What is the average mileage of a school bus?

What is the average mileage of a school bus? 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.

What engine is in most buses?

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.

What is the MPG of a full size bus?

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.

Do school buses get good gas mileage?

How Much MPG Does a School Bus Get? Admittedly, the average school bus's fuel economy is what you'd expect of a bus—not great. According to the Alternative Fuels Data Center, school buses get an average fuel economy of just 6.02 miles per gallon (MPG).

How many MPG does an old school bus get?

Type 'A' buses on the Ford chassis with the 460 gas V-8 got 5-9 MPG with the honest average closer to 5 MPG than to 9 MPG. The Type 'A' buses on the Chevy/GMC chassis with the 6.2L diesel V-8 were underpowered, slow, noisy, and not very fuel efficient. 10-14 MPG. The engines were pretty stout but underpowered in a bus.

How many miles can a bus engine last?

My rule of thumb when I was shopping for a bus was a well maintained gas bus with under 100,000 miles or a well maintained diesel bus with under 200,000. In theory, a well maintained diesel engine can practically run forever. I drive city buses. They often have multiple million miles before they retire them.

How many miles per gallon does a Thomas school bus get?

The Thomas C2's overall average mileage for the four test segments was 9.2 miles per gallon; competitor product's overall average was 7.6 miles per gallon.

What is the most common bus engine?

Propulsion. The most common power source since the 1920s has been the diesel engine. Early buses, known as trolleybuses, were powered by electricity supplied from overhead lines.

Are gas or diesel buses better?

A diesel engine requires less fuel to produce the same output as a gas engine. A conventional gas engine operates via a spark ignition system, which burns more fuel than a diesel engine's combustion system. As a result, diesel buses are more fuel-efficient per gallon and burn less fuel while idling.

How long do school bus diesel engines last?

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.

What is the most efficient bus engine?

Period. Why? Diesel is the most fuel-efficient engine type on the market. Diesel outperforms other fuels in operating range.

How long do bus diesel engines last?

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.

How big is the gas tank on a bus?

A full size bus holds about 250 gallons of fuel. This make the range about 625 to 750mpg depending on the style of bus. The longest range electric bus made by Proterra was driven 1,101 miles on one charge. Most electric buses on the road today get 100- 250 miles to a charge.

Do buses use a lot of gas?

According to the U.S. Department of Energy, the average school bus travels 12,000 miles per year ⁴. At the average school bus mpg, that means a single school bus would use about 1,993 gallons of fuel annually.
