school buses




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 offer drivers a pleasant riding and operation experience. As many satisfied customers can affirm, propane is a safe, clean and affordable alternative fuel, that features many operational and cost-saving benefits.


Safe Alt Fuel.

Propane bus features:

  • Safe for kids & environment
  • Propane is virtually odorless & colorless
  • Propane does NOT ignite easily
  • Fuel tanks are thick & durable
  • Tank mounting is strong & secure
  • Fueling is safe & easy

Our buses’ engine systems are fitted with safety devices and shut-off valves that function automatically if the fuel line ruptures, and all lines and hoses are protected to prevent damage from loose cargo which could be encountered in the vehicle interior.

Propane is a very safe alternative fuel – both for the environment and the children that ride in our propane-powered school buses. 

Propane is 270 times more compact as a liquid than as a gas, making it safe and economical to store and transport. Wearing gloves and goggles is recommended when refueling (which is also recommended for CNG, diesel and gasoline fueling).

Because it is released from a pressured container as a vapor, propane autogas can’t be ingested like gasoline or alcohol fuels. To put it simply, igniting propane gas in the air calls for very specific things to occur: 1)The mixture of propane/air must contain 2.2 percent to 9.6 percent propane vapor. Any more, or any less than that, and the propane will not ignite, 2) The source of ignition must reach 940 degrees Fahrenheit. In contrast, gasoline will ignite at only 430 to 500 degrees Fahrenheit.

Propane autogas fuel tanks are 20 times more puncture-resistant than typical diesel or gasoline tanks. They are made from carbon steel, include vapor-tight enclosures around all lines and fittings, and are manufactured with an Overfilling Prevention Device (OPD) that ensures the fuel volume will be able to adjust with temperature variations. There is also a pressure release device in every tank should the pressure rise beyond safe levels.

Even in 20g frontal impact, or 8g side or rear impact (which is twice the requirement specified in NFPA58), the propane tank will remain securely in place. It is also mounted between Blue Bird’s durable frame rails, which creates additional safety.

You Smell That?

NOT unless you have a LEAK...and that is by design.

In its natural form, propane has no scent, but a scent has been added (ethyl mercaptan) and is necessary to alert you that there is gas in the air. You will NOT smell propane as you drive down the road in this bus, unless there is a leak. This is for your safety.

low NOx emissions.

The Vision Propane is built better. Our quality shows from the ergonomic driver’s cockpit to the industry’s largest bumpers for added safety and protection.Quality is built-in to each bus we produce. 

A few examples are…

  • Improved window seals for ultra-smooth operation,
  • Easy windshield replacement, and
  • An engine compartment that’s readily accessible.


We Stand Behind Our Quality with a standard 5-year, unlimited mile warranty on our Vision Propane Engine and Fuel Systems

The Vision Propane’s Ford engine, paired with the Ford 6R140 transmission and ROUSH CleanTech fuel system, is certified to the low NOx level of 0.05 g/bhp-hr.

The performance of the engine relies on the transmission it works with. This is why Blue Bird has chosen to pair the Ford 7.3L engine with the proven 6R140 Ford transmission. This transmission was designed for the Ford 7.3L engine in order to deliver the best ratio of power and fuel economy.

It is cleaner by composition, not complication.

Further adding to the quality of the Propane bus, there are less parts on a propane bus versus other fuel types, making maintenance costs lower while improving the lifespan of existing bus parts. Because liquid propane has less buildup then other fuel types, your parts are cleaner, longer.

Blue Bird’s purpose-built chassis, specifically designed for bus applications, blends 90 years of innovation with unmatched value.

We make it easy to maintain with our superior technical training programs. ROUSH CleanTech also provides ongoing support through on-site or web-based technician training. To set up training, please contact your local Blue Bird dealer.

We pay attention to the details that deliver performance, and consistently explore ways to better our products. It’s part of Blue Bird’s continuous improvement culture.


FORD 7.3L V8




Engines fueled by propane autogas require:

  • Less oil by volume than diesel
  • No additional diesel emission fluids
  • No extra valve adjustments

The Vision Propane bus delivers economical training and easy maintenance that saves time because of:

  • Simplified emissions system
  • Proven performance
  • Simple service strategy

Ready to Roll?

YES! No costly after-treatments needed for EPA.

No costly diesel after-treatment systems are required to meet Environmental Protection Agency requirements with the propane engine. And, the cleaner-burning fuel translates to cleaner parts and longer life for the engine.

Total Cost of Ownership

Calculating the TCO allows you to select a bus with confidence, because you will know you are getting the best return on your investment.

TCO is determined based on…Initial purchase price, taking into account:

    • Fuel costs over time
    • Maintenance costs over time
    • Projected bus lifespan

With these factors in mind, the Blue Bird Propane Vision bus is the clear winner when it comes to TCO.
