Thomas Built Buses Unveils New Second-Gen Saf-T-Liner C2 Jouley Electric School Bus

Thomas Built Buses has introduced the new second generation of its Saf-T-Liner C2 Jouley electric school bus, emphasizing enhanced efficiency, improved performance, and simplified maintenance. Originally launched in 2017, the updated Jouley incorporates significant technological upgrades and design changes.

At the core of the second-gen Jouley is the 14Xe eAxle from Accelera, a zero-emissions division of Cummins. This compact unit integrates the motor, transmission, brakes, and rear-drive gear directly on the rear axle, eliminating the need for a traditional driveshaft. The eAxle provides smoother rides, improved torque, and better acceleration while reducing weight and complexity, making the bus more efficient and easier to service.

The bus also features an 800-volt Proterra battery, enabling it to handle challenging terrains, steep inclines, and high-demand systems like air conditioning and heating without sacrificing performance. The higher voltage also contributes to faster acceleration and greater adaptability to diverse routes, from flat roads to mountainous regions.

Maintenance improvements include a simplified eAxle design with fewer moving parts, a new floor panel providing direct access to high-voltage connectors, and a relocated heating loop surge tank for easier servicing. These updates aim to minimize downtime and ensure quicker returns to operation.

With a 219-inch wheelbase, the updated Jouley can accommodate up to 60 passengers, addressing the needs of school districts for increased capacity. Its shorter eAxle also improves maneuverability, making the bus suitable for tight parking and servicing spaces.

Driver experience is enhanced with a modern LCD digital dashboard offering detailed diagnostics and operational data in an intuitive format. Over-the-air software updates will allow ongoing feature enhancements without requiring physical hardware changes.

Production of the 219-inch wheelbase version of the Jouley has commenced at Thomas Built’s factory in High Point, North Carolina, with additional wheelbase options expected in 2025.
