Brawn: F2005 an evolution, not revolution 25 Feb 2005
Ferraris technical director Ross Brawn has declared his faith in the new F2005 machine, launched in Maranello on Friday, insisting it represents a major step forward over its predecessor, despite no revolutionary changes.
There are no radical features of this car but logical progressions in all the areas that we feel make a good racing car, he said of Ferraris 51st Formula One challenger. It is stiffer, lighter, more stable, and, most importantly with the new tyre regulations, it should be less stressful on the tyres.
The F2005, the first Ferrari developed primarily under the leadership of Aldo Costa, features heavily revised aerodynamics, in line with the 2005 regulations, coupled to a lighter but stronger chassis, designed to meet new, stricter FIA crash tests.
The side pods have been adapted to accommodate a new cooling system, while the engine cover has been redesigned, as have the aerodynamic devices on the side pods, with a secondary winglet introduced in the area of the roll-hoop.
The rear of the car has been redesigned around a new, smaller, lighter and stiffer seven-speed gearbox, made of titanium and carbon fibre. The layout of the exhausts is also fundamentally different to that of the F2004, eliminating the aerodynamic profile which characterised its rear section, which is now almost entirely integrated within the bodywork.
The rear suspension has been revised to optimise the efficiency of operation of the cars Bridgestone tyres, while also improving the aerodynamic efficiency of the rear. The floor of the car has also been substantially redesigned to fit in with the new dimensions of the gearbox and comply with the new regulations.
The new 055 V10 engine is an evolution of the 053 unit fitted to the F2004, with most of the components redesigned and optimised to meet the new targets required under the two-weekend engine rule.
Track testing of the F2005 will begin next week with Luca Badoer, with Michael Schumacher and Rubens Barrichello due to get their first taste of the new car in the week following the Malaysian Grand Prix.
