Common questions

Why is UK MPG higher than US MPG for the same car?

The UK gallon is larger than the US gallon, so the same fuel use spread over the same distance produces a bigger MPG figure.

Is a lower L/100km better?

Yes, L/100km measures fuel used per distance, so a smaller number means the car is more efficient.
