Porsche 959
The Porsche 959 was a sports car manufactured by Porsche from 1986 to 1989, first as a Group B rally car and later as a legal production car designed to satisfy FIA homologation regulations requiring that a minimum number of 200 street legal units be built. During its production run, it was hailed as being the most technologically advanced road-going sports car ever built and the harbinger of the future of sports cars. The water-cooled cylinder heads combined with the air-cooled block, 4-valve heads and sequential turbochargers allowed Porsche to extract 331 kW (444 hp) from the compact, efficient and rugged power unit. The use of sequential twin turbochargers rather than the more usual identical turbochargers for each of the two cylinder banks allowed for smooth seamless delivery of power across the engine RPM band, in contrast to the abrupt on-off power characteristic that distinguished Porsche's other turbocharged engines of the period. The engine was used, virtually unchanged, in the 959 road car as well. In an attempt to create a rugged, lightweight shell,Porsche adopted an aluminium and Aramid (Kevlar or Twaron) composite for body use along with a Nomex floor,instead of the steel normally used on their production cars. The vehicle's weight of 3,190 pounds (1,450 kg) helped to achieve its high performance level. The street version of the 959 debuted at the 1985 Frankfurt Motor Show as a 1986 model, but numerous issues delayed production by more than a year. The car was manufactured in two levels of trim, "Sport" and "Komfort", corresponding to the race version and the street version. First customer deliveries of the 959 street variant began in 1987, and the car debuted at a cost of $225,000 USD per unit, still less than half what it cost Porsche to build each one. Production ended in 1988. In total, 337 cars were built, including 37 prototypes and preproduction models. At least one 959 and one 961 remain in the Porsche historic hall in Stuttgart, Germany.

Ferrari F40
The Ferrari F40 is a mid-engine,rear-wheel drive, two-door coupe sports car produced by Ferrari from 1987 to 1992 as the successor to the Ferrari 288 GTO. From 1987 to 1989 it held the title as the world's fastest street-legal production car,and during its years of production, was Ferrari's fastest, most powerful, and most expensive car. The car debuted with a factory suggested retail price of approximately US$400,000,although some buyers were reported as paying as much as US$1.6 million. A total of 1,315 F40s were produced. Ostensibly, the F40 was conceived as the successor to the 288 GTO and designed to compete with vehicles such as the Porsche 959 and Lamborghini Countach. Power came from an enlarged, 2.9 L (2936 cc) version of the GTO's twin IHI turbocharged V8 developing 478 PS (352 kW; 471 hp) under (16 psi) of boost. The F40 did without a catalytic converter until 1990 when US regulations made them a requirement for emissions control reasons. The body was an entirely new design by Pininfarina featuring panels made of kevlar, carbon fiber, and aluminum for strength and low weight, and intense aerodynamic testing was employed. Weight was further minimized through the use of a plastic windshield and windows and no carpets, sound system, or door handles were installed although the cars did have air conditioning. Early cars had fixed windows, although newer windows that could be rolled down were installed into later cars. It had a partial undertray to smooth airflow beneath the radiator, front section, and the cabin, and a second one with diffusers behind the motor, but the engine bay was not sealed. Nonetheless, the F40 had an impressively low Cd of 0.34 with lift controlled by its spoilers and wing.
Performance:
The F40's light weight of 1,100 kg and high power output of 478 PS at 7000 rpm gave the vehicle tremendous performance potential. Road tests have produced 0-100 km/h (62 mph) times as low as 3.8 seconds (while the track only version came in at 3.2 seconds), with 0-160 km/h (100 mph) in 7.6 seconds and 0-200 km/h (125 mph) in 11 seconds giving the F40 a slight advantage in acceleration over the Porsche 959, its primary competitor at the time. The F40 was the first road legal production car to break the 200 mph (322 km/h) barrier. From its introduction in 1987 until 1989, it held the record as the world's fastest production car, with a top speed of 324 km/h (201 mph).
