The talk is spurred by leaked patent drawings dug up by Autoblog Spanish and relayed into English by Autoblog. The images depict exactly what you'd expect: a 2012 RS5 with no roof. It's expected to get the same power-electric soft top as the standard A5/S5 Cabrios, and will likely get the same power and suspension upgrades as the standard RS5.
The convertible will probably weigh more than the coupe, however, and might get a bit softer suspension tune to suit its more laid-back open-top style. We'll be on top of the news as it develops, so stay tuned.
