Lewis Hamilton continues to set the pace at Hockenheim, on a day which was overcast with a few drops of rain in the morning, cloudy with bursts of sunshine in the afternoon.

In its quest to close the gap in the Constructors' Championship, and to assist Lewis Hamilton and Heikki Kovalainen in the Drivers' Championship, the Woking teams continues to evaluate new aero devices. While the engine cover dorsal fin was not used today, Hamilton did spent the morning trying a new front wing. The Englishman also spent times on set-ups on his way to posting a best time of 1:14.872, over 06.s up on yesterday's best. Tomorrow, Heikki Kovalainen is in action for the Woking team.

As Williams announces that it is to concentrate on its 2008 car in an effort to turn around the recent lack of form, the Grove outfit will take comfort from the fact that Nico Rosberg was second quickest here today. Although the German was 0.385s off Hamilton's pace, he completed more laps (117) than any other driver.

Kimi Raikkonen on duty again for Ferrari, the World Champion continuing with work on finding the best set-up for the F2008, as well as development of various aerodynamic and mechanical solutions.

"I am reasonably satisfied with the way things went during these two days," said the Finn at the end of today's programme. "We mainly tried to find settings for the car which will allow us to be in good shape for the Grand Prix.

"I think we will be competitive on this track, as indeed we have been for the year so far," he added. "The speed isn't lacking, but sometimes, we haven't managed to put together all the elements and have not succeeded in exploiting all the potential at our disposal."

Tomorrow, Felipe Massa is in action for the Italian team, while Raikkonen will be in Brussels, taking part in the European Youth Conference on Road Safety, which takes place at the headquarters of the European Commission at the Berlaymont Building.

It was a case of one car and two drivers today for Red Bull, as David Coulthard ran for the first three hours up to the lunch break, after which Mark Webber took over cockpit duties. The Scot concentrated on race preparation for the German Grand Prix, evaluating the two types of dry weather tyre that will be available, while his Australian teammate focused more on long term work on mechanical development items, as well as completing a couple of aero tests. Webber also did a tyre comparison on long runs.

"It was a productive day which produced some unexpected and interesting results," said the Australian, who will continue here tomorrow, the final day of the test.

It was another good day for Force India as Adrian Sutil remained on duty. The German, who was fourth quickest on Tuesday, continued to make progress, with his best lap being the 5th quickest of the day, just 1.073s off Hamilton's pace.

Sutil was able to complete 97 laps as he worked through a programme of suspension, set-up and tyre comparison work. A technical problem late morning proved to be the only major issue of the day, allowing the team to finish its scheduled plan. Giancarlo Fisichella will take over for the final day of the test tomorrow.
