1986 Lancia Delta S4

The Lancia Delta S4, introduced in 1986, is a high-performance rally car that was manufactured by the Italian automobile manufacturer Lancia. The car was built to comply with the then-existing Group B regulations of the World Rally Championship (WRC). The Delta S4 was a purpose-built rally car with innovative technology designed to provide unparalleled performance on the rally tracks.

One of the most significant aspects of the Lancia Delta S4 was its powertrain. The car was powered by a 1.8-liter four-cylinder engine that used both a supercharger and a turbocharger. The engine produced an amazing 480 horsepower and 361 lb-ft of torque. The power was transmitted to all four wheels through a full-time all-wheel-drive system that provided exceptional traction on any terrain.

The suspension system of the Lancia Delta S4 was equally innovative. The car featured double wishbone suspension on all four wheels, with adjustable dampers that enabled the driver to fine-tune the suspension to suit any driving condition. The car also had adjustable ride height and adjustable anti-roll bars, which made it one of the most adaptable rally cars of its time.

The Delta S4 was constructed using a tubular steel space frame chassis, with a fiberglass body weighing only 980 kg. The weight distribution of the car was 50:50, which provided exceptional balance and handling. The car's aerodynamics were also a significant factor in its performance, with an adjustable rear wing and front splitter that provided ample downforce at high speeds.

The car's braking system was equally impressive. The Delta S4 had four-wheel disc brakes with hydraulic handbrake controls at the rear, which provided excellent stopping power. The car also had an adjustable brake bias, which allowed the driver to tailor the brake performance to their liking.

Inside the car, the driver was treated to a lightweight composite racing seat and a full roll cage. The car's dashboard was minimalistic, with only essential gauges and switches, reflecting the Delta S4's focus on driver-focused performance.

In conclusion, the Lancia Delta S4 was a highly innovative rally car that was ahead of its time. Its technological innovations and exceptional performance make it a coveted collector's item today. The combination of a supercharged and turbocharged engine, all-wheel drive, adaptable suspension, lightweight construction, and exceptional braking performance made the Delta S4 a true legend in the world of rallying.
