LOUISVILLE, Ky. (March 25, 2010) – Navistar, Inc. today took the Mid-America Trucking Show by storm once again, introducing the all-new International® ProStar®+ (Plus).

As the top-selling Class 8 on-highway truck in the combined U.S. and Canada market, the International ProStar® set the standard as the industry’s most aerodynamic and fuel-efficient tractor on the road. The 2010 ProStar+ raises the bar even higher.

“We weren’t satisfied with simply being the best—we were determined to make the best even better,” said Jim Hebe, Navistar senior vice president, North American sales operations. “Along with improving the truck’s aerodynamics and reducing its curb weight, we’ve made a number of driver-friendly interior improvements and integrated a no-hassle emissions solution that allows drivers to do what they do best.”

The Ultimate Driver’s Truck
Powered exclusively by the Advanced EGR MaxxForce® 11 and MaxxForce® 13, the ProStar+ is the only no-hassle 2010 emissions solution. With MaxxForce Advanced EGR, customers won’t have the worry or inconvenience of finding or filling liquid urea.
Emissions compliance isn’t the only feature of the ProStar+ designed with the driver in mind. Listening to direct feedback from drivers, the ProStar+ includes dramatically refined interior functionality. A re-engineered overhead console allows for easier reach and even includes an in-cab paper towel dispenser. Storage has been dramatically improved, with the Hi-Rise model seeing a 150 percent increase in captured storage and a 50 percent improvement in total storage.

In addition, the ProStar+ cab environment has become even quieter. Already boasting one of the quietest cabs in the segment, ProStar+ cab noise levels have dropped nine percent compared to last year’s ProStar. Other driver satisfaction improvements include a 20-pound force reduction in clutch feel for better driver comfort, providing easier shifting and less fatigue.

Lowest Cost of Ownership
Already the industry’s most aerodynamic and fuel-efficient Class 8 truck, the ProStar+ offers new aerodynamic enhancements, including optional full-length chassis skirts for sleepers as well as a new cab roof air fairing for day cab models. ProStar+ also includes many new powertrain features that improve fuel economy, including a clutched air compressor, variable speed fan, low viscosity engine oil and fuel-efficient rear axle lubricant.

As vehicle weight continues to be a top priority for customers, the ProStar+ is 700 pounds lighter than its predecessor. When you include the MaxxForce 13, with its durable, lightweight compacted graphite iron (CGI) cylinder block, and MaxxForce Advanced EGR emissions technology, the ProStar+ has an additional 600-pound advantage versus the leading 15-liter engine, providing an extra 1,300 pounds of added payload capacity and fuel economy benefits.

“With the ProStar+, we challenged ourselves to make the best even better,” Hebe added. “With the aerodynamic and weight-saving enhancements, the re-engineered and highly functional interior and the no-hassle emissions technology of our MaxxForce Advanced EGR engines, the new ProStar+ provides an unparalleled level of driver satisfaction, while delivering the lowest cost of ownership in the industry.”
