Saf-T-Liner® C2 Jouley School Bus.
The future is just around the corner.

Thomas Built Buses has been moving the industry forward for more than 100 years. Now we’re driving it in a whole new way with Jouley, the first generation Saf-T-Liner® C2 electric bus.

Named after the joule unit of energy, Jouley is our first electric bus and a working example of not only how important electric vehicles are to us, but how important they are to Daimler as a whole. It’s emissions-free, noise pollution-free and fossil fuel-free, helping you save operating costs — and maybe even the planet. Ideal for in-town routes, Jouley is the latest chapter in our joint commitment with Daimler to providing proven, sustainable solutions today. And tomorrow.

On board for a greener, cleaner future?
