Starting in March 1977, a Rallye kit was offered to sporty customers who intended to use the Peugeot 104 ZS in competition. Thanks to the various modifications approved in Group 2, the car could count on about eighty horsepower, which allowed a top speed of around 195 km / h. The 104 ZS was also currently used in Group 1 with fewer modifications than the Group 2 configuration.
