This page exists because e-auto once published three different cost-per-kilometer pairs in three different places on the same site. They weren't calculation errors: they were two different quantities sharing one name. Here they're kept apart, with their formula and source.
Energy cost is what it costs to move the vehicle: fuel or electricity, nothing else. It doesn't depend on annual mileage. Total operating cost adds maintenance, tires, insurance and circulation permit — and it does depend on mileage, because those fixed costs get spread over more or fewer kilometers. Conflating the two names is what produced the contradictory versions.
| Variable | Value | Source |
|---|---|---|
| Diesel price | $1388/L | Santiago metro pump average, 505 stations, National Energy Commission, Aug 1 2026 |
| Reference diesel performance | 10.1 km/L | Median of 3CV registry, MC3D diesel vans, n=453, homologated since 2023 |
| Diesel cost | $137/km | 1388 ÷ 10.1 |
| GECKO EV48 certified performance | 6.2 km/kWh | 3CV, certificate C.H. 6940 |
| AC/DC charging losses | 10% | Billed at the meter, never reaches the battery |
| Commercial electricity tariff | $130/kWh | Market reference |
| EV48 cost, commercial tariff | $23.1/km | (130 ÷ 6.2) × 1.10 |
| Free-market client tariff | $85/kWh | Negotiated, not every company has it |
| EV48 cost, free-market tariff | $15.1/km | (85 ÷ 6.2) × 1.10 |
At commercial tariff, the EV48 costs 6.0 times less in energy than the reference diesel. At free-market client tariff, 9.1 times less. The first figure is always published as the conservative one.
Adds energy to maintenance, tires, insurance and circulation permit (plus AdBlue for diesel). Since fixed costs get spread over the kilometers driven, the result changes with how much the vehicle is used — that's why it's never published without stating the mileage.
| Annual mileage | Diesel | GECKO EV48 |
|---|---|---|
| 30,000 km/year | $222/km | $77/km |
| 40,000 km/year | $201/km | $63/km |
