That's a great question! It's kind of hard to give you a super scientific answer because we'd need to know the prices of all kinds of fuel in every country, plus how much gas different cars use. But I can tell you about my old diesel car. It 'drinks' about 6.3 liters of diesel every 100 kilometers.

The chart shows how much it costs to drive an electric car for 100 km. Diesel in Portugal is €1.54 a liter this week. 1.54 x 6.3 = 9.64 euros

Portugal: 9.64€ (diesel) vs 3.2€ (ev) -> 100 km (62 miles)
