2023 Corvette Z06 Horsepower, Torque Figures Revealed

GM Authority sources have revealed the 2023 Corvette Z06 horsepower and torque figures ahead of its official debut this afternoon.

Our eyes and ears on the ground have confirmed the 2023 Corvette Z06 horsepower output will reach 670 horsepower and 470 pound-feet of torque at launch. While this torque figure is lower than that of the C7 Corvette Z06, we must remember the new Corvette Z06 C8 utilizes a flat-plane crank, naturally aspirated DOHC 5.5L V8 LT6 engine that is of a much different design than the torque-rich Small Block V8. The LT6 engine will offer its own unique advantages, including a sky-high 8,600 rpm redline and superior drivability. This engine will also produce a very exotic-sounding exhaust note, as evidenced by GM Authority spies.

GM has already shared a photo of the C8 Corvette Z06, revealing its C8.R-inspired front fascia, larger front air intakes and revised side air intake with a black-painted “wishbone” trim element. The vehicle will also receive a wide body treatment with a more pronounced stance and flared-out wheel arches, along with wider wheels and tires – Michelin Pilot Sport 275/30R20 rubber up front and 345/25R21 at the rear.

A new center-exit quad tip exhaust setup will reside out back, joined by a revised rear fascia accommodating the widened rear arches. There will be an optional Z07 Performance Package available as well, which will include new aero features such as a larger front splitter, front aero dive planes and lightweight carbon fiber wheels shod in sticky Michelin Pilot Sport Cup 2 R rubber.

The 2023 Chevy Corvette Z06 will debut today at 12 p.m. EDT. The best place to watch the new Corvette Z06 reveal is right here on GM Authority, as we’ll host the Chevy live stream via this link and will also have all the official details on the vehicle, including photos, immediately following its unveiling.

  1. The torque number is lower because the displacement is lower. Rpm can make high hp. But it takes displacement to make torque.

          1. Interesting and completely unnecessary name calling. You were way off in the Silverado 2.7 thread and now you’re going down the same road on this one. You seem to be class act. I suppose explaining it to you with examples would be fun but I suspect you still wouldn’t get it.

            1. Way off about the 2.7 how? I think you believe I replied to a different person in that thread. See in that conversation thread how I replied in line to you and not under you? Meaning I was replying under the same person as you, once again agreeing with you. But please continue on your path of ignorance. Come on, Phil.

              1. My path of ignorance? How rich. You’re stupid all the way around I see.

                1. Haha, oh Phil, I’ve agreed with you twice and you’re still acting like a fool. Time for you to agree with me on that and move on.

                  1. Andrew baby…I’ll agree with you on the 2.7 comment. I screwed the pooch on that one. Hard to see the string properly on my phone. The name calling was pretty juvenile and unnecessary which makes you a bit of a troll. I’ll just leave it that and won’t bother with you anymore there big guy.

    2. FORD did it 1st with the Mustang Shelby GT350, 2015-20 So now it’s Chevys turn 2023-202?

      2. 2014 Shelby 680 hp 630 torque

  2. Torque will likely hit peak around 6800rpm

    1. 6300 rpm torque peak per Tadge

      Reply
  3. I’m not sure what superior drivabiklity is…hard to believe it will he better than an lt…sounds like marketing. Another disservice associated with this articles claim of low torque also revolves around the fact that this engine actually has a higher torque/cu in rating than the lt engine.. the overall number is just limited by displacement.

  4. Wow, More HP and less torque than I expected, must make peak HP around 8200 rpm I was expecting 7800

    Reply
    1. Hopefully it lives up to the hype. It’s set up to make a big statement for Corvette globally

      Reply
    2. New information from Dustin, the assistant chief engineer on the LT6 , It weighs only 1 kg more than the LT2 , and makes peak HP at 8400rpm, I was close…

  5. From the earlier report on here, you have to be out of your mind to think a N/A 5.5L FPC is going to have over 500ft-lbs of torque.

    Reply
  6. I think it is correct that a Flat crank engine will turn up to Max RPM faster than a counterbalanced crank due to being much lighter. Downside is a harmonic vibration from the lack of balance that can be mostly dealt with using a balance shaft and placement of engine mounts. Have driven a few flat crank cars and they turn up RPM insanely..

  7. 670Horsepower are 680PS (DIN norm) and the 623Nm are more than 626Nm (DIN norm) and these are great values for the LT6 V8 with 5.5 liters. Above all, the higher speeds are good for a slightly less heavily loaded drive train and the revving (response) is therefore terrific. I was aware months ago that the LT6 5.5 liter Supwer V8 will and must have these high PS / NM values, because the competition never sleeps. We know that in the future Ferrari, Porsche and Lamborghini will only build turbo engines with PHEV support, the ZO6 Corvette will also be and remain the lightest series super sports car of all time. Thanks to the Chevrolet Corvette Team.

  8. GM Authority: Is there any way to mute a particular participant?

  9. Would have expected something better than 2.6 sec 0 – 60 with all the hype about how fast the LT6 spins up. Oh well, I guess it’s just numbers

    Reply
    1. That’s about the current limit for RWD cars, so pretty, pretty, pretty good. I wouldn’t be surprised if the AWD E-Ray matches or beats it in 0-60 though.

  10. The engines won’t last. Not at those revs. Better get extended warranty.

  11. I absolutely love the new ZO6 but I would be lying if I said more TQ wouldn’t have been better.
