LOUISVILLE, Ky. — Navistar went through its ProStar Class 8 truck “with a fine tooth comb” and came up with enough improvements to warrant introducing a new generation of the top-selling truck, dubbed the International 2010 ProStar+.
The new generation includes improvements to the truck’s aerodynamics and a reduction in curb weight, as well as a number of improvements to the cab’s interior.
The truck is powered by the company’s Advanced EGR MaxxForce 11 and MaxxForce 13 engines, which don’t require liquid urea to meet the 2010 emissions regulations.
The aerodynamic enhancements include 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 lbs lighter than its predecessor. When you include the MaxxForce 13, with its compacted graphite iron (CGI) cylinder block, and MaxxForce Advanced EGR emissions technology, the ProStar+ has an additional 600-lb advantage versus the leading 15-litre engine, providing an extra 1,300 lbs of added payload capacity and fuel economy benefits, according to Jim Hebe, vice-president sales for North America.
The ProStar+ also 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% increase in captured storage and a 50% percent improvement in total storage.
In addition, the ProStar+ cab environment has become even quieter. ProStar+ cab noise levels have dropped 9% 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.
