Q&A

Are the MPG figures provided by car manufacturers accurate?

MPG figures provided by car manufacturers are based on specific tests but may not reflect real-world driving conditions.

What is the difference between NEDC and WLTP tests?

NEDC tests were used in the past but were not accurate, while WLTP tests aim to provide more realistic fuel efficiency figures.

Can I expect to achieve the same MPG as stated in the brochure?

The MPG figures stated in the brochure are based on ideal conditions and may vary depending on driving habits, road conditions, and other factors.

Why do MPG figures differ for different types of driving?

MPG figures can vary based on factors such as speed, acceleration, use of air conditioning, and traffic conditions.

How can I improve my car's fuel efficiency?

You can improve your car's fuel efficiency by driving smoothly, avoiding excessive idling, maintaining proper tire pressure, and reducing unnecessary weight in the vehicle.
