Pastor Maldonado will require a new gearbox in his Williams FW34 for the Bahrain Grand Prix, and will therefore start five places lower than he qualifies.
The team discovered an issue with the unit on Friday and notified the FIA that they would be changing it prior to the race on Sunday.
As per article 28.6 A, of the sporting regulations, a gearbox must last for five consecutive events.
“Each driver may use no more than one gearbox for five consecutive events in which his team competes. Should a driver use a replacement gearbox he will drop five places on the starting grid at that Event and an additional five places each time a further gearbox is used.”
