Sakhir, 19 March –The tenth edition of the Bahrain Grand Prix weekend started off with a one-two for Ferrari. After winning in Shanghai, Fernando Alonso set the second fastest time of 1.34.564 in the first free practice session, behind his team-mate Felipe Massa, fastest in the other F138 in a time of 1.34.487. Third, at this the fourth round of the season was the Mercedes of Nico Rosberg (1.34.621.) Both Ferrari men used just one set of Hard tyres each, for their two runs on the dusty Bahraini track. The Scuderia worked on the usual programme of acquiring data, paying particular attention to the aerodynamic behaviour of the car, looking at new parts introduced here and re-evaluating some that were already tried out last weekend in China.
