What is the fuel economy of an electric school bus?

There are several reasons electric school buses are a better choice compared to their diesel equivalent. More fuel efficient: Diesel school buses can drive at 8.20 miles per gallon, whereas an electric school bus drives at 20.87 miles per diesel gallon equivalent — making them almost 60% more energy efficient.

On average, diesel buses use 6 miles per gallon [mpg], while electric buses boost that efficiency to an equivalent of 17 mpg. Electric school buses can save more than $170,000 on fuel and maintenance throughout their lifespan.

The average bus gets between 6 and 9 mpg, depending on many factors (size of bus, wind, speed, and of course how heavily loaded). That being said, it's not usually gas mileage. The majority of buses have diesel engines. Some run on propane, and a few on gasoline, but mostly diesel.

Electric buses can save cities up to $170,000 per unit — here's how to vie for them in your area. Swapping one diesel bus for an electric one reduces human health costs by $150,000 per year. Standard diesel-sucking buses are actually some of the most eco-friendly ways to travel when compared to planes and cars.

What Are The Disadvantages Of Electric School Buses? The two biggest disadvantages are cost and range.

MORE DETAILS

It's cheaper to run and maintain an electric bus. Fueling a bus with electricity is only about a third of the cost of fueling it with gas, which saves a considerable amount of money over time. Electric buses also have fewer regular maintenance costs—because they don't run on fuel, there's no need for oil changes.
