Inline-four engine
Homologation requirements for the World Rally Championship's Group B mandated Lancia to produce at minimum 200 verifiable road-going examples in order to compete with the 037. 207 037 Stradale (Italian for "road going/for the road") cars are known to have been produced from 1982 through 1984. This road-going 037 variant was equipped with an Abarth-developed DOHC 2.0-litre (1,995 cc) 16-valve Inline-four engine, mated to an Abarth Volumex Roots-type supercharger generating at 7,000 rpm. It was capable of pushing the car to over and to from a standstill in 5.8 seconds.
