Porsche 1987 MY: the 944 USA model

An important safety factor is the anti-lock braking system, now available


All 944 models have new safety features, accessories and other options. Porsche is the first manufacturer to offer airbags for both driver and front seat passenger. Dual airbags are standard in the 944 Turbo and optional in the 944S and 944. Porsche offers an optional anti-lock braking system on all 944 models as well.

New accessories include a new rear seat unit with individually folding backs to permit better passenger and load handling. In early 1987, a sound package will be available which includes a Blaupunkt BEA 80 booster/equalizer that allows adjustments to each of 10 built-in speakers.

PCNA price was set at $25,500.
