De la Rosa fastest at Jerez

The Spaniard's best time was 1:19.109, over three tenths of a second ahead of runner-up Jarno Trulli for Toyota, who in turn pipped Honda's James Rossiter by just over a tenth of a second.

The second day of the official testing session saw all teams but Spyker continue their adjustment work with the new Bridgestone tyres, with most teams putting emphasis on long runs.

Under sunny sky, and with ambient temperature of 20C degrees, the teams enjoyed a relatively trouble-free day, although there were a few red flag incidents throughout the morning and afternoon sessions.

First to bring proceedings to a halt was Renault's Giancarlo Fisichella, who stopped on track as early as 9:30am. An hour later, McLaren's Lewis Hamilton did the same, while Red Bull's Michael Ammermuller brought out the red flags by lunchtime, with a harmless off-track excursion.

A more serious-looking incident took place at 3:20pm, when Scott Speed lost control of his Toro Rosso-Cosworth at the Curva Sito Pons, crashing heavily and bringing out the red flags. The American was unharmed, and the cause for the crash was pinned down to brake failure.

Other red flag incidents took place in the afternoon when Williams's Kazuki Nakajima had a harmless off-track excursion, and when Trulli stopped on track just moments before the testing day had ended.

Champ Car champion Sebastien Bourdais enjoyed a productive second day of testing for Toro Rosso, the Frenchman wrapping up 78 laps with a best time of 1:21.539 - a second faster than his best yesterday, and just 0.025 seconds slower than teammate Tonio Liuzzi.

The day was also remarkable for Toyota's veteran test driver Olivier Panis, who is retiring altogether from Formula One after this final test.
