In the model year 1989, the new generation of the 911 came onto the market at the same time that the G model was discontinued. The type 964 911 Carrera 4 was made up of 85% new parts but largely retained the classic shapes of its predecessor and was available in Coupé, Targa and Cabriolet bodyshell styles.
Despite extensive similarities in design, the aerodynamics of the 964 were significantly improved compared with the G model. The new, rounded front and rear sections and an automatically extending rear spoiler contributed to these improved aerodynamics.
The 911 Carrera 4 was the first all-wheel-drive 911. Its electronically controlled permanent all-wheel drive normally directed 31% of the drive torque to the front axle and 69% to the rear axle, though the distribution could be varied depending on the driving situation. There was a traction control switch on the Carrera 4's centre console. Its 3.6-litre engine delivered 250 PS of power.
From model year 1990, the 911 Carrera 2 – an identical rear-wheel drive version and the first model with Tiptronic – was launched, and from model year 1991 a Turbo variant was also available.
