Jan.16 (GMM) David Coulthard will have the honour of giving Red Bull Racing's new car for 2008, the RB4, its maiden track outing at Jerez on Wednesday.

Mark Webber, the Scot's Australian teammate, will continue driving the team's 2007 car after the launch at Jerez, in the sherry-producing south of Spain.

Elsewhere on Tuesday, on the eastern coast of Spain at the Valencia circuit, Robert Kubica for the first time in his career got the privilege of giving a new formula one car its debut.

Watched on by experienced German teammate Nick Heidfeld, the Pole guided a trouble-free first outing for the newly launched BMW-Sauber F1.08.

"The roll-out went off absolutely hitch-free," said team boss Mario Theissen.

"All systems were functioning from the word go and Robert has gained a positive first impression of the new car's handling," he added.

Back at Jerez, Timo Glock played down the performance of the new Toyota TF108 as he powered it to just eleventh quickest of the thirteen runners.

"My first impression of the car is generally positive but at this stage of the year it is too early to truly know how competitive it will be," the German said.
