A Smart Clean Reliable Choice



Propane-powered buses offer a range of benefits, making them an appealing choice for sustainable public transportation. Firstly, they emit significantly lower amounts of harmful pollutants compared to their diesel counterparts, which helps in reducing air pollution and contributing to cleaner air in urban environments. Additionally, propane is cost-effective, often less expensive than diesel or gasoline, which can lead to substantial savings in fuel costs over time. 

Propane buses also tend to operate more quietly, enhancing the comfort for passengers and reducing noise pollution in the community. These features, combined with propane’s reputation for reliable performance in various weather conditions, make propane-powered buses an environmentally and economically smart option for public transit systems.



With over 20,000 sold, Blue Bird’s 5th Generation Vision Propane bus is engineered to deliver fuel and maintenance cost-saving results, as well as offering drivers a pleasant riding and operating experience.

Powered by the reliable Ford 7.3L engine, this bus is designed and engineered to operate on propane featuring the ROUSH CleanTech Propane Fuel System. As many satisfied customers can affirm,  propane buses provide safe, clean, and reliable transportation without an expensive investment. 

Affordable Infrastructure

The infrastructure for propane is affordable and scalable. Propane pumps operate similarly to diesel and gasoline, making them easy for anyone to use. Many times, your local propane provider will install a fueling station on site for low or no cost with a longterm propane contract. If an onsite fueling station isn’t an option, there are thousands of propane autogas fueling stations in the U.S., with stations in every state.

Low-Emissions Engine 

Buses that run on propane emit fewer greenhouse gases and total hydrocarbon emissions and virtually eliminate particulate matter. The 7.3L Ford engine, paired with the ROUSH CleanTech fuel system, is certified to the standard low NOx level of 0.02 g/bhphr, making it 90% cleaner than EPA’s most stringent heavy-duty engine standard. In fact, it takes 10 Blue Bird Vision Propane buses to emit as much NOx as one clean-diesel bus.



Blue Bird’s commitment to
alternative fuel safety and
innovation has been steadfast
since the introduction of our first
generation of propane-powered
buses in 1993.

Now on our fifth generation, we continue to improve and introduce innovations that lead the market with our proven partnership with ROUSH CleanTech and Ford.


Ford 7.3LV8 Engine

Each Blue Bird Vision Propane school bus comes equipped with a 7.3L V8 Ford engine and ROUSH CleanTech propane fuel system. Ford’s 335-horsepower 7.3L engine is compact, powerful, and easy to maintain. This bus retains equivalent horsepower, torque, towing capacity, and warranty coverage as its gas and diesel counterparts.

Total Cost of Ownership

When configuring a bus, one should consider the total cost it will take to operate and fuel the vehicle throughout its lifetime. The total cost of ownership (TCO) for propane buses is the lowest of any fuel type because the fuel is produced domestically, bringing it to a lower cost than typical oil-based fuels. There are also fewer parts to maintain, which lowers the overall cost of maintenance. That’s why Blue Bird has developed a (TCO) calculator to show you the savings.

This calculator helps you determine which fuel type will be less expensive to maintain over the course of its running lifetime. Most often, propane is the clear winner for providing the lowest TCO of any fuel type.
