You are driving a motor vehicle with a manual gearbox. How can you reduce the fuel consumption of your vehicle?

Your selected combination is correct as both strategies help reduce fuel consumption. Switching early to a higher gear optimizes the engine's efficiency, leading to less fuel being used. Driving in a smooth, anticipatory manner also contributes, as it minimizes the need for rapid acceleration and braking, which can waste fuel. This approach aligns with German traffic regulations that promote eco-friendly driving practices. Additionally, maintaining a higher engine speed, as suggested in the third option, can actually result in increased fuel consumption, making it critical to focus on the first two choices for effective fuel savings.
