During Ralph Gilles recent visit to Boca Raton FL to meet with Viper owners while on his way to Jay Lenos Garage with the new 2013 SRT Viper,  he mentioned that the Viper Roadster would be held back by two years, mainly because orders for the coupe need to be filled first and that the inevitable ACR version would be bound by the same production constraints.

In addition to those constraints, the ACR would also have to go through homologation for racing purposes, likely dictating which route the newly re-trademarked ACR-X Viper will go first, so they can then make an ACR street version from it.  Ralph also touched on the recent woes between the Viper and Corvette ZR1 that were published by Motor Trend magazine, stating that they had a ZR1 themselves for over two years and while close in some areas (launching, acceleration), the Viper beats it, and will beat it – on any track.  They are going to prove this to Motor Trend by taking three cars back to them, along with their own driver, to race against Randy Pobst in what we assume will be the ZR1 to prove once and for all, which car is really faster around the track.

He said the ZR1 has easier reachable limits, but the Vipers limits are higher, they just take a little talent to achieve and that is what makes a Viper a Viper.  They are proud of that, and its not going to change.  He closed off his chat by saying they would be taking the car to the Nurburgring in the spring, and noted that their old record had still not been beat.
