When the 964-model 911 was launched in 1989, the first variant was the four-wheel-drive Carrera 4. Not so with its replacement, the 993. In this case the two-wheel-drive Carrera (the number 2 was omitted this time round) came first, followed soon after by a Carrera 4.Instead of simply lifting the all-wheel transmission from the 964, Porsche came up with a new system that was substantially lighter, at around half the weight. Designed to aid handling more than traction, this system used a viscous coupling that varied the amount of power delivered to the front wheels from 5 to 39 percent, depending on conditions. It was also a more efficient set-up that ensured that performance and economy didn’t suffer noticeably. Not that Tiptronic transmission wasn’t offered with the Carrera 4.
Standard on the Carrera 4 and, incidentally, an option for the Carrera, was ABD (Automatic Brake Differential). This worked with the ABS sensors to detect wheelspin during acceleration at speeds less than 44mph and when a rear wheel slipped extra torque was transferred to the front axle.
The 993 Carrera 4 offered the benefits of four-wheel-drive but felt more like a true 911 then did the previous model. Indeed, it was hard to think of a reason not to opt for this model.
