THE PORSCHE 944 SERIES:
FOR 1989, MORE POWER, MANY REFINEMENTS
The 1989 944 series is an eloquent example of Porsche AG's refinement philosophy. The new Porsche 944: a higher performing 2.7 liter 165bhp engine and newly standard comfort and convenience features. The Porsche 944 S2: a new 3.0 liter engine - one of the most powerful fours in the world today - in the same body and chassis as last year's 944 Turbo. And the new Porsche 944 Turbo: the same searing performance as the 944 Turbo S, the roadgoing version of Porsche's famous Turbo Cup car, makes it the fastest 4 cylinder production car ever built. At Porsche, rarely is a single change made to realize one benefit. Rather, goals are clearly stated and then existing technology is synergistically improved to reap an optimized new configuration having multiple benefits. The new 944 engine is a case in point. In seeking better pulling power from low rpm, Porsche engineers specified a displacement increase, from 2.5 to 2.7 liters. But the didn't stop there. They also: raised the compression ratio to 10.9:1; enlarged the intake valves; gave the engine a new camshaft with modified timing;and revised the digital motor electronics (DME) settings. These optimization efforts paid off in an impressive increase in torque, particularly at low rpms. Elsewhere in the 944, there are other refinements... ABS braking and automatic speed control are now standard, the passenger's seat now adjusts electrically in height, the electric sunroof and Charleston radio are standard, as is a new alarm system and larger capacity battery. Naturally, new colors and interiors are available.
