FSO Polonez 2000 Group IV
The racing history of the Polonez begins in 1978. It first competed at multiple sports events as a demonstration car until it was granted homologation into Group IV rallying on January 1, 1979. The body of the car was slimmed down and inside was a roll cage barely meeting the minimum approval. The car did not have side skirts, the body panels were made of metal, and the hood was stripped of its reinforcements.. Corrosion protection covers were used instead of extensions and the car had Cromodora wheels and mirrors . A Cibie battery pack was attached to the front. The car had bayflex bumpers with holes cut out to reduce the weight of the vehicle. It was fitted with additional rallying equipment to meet the regulations. The vehicle had a fuel tank with a capacity of 72 liters. The car was driven on a modified 2.0 DOHC engine that had four Weber carburetors, one for each cylinder or mechanical injection. It achieved 170/185 hp. The car used a metal clutch, a Colotti claw gearbox in five gear ratios, and limited slip rear axle. The rear axle was strengthened with aWalter Wolf Racing

The chrome accessories and rubber dart from the front bonnet were removed from the Polonez. This Polonez had about 210 horsepower.
