In 1992 a new half-bonneted series WPK was presented. It was maximally unified with the bonneted series TPK. The range consists of three basic models WPK-4.40 (4×4), WPK-6.55 (6×6) and WPK-8.70 (8×8) with a payload from 4 to 8 tonnes. The trucks are equipped with Perkins Phaser turbocharged diesel engine with power of 180-210 hp and 6-speed transmission. The cabin could be with open top or closed type. The other feature of the new trucks is that they could be transported by C-130 and C-160.
