In addition to that new record for street legal production cars set by the Viper SRT10 ACR, the Dodge Viper ACR-X reportedly hit the track as well, ripping off an awesome lap time of 7:03 according to the folks at the Viper Club of America. That time puts the Viper ACR-X third overall among non-street legal models, trailing only the Pagani Zonda R (6:47.5) and the Ferrari 599XX (6:58.16).
