The 944 was introduced in 1981 with a 2.5 litre straight 4 engine whose design was based on one half of the Porsche 928’s V8 engine. While the design was very similar to the V8, very few parts were interchangeable. The 944 was based on the earlier 924 model, but featured numerous changes including updated bodywork with flared fenders and a rear spoiler similar to that on the previous 924 Turbo. The interior was mostly the same as the 924, except for new climate control switches.
In mid 1985 the 944 underwent its first significant changes. The interiors ergonomics and air conditioning system were improved with a completely new dash (oval dash) and door panels, and the radio antenna was moved from a standard vertical position to being embedded in the windshield. The alternator was upgraded from a 90 amp alternator to a 115 amp alternator. Other changes included a change in oil sump capacity, new front and rear cast aluminium control arms and semi-trailing arms, a larger fuel tank, optional heated and powered seats, revised starter, and revisions in the mounting of the transaxle to reduce noise and vibration. The ‘cookie cutter’ style wheels used in the early 944’s were upgraded to new ‘phone dial’ style wheels. 1985 model year cars incorporating these changes are sometimes referred to as ‘1985B‘ or ‘1985 1/2’ cars.
In 1987, the naturally aspirated 944S (Super) variant was introduced. The 944S had a more powerful 190bhp engine, which marked the first use of four valves per cylinder heads in the 944 series. Also in 1987, dual air-bags and an anti-lock brake system were introduced as options on the base model. Wheel offset was increased from 23mm to 52mm to provide clearance for the optional ABS brakes.
In 1990 the 2.7 litre base model was discontinued.
