The EQC 400 was the first electric Mercedes sold in Australia, and the earliest cars are now seven years old. It carried a large, heavy, thirsty pack, and Mercedes' 8-year battery plan applies to cars registered after 1 March 2020 — so a 2019 example needs its paperwork read carefully before you assume any cover.
The pack
| Variant | Years | Usable kWh | Claimed range (WLTP) | Real-world consumption |
|---|---|---|---|---|
| EQC 400 4MATIC | 2019–2022 | 80.0 (85.0 gross) | 411 km | 21.6 kWh/100km — modelled |
An 80 kWh pack for 411 km of claimed range tells you what kind of car this is: a 2.4-tonne SUV with two motors and the aerodynamics of a conventional Mercedes. At a modelled 21.6 kWh/100 km it is roughly 370 km of real driving when new, and an older pack that has lost a tenth of its capacity is a 330 km car.
Why the EQC deserves a measurement more than most
Three reasons. It is among the oldest EVs on the used market, so calendar ageing has had time to work. It has one of the largest packs, so a replacement — for which Mercedes publishes no price — would be correspondingly expensive. And Mercedes publishes no capacity percentage, so there is no number to hold a claim against.
That combination means a used EQC is where an independent, dated measurement earns its keep. The car has depreciated hard, which makes it tempting; the battery is the difference between a bargain and a liability.
The warranty date, plainly
Mercedes' EQ Owner Protection Plan gives 8 years or 160,000 km on the high-voltage battery for vehicles registered after 1 March 2020, and unexpired cover may be transferred. An EQC first registered in late 2019 falls before that date. What cover, if any, such a car has should be confirmed with Mercedes-Benz Australia in writing rather than inferred. Full terms: Mercedes-Benz battery warranty in Australia.
