he Porsche 944 is a sports car built by Porsche from 1982 to 1991. It was built on the same platform as the 924, although 924 production continued through 1988. The 944 was intended to last into the 1990s, but major revisions planned for a 944 S3 model were eventually rolled into the 968 instead, which replaced the 944. The 944 was a successful model and was available as both a coupe and cabriolet in naturally aspirated and turbocharged forms.
944 Turbo (951/952)
For the 1986 model year Porsche introduced the 944 Turbo, known internally as the 951 (952 for right-hand drive models). This had a turbocharged and intercooled version of the standard car's engine that produced 220 hp (164 kW) (217 hp (162 kW) in the US) at 6000 rpm. The turbo was the world's first car using a ceramic portliner to retain exhaust gas temperature. The Turbo also featured several other changes, such as improved aerodynamics, a strengthened gearbox with a different final drive ratio, standard external oil coolers for both the engine and transmission, standard 16 inch wheels (optional forged Fuchs wheels), and a slightly stiffer suspension to handle the extra weight. Major engine component revisions, more than thirty in all, were made to the 951 to compensate for increased internal loads and heat.
1987 Porsche 944 Turbo (US Model)
Few changes occurred for the 1987 model year. They included the deletion of the transmission oil cooler, a change in suspension control arms in order to reduce the car's scrub radius, and for the first time ever offered in a production car, standard dual airbags. The engine remained the same M44/51 powerplant as in the 1986 model. In 1988, Porsche introduced the Turbo S option package (SE in the UK). The 944 Turbo S had a more powerful engine (designation number M44/52) with 250 hp (186 kW) and 250 lb·ft (340 N·m) torque (standard 944 Turbo 217 hp (162 kW) and 243 lb·ft (329 N·m)). This higher output was achieved by using a larger #8 turbine housing and revised engine mapping which allowed for slightly more boost at high rpms as compared to the standard Turbo. In June 1988, Car and Driver tested the 944 Turbo S and achieved a 0-60 mph time of 5.5 seconds and a quarter-mile time of 13.9 seconds at 101 mph (163 km/h). Top speed was factory rated at 162 mph (261 km/h).
The 944 Turbo S's suspension was the then state-of-the-art "M030" option consisting of Koni adjustable shocks front and rear, with ride height adjusting threaded collars on the front struts, progressive rate springs, larger rear torsion bars, harder durometer suspension bushings throughout, larger 26.8 mm (1.1 in) anti-roll bars at the front, and chassis stiffening brackets in the front frame rails. The air conditioning dryer lines are routed differently to clear the front frame brace on the driver's side. The 944 Turbo S wheels, known as the Club Sport design, were 16-inch forged and flat-dished, similar to the Design 90 wheel. Wheel widths were 7 inches (178 mm) in the front, and 9 inches (229 mm) in the rear; sizes of the Z-rated tires were 225/50 in the front and 245/45 in the rear. The front and rear fender edges were rolled to accommodate the larger wheels. The manual transmission (case code designation: AOR) of the 944 Turbo S brought back the external cooler, and also featured a limited slip differential with a 40% lockup setting. The Turbo S front brakes were borrowed from the Porsche 928 S4, with larger 4-piston fixed calipers and discs; rear brakes remained the same as a standard Turbo. ABS also came standard.
The 944 Turbo S interior featured full power seats for both driver and passenger, where the majority of the factory-built Turbo S models sported a "Burgundy plaid" (Silver Rose edition) but other interior/exterior colors were available. A 10-speaker sound system and equalizer + amp was a common option.
In 1989 the 'S' designation was dropped from the 944 Turbo S, and all 944 Turbos featured the 'S' package as standard.
