resources to do Formula One properly. In the off-season of 1976-77, March engineer Wayne Eckersley constructed a rear end for the 761 chassis that had four driven wheels (designated the March 2-4-0) to Robin Herd's design. Unlike the six-wheeled Tyrrell P34, the 2-4-0 had four 16-inch driven wheels at the rear (the same size as the front wheels). The theory behind the design was that this arrangement would offer improved traction and reduced aerodynamic drag (compared to the Tyrrell, which used ultra-small front wheels and normally sized rears). The chassis was tested at Silverstone circuit in early 1977 by both Howden Ganley and Ian Scheckter but the project was curtailed in favour of further development of the conventional chassis. The car made March more profit than many of its successful racing cars as it was licensed by Scalextric and became one of their most popular models. The 2-4-0 rear end was later used in hillclimbing by various drivers including Roy Lane. A token F1 effort with Rothmans sponsorship was run in 1977 for Alex Ribeiro and Ian Scheckter, but nothing worthwhile was achieved. Yet, as the works were fading from F1 the 761, by virtue of being cheap, simple and readily available, became the tool of choice for privateers, notably Frank Williams who after his acrimonious split with Walter Wolf needed a car to get back into racing before his own vehicle was ready. Merzario later built his own unsuccessful F1 car based on his old 761, which he and Simon Hadfield attempted to develop into a ground effect car. This programme was completely unsuccessful. At the end of the 1977 season, the F1 team's assets and FOCA membership were sold to ATS (who had bought the Penske cars); Herd was retained by them as a consultant and was hence in the curious position of developing a development of his own 1975 car - and the 1978 ATS had some features reminiscent of contemporary March thinking. Mosley left the company to concentrate on FOCA matters. The F2 car had reached the end of a train of development that had started with the 732 and was becoming seriously uncompetitive; the works team abandoned the evolutionary 772 in favour of a smaller, neater car built around an old Formula Atlantic monocoque, the 772P. This was more than a match for the Martini opposition and formed the basis of the next year's dominant
