That was a handful! 
He did one major thing wrong though, he was not wearing a HANS device. Never leave home with out it, at those speeds anything can happen.

Jeez, what a handful! I love my Corvette, thank you. What sawing of the wheel was necessary, and a couple 1/2 turn correction for torque steer! Wow! Yes, on the Hans device!

Awesome video. I would not be so quick to call the Viper ACR a "handfull". I watched this, then the 7:19 yellow ZR1 lap, then the ACR again. The Corvette driver had at least 4 very big lifts on corner exit, including at 177mph or so under The Bridge. Jeez!!!!! The Viper driver never lifted on a corner exit followed by a straignt. Bushing compliance, tire sidewall stiffness and especially driver style make a big difference on how much wheel movement is used. I have driven with many drivers who produce a lot of wheel movement that is not felt in the car. Other drivers are more "economical" with the steering and go as fast. Also, all the comparos between the ACR and the Vette I have read claim the ACR is world's more stable on the racetrack. It is afterall set up solely for the track whereas the ZR1 is "also designed to be comfortable on the street" (a quote from the ZR1 Nurburgring video).

As with any 600+ hp car, the Viper can be a handful, but with its aero, the ACR is amazingly well planted. Its pretty cool that you can buy a car from the factory and it be that fast.
It would be nice if GM would make a track version of the vette, I bet that would sell pretty well also.

The thing I can appreciate about manufacturing the ACR is this. I picture a bunch of suits sitting around a conference table and someone says,"With the suspension we're going to create a somewhat harsh riding car and with the aero package we're going to reduce gas mileage, acceleration and top speed and with the limited number of cars we will sell there is hardly a business case to support this vehicle. The only thing it will be good for is going around a road course quickly."
Of course then someone else chimes in and says,"OK, let's build it".

I think the ACR-X did the ring in 7.03.XX or something like that.

Even the record-setting effort was done on the proverbial paper napkin, and the person who started it all wasn't even a Dodge employee (Ben Keating co-owns Tomball Dodge in Texas).
The SRT group is a group a hard-core "car guys." Look I started my car life as a GM guy, and never likes Mopars. But these guys are really cool. You'd all like them, trust me.

Same thing happened to me... The SRT guys are tops! I've really liked many things Ralph has done.. They are a very passionate and enthusiastic group of car guys!

No, its the regular ACR. The ACRx would have been quite a bit faster with its factory Michelin Slicks.
As with any 600+ hp car, the Viper can be a handful, but with its aero, the ACR is amazingly well planted. Its pretty cool that you can buy a car from the factory and it be that fast.

With regard to a production-based "track-ready" C6 - what happened to the Z06X and why didn't GM have a go at the ring with it?

Reason I asked the car in the video was an ACR-X, it had a "radio delete" panel and wondered if it may have the X's 640 HP and suspension. At any rate, the ACR is a great car and I enjoy running with the guys that bring them to the local tracks.
