I have a scorpione, there are a few differences to the full fat Abarth.
Seats are half leather, half suede (microfibre in Abarth speak)
No Brembo brakes
Dash trim, centre console trim and instrument cluster trim is soft touch plastic instead of alcantara
No heated seats or mirrors
Only available in solid black or solid white
I imagine there are a few other bits but those are the main ones AFAIK
