2015 Corvette Z06 Power Figures Leak, Features More Torque Than Outgoing ZR1

The 2015 Corvette Z06 is going to be officially revealed on January 13, 2014 — exactly one year after the official debut of the 2014 Corvette Stingray. There will also be a live stream of the event, for those of you who will not be attending the press conference in person. Yet before that even manages to happen, it seems the performance figures of the 2015 Z06 have been leaked. And the horsepower and torque figures are downright brutal.

According to metadata (the  lines of text that show up under a link in search result) from Chevrolet themselves, the 2015 Corvette Z06 will produce a staggering 620 horsepower, and a ground-twisting 650 foot-pounds of torque, as seen above. Holy smoking tires.

The power bump is 115 hp and 180 lb-ft more than the outgoing Z06 with the already powerful LS7 7.0L V8 engine. It’s anticipated that the 2015 Corvette Z06 will utilize a supercharged LT4 V8 in place of a naturally aspirated engine. Even more impressive, is that the torque figure is 46 lb-ft greater than that of the outgoing, LS9-powered, range-topping Corvette ZR1. More eye-opening is that the numbers are not quite finalized yet, so we could even see gains from those estimations. The 2015 Z06, ladies and gentlemen, is shaping to be nothing short of a monster.

  2. Wow! Does this mean we can see 750 hp plus for the zr1

  3. I have predicted that we would see between 600-650 HP to all the whiners that complained that the 7.0 was going away.

    Now consider this. The CTS V may be using the same engine here too with only a small change here and there.

    I would expect the ZR1 or what ever they call it will make at the least 700 HP but I would not expect 750 HP.

    Note the torque here is important as this is what you feel pushing you in the seat not the HP.

  4. Whats making me SUPER curious if IF these numbers are true and of course arent the final figures yet, meaning it makes more power, and the ’15 CTSV uses this same mill, and since the C6 Z06 was down 50 horse to the current V, does that mean that since this thing could make as much as saaaaaaaaaaaaaaaaaaaaaaaaaaay 640hp in the end and perhaps even more torque then the leaked 650….and this is STILL down roughly 50 horse to the next V, will the next V have 700 horse?! I REEEEEEEEEALLY dont think so…but at this point, i mean, i’m sorta thinking its possible that we COULD perhaps see a 700 horse V! I dont want to jump to that conclusion in my head just yet because in the end i REALLY dont think it will happen, so I’m going to undershoot it and say that going according to these leaked figures (which arent confirmed of course) that the next V might have 680 horse…..and thats if the pattern continues the 2nd time around where the CTSV has more power then the Z06.

  5. Why is 750 hp so hard to imagine?

    I like the numbers of the Zo6 cuz you don’t need to do anything to the car performance wise! Now many people will but for 90% of those buyers it will be way more car then they could ever want!

    Reply
  6. This also indicates a near 200 hp gap between the Stingray and Z06. There’s room for some middle ground. Maybe that model will be all-motor.

    Reply
  7. Elsewhere, people are already moaning and whining about the new Z06 being supercharged and not naturally aspirated.

    Why? There is the parasitic loss (mechanical and thermal), but when the car outstrips the old Z06, is that really a deal breaker?

    Reply
  8. People love to complain! They are never happy!

    Reply
  9. The current CTS-V has the supercharged 6.2 as I’m sure you’re aware and the ZO6 has the naturally aspirated 7.0. That’s why the CTS-V is up 50 hp on the ZO6. If the new CTS-V uses the same engine as the new ZO6 then I’d expect it to actually have a little less hp, maybe 585-600. Of course if I could afford a CTS-V, I’d bring it to Callaway or Lingenfelter to get those 700 horses, or maybe even 1000!

  10. Was it just not cost effective to make the ls7 stand up to 600 plus hp and still be reliable in Stock form?

    Reply
  11. The purist are not SC fans and that is where many see it as less of an engine. In the end the new car will post numbers the old never would touch. They will get over it soon enough.

    I would think they killed the 7.0 mostly for economic reasons as it was not a cheap engine to build and it did not share a lot of parts the other engines can share.

    Not sure of the numbers but they may also be able to better meet emissions and MPG with the smaller engine too.

    The next complaint will be the price on the Z06 but it was not cheap loaded up anyways so they will again get over it.

    You want to go fast how much do you want to pay.

    The limiting factor on the ZR1 replacement is that they will want to top 700 HP but factors like Reliability, Emissions and MPG all come in to play. Even in low volume they do not want to make the worst MPG of any American car or deal with warranty issues if they can just go 25 HP less.

    The last engine in the ZR1 could pass all the test up to 725 HP but they never pushed it there. Just because it can do it does not mean they will. I expect 700-725 HP in the next car. Also I expect more Carbon and less weight. They could add much more performance if they can get the weight under 3000 pounds. Less mass does more for handling, braking and acceleration than more power will. With the higher price point they could do a lot here.

    You have to keep the big picture in mind when they make choices like this as GM faces a lot more factors than web speculators do. Just because it can bolt in dose not make it pass tests, durability and pricing. GM has all the facts and we just sometimes just have to trust them on what choices they make. They generally have a better idea what is all at stake. They are the ones who have to deal with the fall out of a bad warranty choice or marketing issue.

  12. i hope its a resigned 7.0 like how the 6.2l (lt1) was….. if it is a re done 7.0 that makes 620 HP / 640 hp naturally aspirated that would be perfect, then the ZR1 could be a resigned LT1 with a supercharger to make 700 – 730 HP i could see that gm making the 7.0 a signature corvette engine

    Reply
  13. From all indications the 7.0 look dead and it really matters little as we will have more power.

    Note GM also has another name the L88 coming and it may be the engine in the ZR1 replacement.

    Reply
  14. So you want to use a larger engine to make the same amount of power just so you can have something to talk to your friends about?

    I don’t think your kind of people should be interested in these type of cars if all you want is a talking or bragging point!

    The people that want these cars want them to blow every other car out of the water at this price point!

    Reply
  15. I just hope the final power figure is around 640 hp and 675 lb-ft. Also, I hope that this will be the first Vette available with a 7-speed automated transmission, so we could see 1/4 mile times in the 10 second turf.

    Moreover, I want this Vette to cut the GT-R’s ass around the ring, while leaving Lambos, Ferraris and Porsche 911s to struggle to even compete.

    For the ZR-1, lets turbos role with the 6.2 to post 760 hp and 780 lb-ft in order to take on La Ferrari and other hyper guns, in every speed category.

  16. they still have the L-88 to use, what could that be if they aren’t using the 7.0 engine ????

  17. Are they powering that thing with a nuke? Damn thats some good numbers

  18. @Brian

    lets sum this up instead

    people like you should not be even thinking about a sports car if you could not understand the reason of HAVING A NATURALLY ASPIRATED 7.0 its not about the 7.0 its about the “NATURALLY ASPIRATED” if a engine can be valued at those numbers and be NATURALLY ASPIRATED it would mean basic tuning, stage 1 – 3 upgrades and super / turbo charging will allow for great HP improvement and let you have more options for how you want to upgrade your engine while getting more with each upgrade… it would mean viper/gtr/porsche fanboys would not have the classic “its a v8 that is forced induction thats how it got that HP”

    it could be a 4.5L and my stand would be the same.

  20. It want reliable with 505 h.p you wnat them to push it to 600?Dont you know about the valve guide issue on the ls7?

    Reply
  21. I love NA engines also but I’m smart enough to know that bringing 600 hp plus engine to the masses that is reliable and can live long enough to make it threw the warranty without any major issues is not a easy task!

    I have a 600 hp 383 in my truck! Is it reliable yes but only cuz I built it with the best parts money can buy and I take care of it!

    Most people will take care of their corvette but some won’t, they will just drive the crap out of it! It only takes a few headlines for people to think a engine is a failure!

    I want those power numbers and if having to live with SC then so be it! Beats going to the dealer on a wrecker with a hole in the side of the block!

  22. There wil be a new LS7, unless GM has decided aginst it since saying there would be! hope not!

    Can’t wait to see what GM does with camincam (Mhale) tech, … Yes Ethel, that is why they moved the water pump to the side!

    Isn’t it?

    1. “There wil be a new LS7, unless GM has decided aginst it since saying there would be!”

      No there won’t be a new LS7. The Mk2 LS block is dead and is being replaced with the Mk2 LT block, as debuting in the LT1 powered C7, and subsequent models and trims in the future.

      Thus, the LT is a complete clean sheet block sharing very little with the LS. There may be a new 7.0L N/A block with more HP and TQ, but it won’t be called LS7, it would be called LT(whatever number or letter).

  23. Tomato / Tomoto Grawdaddy, it is the displacement (427cubic inches) that I was referring to!

    1. Then you’ve missed this important part.

      “There may be a new 7.0L N/A block with more HP and TQ, but it won’t be called LS7, it would be called LT(whatever number or letter).”

      That, and nobody apart from the marketing department uses cubic inches any more, OR can claim ownership of them (427, 350, 305 = Chevy’s, 302 = Ford and so forth). 1980 was the cut off date for cubic inches.

    Well maybe they will call it the DZ 427, at least in the gen6 Z/28 since the “302 cubic inch” motor in the original Z/28 was known as the DZ 302, Or maybe DZ 7.0 or LT7 for Daddy!

    Anyone out their have one of these and would rather it be called 7.0L or LS7 convertible?

    1. Like I said, solely for marketing reasons, for the old fucks who are dying off. 10 more years, and nobody will give a damn.

      Try getting an engineer to use cubic inches to make an engine for export. Not even the yanks use them anymore; too much needless conflict when doing collaborative work with peers.

    Nobody gives a damn now it seems but you, “old daddy”, about my use of the “LS7” reference when commenting about the next “7 liter”, maybe not in 10 years though.

    You did say the new 427 (or maybe it’ll be a 454-LS7 again?) will be called whatever they want to call it
    “it would be called LT(whatever number or letter).” hence the reference “LS7”!

    By the way, a truck, old or new would be a good place for the 427! (what the 2014 Chevy Silverado Cheyenne Concept should have) and no one will be confused by acronyms what I mean by that!

    Reply
    1. The ‘7’ in LS7 is an internal RPO code reference digit, NOT a reference to the engine’s displacement.

      Surely you’re not that stupid.

      They could call a new N/A 7.0L LT block the LTC and it would still be a N/A 7.0L engine. Also, nobody said anything about trucks, and nobody cares.

      “and no one will be confused by acronyms what I mean by that”

      It’s not an acronym, it’s an RPO code. If you’re a GM fan and you don’t know what an RPO code is, then you’re not a GM fan.

      By the way, an RPO code that begins with ‘L’ denotes an engine. You can’t excuse yourself from not knowing an RPO code is by saying that you’re too dumb.

    “The ’7′ in LS7 is an internal RPO code reference digit, NOT a reference to the engine’s displacement.”

    You mean to tell me the base Corvette doesn’t have a “3” liter engine? OMG! Good thing or the L98 (there’s that pesky “RPO” code again) 98 liter would break the bank at the pump.
    Surely “you” are not that stupid, did I not mention the 454? (7.4 liter for all those dying old f_cks)! not to mention all the other 427 RPO’s.

    “It’s not an acronym, it’s an RPO code. If you’re a GM fan and you don’t know what an RPO code is, then you’re not a GM fan.”

    Since they do use their “acronyms” (see below) over and over again they damn well could call the next 427 “LS7” if they choose to, it is their “O”ption! Do you really think GM pulled the number 7 out of a hat when naming the latest 427? If they do call the next 427 (god I love that number) the “LT7” is it just coincidence? if it’s marketing then yes, it has everything to do with displacement, and your argument is moot. Who says it will be N/A (acronym), could be in the C7 (also an acronym) ZR1!

    “Acronym” an abbreviation formed from the initial components in a phrase or a word. These components may be individual letters (as in laser) or parts of a word: wiki

    But who cares,
    Has it been 10 years yet?

  31. Does anyone know why car companies went to liters for engine size?

    Reply
  32. verses what, cubic inches? No idea. Maybe c.i.’s dont translate well or period to most people and perhaps the liters do so better, who knows.

    Reply
  33. Doesn’t translate well! What’s better then the exact engine size number?
