The Joint Light Tactical Vehicle (JLTV) can offer a range of 300 miles on a tank of JP-8 jet fuel
The Joint Light Tactical Vehicle (JLTV) is a light utility/combat multi-role vehicle developed by Oshkosh Defense under the US military's Army-led Joint Light Tactical Vehicle program. The Oshkosh JLTV has undergone extensive testing and evaluation to ensure it is mission-ready and can fill critical capability gaps for US and international militaries.
One of the key requirements of the JLTV program was to improve fuel efficiency, which is a significant concern due to the high cost of delivering fuel to combat environments. The Oshkosh JLTV is designed to deliver a range of 300 miles on a tank of JP-8 jet fuel. This impressive range is achieved through the use of a Duramax 6.6-liter turbodiesel V-8 engine paired with an Allison six-speed automatic transmission. The engine is a militarized version of the Chevrolet Silverado HD and GMC Sierra HD's L5P Duramax diesel, modified to run on jet fuel or other combustible liquids such as diesel, kerosene, or alcohol.
The Oshkosh JLTV's fuel efficiency exceeds the government's expectations, and the company has developed a ProPulse hybrid diesel-electric powertrain that improves fuel economy and allows for exportable power both while stationary and on the move. This powertrain can be set up to export between 30 and 70 kW of power based on mission requirements.
The JLTV's engine provides 400 hp (298 kW; 406 PS) and 850 lb-ft (1,152 N-m) of torque, with a top speed of 70 mph. The vehicle's throttle response is impressive, with no noticeable lag from the turbocharger. The combination of powerful performance and efficient fuel economy makes the JLTV a highly capable and versatile vehicle for modern battlefield environments.

The Oshkosh JLTV has a Duramax 6.6-liter turbodiesel V-8 engine
The Oshkosh JLTV, or Joint Light Tactical Vehicle, is a light utility/combat multi-role vehicle. It is designed to improve performance, payload, and protection capabilities. The Oshkosh JLTV has a Duramax 6.6-liter turbodiesel V-8 engine, which is based on the architecture of the General Motors Duramax L5P. The engine provides 400 hp and 850 lb-ft of torque. The Duramax L5P engine is known for its reliability and power density. In fact, during testing, an Oshkosh JLTV ingested water and still went another 2,000 miles before requiring engine repairs.
The Duramax 6.6-liter turbodiesel engine is paired with an Allison six-speed automatic transmission, which provides quick and smooth shifting. The Oshkosh JLTV is designed to offer a range of at least 300 miles on a tank of JP-8 jet fuel, and its fuel efficiency exceeds the government's expectations. The ProPulse powertrain, an option for the vehicle, can be set up to export between 30 and 70 kW of military-grade power.
The Oshkosh JLTV is a highly capable vehicle, able to go anywhere the lighter unarmored Humvee can, but with three times the speed and comfort. It has a top speed of 70 mph and can accelerate from 0 to 60 mph in around 10 seconds. The vehicle's throttle response is linear and instantaneous, thanks to its powerful engine and close gearing.
The Oshkosh JLTV has been extensively tested and evaluated to ensure it is mission-ready. It features a patented TAK-4i intelligent independent suspension system, which allows it to quickly adjust to diverse transportability needs. The vehicle can be transported by air, land, and sea, making it highly versatile and adaptable to various battlefield environments. Overall, the Oshkosh JLTV is a reliable and high-performance vehicle that exceeds expectations in terms of fuel efficiency and power.

The ProPulse powertrain can improve fuel economy by up to 35%
The Joint Light Tactical Vehicle (JLTV) is a light utility/combat multi-role vehicle. The Oshkosh-developed JLTV was selected for acquisition under the US military's Army-led Joint Light Tactical Vehicle program. The L-ATV was designed to deliver a level of protection comparable to that of heavier and less manoeuvrable Mine Resistant Ambush Protected (MRAP) class designs.
The L-ATV can be fitted with the Oshkosh ProPulse diesel-electric powertrain, which was previously fitted to the Oshkosh Heavy Expanded Mobility Tactical Truck (HEMTT) and MTVR. The ProPulse powertrain can improve fuel economy by up to 35% and serves as an on-board generator with enough output to power an entire airfield or hospital, generating up to 120 kW of AC power for external operations. The hybrid powertrain was not a requirement of the JLTV program.
The ProPulse powertrain is a major component of fuel efficiency. It can be set up to export between 30 and 70 kW of military-grade power based on mission requirements. The L-ATV is designed to be quick, offering at least 300 miles of range on a tank of JP-8 jet fuel, and to be as mobile as the original Humvee off-road.
The initial LCTV prototype used Oshkosh's ProPulse diesel series hybrid system, but the company instead decided to power the L-ATV JLTV by a tried-and-true powertrain that GM Heavy Duty truck owners swear by: a Duramax 6.6-liter turbodiesel V-8 paired with an Allison six-speed automatic transmission. Chosen because of its reliability and power density, the JLTV's engine is essentially a militarized version of the new 2017 Chevrolet Silverado HD and GMC Sierra HD's L5P Duramax diesel.

The fuel efficiency of the JLTV is 10 mpg
The Joint Light Tactical Vehicle (JLTV) is a light utility/combat multi-role vehicle. The Oshkosh-developed JLTV was selected for acquisition under the US military's Army-led Joint Light Tactical Vehicle program. The Oshkosh L-ATV, now redesignated as the JLTV, was chosen as the winner of the competition.
The JLTV is powered by a Duramax 6.6-liter turbodiesel V-8 engine paired with an Allison six-speed automatic transmission. The engine produces 400 hp and 850 lb-ft of torque. The vehicle has a top speed of 70 mph and can accelerate from 0 to 60 mph in around 10 seconds.
One of the key focuses of the JLTV program is fuel efficiency, especially due to the high cost of delivering fuel to combat environments. Lockheed Martin, one of the competitors for the JLTV contract, has designed their JLTV to achieve a fuel efficiency of 10 mpg. According to Hasse of Lockheed Martin, this fuel efficiency is impressive considering the vehicle's weight of around 22,000 pounds and its ability to operate in off-road and cross-country terrain.
Oshkosh, another competitor, has also developed a hybrid diesel-electric powertrain called ProPulse that improves fuel economy. The ProPulse powertrain can be configured to export between 30 and 70 kW of power based on mission requirements. While the exact fuel efficiency of the Oshkosh JLTV is not mentioned, it is stated to exceed the government's expectations.
