Propane is the world's most popular clean-burning alternative fuel. In North America we have an abundant domestic supply. And it's about 40% less expensive than a gallon of gasoline or diesel on a btu basis. So it just makes sense to consider propane for school bus fleets. Setting up the infrastructure is an easy and relatively low-cost proposition.


You can expect exceptional power and quiet operation from your Thomas Built Buses propane-fueled Saf-T-Liner® C2 bus. And this bus is available with popular options like wheelchair lifts and air-conditioning.
