Diesel engines almost never need to be replaced during the life of a school bus. Unlike many alternative fuel engines, diesel engines don't need to be upfitted or replaced multiple times during their lifecycle, saving time, money and hassles.

The Blue Bird school bus manufacturer has committed its lineup of yellow young human-haulers to a new engine: the 7.3-liter gasoline V8 found in the 2021 Ford Super Duty. That's more displacement than the outgoing model, but it's the finer details that should help keep these new buses running for generations to come.
Diesel powers over 90% of all school buses thanks to its combination of fuel safety, energy efficiency, reliability, durability, established fueling and maintenance network, range and operational flexibility, secondary markets and low acquisition and operating costs.
Taken as a whole, urban transit averages 14.1 mph, less than half the speed of driving in most cities (and slower than many cyclists). This doesn't count the time spent getting to and from transit stops, waiting for transit vehicles, or transferring from one to another, all of which make transit even slower.
Over the long haul, newer diesel engines will last 15-20 years in a fleet, while a gasoline engine may need to be replaced once or even twice during the life of a school bus. “All of these are important for fleet managers to stop and consider when choosing a new school bus,” says Hedgecock.
The seats are built for the average man . Women, children and anyone bigger than average won't be as comfortable. You will also find that most passenger vehicles are built for average sized males. Female anatomical considerations are rarely addressed.
Besides road debris, much of the noise you hear inside a bus is rattling from the metal panels that vibrate and shake as you drive along. To reduce this clanging, you can deaden the metal, which will reduce the vibrations - and you can't have structural sound without vibrations.
Diesel. Among other types of fuel transport vehicles use, diesel fuel is a popular choice for those working with larger-capacity vehicles such as buses, vans, trucks, and boats.
Some alternatively fueled engines like propane or gasoline may need to be replaced two to three times during the normal lifecycle of a school bus. Clean-diesel engines, on the other hand, are built to last 15-20 years.
