Biturbo S II

Biturbo S II - 1985 to 1986

The second series of the Biturbo S was introduced in 1985, with some minor upgrades, and was therefore known as the Biturbo S II.

A slight increase in power output improved the acceleration figures, whilst the more voluminous fuel tank allowed for a greater travel autonomy. 1038 cars were produced, combining the 1st and 2nd series.
