Porsche 911 Carrera 2 Cabrio, 1993

Porsche 911 Carrera 2 Cabrio, 1993

The 964 was considered over 85% new as compared over its predecessor, the Carrera 3.2. The first 964s available in 1989 were all wheel drive equipped "Carrera 4" models; Porsche added the rear wheel drive Carrera 2 variant to the range in 1990. Both variants were available as a coupe, Targa or Cabriolet. The 964 Carrera was the last generation sold with the traditional removable Targa roof. Later evolutions of the Targa, starting with the 993 generation, replaced that setup with a complex glass-roof "greenhouse" system. A new naturally-aspirated engine called the M64 was used for 964 models, with a flat-6 displacement of 3.6 litres. Porsche largely revised the suspension replacing the rear torsion bars with coil springs and shock absorbers. Power steering and ABS brakes arrive to the 911 for the first time and they were both made standard. The exterior bumpers and fog lamps became flush into the car, allowing for better aerodynamics. A new electric rear spoiler raised at speeds above 50 mph (80 km/h) and lowered down flush with the rear engine lid at lower speeds or when stopped. A revised interior featured standard dual airbags beginning in 1990 for all North American production cars. A new automatic climate control system provided superior heating and cooling. Revised instrumentation housed a large set of warning lights that were tied into the car's central warning system which alerted the driver to a possible problem or malfunction.
