STEERING FROM THE REAR
The principle of rearwheel steering – that’s the mechanical system rather the gorgeously subtle state of power-oversteer – is simple, and the on-paper beneits nice to have. The GT R is the irst production AMG with the system, and below 62mph the rear wheels turn in the opposite direction to the fronts, helping the car turn tighter and monster twisty roads and racetracks. Such a set-up would be impossibly nervous at speed, so beyond 62mph the rear wheels turn in the same direction as the fronts, eectively lengthening the car’s wheelbase and creating a stability that breeds conidence at speed.
All well and good but the reality can be odd, with the system coming between car and driver to corrupt your intuitive understanding of what the thing’s doing, and how it might behave at any given moment. At its worst, rearsteering breeds a pervasive nervousness that haunts your every move – step forward the Ferrari F12 tdf. But just as Ferrari evolved the system to create the far more together 812 Superfast, so Porsche’s 911 GT3 proves it can be all but imperceptible, working its magic to shrink the car in tight going without spoiling that all-important sense of connection.
