Goodwood Festival of Speed FOS 2011, Forest rally stage start with a 1985 Lancia 037 Group B rally car. Next: Audi Quattro S1. The Lancia Rally 037 (also known as the Lancia Abarth #037) was a mid-engine rally car built by Lancia in the early 1980s purely for the FIA Group B World Rally Championship. Driven by Markku Alén, Attilio Bettega, and Walter Röhrl, the car won Lancia the manufacturers' world championship in the 1983 season. It is the last rear-wheel drive car to win the WRC. Unlike its predecessor, the V6-powered Lancia Stratos, the first 037s had a 2.0 liter 4-cylinder supercharged engine. Based on the long stroke twin cam which powered earlier Fiat Abarth 131 rally cars, the four valve head was carried over from the 131 Abarth but the original two carburetors were replaced by a single large Weber carburetor in early models and later with fuel injection. It features a ZF transaxle. Lancia also chose a supercharger over a turbocharger to eliminate turbo lag and improve throttle response. Initially power was quoted at 265 hp (198 kW) but with the introduction of the Evolution 1 model power jumped to 300 with the help of water injection. The final Evolution 2 model produced 325 hp (242 kW) thanks to a displacement increase to 2111 cc.
