- It's the only non-turbo engine in IMSA's new WeatherTech SportsCar Championship hybrid GTP class and it makes incredible sounds while generating a ton of power.
Take a look at the power behind the Cadillac V-LMDh which makes its racing debut at the Rolex 24 At Daytona.

Wow. I'm a big GM fan and totally missed this one. I watch Le Mans yearly and cheer the Corvette on. I did not realize Cadillac had planned to re-enter Le Mans. This engine was impressive. Cadillac finished race at 3rd and 4th. I know its not first but it seems impressive for this engine. I'm happy Corvette one 1st in the GT Class. Go Chevrolet and Cadillac!!!!
You missed a treat. Great race. This car did really well battling the heavily favored Ferrari and Toyota teams all night. Cadillac even lead the race for a short while.
A General Motors fan? Are you serious?
This engine sounds awesome !
Marshall, you are hitting it out of the park with this series. Keep up your good work. Thanks. I'm tuned in this weekend!
Your videos about all the engineering and tech involved in the cars should be public needs, thanks
no wonder Cadillac is the only American team to win 2023 Lemans
If chevy ever decided to put this engine inside the new z06 intead of the flat plane one, i would be totally okay with it 👌.
It sounds better.
Maybe the in the Grand sport instead
MP this is the best gtp content out there great work. Keep it coming it’s awesome
Not just the best GTP content, this series is some of the best motorsports content out there, period.
When they first announced that they’re using a 5.5 V8 I figured it was based on the C8R engine.
That or the old DPi engine with a higher rev range. Building a completely New one is insanely cool, but absolutely nonsensical.
@@TheNecromancer6666 The old DPi engine was a single cam in block, overhead value, push rod engine with a cross plane crank shaft. This new engine is double overhead cams with a cross plane crank shaft!
@@byates59 Apparently so yes. The old one was basicly a race modified LT1. This New one is a 100% Prototype engine. Insanely cool but still kinda insane.
I still have a sneaking suspicion that it's the C8.R block and heads with a crossplane crank and corresponding firing order to give it that unique sound.
So if we got a cross plane in the new Z06 this is what it might sound like, interesting…
Great series!!! The Caddy sounds awesome.
Is there a video coming for the Porsche engine? I get it if it doesn't happen but its the only one missing !
Only an American would call a 2.4L engine tiny 😂
Well I mean 2 Liter Turbo is the standard I guess. 3 Liters are very common. So 3,5 and up counts as Big....
I mean we have road going 6.6l's and 7.3l's that come in everyday vehicles for moms to drive their kids to school in so yeah
Only a European would call 2 inches gigantic
I❤ GM
Sooo can I buy one?
it sounds like R1M is this using a Cross plane Crank ??????
Yes, it's a cross-plane crankshaft.
Awesome
pretty sure the DPi engine would have revved to like 11k if it was allowed to by imsa. the technology was there from the Cup program
Is this a Flat Plane crank engine?
Unfortunately it cross plane engine
@@Unknown-3455gamer Not the one they have been using . The new one they will be using in 2024.
Of course GM makes the only N/A engine in GTP. From scratch too. Typical GM shenanigans
This is what GM could put on road cars if it wasn't for all the epa regulations and electronics that modern cars require. Pure compression and cam design optimized for performance, nothing more. Put that dame engine in a street vehicle and it's game over.
You are still getting the Power numbers wrong. Its a 500kw wheel power performance Target. But the engine Power is 15% higher, around 575kw. So its mot a 670hp engine. Its a 770hp engine.
bruh wdym there not allowed over 670
@@mememanfresh Did you read my comment? The Power is measured at the wheels. So including Transmission losses. Which are around 15%. That means the 500kw at the wheels are 575kw at the crankshaft. Also they don't have a hard Limit they have a Performance Window which is between 500 and 520kw at the wheels depending on the BoP
My 2 Step limiter is set at 8800...
OHV or DOHC configuration?
The latter I believe
Im pretty sure its dohc
DOHC with a cross plane crank shaft!
Is this the corvette c8 engine??
Isn’t the Corvette C8 Z06 using a 5.5L V8 that revs to 8600rpm? Though GM should be getting plenty of xp with DOHC NA engines in the C8.R
They are different motors.
@@captaintraction4024 okay thanks. Don’t know GM very well
@@StreetComp the Z06 has more in common with the C8.R engine.
Jackson Storm engine 🤩
Is it a crossplane V8?
Nope you can tell by how it sounds more like a classic American V8
So yes... it is a crossplane V8. Not a flatplane.
GM built 5.5L nat asp V8 with 670hp? is this a repurposed C8 Corvette Z06 engine?
No. It's cross plane crank while the Z06 is flat plane crank
@@professorsergio3819 same engine bruh just crossplane
@@mememanfresh Its not the same engine, he literally said it a new purpose built motor
What's with your head all of you Americans?
2.4 liter displacement is a tiny for you guys?
Having too much displacement like a 5.5 liter LS engine still call it small block for that displacement WTH.
XD
You have to remember that an LS engine is absolutely microscopic relative to its displacement because of its pushrod design. An LS7, with its massive 7 liters of displacement, is both lighter and has smaller exterior dimensions than BMW's 4 liter S65 V8.
Seriously doubt that GM could ever make a competitive F1 power unit.
Why ?
With the help of Illmor they would have no problem
You have no solid reason to say that, GM is one of the biggest manufacturers in the world, why wouldn’t they?
@@mikejoness2k not just biggest but makes power units in all different performance areas ,the comment doesn’t make sense . If Mercedes,Ferrari,redbull can make them why wouldn’t gm
That’s what they said about Mercedes
Is it s crossplane or flatplane crank because it sound like Crossplane but what i can se with the high rpm it must nearly be a flatplane
cross obviously
