Compare specifications
A check mark shows the better value in a row. Range and efficiency check marks compare only values from the same test cycle. Prices are each market's own list prices, compared within that market; some include tax and some do not, and no price is marked better when the tax treatment differs. Energy cost is what the energy for 100 km (100 mi where the market uses miles) costs at the market's latest published national energy price, in its own currency, with the price's source and date.
