The Thomas Built Buses Saf-T-Liner C2 Jouley (also called the Saf-T-Liner eC2) is a battery-electric-powered type-C school bus. It is Thomas' first fully-electric bus and was launched at the 2017 National Association for Pupil Transportation Conference and Trade Show in Columbus, Ohio. Production was expected to commence in 2019.[1]

The pre-production C2 Jouley was equipped with the PowerDrive™ 7000ev powertrain from Efficient Drivetrains, Inc. It could travel up to 120 miles with an option for an extended range. 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.[1]

For the 2018 IAA trade show, the C2 Jouley received a revised grill and headlights. Like Freightliner's other electric vehicles, the grill is gloss black with chromed strips and blue LED accents. The headlights are tinted.

In September 2018, Proterra announced that they were collaborating with Daimler to integrate their technology into Daimler vehicles.[2] The production C2 Jouley uses Proterra’s drivetrain and battery systems. With a 60 kilowatt J1772 charger, the bus can be fully recharged in approximately three hours and operate for up to 134 miles (initially 120 miles). The Proterra-powered C2 Jouley made its debut at that year’s National Association for Pupil Transportation Conference and Trade Show.[3]

The announcement of their first large order for the C2 Jouley came in December 2019 when Thomas announced that they were selected as the provider 50 electric school buses for the initial phase of Dominion Energy’s electric school bus replacement program in Virginia.[4]
