Thomas' first fully-electric bus was launched at the 2017 National Association for Pupil Transportation Conference and Trade Show in Columbus, Ohio. The pre-production C2 Jouley was equipped with the PowerDrive™ 7000ev powertrain from Efficient Drivetrains, Inc., which provided 100-160kWh of battery energy and a range of up to 100 miles. With a standard J1772 charger, the bus could be fully charged in approximately eight hours (nominal charge of four to six hours). Integrated exportable power enabled the transfer of stored energy onboard the bus back into the electrical grid.
The nickname "Jouley" derives from "Joule" (the unit of energy).
