Volkswagen showed off its "Thunderbunny" concept at the SEMA show last November, tempting crowds of hatchies with promises of post-R32 hareiness (ouch). Of course, now we know V-dub is introducing a new R32 in the US this year. So what of the bunny? According to VW blog UK MkIVs the Golf RS above was on display at a VW corporate event. Insiders say the RS will see a limited production run of 500 to 900, with a debut expected for the Frankfurt or Essen shows later this year, ahead of a market launch in mid-'08. As for what may be under the hood. Could this be the "R36" everyone's been talking about? After all, are those not Passat R36 wheels?
