What the evidence shows
A battery car can have lower five-year costs when it is bought near price parity and charged cheaply, but there is no Europe-wide winner. ADAC’s April 2026 German comparison changes with the electricity tariff; a TCS Swiss field test found public-only charging cost more per 100 km than its petrol benchmark.
THE VEHICLES BEHIND THE NUMBERS
Older vehicles or current generations?
ADAC compares new-for-sale powertrain versions, not older and modern cohorts of the same model. Its €37,990 Astra Electric Edition row does not uniquely identify a version: ADAC lists a 12/2024–01/2026 Edition and a 03/2026 facelift at that price, both 2023+; their battery sizes differ. TCS does not name its test vehicle, and GDV reports claim years, not model years. A direct pre-2023 versus 2023+ cost comparison is therefore not valid.
We separate vehicles from before 2023 and 2023 onward. A report’s publication date does not establish a vehicle’s model year or a battery’s manufacturing date.

Vehicles / sample
ADAC's Astra Electric Edition cost row is compared with the Astra 1.2 DI Turbo Hybrid Edition and Astra 1.5 Diesel Edition. The €37,990 EV list price matches more than one catalog version, so the exact variant used in the cost row cannot be determined.
Vehicle years
ADAC's cost model uses April 2026 prices, not model-year labels. Catalog candidates at €37,990 include Astra Electric Edition (12/2024–01/2026) and Astra Electric Edition facelift (from 03/2026); both are 2023+ production versions, but the row does not identify which one.
Battery chemistry
ADAC lists Nickel-Cobalt-Manganese (NCM) for both price-matching versions; the cost row does not identify which battery version it models.
Battery capacity
Conditional on the version: 54.0 kWh gross / 51.0 net for the 12/2024–01/2026 Edition; 58.0 gross / 55.0 net for the Edition facelift from 03/2026. The €37,990 row cannot distinguish them.
Battery manufacture
Not reported for either version.
Observation period
ADAC German new-car price and cost database as of April 2026; modeled five years and 15,000 km/year.
“Not reported” means the source does not disclose it. Model year, first registration, vehicle assembly and battery manufacture are different dates. Unmatched studies cannot establish how much newer batteries improved.
MANUFACTURERS IN THIS EVIDENCE
Which brands do these results describe?
ADAC reports a named Opel Astra Electric and petrol/diesel Astra cost model at several German charging prices. This allows a trim-specific same-nameplate scenario comparison, not a Europe-wide or make-average result; other cited studies do not identify their models.

The word “always” overstates what the cost evidence can establish. A fair comparison has to count purchase price, depreciation, energy, maintenance, insurance and taxes over the same ownership period. Those costs depend on the specific country, vehicle pair, annual distance and charging access. ADAC’s April 2026 calculation is useful because it makes those assumptions visible, but it describes new cars and German prices rather than a European average. Its study compares versions with broadly similar equipment and power, and reports cost per kilometre across four electricity-price scenarios. [1]
For a concrete pair, ADAC lists the Opel Astra Electric Edition at €37,990, the Astra 1.2 DI Turbo Hybrid 48V Edition at €32,990 and the Astra 1.5 diesel at €34,640. The electric version therefore starts €5,000 above the mild-hybrid petrol and €3,350 above the diesel. These are April 2026 German list prices including 19% VAT, not transaction prices after dealer discounts. [1]
Charging price changes the German five-year comparison
ADAC assumes five years of ownership and 15,000 km of driving per year. For the Astra Electric, its all-in estimate is 57.7 cents/km with electricity at €0.18/kWh, 60.2 cents at €0.35/kWh, 61.9 cents at €0.45/kWh and 64.0 cents at €0.60/kWh. The two combustion comparators are estimated at 61.9 cents/km for the petrol mild-hybrid and 66.3 for diesel. Thus the EV is cheaper than both at the lowest tariff, slightly cheaper than petrol at the standard home-tariff case, ties the petrol comparator at 45 cents/kWh, and is more expensive than petrol in the public-only price case. [1][2]
The 18-cent scenario represents charging through the owner’s solar system; 35 cents is a normal home tariff; 45 cents represents mainly home charging with some public charging; and 60 cents assumes public charging only. At 75,000 km, the difference between 57.7 and 61.9 cents/km corresponds to about €3,150 in modeled costs. This is a calculation from ADAC’s per-kilometre estimates, not a guaranteed saving for a particular buyer. [1]
A Swiss field test shows why home access matters
The TCS’s 2025 test followed a mid-size electric SUV for five months, recording 102 charging events over 15,567 km in Switzerland, Italy and France. Most sessions were DC fast charging. The average paid price was CHF 0.74/kWh, and the tested public-charging profile cost CHF 15.80 per 100 km. TCS compared that with CHF 10.32/100 km for a petrol car using 95-octane fuel. Its calculation for mostly private charging was CHF 7.91/100 km, using the Swiss home-electricity reference of CHF 0.29/kWh. That makes access to a private or workplace charger a major condition of the energy-cost result. [4]
This TCS test does not add purchase, insurance, maintenance or resale costs, so it cannot settle lifetime ownership cost. It is also one driver’s use of one vehicle, not a national survey. The value is narrower: public-only charging can make electric energy more expensive than petrol on a per-distance basis, while home charging in the same comparison costs less.
Collision claims add a separate insurance variable
ADAC's TCO model includes estimated insurance cost, but a separate claims analysis shows why premiums and repair costs should not be inferred from one another. For Germany, GDV reported that during 2021–2023 the average comprehensive-insurance claim for an EV was 15–20% higher than for a comparable combustion car, while the claim frequency was 10–15% lower. In the prior 2020–2022 window, the severity difference was 20–25% and claim frequency 15–20% lower, so both gaps narrowed. This is German insurance-claims evidence, not an individual premium quotation or a European average. [5]
Higher average cost per claim can coexist with fewer claims, and neither figure alone tells a household what its annual premium will be. The ADAC model's insurance line, local insurer pricing and a buyer's own policy terms remain relevant to a country-specific comparison.
Apply the numbers to the country and car you will actually buy
ADAC’s cost model includes expected depreciation, energy, servicing and common repairs, tyre replacement, insurance and German vehicle tax. Its standard method uses manufacturer WLTP consumption and estimates resale value from German used-car price data; it does not include loan interest. German tax exemptions for electric cars are included, but the article excludes the 2026 purchase grant because eligibility and amount vary by household. [1][3] These assumptions can materially affect the comparison: a grant may close the upfront-price gap, while a different national tax regime or expensive public charging may move it the other way.
The defensible conclusion is conditional. Electric cars can cost less over a defined ownership period, especially when the purchase premium is small, annual mileage is substantial and most charging is affordable. They do not automatically beat equivalent combustion cars in every European market or for every driver. Buyers should recalculate using local tax and incentive rules, real purchase offers, expected resale value, insurance quotations, driving distance and their actual mix of home, workplace and public charging.

This is a representative claim, not a quotation attributed to a particular person or publisher.
What this does—and doesn’t—tell us
ADAC’s costs are a Germany-specific model, not a European average: vehicle prices, fuel and electricity prices, taxes, insurance, incentives and resale values vary by country and household.
The ADAC calculation excludes individually determined 2026 purchase subsidies and financing interest, although its April 2026 method includes German EV tax exemptions. List prices include German VAT; actual discounts and personal insurance rates can change the result.
The TCS figure is an energy-cost field test of one vehicle and one driver, with routes in Switzerland, Italy and France. It is not a matched-model, lifetime ownership comparison or a representative sample of all Swiss drivers.
GDV's 2021–2023 German comprehensive-insurance claim data describe claim frequency and average claim severity, not insurance premiums for an individual driver, scheduled maintenance or a Europe-wide result.
All listed companies are original equipment manufacturers (OEMs). EV-focused describes portfolio emphasis, not BEV-only sales; multi-powertrain describes a broader lineup. These are broad context labels, not quality scores or chart results. Counts are plotted observations; a chart can show multiple test conditions or cost components for the same model.

German-market all-in cost estimates at 15,000 km/year, with €1.92/litre for petrol and diesel. April 2026 list prices: €37,990 for Astra Electric Edition, €32,990 for Astra 1.2 DI Turbo Hybrid 48V Edition and €34,640 for Astra 1.5 Diesel Edition. Electricity scenarios are €0.18/0.35/0.45/0.60 per kWh. Includes modeled depreciation, service and repairs, tires, insurance, tax and energy; no individually calculated purchase grant or financing interest. German result only.
Compare all-in costs for the exact country, models and charging access. The EV can win with cheap charging and a modest price gap; the result can reverse when it costs more to buy or depends on expensive public charging.
