What does a trip cost?

Fuel cost–

Prices start at an example. Change them to what you pay. Economy starts at the car’s official combined figure, or a typical real-world one for cars without an official result.

Real-world economy

Official figures come from a lab test. On the road, motorway speeds, short trips, traffic and cold weather usually use more. Motora records each drive in your A8 L 4.2 TDI quattro and works out what it really used from how you drove, priced with pump prices near you. How the drive tracker works.
