Gen2 currently holds the fastest time around the ring for a production car. That is what I believe and that is what I am sticking to.
Huh? The 2008 ACR (probably) still holds that: 7:22.1
Unless someone held a record run a Gen2 in the last few months...and I missed it !?
To the OP: I was fortunate to play a teensy-tinsey pit-dog role at some of the ORECA championships you cite.....and the champagne showers will never be forgotten. I have a 1996 B/W GTS ... since the day the 1st one was released. As stunning as an XKE.
But my G-4 ACR is the BEST of the dozen+ Vipers I have owned.
And I fully expect the G-5 to supercede the G-4 performace benchmarks...including the 'Ring.
