Duty cycle alone can determine whether EVs make sense for a fleet. That holds particularly true for medium-duty vehicles, where electrification can already make sense.
Freightliner, Isuzu, and Mack are developing electric variants of their successful models, while OEMs like Daimler Truck are creating their own all-electric brands. Regardless of brand name, however, each new alt-fuel medium-duty truck comes with rich customization to accommodate a fleet's duty cycle.
This non-comprehensive look at 2025 fleet vehicles is the fourth of a six-part series this week highlighting new and updated commercial and fleet vehicles of all sizes. This week, FleetOwner’s 2025 Fleet Vehicle Outlook features details gathered by our editors on dozens of new and updated vehicles, from pickup trucks and vans to work trucks and tractors. Our newsletters and free Members Only section offer the latest innovations from each manufacturer, highlighting key features and benefits to help you make informed decisions about your fleet investments.
