Here is the translated text in English:

For the year 1993, the Challengers were updated and the model designation was appended with a C. The hydraulic and steering system was renewed: steering was now done using a hydraulic pump and hydraulic motors instead of a mechanical implementation. The brakes were now oil-bath type. The exhaust pipe and air intake were moved closer to the right pillar of the cab, and the fuel tank was slightly enlarged. To facilitate access to the cab, proper steps were added and the grab handles were renewed. The instrument panel was also completely new, and the trip computer was placed in a visible location at the top part of the dashboard.

The engines remained unchanged: the 65 C had an output of 285 hp and the 75 C had 325 hp. Ground pressure was specified as 0.39 bar, and for the 75 C equipped with wider tracks, 0.35 bar. In 1994, the Challenger 70 C was introduced, which had the engine of the 65 C and the transmission and undercarriage of the 75 C. Correspondingly, the 75 C was given a parallel model of the same power called the 85 C. The transmissions of the 75 C and 85 C were optimized for low speeds. In the later D series, the 85 C was replaced by the 370-horsepower 85 D, and similarly the 75 C was replaced by the 75 D. These versions were not brought to Europe, where the sales models remained the 65 C and 75 C until 1998.
