Lewis Hamilton ensured that McLaren ended the first of two pre-season F1 tests at Jerez on top of the pile with the quickest time on the final day.

Hamilton posted a quickest time of 1min 19.538secs late on on the final day, to beat the marker set by Jaime Alguersuari earlier in the week having earlier completed a number of longer runs with the car as conditions at the circuit improved following earlier rain.

Hamilton's best time saw him know Adrian Sutil from the top after the German had looked like putting Force India at the head of the times on the final day of its maiden test with the VJM03.
