@Avnyc11, I saw this and a similar Quad in Brescia at the start of the Mille Miglia. MacGeek said that they were not stock, but Swedish tuner cars.
As is often the case, Andy, you're confused. As a result, your post is misrepresenting my words.
What happened is that you saw 3 different cars: the Giulia and Stelvio Quadrifoglio Alfa Romeo Racing, made by Alfa Romeo, and then you saw the Novidem Stelvio Quadrifoglio R 575, made by a Swiss (not Swedish) tuner.
You then proceeded to mix them up, conflating all of them into one, fooled by the similar livery of the tuner car and by how they were shadowing the genuine Racing versions, and eventually managed to convince yourself that Alfa Romeo made a 575hp Stelvio, which it did not.
That is what I told you then, and what I'm repeating you once again today.
Go reread the original topic:

Please pay more attention in the future.
