    Gray truck on a gray day, but a bright driving experience: 2021 Model 567 dump is ready to roll at Ohio Peterbilt. It has very low miles, the right specs for northeastern Ohio, and looks and performs like new. That makes it a compelling argument for buying “used.”

    A trio of single-rear-axle plow trucks sporting green and amber strobes cleans a stretch of Ohio highway after a storm has passed. Green lights are used only on snowplows, differentiating them from other road-maintenance equipment with amber-only lights.

    More than half of all heavy trucks now in use are more than 10 years old, according to industry estimates, so their diesels lack pollution controls used in modern trucks. Operators keep the old, reliable vehicles because they can’t or won’t spend money on expensive new equipment.

    Side-by-side look shows how electric power performs against diesel.
    Tom Berg
    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.
