Edit 1: Up until about 8.5 minutes into the video, the bottom left corner reads 760 HP for the Z06, rather than the correct number, 670 HP. I eventually noticed I wrote this incorrectly, but not until halfway through filming. 🙂
*FUN FACTS*
Hard to make everything fit in one video!
– Why turbo vs supercharged? This maintains the rev-happy nature of the engine, without bolting on a huge spinning mass (supercharger). Also has greater efficiency, and 1,000+ HP would require an enormous supercharger.
– Why 1,064 HP? Why not some rounded, clean number? Corvette engineers state they're only goal was to make as much power as possible from this engine on pump gas. 1,064 was that number! No weird rounding, just aiming for pure performance and hoping to push it into four figures, which they exceeded nicely!
– Top speed is over 215 mph (it has the power to do way more, so I expect this number is higher!
– The car has 1200 lbs of downforce at top speed with the ZTK package aero – highest ever for a 'Vette!
– It's RWD, did I mention that? Ha!
– The exhaust alone produces 37 pounds of thrust!
– The turbo wheels are made of MAR, and can see a steady state of 1,000ºC!! They see peaks up to 1,030ºC. That's hot.
– As far as fueling strategy, port-injection only is used at idle & light loads. DI is blended in for mid & high loads (and of course very important at high loads). Using DI-only is rare (without port), but is used on cold-starts.
– There are 15 heat exchangers on the vehicle to handle all the cooling needs.
– It has a new J58 braking system, and 'Vette engineers say there is magic in the rotors, which have better heat rejection and better durability.
– The standard ZR1 is a softer version (ride dynamics) of the Z06. When you go ZTK package, it's no compromise, and all about lap times. Stiffer, more downforce, track weapon!
Porsche better find some more revs or bigger turbos. That flat 6 cannot compete.
1122Nm of torque for the rest of the world,as purely "more is better" isn't very engineery 🙂
My C8 Z51 Stingray does 0-60mph in 2.8 sec.
I love that it makes over 1000 HP and is not a hybrid. I have no desire to plug in my cars. It could been lot faster especially 0-60 if it was all wheel drive though.
The Bugatti is 1000hp naturally aspirated. So 🤷 corvette engine isn't that impressive.
One question I have is why didn't they make the driver side turbo go to the passenger side engine bank and vice versa instead of the 90 degree turn to have each turbo correspond to its same side engine bank? I'm still amazed at what they were able to do with NO hybridization. Crazy!
Did you get a Wilderness Crosstrek?
I can’t wait to see the police “chases” with this thing
Corvette engineers, Hold my beer moment.
Isn’t the street MMR rated at 1250-1500HP for $30k likely a more reliable motor…..
What the frunk!!!!!!
Because it’s just a Corvette, that number doesn’t really “register” for me. I have to think for a second, “oh ok, yeah, that’s a lot.”
Thank you for the deep dive as always. I figure if I donate a few organs I can put a good down payment on one 🙂
Jason this was fantastic. Your enthusiasim is contagious.
Who is going to be able to drive this thing at its potential on the streets? They should require a special license to operate the ZR1.
Swan Song for ICE cars. Nice and probably collectable, but as you say, hybrid or electric will get you 0-60 quicker

I want a crate version but the last time I ordered a crate I got a Nissan Cube.
