The Porsche 964 came onto the market in model year 1989, at the same time as the phasing-out of the G series. The 911 Carrera 4 type 964 contained 85 percent new parts, but largely retained the classic shape of its predecessor. It was available in the coupé, targa and cabriolet body designs.
Despite many similarities in the design, the 964 had much better aerodynamics than the G model. This was helped in particular by the new round front and rear sections as well as an automatically extending rear spoiler.
The 964 Carrera 4 was the first 911 to feature an all-wheel drive system. Its electronically controlled permanent all-wheel drive normally transmitted 31 percent of the drive torque to the front axle and 69 percent to the rear axle. Distribution could be varied according to the relevant driving situation. Its 3.6-litre engine produced 250 hp.
As of model year 1990, an identical rear-wheel drive version became available in the form of the 911 Carrera 2 and another Turbo version as of model year 1991.
The 964 Turbo had a wider body with significantly more flared wheel housings compared to the Carrera models. At the rear, the rear wing largely adopted from the Turbo 3.3 of the G model as well as two oval tailpipes emphasised the vehicle’s uniqueness. In model years 1991-92, the 911 Turbo was powered by a turbocharged 3.3-litre engine with 320 hp. In MY 1993, it received a 3.6-litre engine with a power output of 360 hp. One of the distinguishing features of this version were the red brake callipers and 18” Speedline rims.
The 1991 Carrera RS, with it’s 4cm lower ride height, additional 10hp and 200kg weight saving was the weapon of choice for those who preferred driving dynamics over comfort. In 1992 the Carrera RS 3,8 was the first road legal 911 to offer 300 atmospheric hp.
