The US Army is looking to reduce the tank's weight and fuel consumption
The M1 Abrams tank is a powerful piece of military hardware, with thick armour and a large fuel capacity. While its exact fuel capacity is not publicly available, several sources note that the Abrams tank is known for its low fuel efficiency. A 1990 report by the Project On Government Oversight criticised the tank for its high costs and low fuel efficiency compared to other tanks of similar power, such as the Leopard 2.
The US Army is always looking for ways to improve the performance and efficiency of its vehicles, and reducing the weight and fuel consumption of the Abrams tank is likely a key area of focus. Here are some potential strategies they could employ:
Reducing Weight
- Remove unnecessary cargo: The weight of a vehicle directly impacts its fuel consumption, with heavier vehicles using more fuel due to increased inertia and resistance. Removing any unnecessary items from the tank can help reduce its weight and improve fuel efficiency.
- Optimise armour materials: The Abrams tank's armour is thicker than that of previous tanks, which contributes to its weight. The US Army could explore advanced materials that offer the same level of protection but with reduced weight.
- Modular design: Implementing a modular design approach would allow the tank to be customised for specific missions, removing unnecessary weight for certain operations.
Improving Fuel Efficiency
- Engine and fuel system upgrades: Upgrading the engine and fuel system with more efficient technologies can help improve fuel economy.
- Driving behaviour: While not directly applicable to tank operations, driving behaviours such as maintaining a steady pace, avoiding hard acceleration and braking, and minimising idle time can significantly impact fuel consumption.
- Fuel choice: Selecting the appropriate type of fuel for the tank's engine can also help improve fuel efficiency.
By implementing a combination of weight reduction strategies and fuel efficiency improvements, the US Army can work towards reducing the fuel consumption of the Abrams tank, improving its operational efficiency and reducing logistical burdens associated with fuel supply.

The M1 has external fuel storage in turret racks
The M1 Abrams tank has been criticised for its high costs and low fuel efficiency. The M1's AGT-1500 gas turbine engine consumes fuel at a rate of 5.93 gallons per mile, and it has a 495-gallon fuel tank. This means that it takes 2000 gallons of fuel to fill up a platoon of four M1 Abrams tanks. The M1 has external fuel storage in turret racks, which has proven to be a vulnerability in combat. During the Iraq War, some tanks were put out of action when flammable fuel stored externally in turret racks was hit by small arms fire, causing engine fires.
The M1 Abrams tank's fuel and ammunition are stored in armoured compartments with blowout panels. These are designed to protect the crew from the tank's own ammunition exploding if the tank is damaged. The main gun's ammunition is stored in the rear section of the turret, with blast doors that open under power by sliding sideways only to remove a round for firing and then automatically close. Doctrine mandates that the ammunition door must be closed before arming the main gun.
The M1 Abrams is protected by advanced armour, which, along with its low silhouette and agility, increases its survivability on the battlefield. The tank has a halon firefighting system to automatically extinguish fires in the crew compartment. The engine compartment has a separate firefighting system that is engaged by pulling a T-handle located on the left side of the hull. The toxicity of Halon 1301 gas at 7% concentration is much lower than the combustion products produced by fire in the crew compartment, but the Halon gas can still be dangerous to the crew. Therefore, the crew compartment also contains small handheld fire extinguishers.
The M1 Abrams' external fuel storage in turret racks has been a vulnerability in combat, as enemy forces have targeted this weak point. This has resulted in engine fires and the loss of tanks. The tank's firefighting systems and the armoured compartments with blowout panels help to protect the crew and minimise the impact of fuel fires. However, the M1's fuel efficiency has been a point of criticism, with its high fuel consumption contributing to its high logistical footprint.
