Which car is better for fuel economy, the Mercedes-Benz C220 or BMW 320d?

I've used the last versions of both those models for this comparison, which means a 2019 BMW 320d and a 2021 Mercedes-Benz 220d (I'm also assuming you're comparing diesels with diesels).

As such, the BMW holds a slim on-paper advantage with an official combined fuel consumption number of 4.4 litres per 100km, compared with 4.7 litres for the Benz. In the real world, that difference is a very, very small one and means the two vehicles are more or less line-ball for fuel economy.

Real world fuel consumption has a lot more to do with your driving environment and style than it does these laboratory-produced numbers. But the official numbers are valid on the basis that both vehicles were subjected to the same strict test regime, so they do provide a direct comparison, even if you'll almost certainly never match them in real life. Both, however, will surprise you with how frugal they can be.
