Before Group B was cancelled, Bruno Saby managed to get much rallying experience with the top Peugeot Talbot Sport WRC team, winning the 1986 Tour de Corse. Afterwards, among other series, he participated in the 1988 French Rallycross Championship driving a Lancia Delta S4.
Albeit it was a very costly car, the Delta S4 was one of the most coveted for rallycross since it combined both supercharging and turbocharging (resulting in very little lag and more power down in the low rpm range). However, the car was reportedly very twitchy and difficult to drive on bumpy terrain. As such, many Delta S4 rallycross privateers tried adding lots of aerodynamic aids to the car. Albeit Saby’s S4 was officially rated at 450 HP, other teams reportedly used up to 600 HP, and in the later rallycross horsepower wars it was rumored that some S4s had over 800 HP. It is one of the rarer Group B cars to participate in the European Rallycross Championship.
