To get the best out of something like V Power, a car needs to be mapped to make the most of it. ECU does have some ability to learn different fuels but as they are generic and have to work under huge variation of fuel quality and external factors they aren't able to fully utilise better fuel.
If you can get a custom map and stick to V Power you'd get a nice performance increase, even without any hardware changes. I expect a Cupra would go very nicely mapped to it. My Impreza does.
