Sun Tran adds 15 new CNG buses to fleet

November 19, 2020. Sun Tran introduced 15 new buses into its fixed-route service in November. The buses utilize Compressed Natural Gas (CNG) to improve air quality.

The 40-ft. GILLIG CNG buses produce lower emissions than standard fueled vehicles and older CNG vehicles, helping improve air quality in the community. The new buses replaced older biodiesel fueled buses, putting the average fleet age to 7.7 years.

“These new CNG buses maintain Sun Tran’s commitment to utilize clean fuel technology in a cost-effective manner,” said General Manager of Sun Tran, Steve Spade. “As we continue to test the first electric bus in Tucson, the CNG buses allow Sun Tran to further reduce emissions and improve air quality.”

Sun Van recently put into service 21 new Ford E-Series Cutaway Vans into its paratransit fleet. The new vehicles replace aging vans to improve the overall safety and reliability of service to Americans with Disabilities Act (ADA) passengers.

And on December 1, 21 more E-Series Cutaway Vans will go into revenue service, decreasing the average fleet age to 2.36 years.

Each 22-foot vehicle can accommodate nine (9) passengers and features a longer wheelbase (138 in.) than current Sun Van vehicle models. The longer wheelbase increases floor space inside the vehicle, allowing better maneuverability into the wheelchair securement area for passengers.

Since 2006, 100 percent of Sun Tran’s fleet has utilized clean fuel technology. The current breakdown of Sun Tran’s fleet, and which fuel type each bus is using consists of the following: 128 B5 biodiesel; 83 Compressed Natural Gas; 11 Hybrid-electric/biodiesel; and 1 Electric.
