To me, these look like 2.0i TDI alloys. When these first came out as an option on the S3, the saleswoman took it upon herself to tick the option box, even though I said I wanted the standard wheels. Luckily I spotted it on the order confirmation, and told her very politely but firmly, to get them off my F**king car. If these had been on my car on collection day, I would have rejected.
They have grown on me over the years, as I've seen a few S3's with them on. But don't look special enough to be on an S3. Personal opinion of course.
No alloy wheel design looks special on a S3
