Bourdais impresses in F1 test.

Reigning Champ Car World Series champion Sebastien Bourdais enjoyed a very productive three days of testing at Jerez in Spain this week, giving the assembled F1 team bosses a good look at what they have potentially missed out on.

Just weeks after conceding that his Formula One ambitions were virtually over, Bourdais logged nearly 300 laps of the 4.423km Spanish circuit on Wednesday, Thursday and Friday getting quicker and quicker each time he took to the track in one of the 2006 Scuderia Toro Rosso machines.

Reigning Champ Car World Series champion Sebastien Bourdais enjoyed a very productive three days of testing at Jerez in Spain this week, giving the assembled F1 team bosses a good look at what they have potentially missed out on.

Although this week's test has been viewed as a one-off, the Frenchman will have been pleased to finish the final day just two tenths of a second slower than Ferrari tester Marc Gene and less than two second behind pacesetter Lewis Hamilton's McLaren.

Bourdais' best time of the test came on Friday when he stopped the clocks in an unofficial time of 1min 21.258secs, almost exactly four years to the day since he last sat in an F1 car.

"Luckily, after two days acclimatising himself, Sebastien was up to speed and was able to complete our final day's programme," explained Scuderia Toro Rosso Chief Engineer, Laurent Mekies.

"On the technical front, we were again concentrating on a familiarisation programme with the Bridgestone Potenza tyres. They were the same as those we tried last week. The stable weather meant we were also able to try major changes to car set-up with a view to understanding how these were affected by tyres, while also evaluating new brake materials."
