Electric hybrid semi-truck

Edison Motors, a Canadian startup, developed a diesel-electric hybrid semi-truck. Topsy is a working prototype that uses a CAT C9 diesel engine to power a generator. The generator charges the batteries and supplies power to the electric drive axles. This setup allows long hauls without relying on charging stations—perfect for remote areas. Equipped with regenerative braking, Topsy recaptures energy when going downhill. It packs two electric motors, one per axle, delivering 700-800 hp and up to 85,000 lb-ft of torque. Edison Motors has road-tested Topsy, but their production model, the Series L, has yet to be announced. Would you drive a hybrid semi? Learn more at edisonmotors.ca
