SHANGHAI — Ferrari's Felipe Massa set an ‘incredible' pace to top the timesheets at the end of Chinese Grand Prix practice Friday after Nico Rosberg had led a Mercedes one-two in the morning session. “In terms of everybody else on the tire, the pace is not good, it's incredible,” declared the Brazilian's race engineer Rob Smedley after Massa set a quickest time of one minute 35.340 on the soft Pirelli tire being used for the first time this season. Kimi Raikkonen, winner of Formula One's Melbourne season-opener in March, was second fastest for Lotus in 1:35.492 at the circuit outside Shanghai. “When I fitted the softs, the car improved a lot ... it was impressive, like driving two completely different cars,” said Massa, who has out-qualified teammate Fernando Alonso in the last four races. Last year's winner Rosberg had lapped in 1:36.717 before lunch, with 2008 world champion Lewis Hamilton 0.454 slower. Teams focused largely on longer runs in the afternoon. The German has led the race in Shanghai in the past three editions while his 2012 win at the monumental circuit was the first of his Formula One career. Hamilton, third in Malaysia last month after Rosberg was ordered not to overtake because of concerns the cars might run out of fuel, is the only driver to have won twice in China. Red Bull's Mark Webber, whose working relationship with world champion Sebastian Vettel hit a new low after a team orders storm in Malaysia, ended both sessions ahead of the German. Webber was third and fifth respectively while Vettel was fourth and 10th. “It was a tricky day for us. I seemed to struggle a little bit more this afternoon; the gap to the guys at the top is a bit bigger than I would like,” Vettel said. “But we have two or three things to work on and we should be in better shape Saturday. It's not a disaster.” Alonso lapped fifth in the morning and third in the afternoon, but with a car in a different specification to Massa's, while McLaren's Jenson Button was sixth in both. “We can't yet conclusively tell if the upgrades we brought to this race have improved the car,” Button said. Triple champion Vettel leads the championship after two races with 40 points, nine clear of Raikkonen. China's Ma Qing Hua, in the Caterham that will be raced by Frenchman Charles Pic Sunday, wrote a foootnote in Formula One history by becoming the first Chinese driver to take part in a Grand Prix weekend on Chinese soil. He was last of the 22 drivers on track in the morning, 6.828 seconds slower than Rosberg, with both Caterhams lagging rivals Marussia at the tail end. Button's Mexican teammate Sergio Perez damaged the front wing of his McLaren when he skidded off into the gravel at the pitlane entry at the end of the session. The team said they had plenty of spares. — Reuters
