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

The correct combination for reducing fuel consumption involves two aspects: shifting to a higher gear early and employing an anticipatory driving style.

1. Shifting early to the next gear helps keep the engine running at optimal efficiency, which generally means lower fuel consumption. In Germany, this aligns with eco-driving principles that encourage efficient vehicle operation.

2. An anticipatory driving style helps maintain a steady speed, which reduces the need for rapid acceleration and braking. Frequent speed changes can lead to higher fuel consumption, contradicting energy-saving practices.

Driving at high engine speeds, as mentioned in the third option, typically increases fuel use significantly and goes against the idea of fuel efficiency. Therefore, avoiding this practice is crucial for both cost savings and environmental considerations.
