The new Mercedes W03 F1 successfully completed its rollout at Silverstone on Thursday. The permissible 100km stint on demonstration tyres was shared by the two first-choice drivers, Nico Rosberg and Michael Schumacher.

"It's very difficult to assess performance on rollout because we have to fit demonstration tyres and we're only allowed to use the short track configuration, but the car behaved as expected," said Haug. "There were no teething problems."
