The safe continuous driving duration for a modern GCC-spec car in the UAE, especially in summer, is typically 8-10 hours with mandatory breaks for the vehicle and driver. This is not about the engine's limit, but the strain on cooling systems, tires, and fluids under extreme heat. According to RTA Dubai's vehicle safety guidelines and operational data from fleet operators, prolonged driving in temperatures consistently above 45°C necessitates a 30-45 minute cooldown stop every 4-5 hours to prevent overheating. The key factors are the car's condition and the driving environment.
For a well-maintained 2022 Toyota Land Cruiser with a V6 engine using Super 98, cruising on the Dubai-Abu Dhabi highway with the air conditioning on, the main limitation is often fuel capacity, allowing for 600-700 km before refueling. However, for an older sedan like a 2015 Nissan Sunny with a smaller radiator, battling stop-and-go Dubai-Sharjah rush-hour traffic, the risk of the coolant temperature rising is significantly higher within 2-3 hours. The total cost of ownership (TCO) for such intensive use rises sharply due to accelerated wear. Based on common fleet maintenance logs, annual depreciation can increase by 15-20% for a vehicle used for daily long-distance commutes compared to normal city use, and the cost per km (including fuel at approx. AED 0.25/km for a mid-size SUV, more frequent oil changes, and brake servicing) can be 30% higher. MOI UAE's traffic safety campaigns consistently advise checking coolant levels and tire pressure before any long trip, as these are the primary points of failure during extended summer drives. A modern car's cooling system is designed for UAE heat but requires periodic rest. Older vehicles need more frequent checks during continuous operation. The primary risk in summer is coolant and tire degradation, not just engine failure.
