ePrimacy is only suitable for econobox EV no more than about 200hp, 250-300Nm.

More powerful than that, it struggles with insufficient grip to put power down.

Very poor reviews from China where latest Volvo also putting ePrimacy even on some of their PHEV. Tyres slip even with 80-120km/h dynamic pull.

It is very subtle, but 9 out of 10 medias mentioned the car should ride better with more capable tyres is a pretty compelling indicator.
