Why Are Gas Tanks Placed on Different Sides of the Car?

Ever noticed that some cars have their gas tank openings on the left side, while others are on the right? You might have wondered why manufacturers don’t just pick one side and stick to it. The truth is, the placement of gas tanks—and more specifically, the fuel filler cap—is a thoughtful decision influenced by safety, design, regional driving customs, and manufacturing considerations.

Let’s dive into why gas tanks are placed on different sides of the car and what factors influence this choice.

1. Regional Driving Norms

One of the biggest reasons gas tanks are located on different sides is tied to which side of the road people drive on.

• In countries where drivers use the right side of the road (like the USA, Canada, and most of Europe), gas tanks are often placed on the left side of the car. This allows the driver to pull up closer to the gas pump, which is typically positioned on the side of the road. It’s also safer since the driver can exit the car away from traffic when refueling.
• Conversely, in countries where drivers use the left side of the road (like the UK, Australia, and Japan), gas tanks tend to be on the right side for the same reasons.

2. Safety Considerations

Safety plays a vital role in the location of gas tanks and filler caps.

• Placing the gas tank on the side away from oncoming traffic reduces the risk of accidents or injuries during refueling.
• It also keeps the driver and passengers away from traffic flow when they get out to fill the tank, which enhances personal safety.

3. Manufacturing and Design Factors

Sometimes, the choice boils down to vehicle design and manufacturing convenience:

• The internal layout of a car—such as where the engine, exhaust system, or battery is located—can influence which side is more practical for the gas tank.
• Some manufacturers place the gas tank on the side that balances the vehicle’s weight distribution for better handling.
• In cases where automakers sell the same car model in multiple countries, they may design different versions with filler caps on different sides to suit regional preferences.
