the new viper acr

[bananapeel42]

It is definitely fast, but the tires disqualify it from holding the "record" time. In fairness, the ZR-1 would post at least as quick of a time with similiar tires.

I doubt it. The Vette's got power but without the downforce additions it wouldn't be able to turn like the Viper will.

That driver was doing my nut, why didn't he go above 4th on the last straight?

That suspension may be able to make up some of the difference, it's some pretty advanced stuff.

It's all about the tires.

r-comps on the ACR.

Yeah, to recap : this thing is wicked fast, but almost completely impractical as a DD unless you positively bleed money.

Super downforce/grip tuning + Rcomp tires = probably fuel economy in single-digits along with eating those tires like there's no tomorrow.

Two things. First, the GT-R and ZR-1 "claimed" to use stock tires when running the ring, yet people have claimed that they scrubbed their tires and such, so "stock" is a loose term. No one really knows except the MFR's.

Second, is any Ferrari/Lamborghini/supercar really a "practical" daily driver? You're probably right, it more than likely gets in the single digits for fuel mileage, just like ever Ferrari and Lamborghini out there. And at "normal" driving speeds the downforce won't eat up the tires as quickly I'd imagine.

Hmm, I think the accessibility/practicality of exotics/race cars vary widely from what I've heard. I've sat in a Gallardo, and it was very easy to get in and out of, very comfortable, and visibility was quite good. A *HUGE* contrast to a Countach that I sat in during a Dallas car show in the '80s. Further, general reliability is sometimes an issue, though I doubt that would be the case with a Viper.

Ferrari's are also known to be quite accessible these days, depending on the model. The 599 is supposed to be very much a comfortable GT class, ditto with things like the upcoming California.

Fuel economy also seems to vary pretty widely.

Gallardo : 13mpg combined

Veyron : 10mpg combined

Aston Martin DB9 : 15mpg combined

Audi R8 : 15mpg combined
http://www.fueleconomy.gov/feg/noframes/24167.shtml

Exige S : 23/29!!

2008 Viper : 16mpg combined!! That's pretty damned good really
http://www.fueleconomy.gov/feg/noframes/24752.shtml

And so on. It's really a case-by-case basis. It does look like the extra resistance on the ACR Viper might not even drop it to single-digit levels, which is pretty impressive by any measure of cars of this magnitude. Would be interesting to know for sure. As for the tires, pretty much any soft-compound performance tire will wear much faster than the cheaper harder stuff. This is taken to a new level with Rcomps, they fall apart pretty fast because they grip everything so damned hard.

Seems to go (reasonably) hand in hand with engine displacement.

The Exige S is around 300 hp, while most of the others are alot higher. It'd stand to reason that it would have good economy (although I'm surprised it's THAT good).

From what I watched he was a good driver, the car is just not geared for that kind of a track. The Corvette gears are very lenient when it comes to those corners. I just liked how he was riding the redline and the gearbox was shaking vigorously, talk about good for the car 😛 He also missed a gear in the first 2 minutes of the lap. If the gearing was different for the Viper, I would say sub-7:20 'Ring lap times, which would be sweet.

Not really a victory over any of them.

How do other race cars compare to that time?

It's the same sort of car as a F430 Scuderia. I'm betting it's a lot faster than the Scuderia.

I'd be scared as shiz if I was a passenger in there

I couldn't even imagine. I took a ride in my friends completely stock (besides aftermarket Hawk brake pads) Celica GTS around Waterford Hills Raceway and it was a very white knuckle ride. We kept pace with an Alfa Romero sedan which was a track only car (cage, tires, gutted, engine mods etc.).

My friend has been racing since the '90s so he is a pretty capable driver. The Alfa looked something like this:

[djnsmith7]

Overall, he is a fast driver, seems to be pretty comfortable with the car & knows the track. His shifting habits are very different from mine. I seriously don't see the need to hit the rev limiter so often. But, we all have our individual driving style, so to each their own. Fast car, nonetheless.

 

[RichUK]

Lol, look at the gear lever. :laugh:

 

[Miklebud]

All that, and it still has the HVAC controls from a Chrystler Minivan.

Its the same transmission in both the Viper and the Corvette....I'm not sure about the final drive ratio though....

Ya know, call me petty, I just don't like the way the thing looks/sounds.

Factory - Dodge/Chrysler has a history of putting out ACR models.

Neon ACR
SRT Neon ACR
Viper ACR

Fans dubbed ACR as "American Club Racer"
ACR to Dodge is "competition package"

I love my SRT Neon ACR. Handles really damn well out of the box.

 

[halik]

That looks a lot less sketch than the corvette... the driver of the ZR1 was constantly near-crash.

 

[LordMorpheus]

He didn't bother shifting out of 4th, and he missed his gear at least twich (he probably really didn't like the gearbox, hence the bouncing it off the limiter instead of shifting all the time). Amazing lap, love the noise.

I think you sorta have to be to put in a good lap 😛

Heck, watch the YouTube video of the Radical setting the record, I thought the guy was gonna go flying a few times (although overall he did seem alot more composed).

Once upon a time there was a fox strolling through the woods.
He came upon a grape orchard. There he found a bunch of
beautiful grapes hanging from a high branch.

"Boy those sure would be tasty," he thought to himself.
He backed up and took a running start, and jumped.
He did not get high enough.

He went back to his starting spot and tried again.
He almost got high enough this time, but not quite.

He tried and tried, again and again, but just couldn't get high
enough to grab the grapes.

Finally, he gave up.

As he walked away, he put his nose in the air and said:
"I am sure those grapes are sour."

I don't get the people saying this isn't like a regular car. Why isn't this the same? It's street and track legal. Viper never had the prettiest interior and wasn't the most comfortable ride. A/C in these cars blow pretty much hot air and comes out softly every time you press the gas. But look at cars like Elise and Exige. These have even worse interiors and isn't the most comfortable either. Yet people consider these regular car. So what makes this Viper any different?

Viper doesn't have eurosnob badge appeal.

It's a $80,000+ vehicle. It has the same HVAC knobs/graphics as a 1992 Minivan. Ugly interior. I know it's a "race car", but damn. Do domestic automakers not care about interior aesthetics?
