2017 Mercedes E 220d Acceleration Test Shows New 2.0-Liter Is Great

However, most European buyers will not get a big twin-turbo V6 engine or even a regular diesel six-cylinder. For them, Mercedes has prepared the first all-new 4-cylinder diesel engine since... forever. It displaces just two liters (capacity is 1,950cc), thus reducing taxation in countries where cubic capacity matters.

Output has also been increased to 194 PS and 400 Nm of torque in the case of the E 220 d, which is 24 PS more than the outgoing E 220 CDI. Torque is the same and arrives 200rpm later, so the reduced displacement had some drawbacks.

However, performance is pretty great. This independent test of the E 220 d shows it reaches 100 km/h in 7.3 seconds, which is exactly what Mercedes says it will do.

While that might not sound too impressive for you power junkies, it's over one second better than the previous generation 220 model. Delivery is creamy and doesn't stop at the top end, like it did with the old 2.1-liter engine.

"First impression are that especially the low noise level of this diesel makes it a proper engine for such a luxurious car, even from the outside it is never annoying. On the other hand, the power delivery is really smooth, especially in the higher rpms it behave more like a petrol engine," says Automann, the guy who filmed this clip.

Unfortunately, we can't see how the model pulls at higher speeds, since the highway speed limit in Portugal is very low. However, considering how well Mercedes' new 9-speed automatic works and the fact that the aerodynamic new E-Class also lost weight, it should be decent.
