McLaren driver Jenson Button topped the timesheets on the first day of testing in Jerez, eight tenths of a second faster than second place Mark Webber. It wasn’t all glory for McLaren, as Button was forced to sit out half the day due to a fuel-pump problem, but when they were up and running the team said the balance and aero on the car was exactly as they’d anticipated.

Behind the top two came Romain Grosjean followed by Paul Di Resta. Further down the order, Giedo van der Garde made his debut for the Caterham team as an official driver, finishing tenth, only ahead of Max Chilton. The Marussia driver crashed due to a suspension problem, cutting short the team’s running, a disappointing end to their launch day.

Mercedes also had to halt their running early, after Nico Rosberg completed only 11 laps. The car stopped out on track due to a fault with the wiring loom, bringing out a red flag, and the team confirmed they would not run for the rest of the day, hoping to modify the parts in time for tomorrow’s action.
