Lewis Hamilton has won the Grand Prix of Bahrain, fending off an exciting challenge from team mate Nico Rosberg who started from pole. Sergio Perez was overjoyed with finished third as the Mexican completes the podium.
What I found interesting during Nico's pole lap commentary with him on Sky was that he said that he had actually lost hybrid power in one of the corners later in the lap. I think it shows that all PU systems have a long way to go as far as refinement and software bug fixes go.
