New Modular Engine Family from Mercedes-Benz is Cleaner and More Powerful

The new engine family from Mercedes-Benz sets new standards in terms of power output, refinement and efficiency. The new family of petrol and diesel engines, with 4, 6 and 8 cylinders, is of modular design. The key features of the new family are a standard cylinder spacing of 90 mm and identical interfaces to the vehicle, which makes for modern, flexible production, among other things.

The scaling of state-of-the-art technologies and electrification options from 12 V to 48 V to high-voltage plug-in applications makes it possible to configure the appropriate powertrain for every vehicle. Mercedes-Benz is investing a total of around 3 billion euros in its strategic engine initiative. The new family of engines was launched in 2016 with the four-cylinder diesel OM 654 and will be systematically extended with the following engines in 2017:

  • six-cylinder in-line petrol engine M 256
  • four-cylinder in-line petrol engine M 264
  • V8 petrol engine M 176
  • six-cylinder in-line diesel engine OM 656


  • A host of innovations will go into series production in 2017:
  • electric auxiliary compressor eZV
  • Integrated Starter-Alternator ISG
  • belt-driven starter-alternator BSA
  • 48 V electrical system
  • cylinder shutoff
  • Particulate filters for petrol engines
  • near-engine exhaust system
  • 2500 bar diesel injection
  • CAMTRONIC in diesel engine (OM 656), V8 biturbo petrol engine (M 176) and four-cylinder petrol engine (M 264)


  • In 2017, the new S-Class will be the first Mercedes-Benz vehicle to be powered by the new engines.
  • The new engines are tuned to the vehicles on state-of-the-art test rigs at the new Powertrain Integration Centre (AIZ) in Sindelfingen, where new technologies and powertrains are continuously further developed for the future.
