The Lotus 38 was the first mid-engined racing car to win the Indianapolis 500, in 1965 by Jim Clark. It was an evolution of the previous Lotus Type 29 and Lotus Type 34 cars, but with an Aluminium monocoque, and was powered by the 4195cc quad-cam Ford V8 fuel injected engine as used in the 34, giving out around 500 bhp. The 38 was specially designed with offset suspension, with the car body situated asymmetrically between the wheels, offset to the left using suspension arms of unequal length. Although in theory this was better suited for the ovals.
