BMW is one of the oldest and most famous car brands globally. Founded in Munich in 1916, the company has positioned itself as the leading luxury, environmentally friendly, and safety-conscious car brand worldwide.
While more than 50 BMW models are currently produced, the general fuel capacity and consumption remain exemplary throughout the line-up.
The average BMW car has a 21-gallon fuel tank and a fuel consumption of 25 MPG. The most fuel efficient model is the BMW i3 and the BMW X5/X6 has the worst fuel economy.
A vehicles fuel consumption mostly depends on where it’s being driven. If the car is being driven in the city, expect it to consume more fuel. Conversely, when BMWs (or any other car) are driven on the highway, the consumption will be lower.
If you are confused about how many gallons your BMW tank can hold or its average fuel consumption, continue reading this article.
Average Consumption & Fuel Capacity of A BMW
Before we go through all the models separately, here’s a summary of the average fuel capacity and consumption for the available BMW cars.
| Average Fuel Capacity | Average MPG (Combined) |
|---|---|
| 21-Gallon fuel tank | 25 MPG |
BMW is a brand closely associated with speed and performance; however, its fuel economy can no longer go unnoticed.
Since BMW was founded in Germany in 1916, the company has been linked with high-quality designs, pioneering technology, and advanced engineering. Over the previous decade, BMW has heavily increased its focus on fuel economy and environmental sustainability.
BMW’s modern approach has attracted many customers while simultaneously receiving praise from the international climate community. Despite facing intensified calls for removing internal combustion cars from their lineup, BMW has managed to maintain its position as one of the world’s leading car-making companies.
If you have recently bought a BMW, it is crucial to note how economical your model will be and how big the fuel tank is.
This article will analyze each BMW model’s fuel economy ratings and associated fuel tank sizes.
Fuel Consumption & Capacity Of All BMW Models
The amount of fuel your BMW will use will impact monthly fuel costs, which has become an important consideration for car owners globally.
Each BMW model also has a separate fuel capacity, depending on the car’s design specifications. The fuel capacity is the amount of gas a car’s tank can hold at any given time.
BMW models with smaller tanks are mainly used in city traveling and school runs, while the company’s bigger models are aimed towards long-distance and frequent luxurious-style travel.
Here are all the available BMW models’ fuel capacity and consumption.
