BlueEFFICIENCY measures

The BlueEFFICIENCY measures are comprehensive vehicle optimisations which help save fuel and ease the burden on the environment. The SLK also combines the most efficient engines with the optimum aerodynamics and energy management features available to keep fuel consumption to a minimum.

These include:

  • Aerodynamically shaped exterior mirror housing
  • Tyres with optimised rolling resistance
  • ECO start/stop function
  • ECO display and current consumption indicator
  • Energy-saving on-demand ancillary components (power steering pump, air conditioning compressor, fuel and oil pumps)
  • Alternator management (alternator switched off in traction mode)
  • Entire engine range certified as Euro 5 emissions class
  • Engine technologies such as direct injection and turbo-charging
  • Optimised aerodynamics through adjustable radiator shutter[1]
  • Shift point indicator for models with manual transmission

Efficiency technologies in the SLK Roadster

Direct injection, downsizing, increased compression and turbocharging in the optimised engine generation enable top torque, output and noise reduction figures. Innovative engine technology makes it possible to significantly reduce emissions and fuel consumption compared with previous models.

Environmental certificate

Mercedes-Benz is the only automotive brand in the world to have received an ISO-standard Environmental Certificate. For this certification, the vehicle models have to meet strict requirements and undergo stringent controls in their development, production and recycling. Our goal is to make environmental protection objectively measurable and to make it possible for you as the driver to experience it concretely.
