Chevy brought a handful of 2023 Corvette Z06 models to this year’s SEMA Show in Las Vegas, and GM Authority was lucky enough to capture a video of the vehicles performing a cold start and revving their naturally aspirated V8 engines.
As we already know, the 2023 Corvette Z06 is powered by the newly developed 5.5L V8 LT6 gasoline engine, which features dual overhead camshafts and a flat-plane crankshaft. This engine puts out an impressive 670 horsepower and 460 pound-feet of torque, making it the most potent naturally aspirated V8 engine ever installed in a production vehicle.
This high-revving V8 sounds like it’s pulled from an exotic supercar like a Ferrari or McLaren – making it a major departure from the Small Block V8 engines that powered previous Corvette Z06 models.
Our video shows an Artic White 2023 Corvette Z06 Coupe starting up before the driver gives the vehicle a few quick blips of the throttle to let onlookers hear the LT6 V8’s unique exhaust note. As the white example pulls onto a nearby stage, an Amplify Orange 2023 Corvette Z06 Convertible that was parked behind it then starts up and pulls onto the stage. The orange model is also equipped with the optional Z07 Performance Package, as indicated by the large rear wing and other aerodynamic components.
To our ears, the 5.5L LT6 V8 sounds very similar to a Small Block V8 at idle, but begins to sound more high-pitched and exotic as the revs build. The 2023 Corvette Z06 makes peak power at 8,400 rpm and has a sky-high redline of 8,600 rpm, so drivers will have plenty of incentive to get into the gas and let the LT6 V8 breathe a bit.
Want to hear the 5.5L LT6 V8 for yourself? Check out the video embedded below.

Awesome! On the list!
Almost worth the price of admission
GT350 sounds better!!!
Yes, a change of muffler might make the Z sound like a Ford, however, the lil GT 350 isn’t even in the same league with this Z. The Stang can only muster a 4.2 second zero to sixty and the Z does it in almost 1/2 the time @ 2.6 seconds. Even the vaunted GT 500 is sluggish at only 3.3 seconds to sixty…Bye-bye Ford.
It will all be over in time with Let’s Go Brandon’s mandatory electrics.
Why is GM now Hell bent on building battery factories and going all in on electrics?
The GT 350 has a different firing order and is basically a cobbled together modified 5.0. It burned oil like crazy and blew up in many cases. That’s why it’s discontinued for engine issues just like the Focus RS with blowing head gaskets with open block. Don’t even mention the 2 in the same sentence.
@Earl
yea sure that GT350 “sounds” better, but it cannot even compete with the C8 Corvette on the track.
Sure the GT350 barks louder, but the C8 Corvette bites harder.
It’s too bad that at this SEMA Show GM is not having in the South Hall parking lot test drives with attendees like in years past. Guess Covid 19 has a play in this.
Also Ford is not doing drifting this year in the Center Hall’s Western parking lot. Awesome event when Ford had it with the Stangs and trucks. Oh well, maybe next year.
Ford did host the Ford Out Front events, including drifting from Mustangs and race-ready Broncos this year. It is a fun event indeed. Back to the matter at hand…
Is the wing carbon fiber?
I really want 3 , a Z06 coupe, a convertible and the Z07 all bespoke with coordinated graphics design to give them a full custom one of . Thanks GM , it’s about time
Vroom, little bit fancier than my 98 c5
Beauty at its finest. The C8 Corvette is the greatest car ever made, considering how much car you get for such a low price.
