V-type engines are used in Mercedes OM442 vehicles. Their broad range of modifications, which span nearly the whole power range, set them apart. These engines feature eight cylinders with a diameter of up to 130 mm and two valves. At low revs, they attain high power ratings. They generate 408 horsepower (300 kW) at a rotational speed of 1800 rpm.
These units have a turbocharging system that enables them to have higher power levels with comparatively small cylinder volumes.
In addition to Mercedes-Benz vehicles, heavy trucks, road trains, agricultural vehicles, generators, and buses can all be equipped with this series of motors. This series of motors has the added advantage of lowering noise levels due to their low operating speed.

Daimler-Benz introduced new diesel engines for commercial vehicles of the 400 series with outputs ranging from 160 to 353 kW, including 6- and 8-cylinder V-engines, in addition to the models OM 442 A (260 kW) and OM 442 LA (320 kW), which were first introduced in 1985.
Both mechanical systems and the combustion system were created. A V6 diesel engine with direct injection and constant angular ignition timing for commercial vehicles was also introduced by Daimler-Benz at the same time.
