Mercedes-Benz engines continue to lead the way in the testing in Bahrain, with the fastest time of the third day of testing going to Lewis Hamilton, who completed 67 laps with a best of 1m34.263s. He was seven-tenths up on McLaren’s Jenson Button, but the latter completed 103 laps, for a best of 1m34.976s. He was only just quicker than Felipe Massa’s Williams, which completed 60 laps, with a best of 1m37.066s. The Sauber-Ferrari was the next best with Esteban Gutierrez doing 96 laps and setting a best of 1m37.180s, two tenths up on Sergio Perez’s Force India which did 57 laps for a best of 1m37.367s. Ferrari lost some time with a data collection problem which required a rebooting of the system but Kimi Raikkonen managed 44 laps with a best of 1m37.467s. Daniil Kvyat was the fastest of the Renault-engined cars in his Toro Rosso, with a 1m38.974s, after 57 laps. Pastor Maldonado was next up in his Lotus, but he did only 26 laps for a best of 1m39.642s, while Dan Ricciardo managed 28 laps in the Red Bull but his 1m40.781s was none too impressive. Marcus Ericsson ran 98 laps for Caterham, setting a best of 1m42.130s, while Marussia continued to have a miserable time with Max Chilton doing just four laps. Williams’s Valtteri Bottas was also out running for 55 laps, but the objective was doing pitstops and so he did not set a lap time.
