Saf-T-Liner® HDX CNG

Better drivability and a good choice for the future.


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 launched the Saf-T-Liner HDX CNG more than 10 years ago. Since then, we've put more than 1,000 CNG buses on the road.

Versatile, customizable, and 2010 emissions-ready.

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 of your school equipment, and 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.
