Volkswagen e-Golf vs Toyota Prius: charging and fuel costs over 10,000 km
A Spanish real-world comparison puts the e-Golf at €586 on public AC charging and €799 on DC, versus €569 on LPG and €726 on petrol for the Prius.
€586 or €799 for the same 10,000 km — that is how much the charging method can change an electric car’s running costs. Spanish motoring writer Javier Costas compared his real-world Volkswagen e-Golf experience with a Toyota Prius on the same routes, producing a result that exposes the weak point in any claim about “cheap electric driving”: consumption matters, but so does the price of every kWh.
In the Spanish test, the e-Golf averaged 14.26 kWh/100 km. With public AC charging at €0.41/kWh, 10,000 km cost about €586. Fast DC charging at €0.56/kWh raised the bill to €799.
For the Toyota Prius, the author recorded 6.37 litres of LPG per 100 km and 5.04 litres of petrol. At the fuel prices used in his comparison, 10,000 km cost €569 on LPG and €726 on petrol. That means the e-Golf on public AC charging was almost level with the LPG Prius, while fast DC charging made it roughly 40% more expensive. AC charging was still about 19% cheaper than running the Prius on petrol.
Those figures also give a useful break-even point. At this consumption, the e-Golf matches the LPG Prius at roughly €0.40/kWh. Against the petrol Prius, the threshold is about €0.51/kWh. These are not universal tariffs for every country, but a simple way to test your own case: multiply EV consumption by the actual charging price, and combustion-car consumption by the fuel price.
That is why a cost calculation based on home charging cannot automatically be applied to a driver who relies mainly on public fast chargers. A home socket or a workplace wallbox is often not a minor bonus, but one of the key conditions for an EV’s financial advantage.
Maintenance is simpler in several respects. According to the U.S. Department of Energy’s Alternative Fuels Data Center, battery-electric cars have fewer regularly serviced components and fluids, while regenerative braking reduces brake wear. The battery should not be treated as “permanent”, however. A Geotab study covering more than 22,700 EVs found average capacity loss of about 2.3% per year, with charging power and frequency, climate and operating conditions among the important factors.
So the useful question when choosing an EV is not simply whether an electric car is cheaper or more expensive than a petrol car. It is where the vehicle will be charged most of the time. That single factor can change the final cost more than the difference between the powertrains themselves.
