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 midship-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.

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. In road tune the 1.8 produced 250 PS  at 6750 rpm and 291 N·m  at 4500 rpm. The “Stradale” kept a three differential four-wheel-drive system; the centre differential sent 30% of the engine torque to the front open differential, and 70% to the rear limited slip one

This absolutely fantastic example of this iconic Group B Rally car of the 1980s was totally restored by an Italian collector in 2015. This is a Stradale version of this car used in period as a recce car by the Grifone Esso team who built 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. 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 Show 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.

Dieses absolut fantastische Beispiel eines ikonischen Gruppe B Rennautos der 80er, wurde 2015 von einem italienischen Sammler restauriert. Dies ist eine Stradale-Version des Wagens und es wurde vom Grifone Esso Team genutzt, welche das Auto 1986 zur Gruppe B Spezifizierung aufgewertet haben. Seit der Restaurierung trägt es die Martini Racing Optik.
Das Auto hat seidem an wichtigen Rennen europaweit teilgenommen, wie z.B. Rally Legend, Valpantena und Rally Monza Show. Präsentiert in rundum ausgezeichnetem Zustand, ist dieses Stück wahrlich atemberaubend und vertritt das beste der Gruppe B Rennautos seiner Ära. Eine tolle Gelegenheit einer Investition und purer Nervenkitzel zum fahren. Sie sollten es sich nicht entgehen lassen, diese Gelegenheit ist eine der Besten, die es auf dem Markt geben wird.
