BMW was starting to exert pressure on March to quit F1 and concentrate on F2. Patrick Depailler took the F2 championship in an Elf-sponsored March-BMW, the marque's last title for several years as the Elf sponsorship programme and (in 1976) the arrival of Renault engines turned the formula into a French benefit. Some discontent arose in the March customer ranks in F2 since the works appeared after the first couple of F2 races with cars that differed significantly from the customer vehicles. In the following year Brambilla and Lella Lombardi made March Engineering history. At the 1975 Spanish Grand Prix Lombardi became the first woman to score a championship point in Formula One while Brambilla scored a surprise victory at the 1975 Austrian Grand Prix, giving the team its maiden win. (As both races were rain-shortened, all participants received only half of the points). During the same weekend of the Austrian Grand Prix, Mark Donohue died after a practice accident in a Penske-owned March. Penske had abandoned their own car and bought a March to allow them to continue competing. Through the mid-1970s, March provided privateers with simple, fast, and economical cars; at one point Frank Williams bought an allegedly brand new 761B only to discover that it still had orange paint on it from its time as a 751 with Brambilla driving. In 1976, Peterson, unhappy with the uncompetitive Lotus, left the team early and returned to March for whom he scored the team's second and last win at Monza. The 761 was fast but fragile, with the F2 components starting to show the strain; by this point the F1 effort was being run on a small budget with a two-car works effort featuring Peterson and Brambilla, the cars tending to turn up in different liveries as race-by-race sponsorship deals were signed, and a B-team entered under the March Engines banner for Stuck and Arturo Merzario. By now the F1 effort as a whole was under fairly severe pressure from BMW, which wanted Herd to concentrate entirely on the works' Formula Two effort, which was starting to be outpaced by French constructors (Martini and Elf) and the new Ralt marque. That year Peterson scored only one other point in 1976 before being brokered back into a deal with Tyrrell for 1977. Although he felt most at home at March, it was clear that the team did not have the
