For long-distance adventures or heavy-duty tasks, fuel range is one of the most important features. In this article, we will discuss the top five cars with the largest fuel tank capacities. It’s the tank size that affects how often you stop at the fuel pump and how far you can go between fill-ups (be it a diesel truck or a gas-powered vehicle). Models with the largest tanks are often built for power and towing capacity, but they also come with unique customization options for the super-duty driver. Keep reading this article if a 20 gallon tank that limits your route is not for you.
Why Fuel Tank Capacity Size Matters
- Long-distance travel, towing, und off-roading: A larger fuel tank directly impacts how far a vehicle can travel without needing to stop, especially during a road trip or while navigating remote terrain. When towing heavy loads or transporting cargo, high fuel consumption is unavoidable. A tank that holds 100 litres gives you more flexibility and fewer interruptions compared to a smaller 45 litres one, which can drastically reduce range.
- Range and refueling: For vehicles with high towing capacity (especially trucks and utility models), a larger tank is necessary. Commercial vehicles often face long routes with limited gas stations, where every extra liter counts. The amount of fuel your car can carry is directly linked to how long you can stay on the road.
- Differences between passenger cars and commercial vehicles: Passenger cars are designed for everyday use, with a focus on fuel efficiency, comfort, and short-distance driving. They typically feature fuel tank sizes ranging from 45 to 65 litres. Commercial cars are designed for heavy-duty purposes, such as towing, carrying loads, or transporting goods, and typically feature larger fuel tanks that exceed 100 litres.
