Porsche 911 Carrera 4 964

The Porsche 964 Carrera 4, which debuted as a 1989 model and entered full production in 1990, was one of the most significant 911s ever produced. It represented a comprehensive modernization of the 911 platform while respectfully maintaining the car's essential character. Most dramatically, it was the first production 911 to feature all-wheel drive, a technology trickled down from the legendary 959 supercar.

The 964 was internally viewed as approximately 87 percent new compared to the outgoing 3.2 Carrera, though its visual evolution was deliberately subtle. The bumpers were now integrated into the body rather than being separate units, giving the car a smoother, more cohesive appearance. An electrically deployed rear spoiler rose at speed and retracted at rest, replacing the whale tail fixed spoiler of the Turbo. Beneath the familiar silhouette, however, virtually everything had changed.

The most significant engineering advancement was the suspension. For the first time in 911 history, coil springs replaced the torsion bars that had been a defining feature of the 911 since 1963. The new MacPherson strut front and semi-trailing arm rear layout with coil springs provided a dramatic improvement in ride quality while maintaining the handling precision Porsche customers demanded. The 964 rode like a modern sports car while its predecessors had always felt like barely civilized race cars.

The all-wheel-drive system was a technological tour de force. Derived from the 959 program, it featured a planetary center differential that distributed torque with a 31/69 front-to-rear split under normal conditions. A sophisticated electronic management system could vary the torque split based on wheel slip, sending more power to the axle with better traction. The system added approximately 100 kilograms over the rear-wheel-drive Carrera 2 that arrived a year later, but the additional weight was offset by massively improved traction, particularly in wet conditions.

The engine was a thoroughly revised 3.6-liter air-cooled flat-six producing 250 horsepower. Compared to the outgoing 3.2, the new engine featured dual spark plugs per cylinder, knock sensors, a more efficient exhaust system, and Bosch Motronic M2.1 engine management. The result was an engine that was more powerful, cleaner, more fuel efficient, and smoother than its predecessor while maintaining the essential air-cooled character that defined the 911 experience.

Porsche equipped the Carrera 4 with ABS brakes as standard, another first for the 911 line. Four-piston fixed calipers gripped cross-drilled ventilated discs at all four corners, providing stopping power commensurate with the car's performance. Power steering, also a first for the 911, was standard equipment, though purists complained it filtered some of the road feel that made older 911s so communicative.

The interior received a comprehensive update with a new dashboard design, improved HVAC system, and better ergonomics throughout. Standard equipment included electric windows, central locking, and an improved sound system. The Carrera 4 was positioned as the flagship of the 911 range, priced above the Carrera 2 that followed and reflecting the complexity of its all-wheel-drive system.

On the road, the 964 Carrera 4 offered a distinctly different character from both its predecessors and its rear-wheel-drive sibling. The all-wheel-drive system provided a sense of security that was new to the 911 experience, particularly in challenging conditions. The car could be driven hard in the rain with a confidence that would be unthinkable in a rear-drive 911. The coil-spring suspension provided a compliance and sophistication that made long-distance driving genuinely comfortable for the first time in a 911.

Today, the 964 Carrera 4 is enjoying a strong appreciation in values as collectors recognize its significance in the 911 lineage. It was the car that proved the 911 could evolve without losing its soul, the car that brought all-wheel drive to the 911 family, and the car that replaced torsion bars with coil springs. While the rear-wheel-drive Carrera 2 is often preferred by driving purists, the Carrera 4 offers an all-weather capability and a historical significance that make it a compelling collector car in its own right.
