the central pipe guides gases released from the wastegate of the turbochargers. The suspension setup was similar to the GTO's double wishbone setup, though many parts were upgraded and settings were changed; the unusually low ground clearance prompted Ferrari to include the ability to raise the vehicle's ground clearance when necessary for later cars via hydraulic lift chambers in the front dampers. Body and interior The body was an entirely new design by Pininfarina featuring panels made of Kevlar, carbon fibre, and aluminium for strength and low weight, and intense aerodynamic testing employed. Weight was further minimised through the use of a polycarbonate plastic windshield and windows. The cars did have moderate air conditioning but had no sound system, door handles, glove box, leather trim, carpets, or door panels. The first 50 cars produced had sliding Lexan windows, while later cars were fitted with wind-down windows. All cars technically left the factory in "Rosso Corsa" colour and left-hand drive. At least seven cars were modified and delivered to the Sultan of Brunei in right-hand drive. The Sultan employed Pininfarina's prototype manager Paolo Garella to make modifications to the cars (colour, power, interior comforts). Aerodynamics Cooling was important as the forced induction engine generated a great deal of heat. As a consequence, the car was somewhat like an open-wheel racing car with a body. It had a partial undertray to smooth airflow beneath the radiator, front section, and the cabin, and a second one with diffusers behind the engine, but the engine bay was not sealed. It has a . Tyres Owing to the fact that the car had an additional 80 bhp compared to the 288 GTO, a new tyre had to be developed to cope with the power levels which were more typically associated with racing cars. Materazzi leaned on his good experience with the Pirelli head of development Mario Mezzanotte, who he had known since the rallying years with the Lancia cars. Pirelli made a carcass with light materials (including Kevlar) after the experience gained in the Formula 1 seasons from 1980 to 1985 and asymmetrical tread patterns to create the P-Zero specifically for the F40. Launch and promotion The F40 was revealed on 21 July 1987 at the Civic Centre in Maranello. Originally the presentation was due to happen at the Frankfurt motorshow according to Materazzi but FIAT needed to present the Alfa Romeo 164 at that
