Powertrains Replace Diesel Engines on Existing Freightliner Trucks

DALLAS, TX / ACCESSWIRE / June 24, 2024 / Principal Solar, Inc. (OTC Pink:PSWW) ("Principal" or "the Company"), a strategic investor in and acquirer of technologies that support next-generation opportunities in traditional, renewable, and clean energy sectors as well as an investor in and operator of undervalued petroleum-producing properties, today announced that its Royalty Agreement Partner, eTruck Transportation, expects to begin producing powertrains that turn Class 8 diesel trucks into hybrid battery-electric vehicles by the end of 2024.

The powertrain systems are already available for order, and eTruck plans to start commercial production by the end of the year, eTruck company President Russell Knudsen told Transport Topics.

Omaha, Nebraska based eTruck currently offers an option for a Class 6 retrofitted battery-electric truck, with 23 powertrains sold so far, said Knudsen, whose wife, Judith Knudsen, is the CEO of the family-owned company.

Previously, the Knudsens owned Rage Exotic Vehicles, an exotic vehicle designer and manufacturer. Before that, Russ Knudsen was president of Knudsen Automotive, which designed specially prepared vehicles for television series and movies, such as "Miami Vice" and for manufacturers including General Motors.

The target audience is much larger for eTruck, with Knudsen telling TT the company was offering a solution any fleet could buy into.

An electric drive system replaces the diesel engine for the company's Class 6 truck, leaving the transmission and driveshaft in place. An electric motor is attached to the transmission, battery packs are bolted on the outside of the frame rails, and a control system is installed in the truck.

With the retrofitted Class 8 hybrid truck, the electric motor and battery packs remain, but a small diesel engine is added, with a range extension option available that involves a gasoline-powered generator for recharging the batteries, said Knudsen.

"It is very simple. That is one of the things that is going to make this very popular," said Knudsen, adding: "We don't have any competition, and we're not competing with anyone else. Someone that wants a new truck is going to buy a new truck. But for someone who can't afford that, we can offer them three for the price of one new truck."

Rolls-Royce is set to supply the small, twin-turbo turbocharged diesel engine for the hybrid truck, and Siemens will supply recharging system components. Knudsen said eTruck is still in negotiations with battery suppliers.
