Lancia Rally 037 I (Tipo 151) gallery (1982–1984)
The Lancia Rally 037 was a mid-engine Group B homologation sports car that became the final rear-wheel-drive machine to conquer the World Rally Championship.
The Lancia Rally 037 (factory project code Tipo 151) was developed jointly by Lancia, Abarth, and Pininfarina to compete in FIA Group B rallying, with road-going homologation versions sold as the 037 Stradale between 1982 and 1984. The chassis architecture utilized the central steel passenger cell of the mid-engine Lancia Beta Montecarlo, complemented by bespoke front and rear tubular steel subframes designed for quick mechanical servicing and extreme rigidity. The two-door coupé bodywork was constructed from lightweight fiberglass reinforced with Kevlar panels, keeping curb weight down to around 1,170 kg for the Stradale and under 980 kg for competition cars. Mounted longitudinally behind the cockpit was a 2.0-liter (1,995 cc) inline-four DOHC 16-valve engine derived from the Fiat twin-cam unit, supercharged via a Roots-type Abarth Volumex supercharger and Weber carburetion. The road Stradale produced 205 hp, while the competition Evolution 1 and Evolution 2 variants delivered between 310 hp and 350 hp (with Evo 2 receiving a displacement bump to 2.1 liters and water injection). Power was delivered exclusively to the rear wheels via a five-speed ZF dog-leg manual transaxle and a mechanical limited-slip differential. The 037 was sold primarily to European privateers and enthusiasts to satisfy the 200-unit minimum requirement, forever etching its name in history as the last rear-wheel-drive car to win the World Rally Championship in 1983.
