General Motors just dropped a new teaser video for the upcoming 2023 Corvette Z06. The new go-faster variant of the mid-engine Chevrolet Corvette will debut this fall.
The new teaser video is just 24 seconds long, but features an enticing soundtrack, giving us an earful of the engine in the 2023 Corvette Z06 as it shifts through the gears at full throttle. The accompanying imagery plays between the race track and a county two-lane road.
“The street will never sound the same,” reads the overlaid text.
That soaring, exotic-sounding engine note comes from the 2023 Corvette Z06’s new naturally aspirated 5.5L V8 LT6 gasoline engine, which features a 32-valve DOHC design and a flat-plane crank. Redline should be north of 8,000 rpm. Based on the same V8 found in the C8.R racecar, the LT6 in the 2023 Corvette Z06 is expected to produce around 600 horsepower and between 480 pound-feet and 550 pound-feet of torque, with an eight-speed automatic transmission sending it all rearwards.
To complement the impressive engine specs, the 2023 Corvette Z06 will also feature unique styling, as GM Authority has covered previously. The new look will include a massive rear wing offered as part of the optional Z07 performance package, and new lightweight carbon fiber wheels. The latest go-faster Vette will roll on wider rubber too, with 275/30ZR20 tires in front and 345/25ZR21 tires in the rear, courtesy of Michelin’s Pilot Sport Cup 2R compound.
Notably, the 2023 Corvette Z06 also includes a new Z06 badge, as was leaked online back in May. The new logo includes squared lettering, rounded edges, and italicized script, and can be seen in the latest teaser video embedded below.
All told, the 2023 Corvette Z06 is shaping up to be an exciting new addition to the latest C8 Corvette lineup, and given GM is benchmarking it against heavy-hitters like the Ferrari 458 Italia and Porsche 911 GT2 RS, it should have some pretty impressive performance chops.

Screaming like a banshee on fire!
Honestly this is great, but all I can think is this engine with a cross plane going into a Silverado/Tahoe SS
Never happen, trucks get regular LT variants, This engine is Corvette only.
Won’t happen as it’s a high rever, not a torquer. It makes its power past 5000rpm, and torque peaks higher. That’s close to most trucks deadline. More than likely, if GM will update the V8’s, they’ll use the 6.6 L8T as the bones and retune for higher power or add the high valve lift in a variable valve lift setup like the 2.7 turbo. Both options increase the torque from 2000-4000 rpm. I would like to say though the new vette 6.2 makes 470 tq with a moderate cam height, imagine what it could do with a variable cam with high lift? Moderate lift cams are used because of idle quality. You don’t want it sounding like a Harley, if anyone is wondering why cars use low and moderate lift. I think we could see a 6.2 with 490tq, similar power with variable valve lift, as well as improved economy while idling and cruising quieter than an a Tesla.
Jake, he said cross-plane, not flat-plane. A cross-plane engine would have the torque a flat-plane lacks.
Bingo
GM is not going to put a smaller N/A engine in the trucks… Also this 5.5L engine has mostly all exotic parts, which are expensive. An LT4 variant is cheaper to build, and much more powerful. If there is a Tahoe SS, it will share powertrain with the Escalade V, will be a supercharged 6.2 L
GM had thought about doing a Camaro Z28 with this Corvette engine, but that has been canceled.
Emissions.
More like Camaro’s aren’t selling, but you can think what you want…
Not at 5.5 liters. It’s all about air. It would have a little more torque than the 5.3, but not as much as the 6.2 down low, nor even mid range. Look at the ford coyote. It’s power is all up high, but down low, the 5.3 is dominate. Mid range the coyote and 5.3 are equal, but the coyote is a more expensive engine. The 5.5 exists solely because racing restrictions are cranking down on America big blocks winning everything leaving Porsche and Ferrari in the dust, so the solution is maximum displacement for most race regulations (5.5L) and rev it out. The 5.5 wouldn’t feel any different that the 5.3 until 3000 rpm, and wouldn’t feel better to the 6.2 till 5000. You need a engine that superior at cruising, towing and high power for luxury truck, the 5.5 only excels at one of those points. Keep in mind the 6.2 in the current Corvette is “too large” for certain races.
Keep in mind as well, the Z06 shouldn’t be having a flat plane DOHC. A true Corvette Z06 needs an LT7, a 5th gen small block of the fabulous LS7. That is the nirvana engine we all deserve. It would be perfect for a ZR2 as well, but many races cap their displacement, thus 5.5L size.
No way, that LS7 was great at the time, but it was not the most pleasant cruising around town, struggled with low end torque for such a large displacement, and had poor emissions. Corvette is evolving into a high tech supercar, and the DOHC high revving engine is the next logical step in that evolution. It will embarrass an LS7 on the track.
This the need to have an LT varient. The anomaly of the LT1 was it maintained 90% of it torque along 90% of it’s RPM range. That was more than the LS’s or any ford engine. Given almost 2 decades the LS7 is still a potent engine. Imagine what all the new tech and tuning would do.
The problem for the LS7, compared to LT1, is the camshaft. The LS7 had a pretty big cam, with a fair amount of valve overlap, which makes meeting current emissions tough, and also takes away low end torque, so drivability is compromised. Also increasing the hp on the LS7, likely required more RPM, and with its long stroke, was already near the limits of piston speed for a production engine. Race engines can operate with much higher piston speed, but they do not have to last 100K miles under warranty. This is why you see the 5.5L with a much shorter stroke and more RPM, to make more HP. GM is giving enthusiasts a gift with this Z06, this engine will be a legend like the Chevy 302, nobody will remember the LS7 in another 10 years, unless you are talking about the 454 LS7 from the late 60’s.
How can any vehicle with an ICE engine, w/ the exception of Hybrid technology at a cruising speed typically below 40mph, be quieter than a Tesla at idle? Or any other electric vehicle. Are you serious?
Listen to literally any electric car or hybrid…. “Wwwwwwrrr” is the sound they make with the electric whine of their motors. I’ve driven an opel Adam the 1 time I toured Europe, and that thing was quieter than every hybrid I’ve ever driven on work trips or Tesla that has passed me by. Even with the windows down. It’s called sound tuning. You tune the intake, and the exhaust. With dynamic skip fire and low valve lift, at idle, there will be 2 cylinders sucking almost no air. There will be nothing to make any sound, especially not eltric motors “wwwwwrrring”
Electric cars are far quieter in general, the wrrr sound you mention does not move a decibel meter the same as the pulses of a piston engine sound. You can tune piston engines quieter, but not like an EV in general.
Then the EV makes the same wrrr, and blows you away in a race
Name 1 race that EV’s win… Just 1. Last I saw a YouTuber had to give the model S a headstart for it to beat the new vette in the 1/4.
Yeah what do explain the Tesla plaid beating out most supercar even the McLaren p1. You fool.
Tesla got busted for fudging their numbers. They did that on a studded test track, and they Also run a 15 minute precool cycle to chill their components before. Imagine what I could do with a Camaro with that luxury. When Motortrends tried to replicate their claims, Tesla pulled the trial event when Motortrend said they were taking it to a non studded race track. So it really doesn’t pull that fast. Also the Camaro SS beats out Teslas numburgrind tuned model 3 that was supposed to prove EV’s can race. Not the ZL1, not the vette, the 40k SS. So, once again, with the new vette beating the model S in ludicrous mode, what is Tesla winning again?????????????? Like anything???????
Drag times did 2.1 seconds 0-60 and quarter mile of 9.3 second, it also smoked a Lamborghini aventador sv easily, trying to fool me huh fool.
And I’ve seen a 93 Camaro pull a sub 7. The point is that can it do that every day when on the street a Lamborghini pulls up along side it? Well never know cause when Motortrend went to verify those numbers, Tesla pulled the event when Motortrend wanted to do it mid afternoon on a normal track, not mid morning on a studded track like Tesla wanted it to be. Why? Beacause Telsas numbers aren’t real!!!! Telsa creates beyond ideal conditions, runs hundred of runs, takes the best number and rounds down! That honestly is illegal and is called false advertising
Speaking of which, part of the reason EV’s suck is because they are not held to the same SAE standards as ICE cars are. The 0-60 of the vette is what your standard driver can do if he puts on launch control and let’s the machine burn. Anyone can do it with a little practice. On a studded track with a little wheel chirp, and traction control off, low and sub 2’s are easy.
Same with EV ramd and power. all these EV’s with supposedly 500-600-800 HP? They have the se output as the Chevy 6.2 naturally aspirated. Why? Cause it’s 460 HP is SAE rated, meaning at 1000 ft altitude, after running the engine till it’s hot and spark timing is retarded and these ratings are minimum lawyer proof values, so 90% of engines exceed that value. Your vette at sea level right after cruising around is putting out 600 horses, and that Tesla after cruising around has dropped to 500 as the batteries warm up, so there you have who wins the pull up along side and see who wins race.
Ditto with the range. They advertise in ideal conditions. You hot traffic or curving roads, by by 10-20%. It’s amazing the BS you can spout when your cool.
What do you explain the tesla model x suv beating an audi r8 plus in the grand tour when jermey clarkson is behind the wheel. Electric cars are beating gas cars in every performance aspect except the top speed.
When did Tesla get busted fudging numbers? link? What is a studded track? You mean they put “track bite” down? Track Bite is used on most drag strips to eliminate wheel spin, but the Model S plaid on a completely unprepared surface is still faster to 150 mph than any production car GM has ever built… Ever!!! And buddy, its not even close… Plaid is darn impressive, it almost hurts to accelerate that hard.
I do not like everything Tesla, and Tesla range is optimistic at best, but in testing under EPA parameters they can hit that range, and have been tested. Steven, go drive a Tesla for a week though, it will open your closed mind quickly. Tesla’s EV tech is amazing, and anybody who says otherwise should have their credibility in cars deducted a point.
BTW Steven, the track is called Nurburgring, and the Camaro is called the ZL1 1LE, which is basically track prepped Camaro from the factory. But that Camaro is uncomfortable, rough riding, noisy, and a gas guzzler, the Tesla Plaid is a family sedan, that is roomy, comfortable, ultra quiet, has amazing tech, and will beat that Camaro on most tracks (Laguna Seca for sure as Plaid already set the production car record), and at the drag strip the Camaro is not even in the Plaid’s class. The Plaid can finish the drag race and go park before the Camaro makes it down the track. I think when Tesla runs the Plaid on the Nurburgring you might be surprised, it may or may not beat the time of the ZL1 1LE, but it will be the fastest production Sedan ever tested on the track.

Read it and weep.
And NO. Is the SS, not the ZL1 and definitely not the ZL1 1LE that beat Teslas highly custom track car on the nurburgring. The ZL11LE will beat all EVS on the nurburgring for the next decade it’s such a good track car. It largely goes back to that SAE engine standards I was talking about. If a ZL1 and a model S pull up to a stop sign, the still largely cool LT4 actually is putting out about 750HP, and the moddle S plaid without it’s cooling cycle is putting out 700hp in auch heavier car. No contest. After a track run, ZL1, it’s rated 650, the model S plaid, 500-600. That precool cycle with the model S is pretty important. But Musk’s biggest fear is that the SAE will standardize ratings for consumer protection. It’s like how many of these EV’s are rate 100+ MPGe, which is a lie. MPGe starts calculating at the battery, not with charging losses, line losses transformer looses and the fact that their plugged into a gas turbine generator operating at 60% efficiency. Just take that MPGe, and divide it by 2 for your carbon footprint. Add to that the fact that eltricity is more expensive.
Tesla plaid can go 60-130mph in 4.1 seconds which is faster than a McLaren 765lt.
These Tesla haters are just missing the boat, they really should go drive one, so they know what they are talking about.
I can’t afford a Tesla but I like them alot. It’s the smug, urban, effete, out of touch with common man, beta males who drive them I’m really not that fond of. Tesla themselves are terrific.
In terms of pass-by noise, at above 45 MPH, tire noise completely dominates gas powertrain noise. At 30-40, powertrain noise is a relatively minor contributor. Thus, any comparably sized (unmodified) vehicle will have the same noise as a Tesla at highway speeds.
Just stand by the interstate. Engines don’t make the high-pitched constant brrrr you hear.
That and we had the tech to keep motors whisper quiet for decades
But wrroom wrroom! Everyone wants these things to sound like a Ferrari or Shelby. Engine noise it purposly exaggerated for pleasure purposes. Example? My daily driver is a Pontiac 4 banger. The firewall has no insulation On purpose so I can hear the motors every little sound coming out the manifold 2″ away from the firewall. It’s terrible on heat transfer.
Wow, it’s real… That is such an awesome sound…
If that doesn’t get your heart going you need to get your pulse checked!
Cannot wait to see what GM has in store for us with the upcoming ZO6
It should be an awesome car, only partial negative is its will be a bit heavier than optimal (I assume + or – 3500 lbs). You would love to the see the car be <3200lb, but that going to be tough to do at the price range they are going for.
You can say what you like about DOHC engines in trucks but most mfgs are goin* to them for emissions and GM already is doing a DOHC 4.
But I do expect GM will not go big much more as no one really is as large displacement in half tons pay a big penalty in fuel and emissions.
The Corvette engine could find its way to a Camaro at some point. GM need more volume though the Camaro is not much help.
The flat plane crank is only for sound. Tadge made it clear a while back if they can solve the vibration issues they would go with it for the exotic sound. He made it clear in this case it added no real performance advantage.
All the insane cars have been restricted in the past as they try to even the power, Most times the Vette has intake restrictions that cut the power. They moved to smaller displacement. But again in the street motor it will help on emissions.
GM has the emissions figured out with small blocks. Direct injection and skip fire and hopefully variable lift soon makes the small block cleaner than most DOHC V8. Emissions isn’t the problem. It’s the displacement limit on race engines, and the fact that C7 Z06’s had overheating issues. As the Z06 is the race edition of the vette, that meant that this engine was going to be a V8 displacing below 6L, naturally aspirated for heat reduction and needed at least 600HP. From there engineers had to get that power with high revs, thus a DOHC, and a flat plane crank. That’s why this engine is what it is. We know it will get turbos in the rediculous ZL1 and Zora trims that are rumored as those won’t be optimized for racing and will be less concerned with heat for short drag pulls at max output.
Yes but the regulations will get tougher soon and they are out of tricks.
Never said the Corvette engine would be in the truck.
Actually the heat issues will be greater in this car. There is less air in the engine compartment. Also they are adding turbochargers. I own a mid engine now. Yes they have air flow but not like you do with air from up front.
The ZR issue is tight engine compartment and super chargers do get warm. Compressed air get hot. Hence intercoolers.
Well, the hippies are currently out of tricks. Doesn’t most new engines spit out less PPM smog than they take in? Today’s engines are so darn clean it isn’t funny. Last thing I’ve seen the anti oil people push is mandatory EV sales because they can’t make ICE emissions any cleaner. Same with desiels. New tech makes current desiels supper clean. cummins cylinder deactivation tech will eliminate regen cycles and makes DEF consumption almost non existent. That will bring cost of desiels back down too.
Donavan is correct, putting a hight revving v8 in a truck won’t happen, a truck need lots of torque to move that’s part of the reason the hummer ev went electric. And it would cost gm a lot which they spent it all on future ev.
I like the regular zo6 body better, just my opinion. The new vett style is over-rated with bulky rear view mirrors, wanna be Ferrari. 🎯🤭😂
Wonder what the stick would sound like
Sounds a little bit like my string trimmer.
