Why are Gas Tanks Located on Different Sides in Various Cars?

Exhaust-System Layout Can Matter The exhaust system is another important consideration. Engineers need to route exhaust components beneath the vehicle while managing heat and maintaining appropriate separation from fuel-system components. The fuel filler and associated plumbing therefore have to be designed as part of the entire vehicle system. This doesn’t mean the fuel door must always be opposite the exhaust. In fact, you’ll find vehicles with different arrangements. It’s simply one of the many engineering factors considered when deciding where the filler system should go. Manufacturing Can Influence the Decision Automakers also have to think about how efficiently a vehicle
