N O TA B L E H I G H L I G H T STwo electric motors control the toe-control links that steer the rear wheels up to 1.5 degrees. At low speeds, the rear wheels steer in the opposite direction of the fronts to increase the yaw rate. Above 50 mph, the rear wheels steer in the same direction as the fronts for greater high-speed stability.

CAR AND DRIVER TEST RESULTS

TEST NOTES: We attempted a launch using the “paddle neutral” scheme, but the engine bogs as the clutch slams shut. The real launch-control program manages the clutch and wheelspin judiciously to knock off 0.3 second. Upshifting with the paddles shaves off another tenth.

HANDLINGROADHOLDING, 200-FT-DIA SKIDPAD ............... 1.12 gUNDERSTEER ....................... MINIMAL

TEST NOTES: The GT3 is absolutely neutral around the skidpad. At the limit, it’s much easier to provoke understeer than it is to break the 305/30 Michelin Pilot Sport Cup 2 tires loose at the rear.
