It makes no sense. A/C is an option in the ACR, but for a non-road legal car. . .

Knowing Chrysler though, it has no A/C but they threw in an a/c hvac control because it's cheaper than producing a non A/C version.

Crazy that the ACR is holding an 88.5 mph AVERAGE speed

Just some perspective:

We ran 1.31s flat at Laguna on a race weekend in 2008 with F430 Challenge cars and gentleman drivers. Profesional drivers are not eligeable to compete. Our cars are making 130 LESS hp than the ACR-X.

The ACR-X times were produced with an admitted professional, currently competing driver behind the wheel. I'm sure we are all aware that a professional driver vs an amateur = shaving seconds per lap.

You can not compare a GT3 or RS to this Viper ACR-X. The GT3 and RS are road cars fully equiped on street tires. The ACR-X is a production based race car on slicks.

If you wated to compare the ACR-X to a comparable Porsche, look here:

### 997 gt3 r ###


Final note: I am NOT dissing the Viper. I'm a big fan of the car, particularly the ACR and now the X.

The X was on MPSC's as far as I know, not slicks.

The ACR was on MPSCs the "X" was on slicks.

The time and distance I posted was from the standard ACR road car compared to a GT3 or RS.

From what I can gather this acr-x was still on standard acr mxpx tires. Reason being this car is being designed around a viper club spec class and they haven't chosen a class tire yet. The production cars will come with those tires

Look like Hoosier slicks to me. They don't even look like Hoosiers "DOT's", But rather their full race slicks. They are not MPSCs.
