Click above to view video after the jump

A couple months back, the bone-stock Corvette ZR1 put supercars everywhere on notice when it took on the famed Nurburgring and ran a Nissan GT-R-beating 7:26. The track-ready, fire breathing Viper ACR bested the Corvette's amazing effort by posting an incredible 7:22 lap time. Despite a four second difference in total track time, blogger Andi Baritchi slapped both track videos together (after 30 seconds of annoying scrolling text) to verify that the Viper ACR came out on top. Hit the jump to view the two fastest American-made, street legal, 600+ hp beasts as they tangle in a 'Ring battle for the ages. The video proves what we already knew, but it's still fun to see how two very different, yet very similar vehicles, handle the twists and turns of the Nurburgring. Check out the vid after the jump. Thanks for the tip, Jordan!

      Full VCA video with telemetry of the ACR Nurburgring lap is now online. Possibly a leak; just saw it pop up on youtube as a response to my video.

      absolutely worthless comparison. ZR1 was running PS2 street tires, with 220 treadwear; ACR had PS cups "DOT-legal" tires with 80 treadwear, the kind SCCA uses for GT races.

        no need to get your panties in a bunch, nobody is talking about your strangely insecure sensitivities.

        ACR sounds like a fun car, but the fact that they had to resort to such a cheap trick like using R-comps and still pretending that it's a production car simply betrays the fact that it would otherwise be much slower than ZR1.

        Therefore the worth of comparing ACR to ZR1 is exactly zero.

      Take note that the Dodge Viper ACR is NOT offered or produced straight from Dodge. While comparing these two vehicle may be fun its not exactly a level playing field either if one car is modified and resold. If that's the case then let's take a modfied ZR1 and compare it against the ACR. In other word lets have a equal comparison by comparing vehicles offered straight from the manufacturer's production floor.

        This car IS available straight from your Dodge dealer just the way you see it in the vid. Don't believe me? Go to Dodge.com, select Viper, build your own, when you get to the options click the hardcore package and the competition group.

      The ZR1 looks like a handful...
      • 6 Years Ago
      Howdy... glad y'all found my video. Here's my blog entry on making the video and the analysis:
      http://blog.andibaritchi.com/2008/08/viper-acr-vs-corvette-zr1-side-by-side.html

      I saw some questions above about how the ZR1 and ACR handle. Judging by the video(s), the ZR1 looks delightfully neutral juts like the current Z06... while the Viper looks like it's a little more stable upto 9/10ths but then has harsher breakaway.

      That having been said, as I said in my blog post when I made this video.... the ZR1 was driven almost perfectly. Super clean lap. The ACR: nowhere close. Perhaps SRT wanted to add insult to injury and beat the record with the most unclean, poorly driven lap possible?

      Cheers,
      Andi

        "most unclean, poorly driven lap possible?"

        Not the words I'd use to describe a 7.22, but to each his own.

        The ZR1 wasn't driven perfectly however, far from it. It had much more of a tendency to get the rear out, which you could see limited the driver's ability to shoot out of corners onto straights compared to the ACR, which, thanks to that huge wing and R-compound tires, didn't have any drama coming out of corners.

        Never thought I'd see the day a Viper would outhandle a Corvette.

          Aman,

          I agree the ZR1 wasn't near as able to plant the power coming out of corners, but Mero clearly drove it to 98% of its potential. The one time he did mistakenly slide the car way too much exiting a corner and wasted about half a second, he threw out his right hand and waved it in disgust.

          Like you said, the downforce and tires gave the Viper huge grip and stability.... but whenever it did get loose, it's like Coronel didn't know what to do and started sawing at the wheel randomly. Smooth is fast - notice how fluid Mero's motions are compared to Coronel's.

          Mero's lap is a romantic dance between two partners, the car and the driver, who obviously know each other very wel. Coronel's lap is a quickie at the bordello just to get the job done.

          Cheers,
          Andi

      cheap trick by dodge. ACR is not a production car, and shouldn't be compared to ones like ZR1 or GTR on street tires. ACR should be compared to C6-R, 911 cup, or N24 prepped STI's for a meaningful result.
        • 6 Years Ago
        Really?

        Because you can build and price an ACR right on the Dodge webpage. Select "Competition Group" and you get the ACR package.

        Try again.

      After Days of research... ive come to the exclusion that the Corvette ZR1 is not the competition for the Viper SRT10 ACR. it has no competition at the moment... The ZR1 being a high performance sports car and the ACR being a high performance Track/Sports car. The ZR1's competition is the standard Viper SRT10 not the ACR. with that said you cant compare them... and also on the topic i hope Chrysler LLC. dose NOT kill the Viper...

      I like both cars but all you people saying the ZR-1 needs R compound tires to make it fair are missing the point. They are both bone stock cars ran as the manufacturers saw fit to build them. Right now Dodge has the upper hand because they chose to go a little more on the edge than GM and it worked. If you want to put different tires on the ZR-1 then you might as well put a new intake/exhaust, maybe a pulley swap, how about a couple of turbos on the Viper? The only way to truly compare cars is as they roll off the assembly lines. Anything other than that and you have people wanting something that makes it advantageous to whatever care they prefer. Yes the ZR-1 would be quicker with different tires, but the Viper would be quicker with just a 500rpm bump in the rev limiter. Nobody on this blog could get anywhere close to the times of either because if you could you would be out there practicing all the time, not being keyboard commando on here. As it sits if I could only have one of them I would have the ZR-1, bu give me lotto money and I'll have both parked in the warehouse.

      It looks like the Viper is more composed with all that extra downforce. I'm looking at the wheel & driver's hands and it looks like Mero in the ZR1 has to fight/adjust the wheel more often.

      Interesting to see if a proper tuner can outfit the ZR1 with an add-on aero package.

      But really, who cares? These are balls to the fire-wall cars and anything under 8minutes at the ring is blazing quick.
        • 6 Years Ago
        Agreed! It seems like the ZR1 understeers a lot, and you could tell the driver was frustrated with it near the end of the lap. The Viper was much more responsive, and I never thought I'd say this, but to me I think it would be easier to drive than the ZR1. Besides, the Viper looks much better too.
      • 6 Years Ago
      The ZR1, I beleive, was not driven by a professional driver, but rather a professional engineer from the development team. I'd sure like to see what a pro could do in both of these cars.
        • 6 Years Ago
        Yeah, but the Viper has that nasty rear wing.

        Downforce is key.

      Both car are very fast and very scary to drive. GT-R is a better choice.
