Mercedes wrings more efficiency out of C-Class cars - Less weight, better aerodynamics are part of Blue Efficiency strategy
Mercedes has joined the ranks of manufacturers who have modded existing models to create "eco" models that boast improved efficiency.
In Merc's case, they took the bread and butter C200 with a standard combined rating of 38.6 mpg (imperial, I believe), and boosted it dramatically, to 46.1 mpg.
How?
Lowering weight, optimizing aerodynamics, cutting rolling resistance and improving driveline efficiency (including taller final drive ratio).
In doing so, they claim a Cd. of 0.25, not seen in a production car since the Honda Insight.
Aero tweaks will be familiar to ecomodders:
- partial grille block
- sealed joints around headlights
- tweaked side mirror housings
- full underbody panels
- lower ride height
- optimized wheel design
