Ford
Ford’s medium-duty lineup includes the F-650 and F-750, both of which are available with either a gas or diesel powertrain via the 7.3L V8 gasoline engine or 6.7L Power Stroke turbo diesel engine. The trucks have a GVWR range of 25,600 to 37,000 lb.
Both the F-650 and F-750 feature a 39.4-inch chassis height and standard 22.5-inch wheels. The V8 offers 335 hp and 468 lb.-ft. of torque. The Power Stroke offers a standard 270 hp and 700 lb.-ft. of torque with an available rating up to 330 hp and 750 lb.-ft. of torque. Both engines are paired with a Ford TorqShift transmission—the HD 10 speed with the diesel, and the HD 6 speed with the gas. A PTO is standard with HD 10 speed and available with the 6 speed.
The 2025 Ford Medium Duty trucks have an ergonomic steering wheel and instrument cluster, steering wheel audio controls, and available factory-installed auxiliary switches. The trucks are equipped with Ford Co-Pilot360 Technologies, with features such as Hill Start Assist and Driver-Assist Technology Package (which includes pre-collision assist with automatic emergency braking, auto high-beam headlights, lane-keeping alert, and more).
More than gas and diesel: Ford Medium Duty lineup offers alternative fuel options, including compressed natural gas and propane autogas.
Freightliner
Freightliner’s Plus series enhances its medium-duty and severe-duty vehicle lines. The M2 106 Plus, M2 112 Plus, 108SD Plus, and 114SD Plus can be spec’d between Class 6 and Class 8.
The enhanced models, which began serial production in late 2023, updated the interior and electrical systems of the medium-duty M2 and vocational SD models. All of the Plus series vehicles are available with Daimler Truck North America's safety and connectivity suites from Detroit Assurance for customers combining Detroit or Cummins engines with the Detroit D12 transmission.
The QuickFit Electrical System was engineered to simplify upfits. According to the OEM, it delivers easier access to critical connection points, more power sources, programmable switches, customizable parameters, and interlock features, making upfits more flexible.
Aggressive performance: The vocational vehicles include low-speed maneuverability technology from the Detroit DT12-V transmission. There is an off-road mode featuring aggressive shifting for sustained momentum and performance on rough terrain, a hill-start aid to guard against rolling back on steep grades, and a rock-free mode to reduce downtime caused by wheel-stuck situations.
Hino
The new Hino L Series trucks, available in Class 6 and Class 7 versions, feature an exterior redesign that includes a bolder front fascia and optional LED headlights.
The trucks are standard with the Cummins B6.7L diesel engine, which offers 240-260 hp and 660 lb.-ft. of torque. The B6.7 features upgrades that allow for extended engine maintenance intervals, including longer oil drain intervals, more time between fuel filter changes, and a maintenance-free crankcase ventilation filter.
As part of its safety features, the L Series is equipped with electronic stability control, a collision mitigation system, lane departure warning, active cruise control, and a driver’s seat belt sensor. To maximize functionality, new wheelbase options and extended cab and crew cab configurations are available on the L Series.
Driver comforts: The re-engineered Hino L Series interior includes automotive-grade finishes built with commercial-use durability and increased functionality. It also features new steering wheel controls, a large 7-inch LCD multi-information display, more storage, and increased legroom for drivers who work in their cab.

The TX-12 is an on-highway transmission that features lightweight and robust construction. The new TX-12 Pro offers enhanced capabilities for vocational and select off-highway applications. The 12-speed gear set provides wide ratio coverage, allowing for maneuverability around job sites. Both Paccar TX-12 transmissions seamlessly integrate with the Paccar PX-9 for efficiency and drivability.
Improved efficiency: In addition to new Paccar Powertrain offerings, Kenworth will offer new aerodynamic roof cap and side extender options for its T180, T280, T380, and T480 models. According to the OEM, these offerings reduce drag and improve overall fuel efficiency, and they are also available for day cab Class 8 models, including the T680, W990, and T880.
