The engines used are:

A: Steyr Diesel WD612 A, 195 Ps (220Ps-JIS) at 2,400 rpm, 650 Nm of torque at 1,300 rpm

The engine is assembled with the chassis in Purwakarta, and combined it with the ZF transmission. This German-imported transmission is used for the Perkasa Bus series A (front) and B (rear). The transmission used ZF6s-680 which has a short-ratio character, and for an engine that uses a Turbo Intercooler, Perkasa paired it with the ZF6S-90 which has a longer gear ratio.

The wheelbase is 5,800 mm (A, front engine) and 6,000 mm (B), almost the same as the wheelbase of the Hino RG, equipped with the American-manufactured Eaton front-rear axle. In the specifications, the front axle can withstand loads of 7,725 kg and for the rear can withstand up to 10.5 tons.
