Although undeniably not cheap, Mercedes-Benz A 45 AMG running costs aren’t as bad as you’d think for a car of this sort of performance. Officially the firm states that the car should return 40.9mpg on the combined cycle, but we’d expect closer to 30mpg during real-world driving and far less if you’re enthusiastic with your right foot.

CO2 emissions are 161g/km, which means road tax is a factor you’ll have to think about when budgeting.

Mercedes-Benz A45 AMG emissions are 161g/km since there’s only one engine and gearbox available. Although fairly low for a performance car, it’s still average in terms of how much road tax you’ll pay as it sits in road tax band G.

We don’t envisage big problems with Mercedes-Benz A 45 AMG reliability. The firm enjoys a decent record of reliability over recent years and the A-Class is no exception.
