1985 Lancia Delta S4 'Stradale'

This Delta S4 perfectly encapsulates the performance and excess of Group B rallying from the 1980s. Homologation requirements for Group B racing dictated that at least 200 road-legal versions of the iconic rally machine be built. Power was provided by the famed 1,759-cubic centimetre dual overhead cam four-cylinder engine, fitted with Weber Marelli IAW electronic fuel injection and dual-stepped Volumex supercharger and KKK turbocharger. The impressive 300bhp is sent to all four wheels via a five-speed manual gearbox.
