I assumed they missed an 'h' there.

People seem to get easily confused by the W/Wh and A/Ah thing. A rental car I've took recently showed power usage in 'kWh per hour'. Bleh.

kWh/h is a proper unit for average energy consumption over time, if a bit weird.

It's something that's used, but I'd make the case it was never proper. The time component is right there!

If you think of watt-hour as "joule times 3600" then it makes sense

The author missed an 'h', its 12.5 kWh / 100 km

It uses 12.5 kW per 100km travelled. But should be of course kWh.

Pretty sure it should be kWh / 100 km

should probably be 12.5 kWh / 100 km
