Bit confused..

this article.. says Jim mero ran ~2:39.77 in c7z @ VIR, acr Viper time was 2:40.02

when Randy Pobst ran '15 z06 @ Laguna Seca 1:33.05, gen V Viper ACR ran 1:30.46

Is it because the c7z ran @ VIR has updated suspension tuning? Just confused why the c7z edged out the acr @ VIR and lost @ Laguna Seca

Yes, I know they are different tracks, different weather, different drivers, etc.. still curious why this was the result

No, they mention in the video the car they had for the test vs viper acr @ Laguna seca, it was running great

They said when they ha a c7z for best drivers car competition, it wasn't making any boost. So I think you are thinking of that episode

I believe they ran both the C7Z and the GT3RS early in the day when there wasn't as much grip (hence them crashing the GT3RS).

Poor-sha

Was that the test where Randy kept complaining about how loose the C7Z was? As I recall they later determined that the rear caster wasn't set properly which is what prompted all of us to start checking it.

Yes, if it's the test I'm thinking about, they later discovered that the alignment was off.

i believe that was the GTR vs C7z @ Willow springs

Watch the video he linked. This was the loose Vette with alignment issue. Randy even says the prior Best Driver's car they drove was the one that had the power issues.

It's not obvious to me if this yellow c7z is the same z06 they used to compare to the GTR @ Willow springs. I KNOW for a fact the one they used for the test vs the GTR had rear alignment issues.. here is an article about that

Yeah not sure. It's clear that GM had given some cars with poor setup or mechanical issues and over time, GM has figured out how to ideally setup the car. The changes in suspension tuning seem profound though as the laptimes are dramatically improved.

The Z06 went from a bad set-up to one now that keeps fine tuning going faster and
The ACR is out of production.

Z07 is TA competitor


ZR1 is ACR competitor (even same price range)


To me the ACR true lap time is 1:31.58 which happened on a nice clear day and it seems to be an ACR that Dodge didn't specifically prep for a best lap time test. Randy tested the ACR three times. Each time he went slower than the prior test.


The ACR is faster than the Z07 as it should be being more track focused. I hope Dodge will consider bringing it back to life.

The V10 8.4L Viper is done and it ain't coming back.
Perhaps in the future, Dodge will resurrect the name and put it on a Sportscar, but it won't be a car resembling previous gens...that much is certain.
