Mercedes BlueEfficiency Models
The number of fuel-efficient cars has started to multiply day by day with manufacturers announcing new models one after another. Even those manufacturers such as Mercedes-Benz has joined in with the introduction of the C-class BlueEfficiency. Models were shown at the Geneva Show.
Modifications mainly concern reduced weight compared to the standard version which cut fuel consumption by 15 percent. BLOG WIRED NETWORK reports the exact changes.
Weight reduction, compared with the standard versions of the C-class, ranges from 42 to 71 pounds. Savings come primarily from the use of a new lightweight laminated windshield, lighter insulation material, and aerodynamically optimized forged aluminum wheels.
Wind-cheating modifications, including a ride height lowered by 15 millimeters, a smooth belly pan, a variable radiator shutter that manages the amount of air flowing through the grille, resculpted mirror housings, and sealed gaps between the bumper, headlamps, and hood, lower the car’s drag coefficient by 7 percent, from an already-fine 0.27 to 0.25. New tires from Michelin lower rolling resistance by 17 percent.
Under the BlueEfficiency title go the C200 CDI, C180 Kompressor and C350 CGI and it’s possible that other Mercedes models might join them. This is another example that Mercedes is able to significantly cut the fuel consumption just by playing with weight and improving aerodynamic factors rather than touching the engine.
