Technology: Rand McNally’s video telematics now running on its new vehicle platform
The zero-emission Kenworth K270E Class 6 and K370E Class 7 battery-electric vehicles are now available for order from Kenworth dealers in the U.S. and Canada.
The electric powertrain is available with high-density battery packs of 141kWh and 282kWh that deliver up to 100- and 200-mile range, respectively, with zero emissions, Kenworth says, adding the electric vehicles utilize a DC fast-charging system capable of fast re-charge in as quick as one-hour, which make the Kenworth K270E and K370E cabovers ideal for local pickup and delivery, as well as short regional haul operations. End-of-shift and overnight AC charging also is offered.
Kenworth battery-electric vehicles offer two direct-drive motors rated at 355 hp and 469 hp, depending on application. The company says this design provides enough torque to start the load from a stop on a 20% grade and the power to maintain 40 MPH on a 6% grade while fully loaded. Regenerative braking in stop-and-go city conditions recharges the batteries and extends brake life.
All of the components necessary to run the e-powertrain, as well as HVAC and e-PTO, are located in one power cradle under the cab, the space typically occupied by a diesel engine. Kenworth says the system configuration also optimizes weight distribution with batteries mounted outside and air tanks mounted inside the frame rails. A quiet e-compressor maintains pressure in the air system, the company adds.
Kenworth and Dana Inc. are collaborating on the Kenworth K270E and K370E electric vehicles.
Available wheelbases offered are 206 in. (24-ft. box bodies), 218 in. (26-ft. box bodies) and 274 in. (30-ft. box bodies).
