Porsche shows steering system enables the rear wheel of the new 911 GT3
One of the novelties of the 2014 Porsche 911 GT3 is its system of active steering of the rear wheels, which help the front contour curves. The adoption of this solution in a production car in assembler and is unprecedented in this video, we can see it working first.
At speeds up to 50 km / h, the rear wheels in the opposite direction ester?am the front. Going 80 km / h, the system reverses its operation, causing the wheels to act in the same direction of the front in order to increase the stability of the whole. Two actuators are responsible to steer the rear wheels up to 1.5 degree.
The supercar has a boxer six-cylinder engine, 3.8 liters and delivers 481 horsepower and 44.66 lb-ft of torque sent to the rear by a dual-clutch transmission with seven speeds and a self-locking differential wheels. The car goes from zero to 100 km / h in 3.5 seconds, and reaches at 315 km / h.
