A-Class: yearly fuel cost
The 2024 Mercedes-Benz A-Class brings premium polish to the hatchback class, and its fuel bill sits in sensible territory: 8,000 miles a year at £1.45 per litre costs roughly £1,101 — about £92 a month, or £21.20 a week. Its WLTP combined figure of 47.9 mpg is well below the hatchback segment average of 53.9 mpg across our 20-car sample, which is the trade-off for the three-pointed star — the A-Class is thirstier than the typical family hatch despite a modest 136 PS and 9.2-second 0–62 time. Five years of fuel adds up to around £5,500. You are paying partly for the badge, but in return you get a cabin and refinement that mainstream rivals cannot match. For many buyers, that trade-off is easily worth it.
In real-world use, A-Class owners generally report 44–46 mpg against the 47.9 mpg WLTP claim — the shortfall coming mostly from urban driving, where the mild-hybrid system helps but cannot work miracles. The most effective savings come from smooth, early upshifts, avoiding short trips where possible, and keeping motorway speeds at 65–70 mph. The A-Class also benefits from its aerodynamic shape, so removing roof boxes when not in use makes a measurable difference. Verdict: the fuel bill is the premium you pay for the badge; calm, anticipatory driving keeps it respectable and close to the official number. Using the A-Class's Eco driving programme for commuting, keeping windows closed at motorway speed to preserve its slippery aerodynamics, and servicing on schedule all help protect the official figure.
