Porsche 911 Turbo, 1993

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.
