Heavy-Duty Trucks, Class 7 & 8, >26,000 GVW

Navistar’s new 12.7-liter S13 diesel, shown here in an HX tractor, is part of an integrated powertrain that includes a proprietary automated manual transmission. It will be the last diesel developed by the company, which looks toward a transition to electric power. But the engine is typical of modern diesels that will work reliably and economically well into the 2030s.

Clean diesel technology still outpaces electric

Frank Raczon

July 17, 2023

Morrow’s 2023-model VNL760, dubbed “Purple Haze,” usually pulls vans carrying new furniture and averages more than 10 mpg. But it might also work well hitched to a flatbed toting pipe or building materials or a hopper loaded with aggregates. The Volvo’s aerodynamic lines, also used on nonsleeper models, reduce air drag at highway speeds. The I-Torque powertrain includes a D13TC, a 14-speed I-Shift, 2.16 to 1 axle ratio, and a 6x2 axle layout with a liftable pusher axle in the tandem.

The 114SD Plus mixer truck scoots along a gravel trail at a test center outside Ypsilanti. Rough portions of two off-road courses gave the chassis a workout, but it never faltered. Not used here were the Detroit Assurance safety systems that can help prevent accidents on highways. Powertrain includes a 440-horsepower Cummins X12, an Allison automatic, and Meritor rear axles.

Inside the International eMV Electric Truck

Tom Berg

Features are similar to diesel version

Viper red Class 7 eMV poses with a Cummins diesel-powered MV, International’s popular Medium Vocational model, at the Navistar Proving Grounds in Indiana. Cabs, frames, and suspensions are shared between the two otherwise dissimilar vehicles, though eMV’s gauge cluster is digital (inset). The drive system is taken from Navistar’s proven IC electric school buses. The eMV’s range is 135 miles, depending on operations, and the goal for future models is 200 miles. A Class 6 version for non-CDL drivers is also offered.

Rock solid and carrying rocks. That’s the Western Star 47X you see here, though it was actually carrying gravel: about 30,000 pounds or 10 yards of it, a little light for a “quad...

Money-green paint and geometric-decor graphics look good on the handsome 47X as it pauses after running one of two off-road courses at proving grounds outside of Detroit. The tandem and two lift axles make it a “quad” used in several states. Lenses of the cool-burning LED headlamps have heating grids to melt snow and ice. New “Daimler cab” is steel-framed, aluminum skinned, and wide enough for a crew of three. In the dump bed were 15 tons of gravel, but the truck would scale well under its rated GVW of 86,040 pounds.
