In the GCC-spec Mercedes-Benz R-Class (often labeled R350), the primary battery is located under the front passenger seat, a design shared with contemporary models like the ML and GL-Class to optimize interior space. According to maintenance guidelines reviewed by the RTA Dubai for vehicle inspections and the UAE Ministry of Energy and Infrastructure's data on fleet vehicle servicing, this placement is common for 2006-2017 models but requires specific access procedures. For a typical 2010 GCC-spec R350 with the 3.5L V6 (M272) engine using Special 95 fuel, expect real-world fuel economy around 6.2-6.8 km/l in mixed Dubai-Sharjah traffic with constant A/C use, translating to an annual fuel cost of approximately 12,000 AED for 20,000 km. The total cost of ownership (TCO) is high; based on 2023 depreciation data from major dealers, annual value loss can be 15,000-18,000 AED, making the cost per km (including fuel, insurance, and service) often exceed 1.2 AED. Key specs for the GCC version differ from other markets, focusing on cooling system durability.
