Introduced in 2017, the Polaris MRZR D2 brought a turbo-diesel engine and compact two-seat configuration to Polaris Government & Defense’s family of ultralight tactical vehicles. Designed for special operations and expeditionary forces, the MRZR D2 combines off-road mobility with the ability to travel inside several military transport aircraft.
The diesel-powered D2 joined the four-seat MRZR D4, giving military customers a smaller alternative when maneuverability, transportability and mission-specific equipment were more important than maximum seating capacity.
Why Polaris Developed the MRZR D2
Polaris introduced the original gasoline-powered MRZR 2 and MRZR 4 in 2013. Those vehicles established the MRZR platform as a compact tactical mobility system capable of transporting personnel, supplies and specialized equipment across difficult terrain.
The four-seat MRZR D4 followed in 2016 with a diesel engine capable of operating on diesel or JP-8 fuel. Polaris expanded the diesel line again in February 2017 with the two-seat MRZR D2.
At its introduction, Polaris said the diesel platform delivered approximately 80 percent more range than the comparable gasoline-powered MRZR while also providing greater electrical capacity for communications equipment and other mission accessories.
Polaris MRZR D2 Engine and Specifications
The MRZR D2 uses a four-stroke, three-cylinder turbo-diesel engine connected to a Polaris automatic PVT transmission. Current Polaris Government & Defense specifications list the engine at 55 horsepower and 69 lb-ft of torque.
- Engine: Three-cylinder, four-stroke turbo diesel
- Output: 55 horsepower
- Torque: 69 lb-ft
- Transmission: Automatic Polaris PVT
- Fuel compatibility: Diesel and military D1/D2 fuels, with the platform developed for military fuel requirements including JP-8
- Ground clearance: 12.5 inches
- Curb weight: Approximately 1,887 pounds
- Payload capacity: 1,000 pounds
- Seating: Configurable for two to four occupants
An integrated alternator supports the vehicle’s operating systems while providing additional auxiliary electrical power. That capability is especially important for radios, command-and-control equipment, surveillance systems and other mission hardware.
Designed for Internal Aircraft Transport
One of the MRZR D2’s defining characteristics is its ability to fit inside military transport aircraft. Polaris designed the vehicle for internal transport in aircraft including the:
- MV-22 Osprey
- CH-47 Chinook
- CH-53 Stallion
- C-130 Hercules
Internal transport allows an aircraft to deliver the vehicle with personnel instead of carrying it as an external sling load. Once unloaded, the MRZR can quickly extend the operating range of troops or transport equipment away from the landing area.
The relatively low weight, compact dimensions and folding or removable components also make the MRZR easier to deploy than a conventional full-size tactical truck.
Modular Cargo and Mission Configurations
The MRZR D2 retained the modular rear cargo area used by other vehicles in the MRZR family. Its Quick Rail cargo system can be configured for equipment, supplies, communications hardware or casualty evacuation.
Depending on its configuration, the D2 can accommodate up to four occupants or one litter. Tool-free access to the engine compartment helps simplify inspection and maintenance in the field.
Potential mission roles include:
- Rapid personnel deployment
- Reconnaissance and patrol support
- Command-and-control operations
- Casualty evacuation
- Transporting supplies and specialized equipment
MRZR D2 Compared With the Original MRZR Family
When the D2 arrived in 2017, the MRZR family included two- and four-seat vehicles with a choice of gasoline or diesel power:
- MRZR 2: Gasoline engine, two- to four-person configuration and 1,000-pound payload
- MRZR 4: Gasoline engine, four- to six-person configuration and 1,500-pound payload
- MRZR D2: Turbo-diesel engine, two- to four-person configuration and 1,000-pound payload
- MRZR D4: Turbo-diesel engine, four- to six-person configuration and 1,500-pound payload
The D2 occupied the compact diesel position in that lineup. It offered the footprint and payload capacity of the MRZR 2 while providing the diesel fuel compatibility, range and auxiliary-power advantages introduced with the D4.
The MRZR D2 Today
The MRZR D2 remains listed by Polaris Government & Defense alongside the four-seat MRZR D4 and the newer, larger MRZR Alpha platform. Although newer designs offer more power and payload capacity, the D2 continues to fill a distinct role where compact dimensions, diesel operation and aircraft compatibility are priorities.
The MRZR family also demonstrates how side-by-side vehicle engineering can be adapted for specialized military use. Polaris applied familiar off-road technologies—including an automatic PVT transmission, independent suspension and a compact vehicle layout—to a platform designed around deployment, payload and mission equipment.
