebastien Buemi and Mark Webber, it was David Coulthard's turn to strap himself into the cockpit of RB4 for the final day. While the programme earlier in the week included long term development and assessment of the 2009 slick tyres, DC focused exclusively on the forthcoming races of this season, only running this year's tyres to end up third quickest on the day. The testing ban now comes into force, which means the next outing for the test team takes place at the Monza circuit at the end of August.
