Parkers overall rating: 4 out of 5 4.0

There’s only one version available, so Mercedes-Benz CLA 45 AMG running costs are fairly simple to explain. Fuel economy is a claimed 40.9mpg on the combined cycle, which isn’t too bad for a car with such prodigious performance. CO2 emissions are between 161g/km and 165g/km depending on the size of the wheels you’ve picked.

With only one model, Mercedes-Benz CLA 45 AMG emissions are between 161 and 165g/km of CO2 (depending on wheel-size). Although that’s high compared to many cars these days, for something producing 355bhp it’s actually very reasonable.

It’s likely that Mercedes-Benz CLA 45 AMG reliability will be good. The A-Class it’s based on has a pretty good record. The engine is an unknown quantity since it’s new for this car, but it will have been tested extremely thoroughly before being put to use.
