Porsche 911 Carrera Cabriolet

The price of the first 911 Carrera was $45,565.

In 1984, the 3.0 L SC model was replaced by a new 3.2 L car badged "911 Carrera" but also known as the "3.2 Carrera". The Power was increased to 207 bhp (154 kW)— later 217 bhp (162 kW)— for models in the United States and to 231 bhp (172 kW) for the rest of the world. This version of the 911 had a 0–60 mph (100 km/h) time of 5.4 seconds and a top speed of 150 mph (242 km/h) as measured by Autocar. Making the new carrera of 1984 almost as fast as the 3.3 turbo and almost identical to 100 km/h/62 mph.



The new swept volume of 3164 cm³ was achieved using the 95 mm bore (found in the 1976 Carrera 3.0 L) combined with the 1978 Turbo 3.3 crankshaft's 74.4 mm stroke. In addition, higher domed pistons increased the compression ratio from 9.8 to 10.3:1. New inlet manifold and exhaust systems were fitted. The difference in power being around 15%, the gear ratios of the 915 gearbox matched it so well that it was able to create drivable power from tickover in 3rd, and once 3500 rpm was reached the car was propelled forward with such urgency and venom. It was this flexibilty that made this particular engine one of the greats.

The brake discs were improved to allow them to cool more quickly and, in addition, driving refinement and motor reliability were improved with an upgrade of the fuel and ignition control components to a Bosch DME (Digital Motor Electronics) system. A major improvement in fuel-efficiency was due to the DME providing a petrol cut-off on the overrun.


The non-Turbo models became available as "Turbo-look" or "Super Sport" in 1984, a style that resembled the Turbo with wide wheel arches and the "whale-tail", it also featured the stiffer turbo suspension and the four piston aluminium brembo calipers with the bigger, drilled and vented, disks found on the turbo models and developed from the Porsche 917 brakes. The Super Sport also had the wider turbo wheels. In 1987, the Carrera got a new five-speed gearbox sourced from Getrag, model number G50. This included a hydraulic clutch.

The 911 Speedster, a low-roof version of the Cabriolet which was evocative of the Porsche 356 Speedster of the 1950s, was produced in limited numbers. The 1987 Carrera Club Sport, of which 340 were produced, is a collectible 911 that had a blueprinted engine with a higher rev limit, and had the electric windows, electric seats, and radio removed to save a claimed 50 kg (110 lb) in weight. In fact this particular marque of this vehicle was and still is arguably the one to have.
