MONZA, Italy, Sept 6, 2007 (AFP) - The McLaren-Mercedes Formula One team has been fined 50,000 dollars by motor sport´s ruling body (FIA) for failing to crash test a new gear box prior to Lewis Hamilton's victory in Hungary.

A source from the sports governing body said Thursday the team had been fined because it had broken FIA rules.

However the cars of winning driver Alonso and fifth-placed teammate Lewis Hamilton both had new ultra-light gear boxes during the Hungarian Grand Prix on August 5 which had not be crash tested, the source said.
