It is mounted on the trunk lid (which can be conveniently released from the driver's seat) and swings up with it. The 944 Cabrio, which entered production in 1989 and proved exceptionally popular right from the start, remains unchanged. The following 944 versions will be offered for sale on the German market in the 1991 model year:

Automatic lap-and-diagonal a seat belts are provided for rear-seat passengers too; the interior light has a timer for delayed switch-off, lockable wheel studs are provided and the headlight beams are now adjustable from the driver's seat - a whole series of worthwhile new features on the 944 S2.

For Porsche drivers who intend to use their 944 S2 for competition work, Porsche offers three-element suspension package, with firmer springs and the wheels and brakes from the a high-performance 944 Turbo. The Cabrio, based on the powerful 944 S2 which is such a pleasure to drive actively, combines this model's well-balanced transaxle layout with all the appeal of open-car driving. The soft top, the outline of which recalls the Speedster, has an electric extending and retracting mechanism, which makes it very easy to open and close. The Porsche 944 Turbo occupies one of the leading places among the world's genuine high-performance cars. The 250 bhp engine, race-proved in Porsche 944 Turbo Cup events, and the excellent suspension and brakes with their similar competition background are guarantee of quite exceptional performance and road behavior. With improvements introduced for the 1991 model year, this high-grade sports car has become even more attractive and good value for money.
