You are driving a motor vehicle with a manual gearbox. How can you achieve efficient fuel consumption?

The combination you selected is correct because proper tire inflation pressure and an even driving style with low engine speeds are both essential for achieving efficient fuel consumption.

Maintaining the correct tire pressure ensures that the vehicle has better traction and reduced rolling resistance, which leads to less fuel consumption. An even driving style with low engine speeds avoids rapid acceleration and deceleration, which are inefficient and can significantly increase fuel usage.

The option that was missed, which suggests changing gears upwards as late as possible when accelerating, is not advisable for fuel efficiency. This practice can lead to higher engine speeds and increased fuel consumption. Instead, shifting up earlier promotes lower engine speeds, which is more efficient.

Understanding these combinations helps not only in following best practices for fuel efficiency but also aligns with the German traffic regulations, which emphasize eco-friendly driving behaviors.
