The Tiger I was a German heavy tank of World War II that began operational duty in 1942 in Africa and the Soviet Union. The Tiger I was expensive to produce and maintain, and its high fuel consumption made it impractical in the face of shrinking resources. The Tiger I was powered by a petrol (gasoline) engine, specifically a 12-cylinder Maybach HL210 P45 engine, which was later upgraded to the HL 230 P45. The Fahrschulpanzer VI variant of the Tiger I was designed to run on either compressed Towngas gas or wood gas due to fuel shortages. The Tiger II, which entered production in August 1944, also used a petrol engine, the Maybach HL 230 P30, which was underpowered and consumed a lot of fuel.

What You'll Learn
The Tiger I tank used petrol (gasoline)
The Tiger I was a German heavy tank that was operational during World War II from 1942 to 1944 in Africa and the Soviet Union. It was an advanced design for its time, featuring a powerful 8.8 cm KwK 36 gun and an armoured fighting vehicle. However, its production required significant resources, making it expensive. Only 1,347 Tiger I tanks were produced, and they were known for their high fuel consumption.
The fuel consumption of the Tiger I was approximately 2.75 gallons per mile, which was a significant factor in its operational range. With a total fuel capacity of around 125 gallons distributed across four fuel tanks, the Tiger I had limited mobility and required frequent refuelling stops, especially when travelling off-road. German logistic plans anticipated a maximum on-road range of 121.2 miles (195 km) and an off-road range of 68.4 miles (110 km) before refuelling was necessary.
To address fuel shortages, a variant of the Tiger I, known as the Fahrschulpanzer VI Tiger, was modified to run on alternative fuels. These tanks were used for training crews and were not deployed in combat. They could operate using compressed Towngas gas (Stadtgas System) or wood gas (Holzgas System).
The Tiger I's petrol engine and high fuel consumption contributed to its operational limitations. Despite its advanced design and powerful weaponry, the Tiger I's fuel requirements posed logistical challenges for the German military during World War II.

The Fahrschulpanzer VI variant could run on gas or wood gas
The Tiger I was a German heavy tank used in World War II. It was an expensive tank to produce and maintain, with a high fuel consumption rate of approximately 2.75 gallons per mile. The total fuel capacity of its four fuel tanks was around 125 gallons, which limited its operational range and required frequent refuelling. German logistic plans estimated that the Tiger I could travel approximately 121 miles on roads and 68 miles off-roads before needing to refuel.
The Fahrschulpanzer VI variant of the Tiger I tank was designed to address the issue of fuel shortages. These tanks were modified to run on either compressed Towngas gas (Stadtgas System) or wood gas (Holzgas System). They were used for training Tiger tank crews and were not intended for combat.
The Fahrschulpanzer VI, or "driving school Tiger tanks," had a mixture of turreted and turretless hulls. They played a crucial role in training tank crews without relying on the limited supply of conventional fuel.
The ability of the Fahrschulpanzer VI variant to utilise alternative fuels showcases the resourcefulness and adaptability of the German military in the face of fuel shortages. By modifying the engines to run on compressed gas or wood gas, they could continue to train their tank crews and maintain a level of operational readiness even with limited fuel supplies.
Overall, the Fahrschulpanzer VI variant of the Tiger I tank represented a creative solution to the challenges posed by fuel shortages, ensuring that crew training could continue and that the German military could maintain their proficiency in operating these formidable fighting vehicles.

The Tiger I had four fuel tanks with a total capacity of 125 gallons
The Tiger I was a German heavy tank that saw action in World War II. It was an expensive and powerful machine, with a combat weight of 56 tons. The tank was equipped with a 12-cylinder Maybach HL210 P45 petrol engine, which produced 650 horsepower and a top speed of 24 mph. However, this engine was found to be underpowered, and later models of the Tiger I featured an upgraded HL 230 P45 engine, generating 699 horsepower.
The four fuel tanks of the Tiger I were located in two separate rear compartments, with each compartment housing a fuel tank, radiator, and fans. This layout was typical of German tank designs. The rear compartments were designed to be flooded when the tank forded bodies of water, with an unusual ventilation and cooling system for when the tank was underwater. However, this ability was costly and provided limited practical value, so it was removed from production lines in August 1943.
The Fahrschulpanzer VI variant of the Tiger tank featured modified engines that could run on alternative fuels, such as compressed Towngas gas or wood gas. These modified tanks were used for training Tiger tank crews and were not deployed in combat. The standard Tiger I and its variants consumed significant amounts of fuel, which contributed to their operational challenges and limitations during World War II.

The Tiger I had a high fuel consumption rate of 2.75 gallons per mile
The Tiger I was a German heavy tank that saw action in World War II, beginning operational duty in 1942 in Africa and the Soviet Union. The Tiger I was an expensive tank to produce and maintain, with a high fuel consumption rate.
The Tiger I was powered by a petrol (gasoline) engine, specifically a Maybach HL210 P45 engine. This 12-cylinder engine had a displacement of 21.35 litres and produced 485 kW (650 hp) at 3,000 rpm, giving the tank a top speed of 38 km/h (24 mph). However, this engine was found to be underpowered for the vehicle, and so an upgraded HL 230 P45 engine was introduced from the 251st Tiger onwards.
The high fuel consumption rate of the Tiger I was a notable issue. The tank consumed approximately 2.75 gallons of fuel per mile, leading to a limited operational range. The total fuel capacity of the four fuel tanks was around 125 gallons (568 litres), meaning that the Tiger I could only travel around 121.2 miles (195 km) on road and 68.4 miles (110 km) off-road before needing to refuel. This high fuel consumption rate was a significant logistical challenge for German forces and contributed to the limited production and deployment of the Tiger I, with only 1,347 Tiger I tanks produced.
The high fuel consumption was due in part to the powerful engine and the weight of the tank, which was approximately 56 tons. This weight often exceeded the limits of small bridges, which typically had a 35-ton weight restriction. The Tiger I's weight and powerful engine gave it exceptional performance for its time, but also contributed to its high fuel consumption.
To address fuel shortages, a variant of the Tiger I, known as the Fahrschulpanzer VI Tiger, was modified to run on alternative fuels. These tanks could operate on either compressed Towngas gas (Stadtgas System) or wood gas (Holzgas System) and were used for training Tiger tank crews rather than in combat.

The Tiger II was under-powered and consumed a lot of fuel
The Tiger II was a German heavy tank that served as an upgrade to the Tiger I, which was in use from 1942 to 1944. The Tiger II was under-powered, a common issue with heavy tanks of World War II, and it consumed a lot of fuel. This was a problem as fuel was in short supply for the Germans. The Tiger II was powered by a 700 PS (690 hp, 515 kW) V-12 Maybach HL 230 P30 engine, the same engine used in the Panther and Tiger I tanks, which were much lighter vehicles.
The Tiger II's engine produced a maximum of 3000 rpms, but it could not be reliably operated at this level, and crew manuals recommended a maximum of 2600 rpms. The Tiger II had a combat weight of 56 tons, which was often too heavy for small bridges, and so it was designed to ford bodies of water up to 5 meters deep. This required 30 minutes of set-up time, with the turret and gun locked in the forward position, and a large snorkel tube raised at the rear. The two rear compartments, which each contained a fuel tank, radiator, and fans, could be flooded.
The high fuel consumption of the Tiger II was a significant issue. The Tiger I, which used the same engine, had a fuel consumption rate of approximately 2.75 gallons per mile, with a total fuel capacity of around 125 gallons. This limited the operational range of the tank, requiring frequent refuelling stops, especially when travelling off-road. German logistic plans estimated that the Tiger I could travel 121.2 miles on-road and 68.4 miles off-road before refuelling. The Tiger II, with its higher weight, likely had an even shorter operational range.
The under-powered engine of the Tiger II was a result of the tight engine compartment and other technical limitations, which made it impossible to install a larger, more powerful motor. Attempts were made to increase the power of the engine, such as with the Maybach HL234, which would have increased power to at least 800 PS (hp). However, this engine was not ready for production before the end of the war. The high fuel consumption and under-powered engine of the Tiger II were significant drawbacks, limiting its operational effectiveness and contributing to the loss of many tanks due to mechanical breakdowns and lack of fuel.
