While Type A buses may not have the same passenger capacity as larger buses, they often have better fuel efficiency.
On average, Type A school buses can get around X miles per gallon.
Type B
Type B school buses, also referred to as “transit-style buses,” are characterized by their forward-control design and usually have a flat front or a hood. These buses are larger than Type A buses and can accommodate more passengers. Type B buses are commonly used for regular student transportation.
In terms of fuel economy, Type B buses typically get around Y miles per gallon.
Type C
Type C school buses, also known as “conventional buses,” are the most common type of school bus on the road. These buses have a distinct appearance with a separate body and chassis and a flat front. They can carry a substantial number of passengers and are often equipped with a wheelchair lift.
Type C buses tend to have a lower fuel economy compared to Type A and Type B buses. On average, Type C school buses can achieve roughly Z miles per gallon.
Type D
Type D school buses, also called “transit-style buses,” are the largest school buses available. These buses have a full-height, rear-engine design, and they can carry a significant number of passengers.
Due to their size and weight, Type D buses typically have a lower fuel economy compared to other types of school buses. On average, Type D school buses can achieve approximately W miles per gallon.
It’s important to note that these fuel economy numbers are averages and can vary depending on factors such as driving conditions, maintenance, and load.

Factors Impacting School Bus MPG
Bus Size and Weight
The size and weight of a school bus play a significant role in determining its miles per gallon (MPG) rating. Generally, larger buses tend to have lower MPG compared to smaller ones. This is because larger buses have more carrying capacity and require more energy to move.
Additionally, the weight of the bus itself also affects fuel efficiency. Heavier buses require more fuel to operate, resulting in lower MPG.
Engine Type
The type of engine used in a school bus can greatly impact its MPG. Most school buses are powered by diesel engines, which are known for their fuel efficiency. Diesel engines are designed to provide high torque at low speeds, making them ideal for stop-and-go traffic situations common to school bus routes.
On the other hand, buses with gasoline engines may have slightly lower MPG compared to their diesel counterparts.
Age and Condition
The age and condition of a school bus can also affect its MPG. Older buses tend to have lower fuel efficiency due to wear and tear on the engine and other components. Regular maintenance and proper upkeep can help improve MPG by ensuring that the bus is running at its optimal level.
It is worth noting that newer buses often come equipped with more advanced technology and fuel-saving features, which can contribute to higher MPG ratings.
Driving Conditions and Routines
Driving conditions and routines also impact the MPG of a school bus. Buses that operate in urban areas with frequent stops and starts may have lower MPG compared to those that primarily travel on highways. Additionally, driving habits and routines can affect fuel consumption.
Aggressive driving, such as rapid acceleration and braking, can decrease MPG. On the other hand, adopting fuel-efficient driving techniques, such as maintaining a steady speed and avoiding excessive idling, can help improve MPG.
It’s important to note that the MPG of school buses can vary depending on these factors. While there is no one-size-fits-all answer to how many miles per gallon a school bus gets, considering these factors can provide a better understanding of the potential fuel efficiency of a school bus.
