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

The selected combination of answers is correct because both proper tyre inflation and an even driving style contribute significantly to fuel efficiency. Proper tyre inflation ensures that the vehicle has reduced rolling resistance, improving fuel economy. An even driving style with low engine speeds minimizes fuel consumption and keeps the engine working efficiently.

In contrast, changing gears upwards too late can lead to higher revs and increased fuel usage, which is why it is not part of the efficient fuel consumption practices. Following these principles aligns with recommendations found in guidelines for environmentally friendly driving, promoting safety and efficiency on the road as outlined in German traffic regulations.
