In 1989, the all-wheel-drive 964 (called the Carrera 4, also available as the rear-wheeled Carrera 2 by 1990) was released, marking the next major evolution for the model. Integrated bumpers and a retractable spoiler paid homage the lines of the original 911. Power steering and antilock brakes came standard, in their first-ever appearance for the 911.
The first 964 Turbos reused the 930's 3.3-liter engine (tuned to an improved 320-hp) on the new Carrera 4 platform. A super-rare variant called the Turbo S (3.3-liter, 381-hp) was available in 1992, with lowered suspension, manual steering, and a sparse, lightweight interior. About 80 were produced.
