Although the fundamental design philosophy of the F2003-GA is the same in terms of optimising aerodynamic efficiency, lowering centre of gravity height, maximising the performance available from the Bridgestone tyres and the 052 engine, many areas of the car had to be fundamentally reviewed in order to make a step forward in performance because these areas were close to the limit of development on the F2002. In addition, the areas that have not changed fundamentally have been further refined and optimised to maximise functionality and performance, so almost every part on this car is newly designed.
Aerodynamics - The side pods, radiator layout and inboard rear suspension are fundamentally new. This enabled Ferrari to make a step forward both in terms of aerodynamic performance and cooling efficiency and we have several development items including front wing, turning vanes, brake ducts and revised rear suspension components.
Transmission - Although the transmission is essentially a development of the F2002 transmission, it is considerably shorter, narrower and lighter. The gears were redesigned to save weight and improve durability, the gear selection system was further refined for a faster gearshift. Ferrari also took another step in terms of engine, transmission, rear suspension integration.
Suspension and Steering - The power steering system was fundamentally redesigned. A prototype version was successfully tested on the F2002. Closer cooperation with Bridgestone resulted in an improved understanding of the interaction between tyre and car
and enabled Ferrari to revise the suspension to maximise the performance of the Bridgestone tyres. Both front and rear suspension were revised to maximise the performance of the Bridgestone tyres. The inboard end of the rear suspension has been completely revised and includes a new damper system. Almost all of the suspension components were refined and many have been manufactured using new materials and manufacturing methods in order to reduce weight.
Electronics - The new Marelli Step10 electronic system was incorporated which, with its superior processing speed and power, gave Ferrari improved control of the engine and the gearbox as well as better data acquisition. The system was developed and tested in a F2002.
Michael Schumacher scored a dream result for the new Ferrari 2003-GA in the Spanish Grand Prix on May 4, 2003 when he took its maiden win 5.7 seconds ahead of the Renault of Fernando Alonso. Rubens Barrichello underlined the success of the new Ferrari with a third place finish.
