Other BlueEFFICIENCY measures include newly developed tyres with up to 17 per cent lower rolling resistance, need-related and therefore energy-

saving control of the alternator, fuel pump, air conditioning compressor and power steering, and the ECO start/stop function (from late summer 2009)

which switches the engine of the new E 200 CGI off when idling. Displays in the speedometer inform the driver how much fuel is being consumed

(mpg), and when they should shift to the next higher gear in the interests of an economical and environmentally conscious driving style.

Engines: new CDI-four-cylinder units with a fuel consumption of 53.3 mpg and 139 grams of CO<SUB>2</SUB> per kilometre

With three completely newly developed four-cylinder engines, the E-Class also remains one generation ahead where diesel technology is concerned.

These engines feature latest-generation common-rail direct injection, fast piezo-electric injectors, improved exhaust gas recirculation and an innovative

twin turbocharger, making for improved responsiveness and good performance characteristics. To express this in figures, the E 250 CDI with 204 hp

and 500 Nm sees an improvement of 60 Nm of torque over the previous E 280 CDI V6 diesel engine, but uses around 23 per cent less fuel returning

53.3 mpg (combined NEDC consumption). This corresponds to 139 grams of CO<SUB>2</SUB> per kilometre.

The new four-cylinder diesel engine also powers the E 220 CDI with 170 hp and the E 200 CDI with 136 hp which also have combined fuel consumption
figures of 53.3 mpg (available late summer 2009).

The top model in the new E-Class diesel range is the six-cylinder E 350 CDI with an output of 231 hp, which returns 40.9 mpg on the combined cycle,

a 2 mpg improvement over the previous E 320 CDI.
