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 A3 Sportback 35 TFSI S line and works out what it really used from how you drove, priced with pump prices near you. How the drive tracker works.

Build it in 3D

Put your A3 Sportback 35 TFSI S line in your Motora garage, paint it, fit wheels and a body kit, set the stance and park it next to your friends’ cars. See the 3D garage.
