Driver:       David CoulthardCar:          RB4 - 01Time:         1:19.494, Laps: 93Fastest 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,  onlyrunning 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 atthe Monza circuit at the end of August.
