I have not merely told you so, I couldn't shut up about it for years.
It's an EV with sodium ion batteries. The capacity of 25 kWh is not huge, but the regular capacity of this model with lithium is either 20 kWh or 31 kWh.
But this one is faster charging and better in winter.

The pack energy density of 120 Wh/kg (cells have 140Wh/kg) is just a sliver below the 2020 Tesla Model 3 LFP pack, which had 125 Wh/kg.
If you build the same 54 kWh pack with sodium, it would weigh 450kg, just 18 kg more than the LFP pack. But it can charge to 80% in 15 minutes.
