Which Cars Have Dual Fuel Tanks?

Cars equipped with auxiliary fuel tanks are mostly large off-road vehicles, such as the Nissan Patrol, Toyota Prado, Toyota Land Cruiser, and Toyota Land Cruiser Prado. These off-road vehicles have exceptional off-road capabilities and extended range, and only overseas versions come with dual fuel tanks. Below are specific details about the Patrol and Prado: 1. Nissan Patrol: The 2018 Patrol was launched in June 2017, complying with the China V emission standard. The 2018 Nissan Patrol 4.0L model measures 5165mm in length, 1955mm in width, and 1955mm in height, with a wheelbase of 3075mm. The 2018 Patrol is equipped with a 4.0L engine paired with a 7-speed automatic transmission. The 4.0L engine delivers a maximum output power of 205 kW, a maximum torque of 394 Nm, a top speed of 210 km/h, and a 0-100 km/h acceleration time of 11.9 seconds. 2. Toyota Prado 4.0L Middle East Version: The 2019 Prado 4.0L Middle East version features a waterfall-style front grille design, giving it a more rugged and bold appearance. The headlights are full and sharp, with high aggressiveness and recognition. The 2019 Prado 4.0L Middle East version is powered by a 4.0L engine paired with a 7-speed automatic transmission, delivering a maximum output power of 275 horsepower and a maximum torque of 381 Nm.

I've driven many long-distance trips myself and found the dual-tank design particularly practical when crossing deserts. Vehicles with long-range capabilities, like the Toyota Tundra, come standard with a 138-liter main tank plus an auxiliary tank, allowing you to travel a thousand kilometers in the desert without refueling. The Ford F-150 pickup's optional dual-tank version offers a combined capacity of over 140 liters, making it worry-free in areas with few gas stations. Many Middle East versions of the Nissan Patrol feature dual tanks, with symmetrically placed fuel caps and a total capacity of around 140 liters, ideal for traversing uninhabited regions. Older models like the Land Cruiser LC76 often come with auxiliary tanks as standard for off-road enthusiasts, making trips to Tibet and Xinjiang hassle-free. These vehicles have large fuel tanks and strong endurance, but their high fuel consumption makes them less economical for city driving.

In our off-road community, dual fuel tank vehicles are the most beloved. Take the Toyota LC200 Land Cruiser Middle East version for example, it comes with a factory-installed dual fuel tank totaling 138 liters, providing great peace of mind during expeditions. Although the Jeep Wrangler doesn't have a dual fuel tank as standard, aftermarket shops can install an auxiliary tank, which is essential for tackling places like Lop Nur. The top-tier Mitsubishi Pajero V97 comes with an auxiliary tank, offering over 90 liters combined capacity, making it perfect for routes like the Bingzhongluo-Chayu trail. Actually, many rugged off-road vehicles like the Nissan Terra and Haval H9 don't come with dual fuel tanks as standard, but owners often install them themselves. After all, when venturing into uninhabited areas, fuel is life. Installing an auxiliary tank costs around four to five thousand yuan, but it solves a major problem. Plus, when playing in sand or mud, you don't have to worry about fuel cutoff due to body roll.

Dual fuel tank vehicles are primarily designed for long-distance travel. For example, high-end versions of the Ford F-Series pickup trucks offer optional dual fuel tanks, with a total capacity often exceeding 140 liters. The Toyota Sequoia full-size SUV also has a dual fuel tank variant, providing exceptional range with the combined capacity. Certain models of the Chevrolet Silverado pickup support an optional auxiliary fuel tank, making it particularly practical for long-haul transportation. The GMC Sierra pickup features a similar configuration to the Silverado. In the commercial sector, medium-duty trucks commonly utilize dual fuel tank designs. These vehicles typically position the fuel tanks on both sides of the chassis, requiring special attention to fuel line inspections during maintenance.

Dual fuel tanks are quite common in the modification scene. The Ford Expedition, for example, can be fitted with an auxiliary fuel tank, which is available as a factory option. Aftermarket installations typically add around 40 liters. Some AMG versions of the Mercedes-Benz G-Class come with dual fuel tanks from the factory, with fuel caps on both sides. However, many vehicles don’t have this feature originally, such as certain models of the Tundra, where owners often spend thousands to install an aftermarket steel auxiliary tank. When modifying, it’s crucial to consider weight distribution to avoid vehicle drift. Professional off-road racing teams particularly favor vehicles with dual fuel tanks—for instance, Dakar Rally cars are usually modified to hold over 200 liters. When range is the top priority, having extra fuel tanks is never a bad thing.

Dual-tank vehicles are mainly divided into three categories: The first is American full-size pickup trucks, such as the Dodge Ram 1500, which can be optionally equipped with a dual-tank system; the second is large SUVs like the Lincoln Navigator, which comes standard with symmetrically positioned left and right fuel tanks; the third is professional off-road vehicles, such as the Land Rover Defender, which can extend its range by 40% when equipped with an auxiliary fuel tank. Commercial transport vehicles like the Isuzu D-MAX also frequently feature auxiliary tank designs. These vehicles refuel simultaneously from both sides during filling, resulting in longer refueling times but offering up to twice the range of ordinary vehicles. They are most practical for remote area travel, while urban driving may instead increase fuel consumption burdens.
