Mercedes A-Class hatchback (2013-2018) - MPG, running costs & CO2
The Mercedes A-Class diesel range returns impressive fuel economy
Taking the Mercedes A-Class’ economy figures at face value, most engines are pretty cheap to run. Compared to the BMW 1 Series or Audi A3, though, they’re about on level pegging. An unlimited-mileage warranty and decent servicing offers sweeten the A-Class’ deal.
Mercedes A-Class MPG & CO2
The cheapest Mercedes A-Class to run is the A180d diesel, which has claimed fuel economy of 80.7mpg and 89g/km CO2 emissions (with 16-inch wheels) placing manual SE examples in an impressively low 20% Benefit-in-Kind (BiK) company-car tax bracket. Some rivals are even more economical, though – the BMW 1 Series 1.6-litre diesel EfficientDynamics Plus can manage 83.1mpg.
Choosing the A200d diesel increases performance, yet this model still manages an average of 70.6mpg and CO2 emissions of 99g/km if you choose a Sport with an automatic gearbox. Even the fast A220d diesel can return an average of 68.9mpg. The popular A220d AMG Line model in 4MATIC four-wheel-drive guise returns 58.9mpg and emits 124g/km of CO2, occupying the 26% BiK tax bracket.
The most economical petrol models are the A160 and A180 automatic, which both manage 52.3mpg. Running costs and performance steadily increase until you get to the very fast A45 AMG model, which can only manage 40.9mpg.
Road tax will cost £140 a year, unless you add enough optional extras to take the price beyond £40,000, at which point the annual charge increases to £450 for years two to six of ownership (after an initial CO2-weighted year-one payment that’s usually included in the on-the-road price).
The A180d isn’t just the cheapest A-Class model to run, it’s also the cheapest to insure, sitting in groups 13 to 15. Unsurprisingly, the seriously rapid A45 AMG model costs the most to cover, occupying insurance group 41.
All Mercedes cars come with a three-year/unlimited-mileage warranty, which might not sound as good as Kia’s seven-year/100,000-mile cover, but could well appeal if you plan to cover a high annual mileage.
Mercedes offers fixed-price service plans across its range, which will help you to spread the cost of servicing over two, three or four years. Servicing is required yearly or at 15,000 mile intervals.
