The 2.0-litre engine, which debuted in E-Class passenger cars a few years ago, has been fitted to rear-wheel-drive versions of the Sprinter since the end of 2020 but is now scheduled to be added across the range.
The OM654 engine has a wide range of power and torque outputs tailored to the application.
In the case of the E-Class, its most advanced form includes an integrated starter/generator (ISG) adding an extra 15kW and 180Nm torque to an already impressive 195kW and 550Nm from the diesel core.
Tuned down for the Sprinter’s commercial roles, the ISG is dropped and engine output toned down to outputs between 84-140kW.
The engine includes a single water-cooled variable geometry turbo, 2700 bar injector pressure and 48v technology for the engine electrics.
According to Benz data, the new engine delivers better driving and comfort for Sprinter drivers.
It conforms to the Euro VI-E and Euro 6d emissions standard and reduces noise and vibration characteristics across the range via a combination of an aluminium housing with steel pistons, the stepped recess combustion process and the “NANOSLIDE” cylinder wall coating for reduced in-engine friction.
Together with dynamic multi-way exhaust gas recirculation and the in-engine exhaust gas after treatment, it delivers lower fuel consumption and lower emissions.
Because of its near-engine position, the exhaust gas after treatment works with little heat loss and in optimum conditions.
The engine will be available in four states of tune for the Sprinter, depending on the drive and body variant: 84kW, 110kW, 125kW and 140kW.
The engineers have also combined the engine with the nine-speed automatic transmission for the rear-wheel-drive Sprinter.
The six-speed manual remains unchanged in the range.
Deleting the ISG reflects the importance Mercedes-Benz places on its electric eSprinter, which is yet to be announced for the Australian market.
With the pure battery/electric version expanding its role in the product family and the accelerating acceptance of EVs for urban deliveries, there seems little point in adding complication to the model range when the ISG is only a stepping stone to EVs anyway.
With the eSprinter, the entire range of use in urban logistics can be covered locally emission-free.
The eCharging Planner advisory tool, for example, is part of the eVan ecosystem from Mercedes-Benz Vans and is designed to assist fleets in the transition to electric drive.
Next on the list for the van community is a modular design allowing the widest possible variation of body types to be added to an all-electric platform.
This modular concept consists of a front module for the high-voltage components, a module in the underbody for the high-voltage battery and a rear module with an electrically driven rear axle.
From mid-2023, the next-generation eSprinter will therefore offer considerably greater freedom in the development and design of various bodies.
