The fifth generation Porsche 911 GT3 is the first production sports car from the company to use the active rear-wheel steering system. A few days ago, a video demonstrating the car’s technology has been uploaded on the company’s website.
The active rear-wheel steering system, until speeds of 49 kmph, steer the rear wheels in the opposite direction of the front ones. Once the speed increases at around 80 kmph or higher, the rear wheels turn in the same direction as the front wheels to enhance stability. The rear wheels though don’t turn as much as the front ones and this system controlled by two actuators steers the rear wheels up to 1.5 degrees.
The all-new GT3 is powered by a 3.8-litre six-cylinder boxer engine developing 468bhp and 438Nm of torque. The power is transferred to the rear wheels through a dual-clutch seven-speed gearbox and a locking differential.
