What increases the fuel consumption of your vehicle considerably?

Heated seats and air-conditioning are known to significantly increase fuel consumption because they require additional energy from the vehicle's engine. When these systems are in use, the engine works harder, which translates to higher fuel usage.

It’s important to recognize that both options contribute to increased consumption, as outlined in regulations regarding fuel efficiency and environmental standards in German traffic laws. Neglecting any of the contributing factors can lead to misinformed decisions about vehicle operation and fuel efficiency, underscoring the need to consider all relevant aspects when evaluating factors affecting fuel consumption.
