Car issue hindered Rosberg’s pace

Mercedes believes a problem with Nico Rosberg's car caused his severe tyre management issues during the Spanish Grand Prix. The German fell from fifth to seventh late on as his tyres wilted and Kamui Kobayashi's Sauber and Sebastian Vettel's Red Bull overtaken him, with McLaren driver Lewis Hamilton doing likewise. Mercedes technical chief Bob Bell, who was heading the team this weekend in the absence of the unwell Ross Brawn, said a potential technical problem cost Rosberg downforce and made it even harder for him to look after the Pirellis.
