BlueEFFICIENCY: extremely fuel efficient overall

Enlarge

In striving to achieve zero-emission mobility, Mercedes-Benz offers a wide variety of technologies: optimized combustion engines, hybrid vehicles, electric drives with fuel cells or even purely electric-driven vehicles. The BlueEFFICIENCY technologies are also a package of measures which can further reduce energy consumption and therefore CO2 emissions for all passenger car and van models. Whether it’s the automatic start/stop function, electrically assisted power steering, low-rolling-resistance tires, aerodynamic refinements, intelligent lightweight engineering, gear-shifting and fuel consumption display or engines with lower displacement and turbochargers: on balance, vehicles benefiting from a holistic optimization approach use so little fuel that drivers feel the benefit in their wallets. In a nutshell: at Mercedes-Benz, BlueEFFICIENCY stands for the concept of efficient mobility.

Enlarge	The most economical S-Class ever Innovative technology, such as on-demand power steering, automatic transmission with standstill decoupling and tires with lower rolling resistance, has helped to make the new S 320 CDI BlueEFFICIENCY one of the most frugal executive sedans.
Enlarge	Safe, comfortable, efficient – the new E Class sets standards in efficiency and environmental compatibility with up to 23 percent lower fuel consumption compared with its predecessor. In recognition of their BlueEFFICIENCY badge, two-thirds of the new E-Class models boast fuel consumptions from as low as 5.3 liters per 100 kilometers and CO2 emission levels from 139 grams per kilometer.
Enlarge	The C-Class BlueEFFICIENCY models More powerful, more economical and cleaner: the C 180 CDI and C 200 CDI have been available since the spring of 2008 as BlueEFFICIENCY variants. The four-cylinder diesel engines use up to twelve percent less fuel.
Enlarge	Doubling environmental efficiency with NGT The B 170 NGT BlueEFFICIENCY can run on premium grade gasoline or natural gas. When operating in natural gas mode, CO2 emissions are reduced by more than 20 percent compared with gasoline mode.
Enlarge	Saving with the start/stop function The A and B-Class BlueEFFICIENCY models feature an ECO start/stop function which reduces fuel consumption. The engine automatically switches off when waiting at red lights – and then comes back on when you are ready to drive off.
