Description The Lancia Delta S4 is a Group B rally car from the Italian car company Lancia. The Delta S4 competed in the World Rally Championship in 1985 and 1986, until Group B cars were banned from competition by the FIA. The car replaced and was an evolution of the Lancia 037. The S4 took full advantage of the Group B regulations, and featured a mid-mounted engine and all-wheel drive for superior traction on loose surfaces. The car’s 1,759.3 cc four-cylinder engine combined supercharging and turbocharging to reduce turbo lag at low engine speeds. Officially, the car produced 480 horsepower but some sources claim that the Delta S4 produced about 560 horsepower. In 1985, Lancia engineers tested an S4 engine under extreme conditions, reaching 5 bars boost, developing around 1000 horsepower. An engine capacity multiple of 1.4 was applied to forced induction engines by the FIA and the choice of 1,759 cc put the S4 in the under 2,500 cc class, which allowed for a minimum weight of 890 kg (1,962 lb). The combined super/turbocharger system (often referred to as twincharging) was a development of the 037 engine that produced 350 hp with a supercharger only. 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. This car originally was a “Stradale” version, used in period as a recce car by the Grifone Esso team who started to build the car to Group B specification in the 1986 season. However, as we know, the ruling changed in that year and the Group B cars were banned from competition by the FIA. The car was partially dismounted and some years ago, this absolutely fantastic example of this iconic Group B Rally car of the 1980s was restored by an Italian collector in 2015: the chassis was re-built out of CrMo steel tubes and aluminium alloy for the crash structures and enforced by the same parts of the official manufacturer used in period; it was covered by carbon Kevlar body panels instead of epoxy and fiberglass. Like the rally car, these cars had mid mounted engine of 1.8-litre engine, equipped with Weber-Marelli IAW integrated electronic ignition and fuel injection, a supercharger, a turbocharger and two intercoolers. This car with the gearbox and differential of a Group B car and the engine has the same preparation as the last evolution with power of more than 500 hp! It is now restored to include period Martini racing livery. The car has participated in important events since in Europe to include the Rally Legend, Valpantena, Rally Monza to name a few. Presented in excellent condition throughout, this is truly stunning and represents the very best of the Group B rally cars of that era. A great investment opportunity and a thrill to drive. This is an opportunity not to be missed and is surely one of the best to come to the market.The Lancia Delta S4 is a Group B rally car from the Italian car company Lancia.
