The Lancia Rally (also known as the Lancia Abarth #037) is a mid-engine race car built by Lancia in the early 1980s purely for FIA Group B World Rally Championship. Unlike its predecessor, the V6-powered Lancia Stratos, it had a 2.0litre 4-cylinder supercharged engine developing about 250bhp. The power output increased to 325bhp with the 2.1 litre 'Evolution' version introduced in 1984.
This car is very loosely based on its more common road-going counterpart, the Lancia Monte Carlo (also known as Scorpion in the US and Canadian markets). As for the 037 part of the name, this was a project carried out by Abarth (another car maker under FIAT's corporate wing) whose project number was 37.
Despite its lack of 4WD, which limited its competitiveness on gravel events, the 037 took Lancia to World Championship honours in 1983 behind the efforts of Walter Röhrl. Its final WRC result was at the '86 Safari rally with Markku Alen in third position.
