2013 SRT Viper GTS Track Test

2013 SRT Viper GTS Track Test

Testing SRT's 640-Horsepower Supercar


Edmunds tests hundreds of vehicles a year. Cars, trucks, SUVs, we run them all, and the numbers always tell a story. With that in mind we present "IL Track Tested," a quick rundown of all the data we collect at the track, along with comments direct from the test drivers. Enjoy.

After a disappointing 2011 and 2012, the Viper is back. It's got more power, less weight and, somehow, wider and more aggressive tires. It's a monster, and after driving the new Viper way back in September, we finally wrangled one of just a few on the planet (a pre-production unit, actually) for this World's First performance test of the 2013 SRT Viper GTS.

Just don't call the 2013 SRT Viper GTS a Dodge. After a decade of knowing the fearsome muscle car-meets-supercar as the Dodge Viper, the bigwigs at Chrysler have rechristened the snake for 2013 as the SRT Viper.

To avoid any future confusion, let's just call it "that crazy thing with the 640-horsepower pushrod V10 that's only available with a manual transmission."

Yep, while everyone else is either downsizing or adding tech features to increase efficiency (see the new Chevy LT1 in the 2014 C7 Chevy Corvette), SRT did not. Instead, it simply tweaked the formula of the 8.4-liter 10-cylinder and managed to crank out an additional 40 horsepower. SRT also looked to the scales to increase the performance of the new Viper. Thanks to a new chassis and carbon-fiber body panels, the SRT Viper is down about 100 pounds from its Dodge predecessor, while having 50 percent more torsional rigidity.

You don't need to be an engineering whiz to know that this combination is going to produce a staggeringly quick car. To find out how quick, we took a brand-new 2013 SRT Viper GTS equipped with the Track pack (R-compound Pirelli P Zero Corsa tires, two-piece Stoptech brakes) out to our track.

Spoiler alert: Whatever you call it, it's fast.

Db @ Idle: 58.0

Db @ 70-mph Cruise: 77.0
RPM @ 70: 2,000


Acceleration: Launch control is fairly worthless on our low-grip test surface. Its 5,000-rpm base is too high and its closed-loop throttle manipulation (using front wheel speed) is both too slow and not effective enough. Basically, launch control resulted in a big burnout. I chose a 3,000-3,500 launch rpm and had the best luck with a little clutch slip rather than a dump. Shifter is awesome — much better than before. Never missed a gear.

Braking: Solid pedal feel and good response. Consistent performance, but these (optional) P Zero Corsas are clearly less sticky than the optional Michelin Pilot Sport Cup rubber on the Z06 and ZR1.

Skid pad: Heavy understeer attitude, but massive grip. More throttle equals more understeer. Won't respond to lift throttle, which is probably good in a car with limits this high. Steering is direct and immediate. Ran all handling tests in "Street" damping, as "Race" was too stiff and made the car nervous. Feels like this level of damping is really only appropriate at high speed.

Slalom: Because of its limited visibility, the Viper is harder to place than some of its competition, which resulted in hitting more cones than normal. Still, its 73.7-mph speed here is telling. It's stable and relatively easy to control in rapid transitions. Doesn't feel like it wants to kill you anymore, but its limits still demand respect.

The manufacturer provided Edmunds this vehicle for the purposes of evaluation.

    Numbers that are very strong, but won't scare a 911 Turbo any. But it did tie or beat the ZR1 (4.0/101/72.8/1.02) in all tests. But a new ZR1 should be with us in about 18-24 months

    Pretty disappointing that 'traction control' doesn't control traction. And you get less than stellar acceleration times as a result. That ain't going to help with the marketing and neither is the heavy understeer.

    No she isn’t a refined German supercar. And I bet you that no SRT Viper is ever going to complete finishing school in Italian. But the new SRT Viper looks great, has a new civilized, livable interior and takes off faster than a monkey with its butt on fire. Most importantly I bet if I were to get a new SRT Viper out on a track and give it some stick I would have so much fun that I would be in danger of experiencing seizures as a side effect to the intense laughter! Finally while not a blue-blood exotic I am happy to take pride in it’s North American engineering and manufacturing. It also doesn’t hurt that it costs many tens of thousands of dollars less than those blue blood exotics too! SRT, Chrysler and Fiat I bet you have a hit on your hands in the new SRT Viper. Let’s see, if I sell my children, get a second mortgage on my home, and rob a small bank on payday . . .

    The interior is pretty damn sweet. And no slushbox! For men only.

    Quck car. I cannot believe I am the only person to comment. Where is everyone else?

  • agentorange agentorange Posts:

    OK, so in the new format you cannot see comments until you are logged in and have made a comment? Talk about user hostile. This had better be changing 12/17.

    Did Autoblog buy Edmunds? Because that's where you seem to be driving everybody.

    I hate coming here. Please don't delete the old site. Just upgrade the messaging system and keep it moving. Well back to the road test...Man that snake is fast!

  • saunupe1911 saunupe1911 Posts:

    I don't believe this car is meant for the 911Turbo or GT-R. It was meant for the ZR1, R8 GT and a few other so called exotics. Soooo SRT, when is the 911 Turbo and GT-R fighting ACR coming! lol

  • jeepsrt jeepsrt Posts:

    I would expect it to be faster, Motorweek got better #'s from a Mustang GT500. Also, hate the new layout.

  • mej2 mej2 Posts:

    Although this new Viper is probably better in every respect to the older one, I still think its design is kind of blah. The car looks virtually identical to the out going model except for the newer headlights (which I don't like). Just my two cents.

    0-60 with 1-ft Rollout (sec): 3.4 (3.7 w/ TC on) Price: $122,390 (base GTS price) Unproven reliability with sub-par performance with a base price of $122K, Dodge what are you thinking?

  • ru_90 ru_90 Posts:

    jpadayao 0-60 times do not make a performance car. In fact, they're irrelevant to how well a sports car performs. There are some great sports cars that have 0-60 times above 4.0. The Viper has always been traction challenged. The GEN V Viper in this video is struggling to gain traction upon launch. Even with launch and traction control. However, how can you call its performance sub-par? Is it because its 0-60 on this particular test. I've already seen lower numbers published by another site. Plus, the other test results (i.e. slalom, Figure 8, Lateral G, braking) rivaled any other car they have tested. Unfortunately, you chose to focus on 0-60 only.

    testing testing Man, in stinks in here compared to Insideline. Can't even do freaking automatic paragraph break.

    Sorry, just testing out this 1990's website. This is my first line of text. I wish to insert a paragraph break here. This is my second line of text. This is my first line of text. I wish to insert a single line break here.This is my second line of text.

    Man this UI sucks- are those frames on there. Is this 1998?

  • zr1man zr1man Posts:

    Just saw a new Motor Trend article where the ZR1 blew the doors off a new dodge viper.

  • m3hunter m3hunter Posts:

    How does it compares with the late great '10 Viper ACR?. Poor choice of tires, I bet Michelin Pilot Cup tires, where a better choice for this super car. I wonder if it's going to be able to compete with the new Corvette. Because in another article this new Viper falled short to the present Corvette ZR1.

    Where is this new Viper lap time from the Nurburgring track?
