Porsche introduced the 911 Carrera 4 in 1989. It was the all-wheel-drive launch version of the new 964 generation, replacing the 911’s preceding 930-based range.
The 964 represented a major engineering update, despite retaining the familiar rear-engined silhouette. Porsche described it as roughly 85% new compared with the Carrera 3.2. It introduced coil springs and shock absorbers in place of torsion bars, along with standard anti-lock brakes and power steering.
The Carrera 4’s all-wheel-drive system was derived from technology developed for the Porsche 959. Early 964 cars available in 1989 were Carrera 4 models, offered in coupé, Targa and cabriolet body styles. The rear-wheel-drive Carrera 2 joined the range in 1990, which is a common source of confusion when comparing launch dates.
The 964 Carrera 4 used a new 3.6-litre naturally aspirated flat-six engine. Its electronic four-wheel-drive system normally sent more torque to the rear, preserving the traditional 911 driving character while improving traction and stability.
