ロルフ・シュトメレン
This year, for an unknown reason, the April test weekend coincided with the British round of the International Championship. Jacky Ickx set the benchmark for JWA, with a 3:35.4 lap, then promptly left for Brands Hatch to win the endurance race. It was also the first appearance of the new Porsche 908, in the hands of Rolf Stommelen. It was found to need major aerodynamic refinement, but Stommelen eventually got a time of 3:44.1.
