We're eagerly awaiting the unveiling of the Porsche 911 Turbo and new details are starting to emerge about the upcoming model.

Road & Track says the car will have an output of 520 bhp (387 kW) and 479 lb-ft (648 Nm) of torque in the Turbo and 560 bhp (418 kW) and 516 lb-ft (699 Nm) of torque in the Turbo S. Both models are also slated to feature a PDK transmission and an overboost function that can deliver an extra burst of 37 lb-ft (50 Nm) of torque for up to ten seconds.

In terms of performance, the Turbo should accelerate from 0-60 mph in approximately three seconds and lap the Nürburgring in less than seven minutes and thirty seconds. There is even speculation that the model could match the Carrera GT’s time of 7:25.

Despite the impressive numbers, the car is expected to be 13% more fuel efficient as it is slated to feature start/stop technology and an optimized transmission.

We can also expect an active aerodynamic front spoiler, a rear steering system, optional carbon ceramic brakes and a body that is 1.1 inches wider than the 911 Carrera 4 / 4S.
