C8 Z06

Please...Chevrolet didn't TRY to make a flat plane/DOHC engine until when??? Surely not 2006 and not 2016 either. They probably started on the LT6 in 2019. I'm hip it's "Ferrarichat" but let's not get crazy here. NOTHING about the 458 engine was new/cutting edge/never seen before in 2006.

 

The hard part was designing a Ferrari engine to fit a Chevy budget.
.

 

Its the caddy blackwing engine with a flat plane, so the budget was spread. More to the point the ferrari engine is not so costly to make its the markup. If it costs Gm 20k to make the motor thats one expensive engine.

The question for me is how much this motor and suspension will tranform the car. Recently did a drive ina C8, its really impressive, for a vette. But its a big hulking car. Maybe the z06 is more the american Aventador than GT3..

 

i think the engine designer said it was not based on the caddy engine.

 

No it's not. I have a CT5V Blackwing. It has a tuned up LT4 from the previous generation C7 Z06.

The LT6 in the C8 Z06 is a completely different engine.

 

Yes thats the motor you have cause they scrapped the good one 18 months ago.
But Cadillac did make for its big blackwing a quad cam v8 about 2 years ago. Its that same block and heads as in the vette motor. I think they only made 1000 before they decided they're an suv company and stopped building the car. In other words it was a joint program and Gm assumed there would be lots of sales from both brands to justify the investment.

 

"The LT6 is based on an all-new engine architecture that isn’t shared with any GM small block engines, or the bygone Cadillac Blackwing V8 engine which was also DOHC."

"The LT6 is a 5.5 L; 333.4 cu in (5,463 cc) DOHC flat-plane V8 engine designed by General Motors. It debuted in the eighth-generation Corvette Z06, and was unveiled on October 26, 2021. It is a clean sheet design, mechanically unrelated to both the LS based engines and the Blackwing V8."

I hadn't thought of that. Brilliant!

 

Also the LTA (the RPO code for the twin cam Blackwing engine) was undersquare, had start/stop...the engine has nothing to do with the LT6 OR the LT2

 

Probably the bigger challenge is building a reliable engine that gets used more than 2K miles a year and can be easily serviced without needing $1000+ annual service.

Time will tell about the reliability. Even though they ran a very similar 5.5L FPC engine in their race car, it was not pumping out 670hp.

 

You don't see 458 engines blowing up everywhere so its possible to do. You just have to properly engineer the engine to meet the task, then do the proper assembly.

And remember a race car driving 24 hrs straight at full throttle and at high speeds / cornering / G loads is a lot different than how a street car is used.

 

Sounds familiar.... and very Corvette unlike. I really like the new rear wing. Makes the car look sleeker.

 

not really FORD did a flat plane V8 for a mustang budget once again designed like a Ferrari engine it was in the GT350 and GT350R and still is.....

 

^^^^
"Was" is the operative word here...the GT350 and GT350R have been out of production for 2 model years now.

 

Ford basically took an existing CPC engine and converted it to a FPC leveraging a lot of existing parts to reduce cost.

What is impressive with the LT6 engine is that GM did a clean sheet design and the engine does not share any parts with prior engines. Clearly this is the end of an era for ICE engines and GM wanted a swan song finish.

Like the 458 was the end of an era, so will this Z06. From now on its hybrids and smaller displacements.

 

The ZR1 is rumored to have the 5.5L FPC with turbochargers, but it could be hybrid instead. Depends on if/what the Zora will be. Who knows...

The Z06 will be the last NA based Corvette for sure and should be in demand for some time to come.

 

I think GM is going to dip their toe in the hybrid world with the "eRay" and then possibly a crazy ZR1 (or Zora) with a tricked up LT6 and BIG electric motors (1,000HP combined is this week's popular prediction)

 

ZO6. Coming soon to a neighborhood near you and blowing away 458's. O-60 2.6 sec. Pulls 1.3 lat G. 200,000 miles reliability tested. ZR1 twin turbo version 850 HP. Eray lt2 + electric for 600 HP.Finally ZORA. Yep twin turbo electric with 1000 HP. Currently there are at least two supercharger and two turbo systems avail for the c8. 700 HP easy. 8-900 with Dodson transmission clutches. Some completely built motors with forced induction pushing 1300 HP currently. Oh and c8 with bolt
Ons headers,exhaust,intake,throttle body gets you 560 see lingenfelter and others. Ain't American aftermarket and ingenuity great.

april 2 joke?

 

Totally bogus. Like last year when VW changed name to Voltswagen.

 

oh no!
i demanded my deposit back and i was #1 on the list

 

The Z06 is coming, but so is the future to all electric, but not just yet.

 

I hope it's fake news, but the article looks legit to me.
