Lancia Delta S4 participated into the World Rally Championship in 1985 and 1986, until Group B cars were banned from competition by the FIA in 1987.
The S4 got full advantage of the Group B regulations, and featured a mid-mounted engine combined with supercharging and turbocharging system with and all-wheel drive for superior traction on loose surfaces.
That's why we are so excited that a rare Delta S4 is up for sale. The Italian seller stated the S4's mechanic and body parts had been restaurated. Judging from the images, the 550,000 USD (430.000 EUR) rally vehicle received an excellent care and looks in good condition.
