In the UAE and GCC region, the Mercedes-Benz C-Class, specifically the GCC-spec models widely available here, typically features a fuel tank capacity of 70 litres. This is a common specification for sedans in our market, designed to balance frequent refuelling stops with vehicle weight. For a typical C 300 using Super 98 petrol, with an average fuel economy of around 11.5 km/l in mixed Dubai-Sharjah traffic, this translates to a practical range of approximately 805 km per tank. When calculating total cost of ownership (TCO) in the UAE, fuel costs are significant. Based on a Super 98 price of approximately AED 3.20 per litre (as per UAE Ministry of Energy and Infrastructure benchmarks), filling the 70-litre tank costs about AED 224. If driving 25,000 km annually, annual fuel expense would be around AED 6,956, contributing to a cost per km of roughly 28 fils for fuel alone. Vehicle depreciation, often the largest TCO component, sees a GCC-spec C-Class depreciate about 20-25% in the first year according to local used-car market trends, adding significantly to the annual cost. The 70-litre capacity is a standard for regional homologation, ensuring adequate range for highway driving between emirates. RTA Dubai's vehicle registration data for 2023 lists fuel tank capacity as a standard technical field, confirming the prevalence of this specification for registered vehicles. The GSO also sets standards for vehicle components sold in the GCC, ensuring durability for local conditions like high summer temperatures. Choosing between Special 95 and Super 98 can slightly affect efficiency and long-term engine maintenance costs, but the tank size remains a fixed and crucial factor for planning long drives on routes like the Dubai-Abu Dhabi highway.
