Ferrari 1991 F40

• The Ferrari F40 (tipo F120) is a mid-engine, rear-wheel drive sports car engineered by Nicola Materazzi with styling by Pininfarina. It was built from 1987 to 1992, with the LM and GTE race car versions continuing production until 1994 and 1996 respectively.

• As the successor to the 288 GTO (also engineered by Materazzi), it was designed to celebrate Ferrari's 40th anniversary and was the last Ferrari automobile personally approved by Enzo Ferrari. At the time it was Ferrari's fastest, most powerful, and most expensive car for sale. As early as 1984, Materazzi had proposed to Enzo Ferrari the idea of using the Group B 4-litre category (2.857-litre if turbocharged) to prove the performance of new road cars which with increased power could no longer safely display their performance on the road in the hands of regular buyers.

• Since Enzo Ferrari no longer had control over the production part of the business, Materazzi had to obtain permission from the General Manager Eugenio Alzati. Permission was granted but only at the condition that work would take place outside of the Monday to Friday work week. A very small team thus developed the GTO Evoluzione on Saturdays to compete in the same class entered by the Porsche 959 in FIA Group B.

Design

• Gearing, torque curves and actual power output differed among the cars. The F40 did without a catalytic converter until 1990, when US regulations made them a requirement for emissions control reasons. The flanking exhaust pipes guide exhaust gases from each bank of cylinders while 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

• 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.

Performance

• Power came from an enlarged, high-revving 2,936 cc (2.9 L; 179.2 cu in) version of the 288 GTO's IHI four-stroke 90 degree twin turbocharged and intercooled V8 engine generating a peak power output of 478 PS (471 hp; 352 kW) at 7,000 rpm and 577 N⋅m (426 lb⋅ft) of torque at 4,000 rpm as stated by the manufacturer

• The first independent measurements yielded 0-100 km/h (62 mph) in 4.7 seconds and a top speed of 321 km/h (199 mph) onto the French Sport Auto September 1988 cover.

• The next opportunity to reach the claimed top speed was a shootout at Nardò Ring organized by Auto, Motor und Sport. Ferrari sent two cars but neither could reach more than 321 km/h (199 mph), beaten by the Porsche 959 S, which attained a top speed of 339 km/h (211 mph), and the Ruf CTR, which attained a top speed of 342 km/h (213 mph). Both were limited production cars with only 29 built, so while the F40 never was the world's fastest sports car as self-appraised by Ferrari, it could still claim the title of the fastest production car with over 500 units built until the arrival of the Lamborghini Diablo (depending on how the term "production car" is defined).[47][48][49] Road & Track measured a top speed of 315 km/h (196 mph) for both the European and US spec cars while Car and Driver measured a top speed of 317 km/h (197 mph).[14][50][51]
