Porsche 964 Speedster, 1993

Porsche 964 Speedster, 1993

The Porsche 964 Speedster, a low-roof convertible version of the 964, returned in October 1992. Based on the Carrera 2, the Speedster was available either in standard or in lightweight version, Clubsport trim. Unlike its predecessor, the 911 Speedster, the Porsche 964 Speedster was initially not available with the "Turbo-Look" wider rear arches. As a result, the sales of the 964 edition were disappointing: only 925 units were built in two years, vs 2065 for the previous generation. In late 1993 (Model Year 1994), 20 (14 in right hand drive) very exclusive "Turbo-Look" units were made as special orders and carried special 5 digit option codes in their production records. These "Turbo-Look" Speedsters were some of the last 964's produced by the Porsche factory.

Porsche 911 Turbo, 1993

Porsche introduced the 964 Turbo model in March 1990 as the successor to the Porsche 930. Unfortunately, they hadn't had the necessary time to develop a turbocharged version of the 3.6 litre M64 engine, and choose to re-use the 3.3 litre engine from the 930, with several minor revisions that made the engine smoother, less prone to turbo lag and more powerful, with a total output of 320 PS (240 kW; 320 hp) @ 5750 rpm. A total of 3,660 of the 964 Turbos were built.

In 1992, the 3.3 litre Turbo S was introduced. With a power of 381 PS (280 kW; 376 hp) and with a lightweight interior and limited "creature comforts" the Turbo S was one of the fastest cars on the road. With lowered suspension, a front strut brace and manual steering, the Turbo S was all about performance. About 80 cars were produced during the only year of production.

Porsche released the 964 Turbo 3.6 in January, 1993, now featuring a turbocharged version of the 3.6 litre M64 engine and producing 360 PS (260 kW; 360 hp) @ 5500 rpm, the 3.6 litre powered Turbo was produced only for model year 1993/1994, with fewer than 1,500 of them produced in total, making it one of the rarest and most sought after Porsches produced since the 959.

At the end of 964 production in 1994 the Porsche factory had some 90 Turbo chassis left. These were all transferred to Porsche Exclusiv and built as the very special Turbo 3.6S. The Turbo 3.6S was available either with the traditional 964 Turbo 3.6 body, or with the exclusive Flatnose (German: Flachbau) aka Slantnose option.

Option X83 (Japan), X84 (ROW) and X85 (USA), the Turbo S Flatnose, was available in the US as a $60,179 USD option on top of the base price $99,000 USD Turbo 3.6. The "Flatnose" option was available when ordering the no charge '36S' option '1994 Turbo "S" Model'. In addition to the Flatnose fenders, it also included the 'X88' option or the 'Turbo S' motor, the 'X92' Exclusive front spoiler, 'X93' Exclusive rear spoiler and 'X99' Exclusive rear fender vents. The flatnose option was designed around the model 968 front end for the ROW and USA versions and the 930 style Turbo S front end for Japan (right down to the sill covers on the fenders). 39 Models were made for US markets, 27 for the Rest of the world, and 10 for Japan all in Polar Silver.

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.
