Last month, Mazda Raceway Laguna Seca to perform one of the first head-to-head comparisons between the current Chevrolet Corvette ZR1 and its newly redesigned nemesis, the SRT Viper. We've already gone over the article and amazing photographs of this epic all-American battle, and now, MT has provided a video of the deed in its latest "Head 2 Head" installment.

As we've already reported, not only did the 'Vette come out victorious when it came to lapping Laguna Seca, but it also set a new track record for a production car with a time of 1:33.70 beating the previous time by 0.2 seconds and beating the Viper by more than two seconds. In straight-line performance, both cars ran an identical 11.4 seconds in a quarter mile sprint. In the video, MT's drivers point out that the ZR1 has better braking and cornering on the track while the Viper's raw power and rough ride were mentioned on multiple occasions. One of the interesting notes is that the video points out the "deafening" cabin noise and "rock-hard" seats in the Viper, but SRT responded by saying both issues will be fixed by the time the car goes on sale.

Scroll down to watch the whole video showing both the Viper and the 'Vette tackle one of the toughest tracks in the country.

      We should just be glad these two cars exist and they're made in the USA....slightly different flavors, cuz it's nice to have options..

      Same power, same weight. 14" steel brakes vs 15.5" ceramic. 2 seconds less laptime. What a surprise!

      Talk about what's on paper all you want, but the Viper and 'Vette have always been two different animals. The Viper can barely fit a couple of briefcases in it's "trunk" while a Corvette can fit two golf bags. The Viper has always been a more hardcore unforgiveable dish. The Corvette has been a vehicle you can take on a road trip and also thrash on a track. If you want to talk value and practical usage (difficult for me to say when we're talking about two seater 600+ HP cars) the 'Vette wins.

      I attribute a lot of this to how long each has been in production. The ZR1 is on it's 5th year of production, and it's polished to a high sheen. All of the rough edges have been addressed. Ever watched a video of an 09 ZR1 being driven at the limit? It's ALL OVER THE PLACE. The driver is madly sawing at the wheel constantly to keep it in check. That's the challenge facing the Viper. It's a brand new chassis, and they're still getting it dialed. It's going to be a year or two before they get the suspension, brakes, and interior dialed in. That being said, I think I still prefer the Vette, for a number of reasons. First off, sound. While this is the best sounding Viper to date, and a great sounding car, it's still not as visceral and exciting as the ZR1's angry roar. I tend to prefer V8 sound to that of a V10 anyways, and the ZR1 is one of the best sounding V8s I've ever heard. I never thought they could make an LS sound that good. Secondly, content per dollar. It just seems like the Vette gets better kit for less money. While the Vipers brakes are anything but bad, they simply don't compare to the Vette's monster CCMs. Everywhere but the interior, it just seems like the Vette has a slightly better level of tech in most every regard. And finally, aesthetics. I just can't get settled on the new Vipers looks. I'll see it from some angles and the new Viper will look simply spectacular. The I'll see it from a very slightly different angle and the proportions will look strange and the whole car looks kind of goofy. The Vette, while I never get that "my god, that's gorgeous" moment that I get from the Viper, never looks bad from any angle. It's always an attractive car. So all in all, I prefer the Vette.

        The "new" viper is LARGELY based on the old platform. The viper, corvette and the 911 have been doing the same things for about 20 years. Evolving the design and impoving based on lessons learned, not throwing everything away and starting from from a new. If it wasn't better than the old one it would have never been put on sale. The fact is, Viper is not keeping up with the curve, and it never has. It sells on image and sex appeal, not being the fastest amaerican sports car.

          Until they finally got the ZR1 nailed down, the Viper ACR WAS the fastest American sports car. And while I agree to some extent that the new Viper is very similar to to older model, it's still a new model with all the rough edges that entails, and the ZR1 is polished up after 5 years or incremental changes. I think here in a few years the Viper will be quite a lot better and a better match for the ZR1. At least until the C7 ZR comes out, and Chevy starts facing the teething issues again.

          @ protovici - Hmmmm you are the one who needs to do some research my man. As with most vehicle produced in any volume above 200 or so a year items come in to the plant as modules to a large extent. I.P., HEVAC systems, wheels/tires assy, brake assemblies, bodies etc. The viper is made on an assembly line, so it is assembled from parts and modules, e.g, roof linings, etc. Even a lotus nor Aston Martin is hand crafted like they used to be. Basically Viper is manually assembled because for the limited numbers produced human labor is cheaper, even in Detroit, than expensive robots that can assemble 60 and hour and the maintenance that comes with them in the night time hours of non assmbly times. Sp Pro....whatever your name is....I suggest that you keep your postings to yourself as you clearly have never been to a plant or worked in one...far from completely wrong you are ignorantly wrong.

        Multi cam engines are not the best solution for power to weight. Pushrod engines have a superior power to weight ratio. Multi cam are best when there is a displacement limit, like in F1, FIA Rally etc. Aircraft piston engines are almost exclusively pushrod for that reason. Another advantage that V-type pushrod engines have is lower center of mas. That means better handling for the car. Informing one ignoramus at a time....

          @edward.stallings
          Here's to informing the ignoramus Mr Stallings. Power is a function of the amount of air one can pass through an engine. Pushrod engines are invariably two valves engines, anyone know of a 4 valve or 5 valve push road engine ? This is a reason why F1 engines run at 19,000 rpm for air flow through, to produce power. Torque is then created from this Power in the transmission. I can't believe that you are serious. No pushrod engine would come close to being able to run at 19,000 rpm without serious valve train harmonics problems that would tear it to bits around 12,000 rpm. Engine designer sacrifice a slightly higher CofG for the air flow through power, and with engines that run at these high rpm's use electro/pneumatic valvetrains that are lighter and give a lower CofG that pushrods.... WRONG again

        @Lucky Vanos
        You have no idea what you're talking about. The viper's motor has variable valve timing on the exhaust valve which is essentially vanos except on the exhaust cam instead of intake. The leafspring in the corvette is very different than the leaf springs in trucks in terms of function (see corvette leaf spring wikipedia page). GM also pioneered magnetically controlled suspension. It's the reason the zr-1 receives so much praise for its dynamics and one of the main reason's its one of the fastest cars around the nurburgring. Also, either of these dinosaurs will prove to be more reliable than an overengineered German car.

        The fastest Porsche is # 12 on the Laguna laptimes HERE http://www.motortrend.com/features/laguna_lap/ There are two viper variants ahead of it and 2 corvette variants ahead, both pre-2013.. and this is the 'mighty' GT3 RS, suppossedly the badest Porsche can do. The Z-06 would lap it at laguna within 5 laps. and that is a 2011 Z06, not the updated Z06 Carbon which would probably catch up to in and pass inside of 4 laps, you have not even brought out the ACR or the ZR1. Porsches are nice, but numbers speak for themselves. There is no need for complexity if it does not achieve anything. That is why we won the last war.

          I think the whole discussion is silly. Just like nurburgring thing, so many factors involved. For example, regarding porsche, you can see that there is only one GT3 RS entry, meanwhile we have multiple Z06/ZR1/ACR. It's pretty much possible that the driver (Randy Pobst?) is prefer (and often drive) american sportscar than the rest. That's not really fair as comparison. And uh, GT3 RS is not supposedly the baddest porsche, GT2 RS or even Turbo S probably. You also can see how that GT3 RS (which has more than 90hp less than Z06/ZR1/ACR/GTR), came only 0.05s slower than mighty GT-R. Seems legit? Take the numbers for fun, no need for nationalism bullcrap. Also in the last war, you (USA) brings much much more complexity than your enemies, and It's hard to justify 'won' when you gain so little and bring many more problems (your money depleted, your public image destroyed, insurgency, sectarian violence, and increase international terrorism) at the same time.

      The fact that the Corvette is wearing Cup tires explain most of the performance. Not to take a grain of respect off the ZR1, but the test was just unequal on that point of view. When BMW release the 320si as an homologation special for the WTCC, an European magazine tested the road car with road tires and slick tires. It was 10 secs faster on a 90 secs track. That's how much tires are worth. SRT better puts some CC brakes on the Viper though, even if both CC brakes and Cup tires on road cars make little sense.
        Rotation
        • 1 Year Ago
        @johnnythemoney
        I'm sure you're right. Both drivers say the Cup tires are a big deal, so surely they are a big deal. Maybe Dodge should look into the idea of getting better tires. As to the brakes, you shouldn't need carbon brakes to get through just one lap at Laguna without fade starting in. They have more work to do other than just jumping right to carbon. I'm sure Dodge can get a handle on this though. I can't believe fast156GTA is calling this apples and oranges. Both cars have about $20,000 worth of options on them (including the SRT Track Package mentioned) and the Viper costs $20,000 more to start. So I don't think I can just write this off and say I shouldn't expect the Viper to be able to match up on braking or tires.

          The article says the car has the tires. http://www.motortrend.com/roadtests/coupes/1212_2013_chevrolet_corvette_zr1_srt_viper_gts/specs.html Tires: 295/30R18 94Y; 355/30R19 99Y Pirelli P Zero Corsa And personally those brakes look like Stoptechs to me. But even if you think it has the tires and not the brakes, you aren't going to get the whole 2 seconds back by just getting the Stoptech brakes. And where do you think that $20K is going to if it doesn't have that track pack? I didn't say it was serious fade on lap 1, but if it's minor fade after 3/4 of a lap, it'll be serious fade sooner rather than later.

          @Rotation
          I agree, fading brakes during the first hot lap (that's what we know) are not good at all, but if that was serious fade he wouldn't have been able to finish the lap decently. Too little to really judge on, but yes, they definitely need to up their game in this category, the CCB suggestion is more of an option rather than standard equipment. Some are saying the Viper has the Track Pack, some don't. Regardless, brakes and tires alone are worth those two seconds. I still think CCB are somewhat useless on a road car, but if you are going to bring it to the track, then they are almost a no brainer. Bottom line, these tested Vipers are still pre-production cars, and as it's often the case, automakers shouldn't give them to the press and not expect some critics in aspects which are not finished (like the seat). Perhaps the brakes weren't up there either.

        No - the reason that it was quicker was that the chassis was more refined and developed. A lot of the uneducated unwashed masses believe that something that has a stiff suspension is quick. Not so. Look at the really fast sportscars on track, Audi, Porsche, etc - they can but the power thru the contact patch so much more smoothly and earlier. You can per-heat the tires with warmers if you like, but if the suspension is out of tune with the tire frequencies then it will never be quick. Wrong

        "but the test was just unequal on that point of view." So then wouldn't it be fair to say that every test that pits RWD car against an AWD is unequal? Or any test that has a standard H-shift versus a paddle shift dual-clutch? Well, clearly they're not equal, but that's part of the point... No two cars will ever be equipped the same. JUst because one car utilizes a piece of technology than the other doesn't, doesn't make the comparison any less valid. Tires are technology; they are just as much apart of the car as the transmission, brakes, steering rack, and engine. When the next 911 turbo dances all over the C7, I highly doubt we'll hear anyone complaining that it has a super-sophisticated computer controlled AWD system, thus yielding the test "unfair". Kudos to any PERFORMANCE car using the best performance tires. All that means is that much better.. it's not unfair because any car can have cup tires so should it choose.
