Awesome car, in the mag tests beat the z06 by a wide margin on road courses. I think some of the gap could be made up by the z06 if it were also running on pilot cup sports. I hear forum member Woosh has taken the plunge and is taking delivery of an ACR soon!

It's cool to see all these relatively cheap performance cars from everyday manufacturers like Dodge, Chevy and Nissan kick Porsche and exotic supercars' collective asses!

This makes the ZR1 time even more amazing. The ACR is not exactly the "model" daily driver

Is that the rev limiter he keeps banging? Every time I hear that sound I see the shifter shake. I counted two missed shifts, one time getting a little squirrely and that pulsing sound...and still a 7.22!

Could the ACR make it into the 7.1?'s That is one very fast car, but I must say the ZR1 looked alot less "on the edge".

Simply amazing... That car is a "must own" for sure... Unlike that Nissan.

I'm not sure what's up with the rattle in shifter though. Obviously with all of that torque you would have some movement, but the severe rattle? The car definitely looks like a handfull, very impressive indeed! The guys over at the Viper Club Forums are loving life...for the time being.

That's actually slower than I would have expected, that car should be in the teens on R-comps.


Edit: after reading the story, I now see why. Half a day to kill what took GM a few weeks, and Nissan well over a year to accomplish. Pretty astounding.

I'd surely enjoy the suffering of it till my license was gone!

I guess the Viper fanboys can now claim the track was wet in two spots (ring a bell???) so the ACR should be able to shave 8 seconds by that alone and run 7:13 or so.

Noticed the same thing about the missed shifts into third. I also lost count of the number of times I heard the limiter, even on upshifts.

And, he didn't shift out of 4th gear on the straight, bouncing off the limiter the whole time. I thought the ACR was a 6 speed...I'm surprised that 5th would be too tall for that straight on the 'Ring though...

Still mighty impressive!

Thanks for the informative article....The ACR is a "Street Legal Race Car"!!!....Adjustable front splitter, Adjustable rear wing, Adjustable shocks, MPS Cups, many carbon fiber components, "HCP" to further save weight....they paid close attention to the details that count to make the car fast around a track. I'd feel very proud to own that beast!
