Available power categories
The 2nd generation of OM 471 is available in five power stages from 310 to 390 kW. Vehicles equipped with this have an additional code M5B (2nd generation engine OM 471), apart from the actual engine code that describes the power stage.
Power categories |
OM 471 with code M3A | OM 471 with code M3B | OM 471 with code M3C | OM 471 with code M3D | OM 471 with code M3E | |
Output (kW) | 310 | 330 | 350 | 375 | 390 |
Output (horsepower) | 421 | 449 | 476 | 510 | 530 |
Torque (Nm) | 2100 | 2200 | 2300 | 2500 | 2600 |
Torque (Nm) vehicles with Top Torque* | 2300 | 2400 | 2500 | - | - |
* Vehicles with Top Torque have the additional code M0E (Torque increase, in 12th gear).
As in case of the 1st generation of OM 471, the basic power variants with 310, 330 and 350 kW are available with the special equipment "Top Torque". These vehicles possess a different data record, whereby a torque increase of approx. 200 Nm takes place when driving in 12th gear at 1100 rpm.

Power and torque curves with new characteristics in comparison with the 1st generation of OM 471
In comparison with 1st generation of OM 471, the maximum values of power and torque are unchanged. However, the power and torque curves rise considerably in the lower rpm range. In all available engine power stages, a torque of at least 2000 Nm is already applied at a speed of under 800 rpm. Similarly, at a rated speed of 1600 rpm reduced from 1800 rpm, 95 % of the maximum power is already achieved at approx. 1300 to 1400 rpm.
