The Navistar MaxxForce 15 diesel is available with up to 550 horsepower and 1,850 lb.-ft. of torque. Peak torque is reached at 1,000 rpm and holds steady to 1,600 rpm, the company says. This reduced gear shifts in uphill terrain and allows for shifting at lower speeds when accelerating.
The MaxxForce 15 will be built in Navistar’s Huntsville, Ala., engine plant and is available in vocational configurations. Engine options for on-highway (non-vocational) applications will be available in late summer.
