The Lancia Delta S4 Strada was conceived in 1983, before going
into production in 1985. Only 200 S4 Strada's were produced
purposes to allow the mighty S4 to compete in the legendary
Group B Rally series.
The S4 name is an abbreviation of supercharged and 4, for four-wheel-drive.
The 1759 cc 4 cylinder engine of the Lancia Delta S4 Strada
was force-fed by both a supercharger and a turbocharger, this
meant the cars immense power was available throughout a much
wider rev range. In road going form the S4 Strada put out around
250 horsepower, but by 1986 some of the race versions were achieving
upwards of 550 horsepower.
The 4-wheel drive transmission of the Lancia Delta S4 Strada
could be adjusted from 75/25 rear/forward bias, to 60/40, depending
on conditions and driver preferences.
