Chassis
The Oshkosh JLTV A1 is powered by a 6.6-liter, inline 8-cylinder turbocharged diesel engine delivering 340 hp and over 900 Nm of torque, providing a favorable power-to-weight ratio for a vehicle in its class. The drivetrain is integrated with a fully automatic transmission system featuring six forward gears, one reverse gear, and a two-speed transfer case, ensuring constant four-wheel drive (4WD) capability for optimized off-road performance.
The suspension architecture comprises front and rear independent axles with coil springs, telescopic shock absorbers and torsion bar, enhancing vehicle stability and ride quality across uneven and rugged terrains. The platform rides on 385 /80 R20 tubeless run-flat tires, supported by a Central Tire Inflation System (CTIS), allowing real-time tire pressure modulation to adapt to varying surface conditions.
Braking performance is ensured through a dual-circuit air-over-hydraulic system with ventilated disc brakes on all wheels, supplemented by an Anti-lock Braking System (ABS) to maintain directional control and minimize stopping distances under adverse or emergency braking scenarios.
