Street word has it that the next-generation Porsche 911 Turbo will receive 4-wheel steering. Awesome!
If Germany’s Autobild is correct, the new Porsche 911 Turbo will make its auto show debut in the fall of 2013, hitting the market (likely in Europe first) in the spring of 2014. As expected, it will benefit from all-wheel-drive and more horsepower (530 hp, versus 500 hp), but it will also add four-wheel-steering to its (already impressive) resume.
As the name implies, four-wheel-steering (also known as all-wheel-steering) improves handling at high speed while (generally) decreasing the turning radius at low speeds. Rear-steering systems can either be passive, generally tuned via bushings to correct rear-wheel toe-out, or active.
