Thomas Built Buses, Inc. today introduced the Saf-T-Liner® C2 propane school bus equipped with the new Driveforce 8.8L LPG engine produced by Powertrain Solutions Integration (PSI). The new engine offers excellent torque for hill-climbing power while maintaining lower engine speeds resulting in improved fuel economy.
“We are happy to offer this new propane option for our customers,” said Caley Edgerly, president and CEO of Thomas Built Buses. “As our continued commitment to stand behind the latest in safety and efficiency technologies in our industry, this engine, which was designed specifically for propane-fuel, offers customers uncompromising power and performance with maximum fuel efficiency and cleaner emissions.”
The Thomas Built Buses Saf-T-Liner C2 propane equipped with the 8.8L LPG engine can be paired with the Allison 2500 or 2550 PTS transmission. Customers also may choose a 70- or 100-gallon fuel tank configuration. The propane-fueled Saf-T-Liner C2 is California Air Research Board-certified in all 50 states.
Production of the new propane school bus will begin early August 2019.
