How it works
Your manufacturer-rated efficiency and real-world efficiency can differ quite a bit depending on city driving, highways, and AC use. Fill in section 1 to get your car's real efficiency — it automatically feeds into the trip prediction below.
FAQ
Q. How do I measure real efficiency most accurately?
A. The 'full-to-full' method — fill up, reset your trip meter, then check how many liters it takes to fill up again — is the most accurate.
Q. Why does efficiency drop in winter?
A. Longer engine warm-up time plus lower tire pressure and battery efficiency all compound together.
