Revisited: 2015 Chevrolet Corvette Z06 Vs. 2015 Dodge Challenger SRT Hellcat

A while back I did a piece discussing the fact that the 2015 Dodge Challenger SRT Hellcat wouldn’t beat the 2015 Chevrolet Corvette Z06 and now that the Chrysler Group has announced the shocking power figures for the supercharged Hellcat Hemi – it only seems proper to revisit the battle between the two American monsters.

When it was announced that the 2015 Dodge Challenger SRT Hellcat would offer at least 600 horsepower and at least 575lb-ft of torque, there were a great many Mopar fans posting on Facebook, YouTube and many internet forums about how the Hellcat would allow the Challenger to beat the 2015 Chevrolet Corvette Z06. At the time, it was expected that the Z06 would pack 625 horsepower and 635lb-ft of torque while the Mopar lovers who expected the Challenger to beat up the Z06 to pack somewhere in the area of 640 horsepower. After reading these views from the Mopar faithful, I did a piece detailing why I didn’t think that the Hellcat Challenger would be able to compete with the Corvette Z06.

As a result of that piece, I received tons of comments and tons of hate mail from both sides of the argument with both Challenger and Corvette fans chiming in to tell me that I was wrong…even though I was actually agreeing with some of them. GM fans insisted that I was a moron for suggesting that the Challenger could beat the Z06, although those folks obviously didn’t comprehend the article since I was agreeing that the Z06 would win the fight. On the other hand, some Mopar lovers insisted that I was selling the Hellcat short and that it would be able to beat the lighter Corvette.

Now that we know the power figures for the Corvette Z06 and the Challenger Hellcat, some of those commenters and hate mail authors are insisting that I re-evaluate the whole situation.

Hellcat vs Z06 – a Tale of the Tape
it is official – the 2015 Dodge Challenger SRT Hellcat will make 707 horsepower and 650lb-ft of torque – making It the most powerful American production car of all time. It is also official that the 2015 Chevrolet Corvette Z06 will make 650 horsepower and 650lb-ft of torque. Based on the fact that the Challenger has a massive advantage in horsepower, Mopar lovers are clamoring that I was wrong and that the Hellcat will indeed outrun the Z06. The problem with that argument is that the Challenger is much, much heavier than the new Z06.

We don’t have official weight figures for the 2015 Chevrolet Corvette Z06 or the 2015 Dodge Challenger SRT Hellcat, but we can make some guesses based on the curb weight of previous models. The 2012 Chevrolet Corvette ZR1 weighed 3,333lbs and it is expected that the 2015 Z06 will be in the same ballpark if not a little lighter. For the sake of discussion, we will use 3,300lbs as the possible Z06 curb weight. The 2014 Dodge Challenger SRT with the 6.4L Hemi V8 weighs 4,160lbs and while there might be some weight saving changes made for 2015, the Hellcat’s supercharged system likely adds at least a little weight. People are expecting that the Hellcat could weigh as much as 4,300lbs, but since we don’t have any sort of official figures on the Hellcat model’s curb weight, we will use the weight of the current Challenger SRT as that is really a best case for the Hellcat model. In other words, the 2015 Z06 will likely weight around 3,300lbs while the Challenger SRT Hellcat will likely weight around 4,200lbs.

Based on those estimated weight figures, the 2015 Chevrolet Corvette Z06 has a power to weight ratio of 5.08 pounds per horsepower while the 2015 Dodge Challenger SRT Hellcat will likely have a ratio of 6.08 pounds per horsepower – giving the Corvette a clear advantage. The Hellcat Challenger will pack lots more power, but at roughly 900 pounds heavier, the Z06 will still have a significant advantage power to weight ratio.

Could the Hellcat Challenger Beat the Corvette Z06?
Yes. In the right situation, the 2015 Dodge Challenger SRT Hellcat could beat the 2015 Chevrolet Corvette Z06…but not without the help of a shaky driver in the Corvette. With the aforementioned horsepower to weight advantage, the Corvette Z06 should be able to beat the Challenger in a drag race unless the Vette driver blows the launch. With a bad launch or crappy shifts by the Z06, the Challenger’s 707 horsepower could be enough to allow the Mopar muscle car to get to the quarter mile marker first. However, with equally skilled drivers, the lighter Corvette should win the quarter mile drag race.

Where the Hellcat Challenger really shouldn’t compete with the new Corvette Z06 is in any race with turns – regardless of the available power. Although they are both high performance monsters, they are two very different types of performance cars so the lighter, lower and more nimble Corvette Z06 should crush the Challenger SRT Hellcat around any road course.

However, the moral of the story is that it is conceivable for the 2015 Dodge Challenger SRT Hellcat to get the jump on a 2015 Chevrolet Corvette Z06 and win a quarter mile race – but a well driven Z06 is going to very likely win every race between these two 650+ horsepower beasts.

Put Thermite Bombs on the Roofs!! Muscle Cars and SUVs cause Global Warming!! If you want a Fast Car, get a Green Tesla!!!
You can buy 2 Hellcats for the price of one Z06. Nuff said!
When they produce a car under $1 million that will beat my 2015 911 Turbo S then we can have a discussion - no reason to discuss silver or bronze metals.......
They did and it's called the 2015 Stingray Z-06 lol maybe you should buy one and beat yourself
Nick, where are you getting your information? The ZO6 is an awesome car for around $100K or any price for that matter but it cannot beat the Turbo S in most categories - Horsepower isn't everything - I have a 2014 Shelby GT 500 as well and it has more HP and torque than the ZO6 and can't do what he ZO6 does so that's not everything. Let me give you the performance specs direct from Car and Driver: 0-60 Z-3.0 S-2.6sec 1/4 mile Z-11.1sec S-10.8sec 0-100mph Z-6.8sec S-6.5sec 5-60mph Z-3.2sec S-3.8sec Top speed Z-185 S-198mph skid pad Z-1.19g S-1.09 - Seems Turbo S wins 4 out of 6. I would also offer that a professional driver would outperform the S on the track in the Z but I would say that an amateur would be best in the all wheel drive and all wheel steering Turbo S. Just saying the S is an amazing car, although it is twice the price.......
Hey Jake, First I love Porsche and have a 997; personally would have bought a GT-3 if it were standard, but i'm not an all wheel drive guy.... rear wheel and standard trans for me. But that said yes the TS is super car fast, wins more.... but not where it counts. Handling and Breaking that = faster lap times so the response was only to your comment about nothing can beat your Turbo... Sports Cars are not drag cars and while your specs win in a few bragging areas, the overall Crown go's to the Z06
My buddy just took delivery on a Z06 so I will have a chance to drive it. Unfortunately he got the stick so will lose even more time but still should be a lot of fun. However I am a Porsche guy thru and thru and believe that Porsche is one of the last true purists sports cars. It is always the benchmark everyone (US or abroad) tries to meet or beat. I never wanted anything other than a manual until I truly experienced the PDK. i would never go back to a stick again. Happy New Years and hope you enjoy your 997 as much as I have enjoyed the 9 Porsches I have owned.
I have a zr1 I'm dying to race a hellcat. Cause I want the charger.
Everyone wants to compare the Challenger Hellcat, a muscle car, to top end super cars. The Challenger Hellcat can not beat the z06 Corvette and nor should it. It was not designed to compete with super cars. Compare it to a camaro z28. That's the only other car in its class that even comes close. Now with that being said and being a HUGE mopar fan I would like to see a head to head with cars on the same class. It says a lot for dodge if the Corvette is the only thing Chevy has to offer that is even in the ball park of beating the Challeneger Hellcat. Now with the release of the charger Hellcat I would love to see a real head to head with the corvette. With dodge and Chevy boasting similar numbers for 0 to 60 and quarter mile times on the Charger and Corvette I think it would be an interesting match up to say the least.
Zo6 owner and soon to be challenger owner. I doubt any one can feel the diff of 1 or 2 tenths in the quarter. I'll take either car for fun. Zo6 for track, and dodge for tire ripping.
