The 370 develops 1900Nm of torque. Managed by an EMS S8 engine management system, it doesn't feature many elements of the 410, apart from the clutch and high-pressure pump, which are common to all 13L Streamlines. Even so, we can optimize the vehicle after engine reprogramming.

The 410 develops 2150Nm of torque. Managed by the EMS S8 engine ECU, it shares only the clutch with the 370, the K432 62. Its twin is the 450 DC13 147, except for the clutch. They don't have an EGR valve, but they do have FAP and SCR. Injectors, Turbo and HP pump are shared with the 450 (DC13 147).

The 450 develops 2350Nm of torque, managed by an EMS S8 engine control unit. It features the same configuration as the 410, with the exception of the clutch, which can handle slightly more torque than the 410. It also features FAP and AdBlue, and no EGR valve. HP pump, injectors and turbo are common parts.

The 450 DC13 124 also develops 2350Nm. In fact, it's the R490 Euro 6's counterpart. All 490 parts are also present on the 450 DC13 124. Injectors, turbo, HP pump, EGR FAP SCR system, gearbox and clutch are all identical, providing a significant gain in power and torque after optimization.

The R440 Euro 6 develops 2300Nm of torque and is derived from the EEV version. It is in fact totally identical to the R480 DC13 110 Euro 6. Optimization therefore delivers a significant gain in torque and engine power without any gaps. All fuel injection and supply components are shared with the R480, as are the turbo and transmission. Both are equipped with K432 48 clutch discs.

The R480 Euro 6 develops 2500Nm of torque, managed by an EMS S8 gearbox. It features the same peripherals as the 440 in terms of transmission, fuel injection and fuel supply. The supercharger system is also the same as the 440, with the same turbo. Engine management, on the other hand, is different, enabling us to obtain more than 440, i.e. 480 hp, while the rest is identical.

The 490 develops 2550Nm of torque, managed by an EMS S8 motor unit. It features the same parts mounted on the 450 DC13 124. Only the engine management program can be used to unbridle power on this model, but 450 or 490, the end result will be the same. Optimized power and torque significantly improve driving pleasure at low engine speeds.
