I see, I had to look it up. Yes, a car with a "Sports" suspension tune will always feel a bit harsh. I am surprised at this marketing ploy, it does not fit the character of the car at all. The PHEV has always been known for the smoothness of its ride, for asphalt burning on the circuit it would be my last choice.
Trying to make a two ton SUV behave like a Porsche is like trying to teach a Cow the Viennese Waltz.
Maybe you could fit different shock absorbers?
