stresses of high speed off road driving. The 037 is notable in Group B as it retained the rear-wheel drive layout that was nearly universal for rally cars of the pre-Group B period; nearly all subsequent successful rally cars used four-wheel drive, making the 037 the last of its kind. Unlike its predecessor, the V6-powered Lancia Stratos HF, the first 037s had a 2.0-litre 4-cylinder supercharged engine. Based on the long stroke twin cam engine 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. The 037 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 but was increased to . The final Evolution 2 model's engine generated due to a displacement increase to .
