Efficiency boost for Mercedes-Benz E-Class
17th July, 2011
"E" for "Efficiency": this is the well-proven success formula with
which the E-Class saloon is again raising the bar, and showing how the intelligent interaction between technical
innovations throughout the powertrain can reduce fuel consumption even further.
For example, in the E 250 CDI BlueEFFICIENCY a combination of the new 7G-TRONIC PLUS automatic transmission and the
standard ECO start/stop function has led to a decrease in consumption by over 10 per cent compared to the outgoing
Comprehensively improved automatic transmission: 7G-TRONIC PLUS
This comprehensively improved 7-speed automatic transmission is standard equipment in the E-Class sedan range. One
major feature of the latest evolutionary phase of 7G-TRONIC is a new generation torque converter with a much more
dynamic response. Noise and vibration levels have also been reduced thanks to a new hydraulic circuit, improved
dampers and a new torque converter lock-up clutch with considerably reduced slip even under low loads.
With low-friction bearings and seals, as well as a new transmission fluid with lower viscosity, the transmission
itself also contributes to fuel economy. Thanks to the long service life and unchanged cooling efficiency of the
transmission fluid, this now only needs to be replaced every 125,000 kilometres. The transmission's improved
electro-hydraulic control unit and new, low-friction materials in various areas, as well as optimised software, lead
to improved smoothness.
The four-cylinder diesels in the E-Class: considerable increase in efficiency
Particularly in the four-cylinder diesel variants of the E-Class, the ECO start/stop function and 7G-TRONIC PLUS
make for a considerable increase in efficiency. The engine specialists have also optimised the oil pressure control
and belt drive, and equipped the turbocharger with a self-regulating compressor.
In the E 220 CDI BlueEFFICIENCY with 125 kW and E 250 CDI BlueEFFICIENCY with 150 kW with the standard 7G-TRONIC
PLUS, combined consumption and CO2 emissions have fallen by 16 per cent to 5.1 l/100 km and 135 g/km.

The comprehensive update to the powertrain has also brought significant fuel savings for the four-cylinder petrol
engine. The E 250 BlueEFFICIENCY, fuel consumption and CO2 emissions of 7.2 l/100 km and 166 g/km are five per cent
lower than the figures for the preceding model with a 5-speed automatic transmission.

Comfort and design: perfected in detail
In addition to the new powertrain features, the Mercedes-Benz E-Class now has new interior and exterior details.
These include the full-colour TFT display in the instrument cluster, which is also capable of showing
three-dimensional graphics. Another new feature is the standard DIRECT-SELECT selector lever for 7G-TRONIC PLUS on
the steering column - also in the four-cylinder models. The driver is able to select transmission positions "P", "N",
"R" and "D" by nudging a selector on the steering column. The operating commands are transmitted electronically, by
cable. The package includes steering wheel gearshift paddles. Another standard feature in the ELEGANCE line is the
luxury front head restraint, whose side bolsters can be adjusted as required.
