Used Mercedes-Benz A-Class (2013 - 2018) Costs

Shunning the previous two generations’ MPV-like, high-roofed looks, the third iteration of the Mercedes-Benz A-Class is sleeker and longer, with styling that could turn the heads of traditional Volkswagen Golf buyers. Rivalling the likes of the Audi A3 Sportback, BMW 1 Series and Volvo V40 in the upper echelons of the mid-sized family hatch market, the A-Class itself is also the basis for several other cars.

Running costs

  • A 180 d claims an 80.7mpg average
  • Best petrols are rated at 54.3mpg
  • AMG A 45 officially manages 40.9mpg

Although it’s expensive to buy it needn’t cost lots to run a Mercedes-Benz A-Class, providing you do your homework and choose an efficient one.

The least-costly to run is the A 180 d in SE specification, with a claimed average consumption of 80.7mpg and CO2 emissions of just 89g/km.

If you don’t cover the annual mileage to warrant a diesel, then the picture’s not quite as rosy with petrol-sipping A-Classes. Opt for either the A 160 or A 180, again in SE trim but this time with the seven-speed twin-clutch automatic, and average unleaded consumption’s rated at 54.3mpg, with emissions of 121g/km of CO2.

Perhaps the most surprising is the range-topping Mercedes-AMG A 45’s official claim of 40.9mpg when riding on the standard 18-inch alloy wheels, although a real world figure of 30mpg is more likely if you drive it hard. Officially CO2 is rated at 162g/km. Specify the optional 19-inch rims and those figures worsen to 38.7mpg and 171g/km.

The estimated fuel cost figure is a guide to how much this model will cost to fuel each year, so you can compare between cars. It's calculated by using the model's average mpg (calculated from both town centre and motorway driving) and the average fuel price. It's based on the following cost-per-litre: petrol 127p and diesel 129p. Prices are updated daily.

Emissions summary

  • Cleanest diesel emits just 89g/km of CO2
  • Lowest petrol output is 121g/km
  • AMG A 45 as high as 171g/km on 19s

All of the diesel versions of the Mercedes-Benz A-Class have emissions below 120g/km of CO2, while all the petrol-powered models are higher than that figure.

Best of the lot is the SE specification A 180 d with the manual gearbox, with a CO2 output of just 89g/km, while the best-performing petrols – the A 160 SE and A 180 SE with automatic transmissions – are rated at 121g/km.

The one to avoid if low CO2 is top of your priority list is the Mercedes-AMG A 45 with the optional 19-inch wheel upgrade: expect to pay more in VED car tax courtesy of its 171g/km of CO2.
