About the Lancia Delta S4 Stradale
The Lancia Delta S4 Stradale is the road-going homologation special for Lancia's most extreme Group B rally car. It famously pioneered twincharging, using an Abarth Volumex supercharger for low-end response and a KKK turbocharger for high-end power. Unlike the standard front-engine Delta, the S4 features a mid-mounted engine and a tubular spaceframe chassis with composite bodywork. While the rally version produced over 500 hp, the Stradale was detuned for road use and fitted with a luxurious Alcantara interior, though it remains a visceral, high-performance machine.
