Power, refinement and economy are the three defining traits of the 4-cylinder in-line CDI diesel engines in the E 200 CDI and E 220 CDI models. Rarely has economical driving been so enjoyable, largely thanks to the impressive output and torque: 100 kW (136 hp)/340 Nm and 125 kW (170 hp)/400 Nm respectively. Plus both engines feature a Lanchester balancer and sophisticated insulation technology, thus ensuring superb refinement, as well as a standard-fit particulate filter to minimise soot emissions.


(E 200 CDI: fuel consumption combined: 7.1–7.5 l/100 km, CO2 emissions combined: 187–199 g/km; E 220 CDI: fuel consumption combined: 7.1–7.7 l/100 km, CO2 emissions combined: 188–202 g/km)[1]

The E-Class line-up also features common-rail diesel technology paired with the enhanced comfort of six cylinders. The V6 powerplants in the E 280 CDI and E 320 CDI produce 140 kW (190 hp) and 165 kW (224 hp) respectively and offer torque characteristics that are outstanding in the engines' respective displacement categories. Furthermore, the consistently lightweight design ensures low fuel consumption. And both models comply with the EU4 emission standard, while the standard-fit particulate filter further reduces soot emissions by a substantial margin.

The E 280 CDI and the E 320 CDI are also available with the 4MATIC all-wheel drive system.


(E 280 CDI: fuel consumption combined: 7.2–8.1 l/100 km, CO2 emissions combined: 191–215 g/km; E 320 CDI: fuel consumption combined: 7.6–8.1 l/100 km, CO2 emissions combined: 202–215 g/km)[1]
