CORRECTION: at 1:30, I got displacement mixed up with number of cylinders. The Corvette has 10 liters, while the Viper has 10 cylinders. I made a goof when I said, "The Corvette has almost 10 liters, the same displacement as the Viper." Sorry about that!

Dodge, lets make a car everyone hears about and wants... Chevrolet: Lets make a response but keep it hidden.

Sounds like its running on 9 cylinders... won't idle, sounds like it could use an experienced driver and a clutch adjustment.

I've heard more than one V/12, and that one has a nasty miss fire.

Am I the only one thinking the driver REALLY needs to get off the clutch?

If this would have made it in production the automotive industry's response would have been awesome.

This is one Corvette that even I have never heard of.

The shot of the ZR-12 and the RT/10 in red side by side with the hoods open just took me back to being a kid, they both look as tasty and beautiful and amazing as they did when I saw them for the first time nearly 30 years ago ! Thanks for that👍

This guy gets paid to burn up a clutch, drive through a parking lot and do about 15mph...wow I'm impressed. Also sounded like it was only running on 9 cylinders.

"Sounds like nothing else!" Refuses to rev above 1100rpm, or drive above 15mph.

You're doing a tremendous service to the automotive Enthusiast Community by posting videos of these extremely rare and obscure cars. Keep up the great work!

Holy shit the way that thing growls. You’d never expect to hear that in any factory street car. A V12 that growls the way a V8 does.

You can tell that thing has been sitting forever the valve guides are already worn as it’s burning oil every time he revs it.

wonder what it sounds like when it's running correctly.

Even our V12s rumble like a muscle car

There are builders in Australia that came with a V12 version of the LS.

11.6 @133!!! What?! Awesome! Great qtr. mile timeslip - even for today. That's just as fast as the test results Car and Driver magazine obtained for a McLaren F1 in 1997, and that was a nearly million-dollar car! Love C4's. My first Corvette was a Polo Green, tan int., tan top C4 convertible. Gorgeous car. My dad bought it for me as a graduation present because I had nearly all A's in college. I was so happy - but it's screwed with a lot of people's heads; they just couldn't handle it... I've purchased 10 more Vettes since. 1 more C4 (1996), 5 C5's (1999-2004 -2 ZO6s), and 4 C6's (2008-2011, including a 2010 ZR1). Great job on this documentary; I thoroughly enjoyed it.

I've been privileged to see this beauty in person twice at the museum. Sick!

I expected it to sound good. It doesn't. Also sounds like he's revving it just to keep it running.

That is a priceless gem of a car !

Would be cool to see someone build a modern interpretation with the V12 LS motor

sounds like a bad missing tractor. :(

I used to work with Ryan's brother, Ralph Falconer, at a pattern machine shop in Albuquerque, NM. Ralph was a super cool guy, full of old school knowledge and loved to talk about how he helped ryan develop this platform in the 80's.

Oh wow! I thought that this was gonna be some guy who engine swapped a Mercedes V12 into a C4. I had never heard of this car before this video. Thank you for the info!!!

I’ve seen this car on a few occasions at the museum and always wondered what it sounded like. Outside of the DOHC LT5 and the mid engine concept (No longer concept, I know) I always thought this was the most interesting oddball Corvette.

Is it just me or are there about 3-4 cylinders not firing? At first I thought it just needed to warm up, but that didn't seem to help. Def something going on with the timing there. 🤷‍♂️ Regardless, a V-12 C4?!! How flipping cool is that! Thanks for posting.

I had was not aware of this awesome machine, and I've owned three Vettes; still own one. Very impressive.

I remember reading about this in a Corvette magazine when it was built. The hood had to be lengthened to accommodate that LONG V12 which was basically one and a half V8s. ✔️

Love this thing! Thanks for sharing! I remember this from the article in Motor Trend, where they also tested other Vettes like the Snake Skinner and I believe a Guldstrand. The sidepipes were terrible, and I'm glad they're gone. It looks so much cleaner here.

Wow imagined they put this car in production back in the 90s 😱😱

Jesus that was a fuckin rush watching that monster creep around the parking lot! Unbelievable footage dude. I'm shaking right now.

Phenomenal car! Thanks for filming!

DAMMIT MAN!!, I thought my 1990 ZR-1 was badass, this thing is a beast. Thanks for posting, wicked!!! 👍👍🏁🏁🏁. It sounds like a P-47!

This engine is also used on the blue thunder P-51 mustangs.

I was lucky enough to see this car in person. Wish I were lucky enough to hear it in person too.

I think I have that Motor Trend Magazine when this Corvette was tested, along with other tuned Corvettes, I remember this car according to the test, reached 211 mph. It's a huge engine

My first gen Viper was a hoot but I would’ve seriously considered this if it was available and similarly priced. My emerald green Viper was $54k out the door so I’m not sure where this would’ve been price wise

I wish they did a light rolling launch. It isn't made of egg shells.

I remember this car being in Motor Trend magazine back when that issue came out. I had totally forgotten about it until this. Thanks for posting.

Nice concept....that year of Corvette had the best body style.

So many talking about how bad it sounds. Yeah, at first I was like, "What the Fuck!!??"....but started thinking, maybe they didn't have a flat plane crank in it, then they said it was originally a "marine engine" so it's probably angled differently than what a Ferrari or Lamborghini V-12 is angled at. Firing order of the pistons are probably different too. Then the exhaust is not the tuned titanium exhausts that we have come use to hearing from Ferrari V-12's, or Lamborghini V-12's.... Just a few factors to think about. With saying all that, I'm still sure it could probably use a good tune up.

Dang, this guy has no clue how to drive a shifter. Holy moly...

Employees casually walking by @ 3:38 are either not car guys or the museum brings the ZR-12 out every other day.

Amazing introducing of this legend!

Is it me or is it puffing smoke and sounds like it has a miss??

Judging by the blue smoke comming out of the exhaust, I can tell they took really good care of it... 🙄 Also it sounds like the guy drags the hell out of the clutch.

Holy shit, that rumble! So damn good! God I would love be in the presence of that car when it was started.

Best sounding V12 ever IMO because it sounds the most like 3 cross plane V4s or 1.5 V8s of anything I have heard yet. Very muscley sounding.

They should have replaced the fouled spark plugs so it would run on all 12 cylinders. And use a driver that knows how to use the clutch properly instead of the duffess that was driving it.

Disappointing they didn't rev it up somewhat close to the redline.

I remember this car from a magazine clip, years ago! Awesome!

I’m blown away by the 32 mph drive by on the road.

yoooooooooo id love me a boat powered vette ngl

Imagine how this would sound with Straight pipes ?

Wow, never heard about this car. Love your narrated vids so much Chris🏁

What insane madman at GM came up with this bonkers Corvette?

that car sounds sick.whats with all of the smoke.

If it hasnt done a burnout, it's not a vette

The way it sits today looks way better and more of a sleeper then the side pipe look

Very cool! I never knew Chevrolet shoved a V12 into a C4.

The engine sounds like it’s too big, as if it makes all the power at a much lower rpm like an industrial engine. All I hear is muffler on this thing, and it doesn’t sound much like a proper v12

Guy's driving like he sat on the toilet too long and his left leg is asleep

That interior, that's a true future dash, not some ipad stuck in some plastic accompanied by a 50hz whining sound. This vette is a gem and sounds amazing.

I've always wondered about this car since I found out about it. I love c4s, just the best

600cui = 9,83L :)

Lol Even this rare Super Vette has a light that won't turn up.

What a BEAST- never even knew it existed! It is too bad it never made it to production; a showdown between this and the Viper would've been AWESOME!!!

I forgot about this thing. Remember reading about it in R&T back in the day!

This is what you see when you play Forza Horizon 4 all the time every mofo Car swapped with v fockin 12s. Nobody uses stock engines anymore what a joke.

sounds like crap. Whoever was the exhaust engineer should be fired. hitting on 9 cyliners.

Very cool! 👍

Yo this is a true KZfaq OG right here!

Wow that's the worst sounding V12 of all time

The Viper didn't have a 10-liter-displacement. It was a 10cylinder, 8.4 Ltre.

That sounds Beasty ❤️

Amazing!

Who would have thought a C4 is one of the rarest and most powerful Corvettes ever.

That sound is amazing :o

Excellent video on a beautiful car 🚗

That crazy V12 Falconer engine was so powerful, it could shred the rear tires or burn the clutch to an unfamiliar driver. After testing the quarter-mile on this beast, they didn't bother to verify its top speed. The side pipes and wheels were changed and sent to the museum. The other monster Corvette tested then was the Callaway Twin-Turbo, now that was the "Sledgehammer". :-)

of all the "1 ofs corvettes", this one really is it

Hello DtRockstar1 my first Corvette was a 84 and it had been completely restored as I had just bought I did modify the twin throttle body just like the old guy would like lingenfelter on the intake and I got it up to 189mph it was fast and fun and not bad on gas modifying can be fun to do and made it go with no problems but unfortunately I had to sell it but one day I will buy another one or two that v12 Corvette is one I would love to have or build one one day I love Corvette motor cars completely Peace

Why the hell didn’t we get a v12 vette that shit would’ve set the bar high as hell for the later generations

It sounds like it wasnt running on all 12 cylinders, smoke is most likely the raw fuel, hardened valve seals, possibly washed out rings from the missfire if its been ran a lot like that. Id love to straighten it out. Glad it didnt fall in the hole

Cool content just found this channel and man wish they would built this vette

Probably a good thing this wasn't released. A lot of standard sports car drivers would falsely assume they can handle this thing and end up around trees.

imagine if they made a v12 corvette hypercar and only made 100 models would be insane

That looks awesome! I prefer without the side pipes, they don't really fit. Sounds great too.

Those wheels look terrific on it

At 3:26 the left flip up headlight got stuck, glad to know my 95 isn't the only one lol

one of a kind stand alone, my friend

Would be great to hear it again when it's actually running on 12.

Good ride that clutch buddy

Nice!

He killed that clutch for sure and it’s smokes pretty good. Lol. Sounds like it’s down a cylinder or two as well

No car manufacturer has even made a V12 for the general public. They just want V12s to be a luxury for the rich. That Corvette got real close to changing everything. Such a shame GM made a 180 and decided they don't want to be nice.

It does have a maritime sound to it like a high powered boat.

I may be crazy, but this body-style is prettier than any Corvette that came after 1970.

Thanks for the great clip! Literally 1st thing I noticed when getting on my phone this morning. So, I did have a question. Did you say it originally had side pipes?

Amazing wow
