Side view of a Cosworth DFV engine powering an Arrows A3 formula One Car, previously driven by Jochen Mass
The Arrows A3 was a Formula One car which the Arrows team used to compete in the 1980 and 1981 Formula One seasons. After the failure of the A2 in the 1979 Formula One season, the A3 was a very conventional design. The A3 featured a short wheelbase and conventional front nose and rear wing. The only aerodynamic novelty was a gearbox enclosure to reduce drag. The DFV is an internal combustion engine that was originally produced by Cosworth for Formula One motor racing. The name was an abbreviation of Double Four Valve, the engine being a V8 development of the earlier four-cylinder FVA, which had four valves per cylinder.[1] Its development in 1967 for Colin Chapman's Team Lotus was sponsored by Ford. For many years it was the dominant engine in Formula One, and it was also used in other categories, including CART, Formula 3000 and Sportscar racing. The engine was a 90°, 2,993 cc V8, with bore & stroke of x mm ( x in) producing over 400 bhp (408 bhp at 9,000 rpm, 270 ft·lbf (370 N·m) torque at 7,000 rpm was quoted) from the start, reaching over 500 bhp (510 bhp at 11,200 rpm was quoted) by the end of its Formula 1 career. The 1983 DFY variant had a revised bore and stroke of 90 x 59 mm ( x in) giving 2,993 cc and 520–530 bhp at 11,000 rpm, 280 ft·lbf (380 N·m) torque at 8,500 The project was revealed by Hayes in a PR launch in Detroit at the end of 1965, but the engine was not ready until the third race of the 1967 season, on the 4 June at Zandvoort. Its debut proved electric. Graham Hill, who was in the team at the specific request of Ford and Hayes, put his DFV-powered Lotus 49 on pole position by half a second and led for the first 10 laps but was then sidelined by a broken gear in the camshaft drive. Team-mate Jim Clark moved up through the field in his identical car and came home to win.
