This purpose built Lanica S4 Delta coupe was first used as a factory test car for snow rallying in preparation for the World Rally Championship events. It was designed to compete in the Group B competition class for the World Rally Championship. When introduced, it was revealed in the popular Martini color scheme featuring a white body with blue and red stripes. It has extremely well documented and interesting history, as it was used for snow tests and raced extensively in the Italian hill climb circuit. It won the Italian hill climb Championship in 1987 before being retired in 1988.
This Group B rally car is powered by a 1759.3cc four-cylinder engine with combined supercharging and turbocharging that is rated an impressive 480 horsepower from the factory, but in the real world it is closer to 560 horsepower. The Group B era lasted from 1983 until it was banned in 1986. 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.' Lancia claimed the car could reach top speed of 140 mph and accelerate from standstill to 60 mph in six seconds. In contrast to its bare bones racing sisters, the S4 Stradale featured an Alcantara-upholstered interior, sound deadening, a suede steering wheel, and was equipped with power steering, trip computer and air conditioning.
The mid-ship mounted engine allowed for greater balance and improved handling. It also features full time all-wheel drive. Extensive use of high tech super lightweight materials such as Kevlar and carbon fiber were used wherever possible to keep the overall car weight to a minimum. This car also exhibits numerous advanced features with several spoilers and winglets to assist in keeping it on the ground as it rushes through the course.

FIA Group B World Rally Championship racing, from 1982 to 1986, had few restrictions and rapidly evolved thanks to Space Age exotic materials, turbo-boosted horsepower, and technical ingenuity. The cars speed and performance progressed so quickly, that safety precautions were unable to keep up, and the number of accidents quickly rose, causing the sanctioning body to disestablish the class.
The rally cars that raced during this period are some of the most memorable. Lancia had their Fulvia HF, Stratos, and 037, While Audi had their Quattro - the first rally car to feature four-wheel drive. The Quattro the AWD's potential by winning the championship in 1982 and 1984. Lancia's response was the Delta S4 in 1985, which featured a tubular space frame, fully adjustable suspension, lightweight composite bodywork, a transmission driving all four wheels, and a diminutive, twin-charged – turbo and supercharged – 1.8-liter four-cylinder engine that could output over 500 bhp. Zero-to-sixty was accomplished in about two seconds. The Delta S4's first competitive outing was at the 1985 RAC Rally which it won. Markku Alen would finish the following year in second-place in the driver's championship.
Homologation requirements for Group B racing required at least 200 'Stradale' - or street - versions of the model to be built.
This particular example is a Lancia Delta S4 Stradale that had previously been finished in Verde York. It is now finished in its original factory red, with Beige Alcantra interior. It has power steering, a trip computer, carpeting, and air-conditioning. Power is from a 1759cc dual overhead cam four-cylinder unit fitted with a Weber Marelli IAW Electronic Fuel Injection system and Duel Stepped Volumex Supercharger and KKK Turbocharger. The 300 horsepower produced by the engine is sent to all four-wheels via a five-speed manual gearbox.
This car has been given a comprehensive restoration that brought it up to Potenziato specification. It has an upgraded clutch, engine software, exhaust, and wider rear wheels and tires.By Daniel Vaughan | Oct 2016
