A heavily modified Skoda Garde (often known as the Czechoslovakian Porsche) intended to participate in the World Rally Championship under one of Group B’s lower classes. There were two Skodas modified specifically for rallying - the a bit more well-known 130LR and this, which only stayed a prototype.
The 160RS wasn’t a factory modification - a coachbuilder called Metalex took charge of building it instead. Hence the Sport quattro styled widebody and the engine from a Lada VFTS.
The Slavia 1600RX, as it’d be known ingame would have a rating somewhere in high class D with an acceleration focus, slightly above average handling and low top speed, priced at around 30M
