Eco-Friendly Transportation Made Easier

A bigger bus doesn’t always mean a bigger carbon footprint. At Arizona Bus Center, we’re committed to providing options for an eco-friendly future. As an added benefit, these fossil fuel alternative buses can provide your organization with fuel savings too!

The models are built to operate on compressed natural gas (CNG) or propane to give you flexibility in finding the right green bus for your business or organization.

Compressed Natural Gas (CNG) is a fossil fuel substitute for gasoline and diesel. It’s cleaner and more environmentally friendly.

Based on the design of our original Saf-T-Liner® HDX, Thomas Built Buses launched the Saf-T-Liner® HDX CNG nearly 20 years ago. Since then, we’ve put more than 2,000 CNG buses on the road.


With a tough build and the largest windshield in its class for better driver visibility, it’s no wonder the HDX is the long-route leader. The HDX can take on all your school equipment, up to 90 passengers, and it is completely customizable to satisfy your demands. Add-ons like air conditioning, pass-through underbody storage, and coach-style seating keep everyone comfortable, no matter the distance.

Many of us are concerned about contributing to a healthier earth. For Thomas Built Buses, that means fossil fuel alternatives. Back in 1969, Thomas Built Buses’ parent company, Daimler, introduced the first hybrid bus: the Mercedes OE302 hybrid electric. Today, Daimler remains the world leader in green technology.
