Driver productivity is improved with a stair-step entry/exit system for International’s DuraStar and WorkStar trucks. Add in the ability to spec both vehicles with stand-up, right-hand drive (SRD) configurations and improved cab ergonomics, and productivity is increased while fatigue decreases.
The DuraStar includes a sloped hood, making SRD conversions work especially well, Navistar said, with plenty of forward and side-to-side visibility.
The WorkStar offers a cooling system mounted above the frame rail. The system protects the radiator in off-highway environments, but also allows for front-end power take-off (FEPTO) mounting without the need to put a hole in the radiator. The DuraStar’s colling package is developed from International’s PayStar 5900 SBA. It is mounted at the front of the frame rails for applications where a FEPTO is not required.
Both vehicles include standard wide-track front axles for greater wheel cut and a shorter turning radius.
The complete line of 2010 MaxxForce engines available include the mid-range diesels MaxxForce DT, MaxxForce 9 and MaxxForce 10, and the heavy-duty big bore options of the MaxxForce 11 and MaxxForce 13. The mid-range engines are available with up to 350 hp with horsepower rating improving to 475 with the heavy-duty engines.
All the engines meet 2010 EPA emissions requirements with the MaxxForce Advanced EGR emissions technology, an in-cylinder solution.
