The basic General Dynamics prototype XM-966 HMMWV has a lightweight aluminum body on a proven chassis with full-time four-wheel drive, independent front wheel suspension, and a solid rear axle. The drive train combines a North American Deutz 160-hp air-cooled diesel engine with an automatic transmission and two-speed transfer case. Survivability features include a roll cage, run-flat tires, and an explosion-proof fuel tank kit. Crew accommodations include three seats across the front plus a fourth side-mounted jump seat in the cargo area. Each crew position is operable by the complete range of military personnel from the 5th percentile female to the 95th percentile male in arctic gear. All versions provide mounts and ample dedicated spaces for a wide range of GFE communications equipment.
The weapons carrier provides mounting for an unmodified GFE TOW system, and the armament kit includes a universal mount for the M60 (7.62mm) machine gun, the M2 (.50 cal) machine gun and the MK19 (40mm) grenade launcher. Mortar kits include provisions for transporting the 60mm, 81 mm, or the 4.2 inch mortars with standard ammunition loads.

Responding to HMMWV mission requirements, the North American Deutz 610 AirDiesel will operate at full load, full throttle, all day, anywhere. From hot desert sands to freezing mountain terrain, AirDiesel power performs in all environments without compromise. Direct fuel injection and an advanced combustion system deliver required power for quick acceleration and superior fuel economy for extended vehicle operating range. Deutz AirDiesels typically get about 20% better fuel economy than liquid-cooled diesels, with none of the liquid-cooling componentry that accounts for 40% of all engine maintenance and downtime.
Designed and built in North America, the Deutz 610 AirDiesel is North American-sourced with over 50% U.S. vendor support. AirDiesel meets NATO cold start requirements, down to — 26’F, with no costly and trouble-some add-on systems.

The proven conventional commercial 4WD HMMWV drivetrain provides a versatile combination of gear ratios for all terrain and highway uses.
The Heavy Duty Chrysler A727 automatic TRANSMISSION provides 3 forward speeds with gear ratios of 1.00, 1.45 and 2.45. The rugged truck NP218 TRANSFER CASE supplies full-time 4-wheel drive with 2 ratios of 1.0 and 2.61. The Dyneer True-Trac front biasing DIFFERENTIAL, and the No-Spin rear axle locking unit have proven to be very effective tractive differentials with superior durability and minimum maintenance, which enhance off-road mobility while providing predictable handling.
The WHEELS feature run-flat devices, and allow a “get-home” capability with all 4 tires flat with minimal maintenance and easy installation.
