E-Class Technology

The E-Class has always set standards, economically and technologically. Consequently, it also leads the way when it comes to measures aimed at reducing fuel consumption and emissions. It also boasts an outstanding drag coefficient

 

4-cylinder in-line engines. The 4-cylinder diesel unit with a choice of three power outputs displays a high level of sophistication: it offers impressively rich torque and instantaneous response, even at low revs. What’s more, the diesel engines consume less fuel, have low emissions and are both quiet and powerful.

 

This is made possible by a wealth of new technologies.Fourth-generation common-rail diesel technology impresses by virtue of an injection pressure increased to 2000 bar, optimised combustion chambers and extremely precise piezo injectors. High torque is available in every engine speed range thanks to the high ignition pressure and the turbocharger, while the requisite refinement comes courtesy of two Lanchester balancer shafts. Optimised alternator management ensures consistent use of the engine’s coasting phases, thus allowing recuperation of kinetic energy. Meanwhile the radiator shutter reduces the aerodynamic drag when the engines require only moderate cooling. The new engine generation represents a vast improvement on the already impressive equivalent engines installed in the out going model: output is up to 20 % higher and torque has been increased by up to 25 %, while fuel consumption and, therefore, CO 2 emissions are up to 23 % lower. This engine generation meets the requirements of the EU5 emission standard.

 

The modified BlueTEC technology in the E 350 BlueTEC (initially available for the Saloon) developing 155 kW has extremely low emissions. BlueTEC stands for measures aimed at optimising fuel consumption and for the cleaning and aftertreatment of exhaust gases. All of which gives this compression-ignition model one of the world’s cleanest diesel drive systems. Further hallmarks of the E 350 BlueTEC include exemplary emission figures, which already meet the requirements of future emission standards (EU6), low fuel consumption, effortlessly superior performance and a high torque of 540 Nm.
