The model was brought in at the Spanish Grand Prix, the fifth race of the 2003 season. Chassis 229 is by far the most successful of the six F2003-GAs that were built.
Schumacher drove it to victory in Spain and also won the Austrian, Canadian, Italian and US Grands Prix in the car.
He also claimed pole position in Spain, Austria and Italy in the vehicle, and the fastest laps in Austria, Italy and the United States.
