In 2005 Mercedes-Benz introduced newly developed V6 engines that opened up a brand-new chapter in its long and successful history as a maker of diesel engines. These six-cylinder powerplants combine all of the current and future-oriented technologies developed for diesel engines - from the mechanical systems and thermodynamics to the flow dynamics, electronic engine management and exhaust gas purification. That guarantees top values in performance and torque characteristics, economy, exhaust emissions and smooth operation. In the future, the V6 diesel engine in the R-Class will be available in two output ratings: 140 kW/190 hp in the new R 280 CDI 4MATIC and 165 kW/224 hp in the R 320 CDI 4MATIC.


The most striking characteristics of the new Mercedes diesel engines can be summed up as follows:


  • Six cylinders in a V-shaped configuration
  • Aluminium crankcase with grey cast iron cylinder liners
  • Third-generation common-rail technology with piezo injectors
  • Four-valve technology with two camshafts per cylinder bank
  • Exhaust-gas turbocharger with electrically adjustable turbine vanes
  • Peak combustion pressure up to 180 bar
  • Exhaust gas recirculation with electrically regulated valve
  • Electrically regulated throttling of the intake air
  • Swirl control through electrically controlled intake port shut-off
  • Quick-start glow-plug


First aluminium V6 diesel engine


More output, higher torque and lower exhaust emissions — these were the main goals of the teams that developed the V6 diesel engine, and they used a number of different strategies to achieve these goals. One example is the engine’s lightweight engineering.
