Looks a cracker! Wheels are epic.
Think they've gone A1 quattro so as not to tarnish/replace the S1 name. It has the current corporate RS styley front bumper, so doubt you'll see a S or RS version specifically.
I think it's a positive step to see the 2011 Worthersee concept almost exactly replicated bar the twin side exit exhaust and 2.5l in it. Can you imagine a 2.5 in this?! Yikes.
Fingers crossed the 2012 Worthersee is the next gen 3dr RS3 concept eh?
With spy pics of next gen A3 looking like a bigger version of the A1, could be good things ahead for next S and possibly RS3.
