The filter here is deliberately the observed figure, not the official one. Plenty of cars claim 400 km and deliver 320. This table only contains cars that actually cover 400 km in independent mixed-conditions testing, ranked by what they cost.
Ranked from the 12 cars in our database that have a sourced figure for this. A car with no published figure is left out rather than ranked as a zero. Figures are US units; every model page carries the metric equivalent and the source.Figures are metric; every model page carries the imperial equivalent and the source.
Why the prices are in euros only
Because a car’s US and European prices are not the same price in two currencies — they are different market prices, set by different tax regimes, incentives and competition. Converting one into the other produces a number that describes neither market, so this site publishes them separately and this ranking uses the European figure it has for the most cars.
Each car’s own page carries the UK and US figures where they exist, with the source and the date each was read. Local incentives are not included anywhere: they change constantly and depend on where you live, your income and sometimes how you finance the car.
Purchase price is the smaller half of the question
Two cars a thousand euros apart at list can differ by far more than that over five years, because efficiency compounds. A car at 173 Wh/km against one at 216 Wh/km uses about 20 percent less electricity for every kilometre you drive — which at 15,000 km a year is roughly 645 kWh, annually, for as long as you own it.
The running cost calculator puts your own tariff and mileage against a petrol car and shows the crossover. Every assumption in it is visible and editable — there are no hidden multipliers.
What is missing from this table
Any car we have no European price for, and any car that does not clear 400 km observed. That excludes some genuinely good cheap electric cars — they are simply shorter-range, and this particular ranking asks one question. The count under the table says how many cars it drew from.
Frequently asked questions
Why 400 km and not 500?
Because 400 km of real range covers the longest journey most drivers make regularly with a margin, and raising the bar to 500 would leave a table of premium cars — which answers a different question. The range ranking has no price filter if that is what you want.
Do these prices include delivery and options?
They are list prices for the specification named, excluding delivery and options. A real invoice will be higher, and the gap varies by market and by dealer.
Is the cheapest car here the cheapest to own?
Not necessarily. Check its efficiency in the second column: a cheaper car that uses 20 percent more electricity can cost more across five years than the one above it.
