Porsche 911 GT3 rear axle steering explained in a new video
Unveiled back in May last year, the latest 911 GT3 features state of the art rear axle steering. What this does is gives the 2014 911 GT3 an un-rivaled steering response. Explained on paper till now, here is a video of the system, which explains how it works.
Powered by a 3.8l turbocharged six cylinder engine, the new 911 GT3 delivers 520 HP for the Turbo, and 560 HP for the Turbo S. This power is delivered to all four wheels via 7 speed dual clutch transmission (PDK) giving the car a 0-100 kmph time of just 3.1 seconds, and a top speed of 318 kmph.
To improve cornering and stability at such high speeds, Porsche has given 911 GT3 a rear axle steering. For speeds of over 80 kmph, the intelligent rear axle steering turns the rear wheels in the same direction as that of the front wheels, by upto 2.8 degrees, depending on driving speed. What this does is virtually increases 911 GT3′s wheelbase by 500 mm, giving it improved stability.
For speeds lower than 50 kmph, when you are in the city and have to find your way out of traffic jams or tight corners, the rear axle steering system turns the rear wheels in the opposite direction to that of front wheels. This virtually lowers the GT3′s wheelbase by 250 mm, making it easier to maneuver.
In another update, Porsche has stated that they have managed to find the problem that has resulted in the recall of all 785 GT3′s sold till date. Speaking to Bloomberg, Porsche CEO, Matthias Mueller said, “We know the reason and the problem-solving measures. We’re testing them.” He did not reveal what was the cause of fire that glutted the two Porsche 911 GT3′s in Europe last month.
