What's the real application here? It surely can't be automotive, the amount of time spent at full load is minuscule at least in cars. My old Model S has a full load output of 250 kW but the typical load is less than 30 kW. Lower power cars spend a bit more time at a higher fraction of full load but still typically far less than 50%.

Of course efficiency and cooling are important but EV drives are already quite efficient and rarely operate at full load so the improvement in practice will be small.

Or is the mention of automotive use relevant only because Porsche is involved in testing?
