Cycle & Carriage - The SLK-Class Roadster

Environmentally compatible concepts

BlueEFFICIENCY from Mercedes-Benz stands for pioneering efficiency technology as well as innovative packages of measures based on optimising fuel consumption and emission levels.

BlueEFFICIENCY measures

The new SLK is equipped with a wealth of diverse BlueEFFICIENCY features and environment-friendly technologies, depending on the engine.

These are, for instance:

Aerodynamically shaped exterior mirror housings
Tyres with optimised rolling resistance
ECO start/stop function
Energy-saving control of auxiliary units with requirement-dependent action (power steering pump as well as fuel and oil pumps)
Alternator management (alternator switched off in traction mode)
Entire engine range certified as compliant with Euro 5 emissions class
Air conditioning compressor with on-demand control
Current fuel consumption indicator
Engine technologies such as direct injection and turbocharging
Optimised aerodynamics through the adjustable radiator shutters on the SLK 200 BlueEFFICIENCY
Shift point indicator for models with manual transmission

Efficiency technologies in the SLK Roadster

Direct injection, downsizing, increased compression and turbocharging in the new 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.
