Lancia Delta I S4 “Stradale”
Description
The Lancia Delta S4 “Stradale” is the production version of the Delta S4 Group B rally car that competed in the World Rally Championship in 1985 and 1986.
The homologation special was only produced in 200 street legal examples, with a space frame chassis made of CrMo steel tubes and aluminium alloy, and a body made of fiberglass and epoxy. The road going version was fitted with a 1,759 cc engine, producing 250hp (184 kW) at 6750 rpm and 291 Nm (215 lb⋅ft) at 4500 rpm, combined with a 5 speed manual gearbox. The dual overhead cam four-cylinder engine featured a Weber Marelli IAW electronic fuel injection system, a dual-stepped Volumex supercharger and a KKK turbocharger. Like the race car, the “Stradale” version was all wheel drive, with a center differential sending 30% of the torque to the front open differential and 70% to the rear limited slip differential. As a result, the Delta S4 “Stradale” could accelerate from 0-100 km/h in 6 seconds and could reach a top speed of 225 km/h (140 mph).
Visually, the Delta S4 “Stradale” was very similar to the Group B rally car with a totally different structure and redesigned body panels compared to the regular Delta due to the mid-engine layout. The cabin was surprisingly luxurious, with Alcantara upholstery, a suede steering wheel, sound deadening material, trip computer and air conditioning.
