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.

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.
