What this tool does
The saving depends as much on how far you drive as on the difference in consumption, which is why a thirsty car matters little to someone doing 5000 km a year. Compare the annual saving against the price difference before deciding anything.
Formula
savings = (c₁ − c₂) ÷ 100 × km × price
