Dodge Viper ACR Unofficially Laps Nurburgring in 7min 22.1secs

Take that Nissan and General Motors, you thought you had the Nurburgring record in the bag, but you didn't see this one coming. The Dodge Viper ACR has lapped the famous circuit in just 7 minutes 22.1 seconds, slicing more than 4 seconds off the time of the Corvette ZR1 and around seven seconds off the time of the Nissan GT-R.

The story behind the run started when the Viper Club of America got so pissed off at seeing its arch rival take the lap record, that the bugged the Dodge Street & Racing Technology team until they relented. The team then hired the ring for half a day on August 18th, shipped not one, but two Viper ACRs over to Germany and hired a pro WTCC driver Tom Coronel who has experience of racing in the 24 hours at Nurburgring.

Apart from a Racetech seat with a six-point harness, both of the ACRs used in the run were factory spec fitted with the Hard Core package. This package is popular amongst 10% of the Viper's customers, it sheds 40 pounds off the curb weight by removing a number of non-essential components such as the audio system, trunk carpet, rear cabin sound insulation, tire inflator kit, hood insulator, and steel battery cover.

Now comes the point of whether this lap record can be officially counted. The laps completed by the GT-R and ZR1 were reported to be in completely unmodified factory spec cars, however after early warm up lap times of 7:42 and a 7:35 some slight modifications were made. Colonel complained of some slight understeer on medium to high speed corners so the engineers stiffened the front and rear dampers.

The record run was a satisfactory conclusion for the team however there is belief this model could get well below the 7:20 mark.

The Viper is probably the worlds greatest sports car, and this is for suckers who say Vipers are only for drag racing, Eat It.

by Xanavi23 | August 28, 2008 6:15 PM
Xanavi - I know, I never implied that you were comparing them. I was just stating that the three cars are in their own league.

As for the viper being ugly, I'd have to disagree. the car is a beast and sounds like one, just wish it was more driveable on the street. It's just like the Vettes, too much torque on the rear wheels in the first and second gear. Hopefully they the ZR1 has fixed this error.

by dmanero | August 28, 2008 8:01 PM
Right...my friend wishes the Viper was more drivable on the street as well. He sold his Viper 2weeks after buying one because it was so uncomfortable and scary to drive.

He should've adjusted his driving style...but everytime we merged into traffic the tail would slide-out.

But it is a beast of a car! If only you had your own private road to not worry about hitting someone in the next lane when the tail slides out!

by schizo0223 | August 29, 2008 5:39 AM
that's all and well that they beat nissan and GM. But both the cars, (ZR1 and GTR) are unmodified, but the Viper, is fully tuned and modified. so you really can not compare these cars with the viper.

And on a diffrent note. The Viper could be even faster if thet added traction control and launch control.

by dmanero | August 28, 2008 6:40 PM
Im not comparing the GT-R to the ACR for one as they are completely different cars. Im comparing it to pure Sports cars like the Zonda and CGT that the Viper beat on the Ring. It beat them, while being cheaper and offering the same race car for the street mentality. As for being full-tuned ? wrong, it has Full-race suspension and aerodynamics but the engine is still nowhere near its limits and the chassis could also be further modified. Point being, the ACR is still a street car and it can take on supercars that cost 5 times as much...not too bad i'ld say.

by Xanavi23 | August 28, 2008 7:22 PM
It hasnt won too many le mans races recently though has it , cough "AUDI"!

by Bada_Bing | August 28, 2008 6:41 PM
Completely different classes so you can't really Compare Audi's wins to Dodge/Oreca's. They are 2 totally different classes and both are equally admirable as BOTH cars won their most important wins during a time in LM racing when there was VERY stiff competition.

As for Dodge, Prime Time racing is running a Viper Comp. Coupe in ALMS and they're getting better although the time. Look out for them next season.

by Xanavi23 | August 28, 2008 8:15 PM
Xanavi... the Viper is the worst sports car ever made.

by Xenicide | August 28, 2008 6:46 PM
Ignorance, plain and simple.

by Xanavi23 | August 28, 2008 7:19 PM
Well, it depends on who you ask. It's the classic case of old tech vs. new tech. Personally, I wouldn't say the worst ever made but imo, it's up there. I don't mean to be anti-domestic/American here; I do have some respect for Chrysler/Dodge for even trying, but such a large displacement places the Viper in a class that's unfair to the competition. Still, it ends up barely beating it, sometimes equaling or losing to it even though it has a power plant that's, in many cases, twice the size. Instead of relying on ones abundant resources, perhaps a bit more engineering, refinement, and reliability could earn the Viper some additional respect from the tech crowd. I realize it's no F-1 car but come on, using an 8.0 liter V-10 is absolutely ridiculous imo.

by RobERob | August 28, 2008 8:01 PM
Took the words right out of my mouth Xanavi

by gmfan09 | August 28, 2008 8:02 PM
Yea but you see, Rob, the Vipers engine is huge so while the power output might not seem like much it has one benefit thats far more important. The car makes 600hp from its engine with VERY little strain any the engine or any of its components, it will last long. In the world of racing, this means the car can run for hours without problems, as witness by Team Orecas countless wins in Le Mans series as well as the Race. On the road, the Vipers unstrained power equals the Viper motor will last 3-400K km before any major service is needed, provided its looked after. Which can't be really said for this cars European competition, to keep those cars going on high mileage you have to shell out ALOT of money every X amount of Klicks to keep it running well. You can't knock the Viper for not being the most sophisticated Sports Car, but even though it is old tech...it works, it puts down fast laps, gets decent gas mileage(25-26MPG HIGHWAY!) and won't brake the owners bank too hard to own in the long term.

by Xanavi23 | August 28, 2008 8:12 PM
My buddy has a Ram SRT-10 with 40,000km and it already has a tick in the engine, and it doesnt get anywhere near 25mpg on the HWY maybe half of that, it averaged about 2mpg on the race track. So i don't know how accurate your info is.

by radmeister | August 29, 2008 12:32 AM
the ram srt10 is a truck... aerodynamics and weight kills its fuel economy just as much as its engine. Don't know where the 25/26 mpg came from, it's epa number is 22 mpg highway. Which is pretty good, it's better then every S and RS branded Audi, any M series bmw, any AMG, the ZR1 (the other corvettes get better), and even the Nissan GTR. Large displacement does not equal poor fuel economy or emissions. Which is again proof why the ppl who post here know nothing about how cars work. Or how useless the hp/liter ratio actually is.

by joe_limon | August 29, 2008 1:00 AM
also, to your buddies truck, you admitted that he drives it on the track. No wonder it has a tick, 40,000kms and track days? that guy is hard on his truck, fortunately for him it won't cost $20,000 to fix as would a similarly powered European vehicle.

by joe_limon | August 29, 2008 1:04 AM
Well said joe. And the reason the europeans have engines with lower displacements is because they are taxed on engine displacement. Here in American we aren't so who cares. I don't

by gmfan09 | August 29, 2008 1:39 AM
Radmeister, Joe already answered your post. You buddies truck is a truck...it weighs 1000lbs more than the Viper and has much more inferior aerodynamics. Also your buddy drives his truck on the track, so there you have it, of course there would a tick.

25MPG was a rough guesstimate, ive talked to a owners of older Vipers and those can average 25MGP highway However, this gets 22MPG, which is alot better mileage than any European sportscar thats as fast as this is.

by Xanavi23 | August 29, 2008 2:19 AM
The Viper is ugly...and the factory stock viper has been beaten by the zo6...and the Zr1 lap record was done by Jim Mero who is an engineer not a professional race car driver. Can you imagine if John Heinrachy, (the same guy who ran the CTS-v around the ring in 7:59)took it for a lap.

by Roger426 | August 28, 2008 7:00 PM
Anyone who runs a 7 20 on The Ring is a real race car driver.

by Deuce_Coop | August 28, 2008 7:46 PM
The car is bottoming out quite badly in places, it's too low and too stiff for the Ring. A race car for a hotlap, not a proper challenger to the factory ZR1 and GT-r cars imo.

Poor lap too, missed shifts, not always the perfect line, there is more time in that car yet.

by Voss | August 28, 2008 8:27 PM
The driver missed a shift at 2:12 of the video. Probably lost a second there....

by AG4 | August 28, 2008 8:49 PM
un official? o

by great_supercars255 | August 28, 2008 10:10 PM
ok...a heap of American junk outran pretty much everything....I hate to say its its as impressive as it is a moccery to be honest hahahha its cool ...

by gorgonzola | August 29, 2008 12:12 AM
You just have to appreciate this car. Really

by gmfan09 | August 29, 2008 12:50 AM
that's impressive... but i must say... imagine how scary it is to actually drive/race this car around the ring. lol this cars a BEAST... i'd feel SAFER in the GT-R., but respect to this either way

by carcrazy1234 | August 29, 2008 4:29 AM
The Z06 has not beaten the '08 Viper in any test I have seen.

by evile | August 29, 2008 4:30 AM
I have to admit you guys sell the Dodge Viper, last time I was a fan was when that Viper show was on tv :D but yawl make it sound real enticing...

I do wonder though... what if the ZR1 and GT-R also got these "slight" modifications... hmmm...

by Decypha | August 29, 2008 9:34 AM
viper is a really dam ugly car imo...doesnt turn heads and hold em still. and alot of roads are not made for these vipers, if u own a track or have a garage at one, ur viper got a use, if u try to even commute with em, prepare urself a set of new bumpers for the dam road is gonna bite on it hard

by dimeNIckel | August 29, 2008 10:07 AM
looks are personal opinion, i LOVE the look of the Viper. Its a Viper, and only looks like a VIPER...not even remotely copying any design traits from other cars while looking menacing as hell.

by Xanavi23 | August 29, 2008 2:51 PM
This is hardly an achievement. Wonder what the cost difference is between these cars? That alone should make this little exercise a moot point.

by DonnyBravo | August 29, 2008 2:34 PM
Cost? It already beat cars that cost more than three times as much

by gmfan09 | August 29, 2008 2:49 PM
between an SRT-10 and ACR version the difference is a total of $12k in the states, which are 2 seperate options. So as far as a "tuned" model goes, this car is still a HELL of alot cheaper than ALL of its competiton; LP560, 640, F430CS etc etc.

by Xanavi23 | August 29, 2008 2:49 PM
They must put the engine in rear not front they will get better performence like most european sports cars.

by Blackeyes21 | August 29, 2008 2:46 PM
That must say something if it beat them all with a front engine layout.

by gmfan09 | August 29, 2008 2:50 PM
zr1 was on street tires

by killercane | August 29, 2008 5:03 PM
So was the ACR it also used no traction control WHILE on street tires. Its funny how now the Viper has gotten even greater, people make it out as some sort of race car or still rag on it...lame.

by Xanavi23 | August 29, 2008 6:31 PM
So was the ACR.

by evile | August 29, 2008 6:11 PM
Comparing apples to oranges?? The only thing these cars have in common is that they are cars... If the ZR1 had a professional racer behind the wheel, that easily would have shaved off6 seconds off the lap time, never mind having all of those modifications of the Viper, and no radio, no air conditioning, no carpeting etc. etc. How about having cars equipped similarly, and both having a professional racer behind the wheel on the same day at the Ring, then we could get an accurate reflection of what these cars are capable of. The ZR1 proved that even a non-professional driver with about average skills can kick butt with this car. An average driver behind the wheel of the Viper ACR would have that car off the track so many times it wouldn't even be funny!

by Shark | August 29, 2008 6:59 PM
You're right. We are not comparing apples to apples. However, just imagine if Chrysler committed the resources to send a team of engineers to tailor the ARC to The Ring like Nissan and Chevy did. Both Nissan and Chevy were there for weeks. SRT made four laps and achieved a 7.22. Imagine if they had time to dial-in gear ratios and suspension settings? Finally, many have complained because the ACR has adjustable suspension and an aggressive aero package. What about all the elelctronic nannies the GTR and ZR1 have? The ACR is old school. It uses aero and grip to achieve its performance. I believe if Chrysler was committed to Ring times the ACR would have gone under 7.20. However, they are in survival mode right now. I hope they find a serious buyer for the Viper brand.

by evile | August 30, 2008 6:19 PM
yes, very fast indeed. have you guys seen how the gear stick shakes when he reves it or when it hits the rev limiter? i know this car has a bad finish, cause it's a track car. hope it is not the tranny, as americans make "great" transmissions..and especially with this humongous 8.4, 600bhp engine..i wouldn't be surprised that the tranny can't cope. and for sure after a lap like this im sure ur ears would be bleeding if you don't ware any era plugs. nice car overall.

by norther | August 29, 2008 7:27 PM
The ACR does have an AC unit. It has full carpetng in the cockpit, but the Hardcore package removes the carpeting in the trunk, radio, & the hood pad. It saves about 40 pounds off of the standard ACR. As far as the transmission, it uses a T6060 now. The shaking is from it hitting the rev-limiter as it is mounted by polyurethane bushings and not hard mounted like most vehicles. With all of the torque, front engine & RWD it needs to be able to flex or all that torque movement would be transferred into the transmission & not the bushings. I do agree that the ZR-1 was not driven by a professional, but Jim Mero has more seat time in it than anyone else and really but down a nice run with it. Can't we all just be glad that there are 2 American cars that have done extremely well on the international scene.

by jm24ond6 | August 30, 2008 1:46 AM
Viper ACR is fast but the GTR is fast AND sophisticated. I am well aware of the unfair hyper-criticism of haters who stupidly want US companies to fail without realizing that the US economy will perish if GM/Ford/Chrysler goes bankrupt, but criticism is warranted. Some people simply want better performance, better build quality, AND sophistication. America used to lead the world in design and engineering but now, too many of our cars are a celebration of times past using outdated technology when the rest of the world has moved forward in design and found a replacement for displacement.

Some of us want America to lead not just wave the flag and shout down those who are concerned and want soemthing better.

by sensei | August 31, 2008 5:56 AM
What you fail to realize is the Viper's rough edges are part of its character. Many find this lack sophistication appealing. If one can afford a Viper they could probably buy a GTR, Z06, ZR1, 911 etc. too. Yet, there is still a market for the Viper, and all of this year's ACRs are sold.

Although the Viper's V10 is considered a dinosaur by many, it is sophisticated. It's no longer based on a truck as many claim, and yes, it is a large displacement, push rod engine.

However, it is the first in-block cam engine with variable valve timing. Everyone raves about its horsepower and torque ratings, but few mention its rated at 23mpg on the highway. Thus, it has better mileage ratings than any Ferrari or Lamborghini, and more power and torque than any Porsche except for the Carrera GT.

by evile | August 31, 2008 5:22 PM
There is nothing that I fail to realize. You have say that inferior quality is part of the Viper's character to excuse it. Its like Harley-Davidson drones bleating on about heritage becaue HD cannot make anything high-tech. The Viper IS outdated and crude technology whereas the rest of the world makes better, more advanced, and cheaper cars. VW has now passed Ford as #3 in the world. WIll it continue to fall? Getting pissy about this fact will do nothing to negate it. Accept this or don't. You don't matter.

by sensei | September 1, 2008 10:39 PM
Sensei, you make no sense, to talk about the Viper being so out-dated and crude would require the Viper to be oh-so destroyed by its Rivals in so many ways...but its not;

The Viper is faster around many tracks than its rivals, it gets better fuel economy and its MUCH cheaper than most of its competition. The only thing its rivals have over it, is refinement and that doesn't necessarily justifying paying soo much more than the you would for the Viper. Especially since the Viper has them beat everywhere else.

by Xanavi23 | September 2, 2008 2:59 AM
You can ignore reality and lie about the Viper all you want to. Like a child unable to hear any bad words about his mommy, you show that you are simply not mature enough for the real world. Not everyone is an uncritical lover as yourself and we're not apologizing for accepting reality and having higher standards than you.

by sensei | September 6, 2008 4:19 AM
Considering the Viper SRT-10 ACR is essentially a Le-Mans race car for the road, this time is actually not that impressive. The car has an aero kit taken straight from their Le-Mans experience and makes about 1000lbs of down-force at 150mph. Add fully, independently adjustable suspension, Michelin Pilot Sport Cup Semi Slicks and we have an all out race car. The ZR1 and GT-R's times are much more impressive for cars that are essentially daily drivers. The normal Viper SRT-10's lap time is a measly 8 minutes, which is rather poor in comparison to the ZR1 and GT-R.

by gp900bj | August 31, 2008 9:09 AM
What about ALL the computers the GT-R NEEDS to get the job done, sure the Viper uses aerodynamics to help it but thats it man. The Viper uses aerodynamics, and GRIP to get the job done, no TCS, no ASM, no electro-suspension that compensates for weird car camber etc etc etc.

You people penalize the Viper for the one aid it has, but completely ignore ALL the aids the GT-R NEEDS to use because its so heavy. BS, no offense.

by Xanavi23 | August 31, 2008 3:14 PM
Actually, the ACR's time is very impressive when you take into account they broke the record in four laps. Both Chevy and Nissan spent weeks honing their cars in preparation for a record run. For months, we've seen video of the GTR either chasing or being chased by a 911 Turbo around The Ring. Chevy spent extensive time with both the Z06 and ZR1 at The Ring.

Chrysler is on the rocks. They cannot afford to invest millions in order to chase bragging rights at The Ring. It took pressure from devoted Viper owners for them to even send cars. They sent two cars and rented the track for a couple hours. In four laps they soundly beat both the ZR1 and GTR with customer cars. Imagine if they had an opportunity to play with gear ratios. The ACR would have been turning laps under 7.20.

Yes, the ACR has adjustable suspension and aero, and that may give it an advantage on the track. However, both the GTR and ZR1 have electronic aids that make similar adjustments on the fly.

by evile | August 31, 2008 5:43 PM
this is funny, put 8.3L into the gtr and it'll beat the hell out of the viper :D

by XtremeMaC | September 1, 2008 2:22 AM
Slap twin turbos on a Viper and...well you get the picture.

by evile | September 1, 2008 5:43 AM
Just in case you don't, slap Twin Turbos on the Viper with some rods and pistons and say hello to 1500whp+ courtesy of a decent dyno tuner.

As for the GT-R, just putting in the Vipers V10 doesn't mean jack...you actually have to know how to build a proper car around such a big engine. Which Dodge did as the Viper(not just ACR) has always been a competent track car. Point being is that Dodge has alot of experience building large displacement cars and it shows with the Viper, Nissan does not. Both companies are good, but its only right when an American car company has large displacement of this caliber.

by Xanavi23 | September 1, 2008 6:10 AM
Xanavi, put twin turbos on a VIPER and watch the rear wheels spin furiously and not move the car forward one bit. We've already seen a 1000hp+ VIPER fail at supercar shootouts before due to this very reason. All you shouters don't want to face the fact that power is nothing without control. This is why the GTR is so superior to anything coming out in the US. Defending mediocrity does nothing to make American companies advacnce to be more competitive.

by sensei | September 1, 2008 10:44 PM
Sensei, yes, power is nothing without control....but are you telling me you haven't seen the countless Viper owners that are running 7s,8s, and 9s in the 1/4 Mile, to get low 9s and better you would need drag radials, but high 9s could probably be yielded by a Viper with street radials. The Viper is a fine car as is, "if it ain't broke, don't fix it"....the Viper just smashed the record with very little effort and beat out cars that cost a hell of a lot more. It does what those cars are supposed to be just as good if not better. The only place it loses is on top end acceleration, and thats a result of its uber wide gearing which is a + because it enables the Viper to get 23mpg, a hell of alot more than any of the cars it competes against; "If it aint broke, dont fix it".

by Xanavi23 | September 2, 2008 2:56 AM
1/4 mile times? Please man, get real. You want to compare the Viper to international cars and it simply is not a circuit corner carver. The Vette is a better choice.

by sensei | September 6, 2008 4:28 AM
Well well it only took the US a V10 8liter and a boatload of time to finally beat a time.

by cush_ | September 1, 2008 8:29 AM
A boatload of time you say ? the Viper was first released in 1994~ since then it started out beating down exotics, in speed. Has continued since and has no stepped-up to the PINNACLE of sports cars, taking on pure Supercars that cost 6 times as much...thats pretty damn good for only a 14~ year run. The Viper challenged the Exotics/Europeans with its simple(but GREAT) formula and in reality as we see here, the Europeans still have yet to really answer back. There are NO cars in the Vipers price range, that can take it down or match pace, save for the GT-R and Z06,the ACR is even higher/better. Also you should all note, that the ACR package is available on both regular SRT-10 Vipers, you can pick just the suspension, or just the Aeros or both. This car is a pure street car while being a track-car, quit the non-sense about it "not being street".

by Xanavi23 | September 1, 2008 4:07 PM
Remeber the Bugatti Veyron it's engine is in the rear and mush bigger then Dodge Viper with 16 cylender and 4 turbos. They must take the idea from them they will make better performence around the track.

by Blackeyes21 | September 1, 2008 2:52 PM
Xanavi. My comment was not an attempt to ridicule the Viper for what it has. My point is that the ACR IS a race car. You cannot drive it to your local shopping center and pick up the groceries without extreme difficulty given it's ride height and that massive rear spoiler. It was designed exclusively for the track. So considering it is only 4 to 7 seconds faster than cars which were designed to be used as daily drivers the time is quite unimpressive. On equal terms, In equal road going specification, the Viper is 1/2 a minute slower than both the GT-R and ZR1.

Additionally your statement that the GT-R needs TCS and ASM to run a fast lap time is false. The GT-R has one TCS/ASM program called VDC. The record lap time was set with VDC turned completely off. Millen's 1:56.9 around BW13 was set with VDC off. Kurosawa's Sendai lap time was 4 seconds faster with VDC turned completely off than it was with the VDC in R mode. The car induces excessive under-steer with the VDC on as a safety measure, so race driver's turn the VDC off when trying to set lap times.

by gp900bj | September 2, 2008 6:10 AM
Im not so sure about that, a Super Moderator on another site i frequent has driven the ACR and while he says its a bit rough around town, its not nearly that bad and still retains some practicality. The spoiler doesn't reduce visibility much either, and the truck still opens so it could be much worse.

by Xanavi23 | September 2, 2008 3:48 PM
In front of me I have a German paper, Sport Auto nr 12 2004. In this paper, you can read about the Donkervoort German-Chef Michael Düchting, who was driving with his streetlegal Donkervoort D8 RS oround the Ring in 7. 18,10 minutes! The editor of Sport Auto, had earlier that year, made the Ring in 7.32,44 min. with a 10 cyl. Porsche Carrera GT. In December 2006, I visited Essen Motor Show, and do you know what I saw there? The new more "streamlined" Donkervoort D8 RS! Spec; 4 cyl. 2-litre Audi-engine 370 hp, topspeed 161 mph, 0-62 mph in 3,7 sec., 0-124 mph in 11 sec., weight 665 kilos (1464 lbs.) and the most interesting fact; 7.14,89 min around the Ring! They say nothing beats cubic inches. Now we say nothing beats lightweight.

by OPCVectra | September 2, 2008 11:16 AM
or you could have mentioned the 500hp/500kg atom and it's sub 7 minute time...

by joe_limon | September 3, 2008 8:26 PM
Come on. Comparing an orange to a lemon. Porches 911 Turbo is still the World Best Super Car. Better than Corvette ZR1, Skyline GT-R and the truck engine Viper.
