Engines are faced with the challenge of yielding top performance in very difficult conditions in the Middle East. Mercedes-Benz's V6 and V8 engines have routinely been accomplishing that task for many years. Because they are eminently capable of generating the power required, but are distinctly thrifty when it comes to fuel consumption. With power outputs ranging from 310 to 480 hp, they are equipped for every transport task.

The V6 engines with a displacement of 11.9 litres are available in three performance categories: 230 kW / 313 hp, 260 kW / 354 hp and 290 kW / 394 hp. Equipped with an exhaust turbocharger with charge-air intercooling, they already achieve their maximum torque at 1080 rpm.

This yields an optimum power characteristic that is very fuel-efficient. The 6-cylinder engines with electronic control have been on the market for a great many years and are used predominantly for short-distance transport tasks (construction sites, deliveries, refuse collection), but the 394 hp version is also used for long-distance traffic.

The basic version for V6/V8 engines is an all-synchromesh overdrive gearbox with 16 forward and two revearse gears. It comprises of a 4-speed basic gearbox, a front-mounted (split) section and rear-mounted (range) section. It is possible to change gear by means of a hydraulic gearbox shift system, with the Telligent shift system or with the Telligent automatic shift system. Two versions with different gearbox spacing are available: G 210: 14.2-0.83; G 240: 11.7-0.69.
