Last year, we reported that the sweet Audi RS3 is more or less guaranteed for the U.S., likely in sedan form, as Audi?s U.S. CEO Scott Keogh considers it a ?great halo car? for the line. And now, this picture, leaked via Instagram and posted on Quattroworld.com, depicts the RS3 sedan model during a video shown at an Audi U.S. employee summit.
Before we go on, though, there has been some debate among Internet commenters about it possibly being the RS4, a car equally shrouded in mystery at this point. Here?s how we know it?s an RS3: the lower swage line, a.k.a. ?light catcher,? in the lower doors is strictly a positive surface both on today?s A3/S3 models and on this car, while the same element on the A4/S4 is a negative surface above a positive surface. Granted, the headlamps on this car look like those on the new A4, but the A3 is due for a facelift next year, and the same reports allege that the RS3 will don the A3’s new face, which will adopt the A4-style headlamp design. The RS4 is also likely to feature prominent fender flares, which this car does not. Oh yeah, and when we reached out to Audi spokeswoman Amelia Fine-Morrison, she confirmed it is indeed the upcoming RS3. So there.
