The high-speed test of "auto motor and sport" in Nardo in southern Italy is the ultimate challenge for all vehicle manufacturers. High temperatures and the fastest automobile race track in the world that knows only one load condition: full throttle. The 12.3 km-long route is basically a circle with a diameter of 4 km and an elevated roadway that is reminiscent of a steep curve. In practice, this results in an infinite straight line for miles of continuous full load driving, an operating condition that puts utmost load on the engine. Add uncomfortably high ambient temperatures and it simply doesn’t get any more challenging.
