Between October 1985 and 1986 Lancia built 200 examples of a road-going version of the Delta S4, officially named Lancia Delta S4 but widely known as ‘Stradale’, for the purpose of homologation in Group B. In Italy the car was priced at about 100 million Lire: five times the price of the most expensive Delta of the time, the HF Turbo.
The Stradale’s chassis was a space frame, similarly to the racing cars, built out of CrMo steel tubes and aluminium alloy for the crash structures; it was covered by epoxy and fiberglass body panels. Like the rally car these cars mounted in a midships position a 1.8-litre engine, equipped with Weber-Marelli IAW integrated electronic ignition and fuel injection, a supercharger, a turbocharger and two intercoolers.
