Lewis Hamilton said he is fuelled by criticism after completing the final outing in his Ferrari ahead of his full debut for the Italian giants at next month’s Formula One curtain raiser in Australia.
Hamilton set the sixth quickest time as testing drew to a close in Bahrain, and completed 47 laps to take his tally for the week to 162 – the equivalent of nearly three race distances.
