Efficiency. Fast forward to tomorrow.

Environmentally-compatible concepts.

BlueEFFICIENCY measures.

BlueEFFICIENCY measures are comprehensive vehicle optimisations that help save fuel and ease the burden on the environment. In the SLK, too, the most efficient engines are combined with the best features available, to keep fuel consumption to a minimum.

These include:

  • Aerodynamically shaped exterior mirror housings
  • Tyres with optimised rolling resistance
  • ECO start/stop function
  • ECO display and real-time fuel economy display
  • Ancillaries with energy-saving control logic and requirement-based activation (power steering pump)
  • Euro-6 emissions standard certification
  • Air conditioning compressor and fuel and oil pump
  • Alternator management (alternator switched off during tractive operation)
  • Engine technologies such as direct fuel injection and turbocharging
  • Optimised aerodynamics as the result of adjustable radiator shutters (available for the SLK 200)
  • Shift recommendation display for engines with manual transmission
