MPG, running costs & CO2 Rating

2.5 out of 5

Rather like a Porsche 718 Cayman GT4 or Audi TT RS, the Mercedes-AMG A 45 S is a seriously hardcore performance car with a higher power output than many racing cars. With 415bhp, downforce generating wings and wide tyres, it would require a miracle to be genuinely fuel-efficient. During our testing we managed around 30mpg combined when driving carefully, which is fairly close to Mercedes’ official figure of 34mpg.

After the first year, the current road tax system also means its £145 annual payment will be no different to any other petrol or diesel. However, a forecourt price of more than £40,000 will mean the A 45 S is liable for a luxury car surcharge of £320 in the first five renewal years, taking the total to £465.

Insurance is likely to be particularly steep, with a rating of group 50 expected. The A 45 S will also sit in the top band for company-car tax and consumable parts such as tyres, brakes and even oil will be expensive.
