Blue Bird Will Produce Propane, Gas School Buses Using Ford 7.3L Godzilla V8: Video

This spring, long-time school bus builder Blue Bird will begin production of its propane and gasoline Vision school buses integrating the all-new Ford 7.3L Godzilla V8 engine and a purpose-built fuel system designed specifically for school bus applications. The advanced fuel system technology was developed by Roush CleanTech, the same company that has manufactured over 30,000 propane and gasoline fuel systems for Blue Bird buses equipped with the Ford 6.8L Triton engine.

The 2022 Blue Bird Vision with the propane and gasoline Ford 7.3L Godzilla V8 engine features a best-in-class combination of horsepower and torque. In addition, the compact and lighter-weight 7.3L engine should achieve improved fuel economy over the 6.8L engine.

“The exclusive partnership between Blue Bird, Roush CleanTech, and Ford continues to flourish as we launch Ford’s new engine with cutting-edge fuel systems in our Vision and Micro Bird school buses,” said Phil Horlock, president and CEO of Blue Bird Corporation. “We’ve already heard excitement from our customers about this compact, more powerful, and easier-to-maintain engine with better fuel economy.”

In addition to the all-new engine, the new propane and gasoline Vision incorporate newly engineered routing of the wiring and fuel lines, centered between the frame rails for improved quality, simplicity of maintenance, and product longevity. The buses also feature a new front grille design.

Ford’s new 350 horsepower 7.3L engine is narrower than the previous 6.8L, allowing more room for service work. Innovations for the fuel system, known as Gen 5, include stronger and lighter forged fuel rails and unique routing that keeps the engine-fuel distribution well organized.

“Backed by 45 years of Roush engineering, the Gen 5 is the next advancement in powertrain technology, delivering lots of power in a smaller package,” said Todd Mouw, president of Roush CleanTech. “Our advanced fuel system integrates seamlessly with the new Ford engine to give school bus customers the most cost-effective product on the market.”

Roush CleanTech’s Gen 5 propane engine is certified to California Air Resources Board’s optional low nitrogen oxide emissions standard of 0.05 grams per brake horsepower-hour (g/bhp-hr). The Gen 5 system reduces nitrogen oxides and greenhouse gas emissions, which helps optimize fuel efficiency and can operate on renewable propane, which further reduces emissions and carbon levels. The engine is designed to meet current and future emissions requirements.

Brett's lost track of all the Fords he's owned over the years and how much he's spent modifying them, but his current money pits include an S550 Mustang and 13th gen F-150.

    I sure hope for BLUEBIRD’s sake that they got this new engine right. The grand old V10 served long and well. There are many of those propane V10 powered VISIONS around here. I will miss that unique smooth exhaust note that those 6.8L’s make.

    Well, that’s one way to get kids to schools quick “ Powered by Ford 7.3”

    Does that thing have TWO alternators?

    There’s also some speculation that BLUEBIRD may drop the CUMMINS 6.7 in favor of the FORD POWERSTROKE. In this model. The CUMMINS is a great long proven engine so that may be a mistake.
    It would make sense though since the PS and 7.3 use the same transmission where the CUMMINS uses an ALLISON. We’ll see.
