Grid penalty for Hamilton after gearbox change In Gulf Air Bahrain Grand Prix

Lewis Hamilton will drop five places on the grid for the 2013 Formula 1 Gulf Air Bahrain Grand Prix following a gearbox change, Mercedes have confirmed.

The 2008 world champion suffered an apparent left-rear tyre delamination at the end of final practice on Saturday morning and following an inspection of his F1 W04, the team opted to replace the gearbox before qualifying.

Hamilton becomes the third driver who will drop places following qualifying in Sakhir. Mark Webber was given a three-place grid penalty for tangling with Toro Rosso's Jean-Eric Vergne at the previous race in China, while Sauber's Esteban Gutierrez received a five-place penalty in Shanghai for causing a collision with Force India's Adrian Sutil.
