They said anything but metric. The SI unit for power is the Watt, sure, but there are other metric units that are not SI units. One of these is the metric horsepower. 1 metric horsepower is defined as the amount of power required to raise 75kg of mass 1 meter in 1 second against Earth’s gravity. I used pferdestärke because automakers use the “PS” abbreviation in my experience.
This unit exists as an attempt to have a value comparable to historic mechanical horsepower measurements but defined with metric terms.
Obviously Watts are the preferred unit for most things, but the automotive world still likes horsepower. So, metric horsepower.

Colloquially “metric” means the SI-system though. It’s not all prescriptively correct terms. Hell, even the name isn’t, as the French and English couldn’t
So I’m not goanna say your wrong per se. But you’re not exactly right either

In what way am I not right? We’re talking about an electric motor for automobiles, and I gave a metric unit that automakers use. What’s more, I also gave it in kW! 🤣

Automakers using a unit doesn’t make it metric.

That sounds very dependent on the language. I’ve never read/heard “PS” before. Let’s just use kW ffs.
