INTERNATIONAL ProStar+ Benefits

The International® ProStar® owes much of its success to air. In fact, aerodynamic innovations have put this class 8 truck in a class by itself. A patented, new roof design optimizes slope. Minimized bumper-gap and a lowered hood have created an even more streamlined effect. What these innovations add up to is a 7%* fuel efficiency advantage over any class 8 on the road, conserving 1,400 gallons per truck annually. ProStar delivers where it counts, and that means outstanding fuel efficiency. Combine that with phenomenal service features and several power options, and you’ve got the most innovative and advanced heavy duty truck on the road.

Liquid or Dry Bulk

The International® ProStar® is one truck that doesn’t know the meaning of the word "downtime." The ProStar tractor’s aerodynamic design and lightweight options mean that even as the size of your load goes up, your level of safety and performance will never go down. With factory-installed roll-stability and traction control, you’ve got a truck ready for any driving condition.

When you’ve got this much riding on your frame, you should be confident that your truck is performing at its best. That’s why International is committed to keeping you riding strong from pick-up to drop-off.

Regional Haul

Short hauls mean tight deadlines, so you can’t afford unexpected downtime. The ultra stealthy International® ProStar® offers up to 7%* more fuel efficiency, which means less time at the pump and more time on the road. And with a wide-track front axle for a tighter turning radius and better maneuverability, you’ll find yourself more productive, and having an easier time staying that way. And with 6,000,000 miles of road testing under its wheels, rest assured the road won’t test you with anything your truck can’t handle.

Not all truckers make a home of the open road, and when short hauls are the bulk of your business, you need a truck that can make time a priority. That’s why International is committed to keeping you on schedule and your bottom line healthy.

MAXXFORCE 15 / 435-550 HP 1,550-1,850 lb. Torque

Built from a proven block and crank shaft with billions of miles of real-world experience. Available with up to 550 hp and 1,850 lb.-ft. of torque, MaxxForce 15 is the most powerful engine built by International®. Peak torque is achieved at 1,000 rpm and holds steady to 1,200 rpm. This reduces gear-shifting needs uphill and allows for shifting at lower speeds when accelerating. Fewer electrical connections increase system reliability. Premium cam and rolling element valve train system reduces friction and operational load to maintain peak efficiency across the power band. Interstage cooling between the turbos increases air density to maintain peak power as speeds increase. Premium foam-molded wire harness secures wiring and connections for increased reliability and durability. MaxxForce Advanced EGR reduces NOx in-cylinder without the use of liquid urea or additional maintenance.
