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.

You dodge fans can have all the fun you want you are not beating the z06 to the finish line, and sure as hell not on a road course!

This is all well and fine until the zr1 comes out!

If this is what they are doing to a Challenger, I cant imagine what on earth they have planned for the Viper.Dodge always is a patient company, letting everyone else play their hand, then.....they hammer you with something unreal. I like GM products too, don't kid yourself. My next project is a Pontiac Lemans with the supercharged LS motor (crate from GM, affordable reliable and way cheaper than foreign). Im just glad the US is building these things. Its nice to see Corvettes and Vipers keeping right up and hammering their Import competitors.

Both great cars
Hellcat straight liner, only great for the fast guys that can't turn along with Cruzers and Posers
Z06 all around competition spanker even better for the guys that know how to turn!!

So it's official the Hellcat is quicker and faster with a top speed of 199 mph. Running on the stock tires 11.2 seconds in the 1/4 and on drag tires 10.8, both times have been certified by NHRA. Trap speed for the production tires sits at 125 mph, while the drag radials increase the trap speed to 126 mph.

With the 10.8-second quarter mile, the Challenger SRT Hellcat will beat a 2012 Ferrari 458 Italia, a McLaren MP4-12C and match the 2013 Nissan GT-R out there on the drag strip. Now that's performace!!!

From the car & driver blog Oct. 1st 2014:

"Chevrolet claims the Z06 sprinted through the benchmark 0-to-60-mph measure in just 2.95 seconds and that it annihilated the quarter-mile in an equally impressive 10.95 at 127 mph. Those who opt for the seven-speed manual transmission will have to be content with claimed 3.2- and 11.2-second (also at 127 mph) times. "

Sorry Mopar fans.

Many of you are missing the point entirely. The Z01 should beat the Challenger. One is a ground up designed sports car. The other is a 4 door sedan used to pick up the kids after school, and grab a trunk full of groceries where you actually sit upright in the seat and not laydown. Let's try the 1/4 mile again with 5 people in the car and some boxes and bags from Walmart and see how we do!! Wait...oh ya...Corvette...FAIL! Will a Corvette even be able to carry a case of beer to the finish line for the after event party?

I agree, Mopar or no car, I have been a fan since the sixties. That isn't going to change now or ever. I like Vettes but I would never buy one I couldn't sleep knowing there was a Chev in my garage. I hate how these people put a Corvette, a sports car up against the Challenger a Muscle car. I really think it is more of a grand tour with balls. I think the main problem is they don't have anything that directly competes with the Challenger so they compare out of class. The same thing happened with the Shelby and the 392 that was stock and the Shelby is not. There was a huge price difference Shelby being higher by almost double. If they had put the difference into the Challenger and compared them the story would have had a happier ending for Mopar.

I am a die hard chevy fan but dodge is somewhat impressive but then again after getting your ass kicked in the muscle car segment for 5years straight..i think you'd have to be. 700Hp nice but doesnt mean anything. With all that weight Chevy is confident they'll put the zl1 against it and not get embarrass then unleash big bro zo6 on them!

Why doesn't everyone quit comparing a car that weighs at least 900 pds more than it's so called competeter motor for motor it s clear who is the winner!!! Last time I knew weight is let's get real. As far as the zl-1 that is a turd. Every time Chrysler is on top everyone calls foul just like back in the day with the hemi the other manufacturers kept wineing and nhra kept adding weight to the hemi cars until they were no longer competitive and Chrysler threw in the towel. Years later nhra president Wally parks appolagised to Ronny Sox saying he was sorry for being so unfair to Chrysler and he was wrong.end of story.!!!!!

Total Chevy fan but Dodge is impressive. Agree on quarter miles and turns but what about top end? Is it possible the Hellcat has sufficient horsepower to overcome its probable aero disadvantage?
By the way, I think the Corvette would have an additional advantage in the 1/4 with probably better traction as well as less weight.

Chukwuma (not verified)    July 3, 2014 - 8:07AM

WELL SAID!!!!! Read the other article and this clarifies every you stated in the other article. I am a fan of both but Challenger is a FAT beast!!! Vette is much more aerodynamic than the Beast!!!

Who friggin cares? The Challenger & Vette are totally different cars. The true comparison should be between the Helical & ZL-1 Camaro.

Rat Patrol (not verified)    July 3, 2014 - 9:54PM

Pretty lame comparing a two seat spirts car to a full weight muscle car.

Lets see how a Craparo goes against the Hellcat - Now THAT would be a fair fight.

We'll leave the Corvette ti the new 750 HP Viper....Oh oh....I promised I wouldnt let that slip...:o

pickle (not verified)    July 3, 2014 - 9:59PM

the hellcat has a backseat. End of the contest as far as me and my family-car needs are concerned. Any car with a backseat that can run even close to the new Z06 is a winner.

scott yandell (not verified)    July 4, 2014 - 3:14PM

Your weigh estimates are way off the C7. Every C7 weights at least 3575 or more. Z51 is over 3600 pounds :), they are pigs. The ZR1 still is the fastest production car ever and will maintain that until chevy puts at least 700 hp in the vette.

Rat Patrol (not verified)    July 4, 2014 - 7:26PM

@ Scott Yendell - Why would anyone believe a word you say when you dont even know that the Bugatti Veyron is the fastest production car in the world with a top speed of 260mph!!! And there are other supercars that ate significantly faster than the 206mph of the ZR1!

Rat Patrol,

Bugatti Veryron is NOT the fastest production car in the world. Hennessey's Venom GT is. It's all over the record books. Check the facts man. By the way, it's powered by an LS2.

@ Foreignbishop - I'm afraid my facts are just a little bit more correct than yours..

The Hennessy qualifies as the fastest accelerating car according to the Guiness book of records, but has not been made in enough numbers to qualify for the top speed record as a "production car".

So at least one record book says you are wrong.
