Masten Gregory and the German Kremer Racing team. Kremer himself rejoined Nic Koob in another 2.4, along with Günther Huber in what was the first example of a triple-driver combination. In a reduced under-2 litre class, the Écurie Léopard tried taking on the Porsches with a 1.6-litre Alpine A110. So Porsche established a single-make record with 33 starters from the field of 49 – a trend that would carry on through the 70s and 80s. Practice The test weekend in April had shown the chassis development on the 917 had made them even faster. Jackie Oliver becoming the first person to record a 250 kp/h lap with an incredible time of 3:13.6 equating to 250.5 kp/h (155.6 mph). In June, Rodríguez followed up that form with a 3:13.9 in the JWA Porsche to put a 917 on pole. This was underlined by Vic Elford coming in second, going five seconds faster using the same car as he had the previous year. Third was the second Wyer car, nearly four seconds behind his teammate. Jo Siffert had had a big moment during practice when he approached Maison Blanche at near 290 kp/h (180 mph). Bill Tuckett in the Paul Watson Porsche did not see him approaching and took his standard line. Swerving to avoid the 911, Siffert got the car into a series of spins but amazingly only lightly tapped the barriers situated right next to the track. He got back to the pits, shaken and livid, and stormed off to the stewards' office to protest. After a problematic practice session, Penske's Mark Donohue was the fastest of the Ferraris, in fourth just ahead of the second Martini Porsche and Vaccarella in the Spanish Ferrari. The "Pink Pig" Martini 917/20 special was a strong 7th with a 3:21.1. After blowing their engine up on Thursday, the Filipinetti 512F team was able to borrow one from the Penske crew and with it they qualified 8th. Likewise, the Piper Ferrari had problems in practice. The clutch had broken on Wednesday and on Thursday the car kept jumping out of gear. At one point Chris Craft was approaching Maison Blanche at 280 km/h when it skipped into neutral. Despite that he was able to get 9th on the grid. Fastest of the 3-liter Prototypes was the Matra in 16th (3:31.9), well ahead of the Ligier in 17th (3:39.8), while the Léopard Corvette was the
