Exploring the Latest Kenworth T680E and T880E
Our visit to the PACCAR Technical Center in Mount Vernon, Washington, allowed us to experience Kenworth’s newest battery-electric models: the updated T680E and the all-new vocational T880E.
Even in wet conditions, both trucks handled full loads effortlessly. The electric models showcased immediate torque and smooth acceleration, highlighting the distinction between electric and diesel engines, accompanied by the unique quietness inside the cab.

Designed for Heavy-Duty Performance
Despite the differences, Kenworth aimed to ensure the trucks deliver a familiar feel compared to their diesel counterparts. Instead of traditional engine braking, adjustable regenerative braking is utilized to decelerate the electric trucks while also recharging the battery, enabling longer drive times between charges.
At ACT Expo in Anaheim, California, we met with Kenworth during the official launch of the T680E and T880E. Nick Harker, Kenworth’s assistant chief engineer, highlighted the focus on flexibility in their latest battery-electric vehicles. “We have on-highway offerings for regional haul and pickup and delivery, as well as the industry-first vocational battery-electric Class 8 vehicle,” he explained.
Innovative Powertrain and Range
Central to both trucks is the PACCAR ePowertrain platform, tailored explicitly for heavy-duty electric applications, offering continuous power ranging from 365 to 470 HP, peaking at 605 HP and generating 1,850 lb.-ft. of torque. The driving range can reach up to 250 miles between charges, depending on the battery configurations, with a maximum capacity of 625 kWh.
Vocational Capabilities with Electric PTO
The T880E is designed for versatility, supporting electric power take off (PTO) options for various vocational tasks. Fleets can choose from e-PTO power of 25kW or 150 kW (approximately 33 and 200 HP, respectively), making it suitable for construction and utility projects. “This truck is highly adaptable regarding frame layouts,” Harker noted. “We’re working to provide cost-effective solutions across multiple vocations.”
Real-World Testing Validated
While the powertrain is new, the chassis and cab designs remain tried and tested. Harker asserted, “Our chassis and cab are reliable; we are simply introducing a new powertrain.” Moreover, Kenworth has rigorously validated the new powertrain, accumulating over 500,000 miles testing the trucks in various climates and altitudes. Production is set to commence later this year.
