Famous drivers like Toivinen, Salonen, Rohrl, Alen, Bettega, Blomquist or Mouton drove these beasts on narrow tarmac roads as well as on blinds crests of Finland. However this class is banned since 1987, but you have chance to try these cars too, in your GeneRally.

BMW M1
The BMW M1 first competed at world championship level on the 1983 Tour of Corsica, the same event as Lancia's 037. Driven by Bernard Béguin, it produced 430Bhp from it's 3.5l 6cyl engine, and weighed 1150kg. The car was run by the ORECA team and sponsored by BMW & Motul. The car retired from the event but went on to score two second places, one on the 1983 Lyon-Charbonnieres rally and another at the Antibes rally. Main problems with the car were reliability and size. It was a good twenty cm wider than anything else competing at the time. The car never competed on a gravel event.
Ferrari 308 GTB
Most were built up by Michelotto of Padova who not only received authorisation from the factory but also got a good deal of back door assistance. Three of the Group B 308's were fitted with QV four-valve engines that produced 310bhp at 8000rpm, the first car (chassis 18869) using a 288bhp two-valve motor. The mechanical Kugelfischer fuel injection of Group 4 cars was changed to electronic Bosch K-Jetronic while, overall, the Group B variants came out some 30kg heavier because of their stock GRP and steel body panels. Just four were constructed by Michelotto over the winter of 1982/’83 to participate in various European Group B rally championships. The four Michelotto cars were raced by the Italian Rally team Pro Motor Sport. Chassis 22409 (pictured) was very successful in multiple major rallies, winning the Marca Trevigiani and Cittŕ de Bassano, driven by Giulio and Pasutti respectively, coming in second in both the Targa Florio and Isola d'Elba driven by Battistolli; and second again in the Príncipe de Asturias driven by Tognana. Chassis 18869 and 18971 both won 1st place in the Sicillian Rally Championship in '83 and '84 respectively. Chassis 18847 had 2nd place finish at the '84 Della Lana.
