What everyone missed about the 2023 Corvette ZO6 LT6 reveal
Вставка
- Опубліковано 4 лис 2021
- The LT6 is the newest engine in GM's lineup. Even though it's called an LT6, it shares nothing with it's "LT" family. There's a lot to learn and feel free to pause the video to view any details that I left on frame because I don't want to bore to death with technical numbers and calculations. What a refreshing site to see at a time when everything is going electric or turbos. At this point in time, this is one is going in my all time best list.

As long as GM is producing such a new world beater engine... they can call whatever they please!
V shapy thingy fucking ferraris.
It's the same as anyone they gave up low end tq for high end hp. Also they are using a expensive low production engine not based on other stuff they produce. But hey gm already said they lose money on each c8 that's why they are so limited in production. But they miss the mark for consumers. What would you rather have a 850hp 850tq engine that makes power all over or a high strung n/a motor that also vibrates much much more and sucks to drive anywhere besides a race track and still with all the drawbacks gets killed by a car that's available and cost 50% less. Boost is God and when people are making 1500hp and 950ft lbs out of 2.0 motors well we know that the c8 already had heat issues adding a turbo was probably not a option because with 5psi the stock base c8 would kill this 50k more expensive car
@@mddunlap03No one knows what your comment means. Maybe you could tell your Mom and then let her make your comment. That way people will know what you mean.
@@dbx1233 I understood him just fine and I think he has a good point.
@@bobthbldr3 Well, then I guess that settles it.
I figured it was named LT-6 because it's the spiritual successor to the often forgotten 32 valve DOHC LT-5 from the C4 Zr1.
or maybe Louis chevrolet
most people have never heard of the LT 5 made by mercruiser. 32 valve dual over head cam Chevrolet V8. I want 3 of them!
Yup...and it was designed by Lotus, which GM owned at the time! Mercury Marine had to build it as GM had no factory abilities that could do so. That ZR1 PowerPlant is still amazing today.
@@45auto17 If you like that you gotta check out the Doug Rippie bllack Widow versions of the engine with up to 575hp. It's a convoluted story and he's not the only guy involved obviously, but it's a great read.
They should have named C7 ZR1 engine LT6 and C8 ZO6 engine LT5, it has more in common with the C4 LT5
The photos of flat-plane and cross-plane crankshafts are wrong. The top photo is a flat-plane, not a cross-plane. The bottom photo appears to be a UDUD flat-plane crankshaft from a Ford Voodoo engine.
Awesome to see how far the Corvette has come. GM has finally done what Zora wished for. This was the future he visioned and it’s here !!
It is very cool but also a bit more than just bitter-sweet.. Very cool to see it achieved yet also annoying in how it's coming just as everything like this is about to end. It's the KILLER mid-engine ICE powered car that will share a show-room at chevy dealers with EV models that signal it's demise just as it was getting started.
Exactly I remember reading about a mid engine corvette when I was 16 a long time ago
@@dougweaver1773 and to the other replies: I completely get exactly what is being said. It very sad when concepts from the most brilliant minds get squished and thrown out. I’ve always heard corvette owners were super particular with not changing many things in there beloved cars. Was GM scared of ruining the corvette due to this or just exec. members never understanding how revolutionary this actually was. Could they have built it for the costs of FR ?
But I agreed they shouldn’t be brought out against EV models on the show room floor. Even when the 90 ZR1 came out it was too much $$$ for “corvette owners” to take. Even thou that was one serious car. Nothing could keep with that. Anyway great comment’s 🤟🏼
Hey, you guys don't think this engine would get worn badly in 3-5 years, do you? ... come to think of it, it's in a tuned version by factory - Factory tuned engine.
The new ZO6 is absolutely nasty. I cannot recall a Supercar engine sounding this good since the Toyota LFA or Ferrari 458 which says a lot. I could only imagine how crazy the new C8 ZR1 is going to be. It’ll probably end up being an 800 plus Horse Power twin Turbo monster.
Check out the GMA T.50 if you like good sounding supercar engines. The T.50 is the successor to the McLaren F1.
It sounds like it was kicked in the nuts and these motors are gonna be junk on the street.
@@Outtacontrol304 I was always told: "Horsepower sells cars, but torque wins races"
@@Outtacontrol304 Says who? You? LOL.
@@barrythehatchet1380 Not power to weight ratio? I'd say many elements count, even active suspension around corners can be heads and shoulders against others.
In the 90s GM would tell European automakers that pushrod technology had compact power. GM needed an engine that allowed a dropping hoodline, so drivers could see the road. Mid engine allows a dropping hoodline too, and also space for DOHC architecture.
Very good point. Regarding WWII aero engines, the systems engineers (not known as that at the time) dealt with 'installed drag'. LC engines yielded a sleek nose, but needed heat transfer radiators somewhere.
(The P-51 found the best compromise)
“Wow. What a dilemma” indeed! I will get a C8 and it will be my first GM product. I’ve had 5,0 and 4.6 Mustangs, 6.1 Hemi SRT8 Charger, and the C8 has me BowTie lustful. Love to see USA engineers get things right and make masterpieces.
That is what happens when you get the Bean Cuonters out and put the Engineers in!
You know it's good when it converts heavy Ford cultists.
Too bad dodge and ford are not American made cars
@@tinytim71301 sick bro!!
@@abel4776 liking ford over Chevrolet doesn't make us a cult. Some of us like them all, just have a preference for not having to work on something every day. I will never EVER EVER own another Chrysler product though. Jesus they are shit piles
Chevy ftw, always KILLING the competition without even trying!
you fan girls are insufferable
@@Fee.1 fan? All American brands suck but they are the best of the three.

@@Fee.1 shut up ford boy only reason your here is because your cars not running….
BBBWAAAAAAAHAHAHHAHAHA
oh. You were serious
What incredible content! 🔥 just found your channel cuz of this video. Keep the c8 vids comin!!
Fantastic job explaining,bet the research took a minute,explaining it all with proper graphics puts this video at the top,very nice job,my first time viewing ur content...spaceship was dope.
I remember ZR1 in early 90s' 405hp. Dual overhead cams 32 valve. Bravo! Chevy for getting out of stone age push rod motors!
But give Chevy credit for amazing performance in push rod engines, which aren't going away .. still the best V8 performance bang for the buck.
ZR-1
@@KrustyKlown l agree, push rods and 2 valves per cylinder cause tremendous stress on valve train at high r.p.m use. Overhead cam 4 valve design is the way to go! 2022 Vette redlines around 9,500!
NHRA Top Fuel and Funny Car class. The quickest ICE cars in the world. Are all pushrod, 2 valve per cylinder. The architecture of the engine goes back to the 1950’s Chrysler Big Block V8.
@@frank.l181 yes, but with 2 valves, you can't breathe that high anyway, so you couldn't use a "high RPM" valvetrain anyway.
Basically 2 designs approaches:
1) High RPM, lower torque (not as much stroke to keep piston velocities manageable) - over square - larger, heavier engine (DOHC takes up lot of space)
2) Lower RPM more torque under-square (more stroke) smaller overall foot print.
Neither of these are a "perfect" solution, each has a trade off.
Just like flat plane vs cross plane:
Flat-plane - lighter, faster revving, more power (due to better exhaust savaging) - perfect 1st order balance, CANNOT be balanced on 2nd-order vibrations.
Cross-plane - Heavier (counter weights), lower revving (can be used with longer stoke for more torque) - perfect 1st order AND 2nd-order balance.
Everything is a trade off.
wow, nicely done video;
If the mill is engineered as well as it looks, I believe this will be a game-changer
Great video with engine cutaways explaining the intake plenum and velocity Stacks best I've seen on the web so far
Thank you for watching.
First one of your videos I have seen. Great stuff man! You definitely got a new subscriber!🤙🏼
Great content very didactic, and we all looking forward to take a closer look to that beast!
Very nice video, well research and presented, nice job, I feel smarter now!!
Excellent content very well thought out! Love it 👌
excellent coverage..the most in depth of all ive listenned 2...n/ive heard alot..thancs.
Wow...the sound is incredible... can wait to hear it in person...
The aftermarket will have this motor screaming to over 9k rpm. Thats gonna sound heavenly
Very well put together video! Appreciate all the info!
Thanks!
This is an awesome video. Thank you. In the Z06 list. Fairly low so learning as we speak
Great video content. Thanks for putting it together.
Great video! I learned a lot about this amazing engine. If it's everything GM states it'll be one amazing car! I am looking forward to it being put thru it's paces.
Bro this is the best engine break-down video I’ve ever seen! Nice one
Well Done, you definately did it justice. What a rocket ship.
Very good information about the complex engine history.
What a great well done video!!! KUDOS
Very interesting and informative. Thank you.
Great highlights
Wow! Thank you for talking about all these things! 🙂👍
You're welcome!
Well made video .. very informative!!!
Really good informative video. very technical going to have to rewind a few times 🙄 as it went a little fast for me 😁 as in comparison between engineering/ platform. Differences generational similarities,, and advancements in technology.. thank you for no music background..!
A chevy engineer said they gave the Z06 a shorter gear ratio in one of the videos I watched. It is gonna pull hard that is for sure. My father got a 2022 Z51 and that this already is nuts so I cannot imagine this new Z06.
Good to see you!!! New corvette Z06 is pretty nice
Ford Pantera back in 1971 built a mid engined car with a Ford 427 cubic inch engine.... now that was a beast....😁
That car had a 351 Cleveland engine I believe not a 427 and Pantera was not Ford they just used a Ford engine.
Thank you awesome information
Thank you for the video sir
Cant wait to see one of these make it's way to a motorcycle or something. That's gonna be stupid awesome!
Very interesting and more about the engine than I had seen before. Interesting that they use a flat plain crank right after Ford drops theirs. Finger cam followers; I hope they work out better than they did in Chevy's 2003 Indy engine because I had heard that was the reason that went flop! (They started using an engine they bought from Cosworth mid season in 2003). It was also frustrating that very little of the accessory end of the engine was shown. It would have been nice to have seen how the cam drive and other accessory were arranged compared to the LT-2. Belt or chain, turning four cams takes much more than turning one and gets messy fast if not given proper attention!
This engine is based on C8.R race car, which race in ISMA racing series. Which race endurance races. The flat plane crank has proven to be reliable and powered the C8.R to back to back championships.
This is a dope channel. Just checked out some of your videos. Thinking about subscribing soon
Thank you for watching.
Awesome video!
Best video on UA-cam! Beats even the biggest channels! This was super informative 🏁👍!!
Glad you enjoyed it!
Good video! Nicely done! Made me a subscriber.
Thank you for watching.
Great video! I love the 3D exploding animations of the various internals. Right at the 5 minute mark, you show an incorrect pic of the flat plane crank. You show the one for a Ford Voodoo engine. On the Corvette, and Ferraris, the two center pistons rise and fall together, not so on the Voodoo. (The cross plane crank illustration looks off too). The illustration just after that clearly shows the two center pistons rise and fall in unison. The voodoo engine sound with that different crank configuration, while high revving, is more like a traditional cross plane v8.
Glad I wasn't the only one to catch the odd Voodoo crank.
LT-1 was used in the 70s as well. It was a hot 350 small block. They also had a LT Type.
By far the best explanation yet
Nice work Gary!
Dude u are awesome. I like how u make all that complicated info come across only wish I understood all instead of some of it 🙃.
Great video! I sure would like too know how this all solid valvetrain requires no valve lash for the life of it. Unless the life is very short!
Will be interesting to hear the stories of owners once they get some miles on them. That being said, it does look like a lot of solid
engineering to bring the engine to reality and it's a very good looking engine at that.
You do know the valves can be adjusted by changing shims?
@@REDMAN298 yes actually I do know that the valves are shimmed by hand as the engine is built and they claim that they never need adjustment again.
Each valve shim is computer measured and cut to get the exact size needed, according to Tadge Juechter.
Sorry for the typo - I meant LT6
@@benn454 And? You do realize valves move as the engine wears? Usually the valve seat sinks somehow, the "computer measured" valve clearance is no more and the exhaust valve hangs open. Run it like that for long and it's pretty damn expensive to repair.
Most everything is hydraulic any longer and most people have no idea what's meant by adjusting the valves. That's how you can get marketing to say "solid lifter, never needs adjustment!" and people don't laugh them out of the room.
I bet it's like lawnmowers that never need oil changes. There's so much else wrong with the thing by the time it needs valve lash adjusted that the exorbitant price of doing so due to the engine location means nobody will ever do so. Just go buy a new one...
I love the sonic boom exhaust sound that the C8 Z06 has. It's one of those few v8 engines that sound better than most V10s and V12s.
I'm looking forward to see this lt6 on the ultima RS
Great information
Great Video, very informative, Thank you
You're welcome.
Great video. Only thing I would add is about the dual valve springs. The real reason for using a dual spring is to prevent any potential valve float through harmonics.
the Z06 is one sweet ride, cant wait to see it
Good informative vid.
Incredible! I am waiting on one, as we speak!
John:
What area are you currently living? I recognize your last name.
I'm affiliated with a lot of people on the East Coast. New York ,Brooklyn, Staten Island, Howard Beach, New Jersey ,Florida.
Perhaps I can help you with the price if I know your family.
I can’t wait to see it work on a long track, I doubt one is in the books for us immediately but I can see how and why Gm did what they did, remember this engine it still in its infancy the potential is far beyond anything built today.
Nice looking car love the manifold
What an amazing machine.
Why doesn't GM use an incremental naming convention? LT1, LT2, LT2..LT9, etc...
It does! But GM also likes to reuse it as well, hence the confusion.
Good video, very informative!
Thank you for watching.
Incredible engine!
Wow. This sounds really good.
Best Video pertaining to C8 ZO6 Engine HANDS DOWN , Thank You
You're welcome
Most powerful N/A V8 period, not just flatplane!
I truly believe most of this has been in the works for a while. Most recently the black wing 4.2l v8 found on the 18-20 Cadillac v
Finally something new worth buying
5:44 - You bet! The DFV on my vintage F-1 shook apart anything that wasn't shock-mounted.
First time Chevy has raised my eyebrows in a while. Bout time they let one breathe !! Sweet !!
Hand built/ production ?? Is it attainable. ?? We’ll see.
I forget what they call them but when they make the header tubes all exactly the same length and volume and how good it sounds on different Chevy V8's! Having something like that made for this engine would be mental I bet!!!
Nice video. If I had the money, I'd buy one and put it in storage. This has to be the last ICE Corvette. Very nice
FYI: Flat plane cranks definitely use counterweights
Great video accept for when explaining the flat plane crankshaft. You use a picture of the voodoo crankshaft that, while being a flat plane, is completely unique to itself and not a good representation of the typical rod journal placement of a flat plane crank.
I noticed that too! You beat me to the comments section! :-)
True story
I saw that too! Right at the 5 minute mark. Even the cross plane crank illustration looks off. The illustration just after that clearly shows the two center pistons rise and fall in unison. The voodoo engine sound with that different crank configuration, while high revving, is more like a traditional cross plane v8.
@@timothycravens223 and sound is the only reason Ford used that crank configuration.
Except, not accept. All the boys made the basketball team except Marvin. Amazon will not accept my return.
Thanks for the great HQ vid. I wonder how the fuel is mixed up efficiently at high rpm and high load hence there is no time. This is a known problem, that’s why some engines are built with combined injection systems to join advantages of both worlds. Cosworth still uses port injection in their V12 engines.
Maybe the ability to "build pressure" via the velocity stacks helps.
@GT Content Porsche had velocity stacks in the 996 I believe it was. They were vacume adjustable.
Great Video - Thanks! I’m #530 at my dealer for the Z06!!
Wow! One of the best illustrations I've seen, Chevy should hire you as their spokesman. :) Thank you for this Video.😊
Glad you liked it!
Chevy knocked it out of the park with this one! And if they make a AWD supercharged one it will be insane! Let's just hope they do it!
It’s already being done. The next version is supposed to be a all wheel drive with a electric motor in the front of the vehicle for the front wheels and I believe it’s called the eveo. Not sure how it is spelled. The next thing is going to be the Zoro all wheel drive and don’t know yet if it’s twin turbos or not but it’s rumored that it’s going to have around 1000 hp. Just what I’ve heard from Chevrolet dealership as a Technician. Jmo
I would love to install this engine in my 97 ws6!
Great video, rich of information
Thank you for watching.
You forgot to mention the LT5 from C4 ZR1
Anyone else noticed that when he talked about the crankshafts, he showed a normal flat plane crank without counterweights as an example what crank it does NOT have, and showed a picture of a technicly flat plane crank with abnormal design, that does require counterweights as clearly seen as an example for what crankshaft design it has, even though it has the normal crankshaft design. He even said the crankshaft in the LT6 does not have counterweights. The flat plane crank that he said it has but does not is actually a flat plane crank from a V8 by Ford, in which performance was sacrificed for sound.
yep was about to comment this
very well done video !
You're welcome.
LT6 is the next number after LT5 (the last DOHC) so it isn't really confusing. Of course it just an option code so doesn't really mean anything.
One little detail - the flat plane crank showed is that of the GT350 and a very odd design because of their sound goals. Traditionally, and I'm the LT6, the flat plane v8 crank is just like that of an I4 with an up-down-down-up configuration.
The pictures at 5:04 are incorrect. I think the upper crankshaft is actually a typical flat plane crankshaft, whereas the bottom picture looks like the crank in the Ford "Voodoo" engine.
Yep, at 5:04. Two different versions of a flat plane crank. I know it’s a confusing concept and that’s why we aren’t all engineers.
This thing is going to be bananas under boost.
very amazing character-body design. sf90, c8 z06, nsx 2nd-gen 😱all of them
The trans is by far my number one concern, not that I didn't already consider that when I bought my 17 GS manual C7 as the C8 was being introduced. That purchase gave me a chance to prepare for a future automatic, but with design flaws already determined in this 1st generation DCT I can only hope that a series II or III is underdevelopment and will show greater promise
you predicted the future
Both of the crankshafts in the pictures are flatplane. It's just that the asymmetric one is from the GT350 mustang
4:56 isn't that Ford's Voodoo engine crankshaft?
GM MAQUINA PODEROSISSIMA DE ALTISSIMO PERFORMANCE, DESEMPENHO, MUITISSIMAS QUALIDADES SUPERIORSISSIMAS, TECNOLOGIAS AVANÇADISSIMAS, RESISTENTISSIMO, LUXUOSISSIMO, CONFORTAVEL E ETCS
I think this is supposed to supersede the original 1990-1995 LT5 found in the original ZR-1.
It was also a DOHC V8, however that was a regular cross plane crank. But they’re both marvels of their time.
I have a feeling the ZR1 will be a hybrid assist with this engine or twin turbo version of this engine
Dual valve springs aren’t for backup. It’s to keep control of the valve during harmonic events.
Good info
Thank you for watching.
The LT 6 has a has thicker cylinder walls with more space between each cylinder! It also has an insanely short stroke. n/a built is more of a feasible route this time around for a lot of power gains vs just throwing a supercharger, which is more complicated now or a turbo system. ;)
That picture of the flat plane crank you shower clearly had counter weights
8:00 gave me the feels
At 5:02 picture of the cross plane vs flat plane crankshafts. They are both flat plane. One is from LT6 and another from Shelby GT350.
The image of the flat plane crankshaft you used is from the 5.2 Voodoo from Ford. That was the only car to use that flat plane crankshaft design. Ferraris and the LT6 use a different design.
