Mercedes launches C-Class Blue Efficiency
For the C-Class Blue Efficiency, Mercedes has installed lighter glass (1.2 kg less) and lightweight alloys, as well as using tires that have 17 percent less rolling resistance. The car was also lowered and got a revised engine bay, closed underbody and redesigned mirrors for slicker aerodynamics. These changes reduce overall resistance by seven percent.
The C180 Kompressor had its engine size reduced from 1.8 to 1.6 liters while keeping its power and torque figures, 156 HP and 230 Nm (170 lbft), respectively. The C200 CDI got no significant improvements, and neither of the two versions got the Stop/Start feature. However, fuel consumption figures are already pretty good: 6.5 l/100 km (36 mpg U.S.), and 5.1 l/100 km (46 mpg) for the C200 CDI. Even without out any serious changes to the C200 CDI, these are 0.9 and 0.6 liters lower than the previous most economical versions, respectively.
