. An important advantage is the removable wet cylinder liners which will assist with easier maintenance and lower costs. Its Multi Turbo System (MTS) turbine with variable vane geometry, is electronically controlled. This helps achieve faster responses, better performance, and better thermal efficiency. This also works as part of the engine brake retarder in the exhaust system. The water-cooled exhaust gas recirculation (EGR) system, coupled with the

, reutilises part of the exhaust gasses, producing combustion at lower temperatures with less discharge rates. It includes a new engine brake system, the Dual Power Brake (DPB) fed into the cylinder head, is electronically integrated into the turbocharger. It is claimed that the advantages are: increasing the operational average speed, the brake force, safety, retaking with fuel reduction, and speed on downward slopes. This means less gear shifts, lower maintenance costs, and helps improve the service life of the brakes and tyres.

The engine output is routed through a variety of transmissions. One option is the ZF 16S 1685 TD 16-speed manual synchromesh transmission. This latest ZF box is lighter than existing models, due to its all- aluminium alloy casings. It has a torque handling capacity of . The 6x2 variants use a Meritor MS 23-185 tractive rear axle, and this has a maximum capacity of 60 tons. It includes a series differential locking system when used on the VW 25.370 tractor unit. The 6x2 variants also have the facility for partial or total lifting of the third axle, which helps achieve better traction, particularly on slopes. This Extra Traction Device (ETD) ensures part of the third axle load, during partial lifting, is transferred to the tractive axle. 6x4 variants utilise Meritor MD/MR 25-168 tractive rear axles, and are located via
