Oh, I'll gladly use V4 and Stop/Start when I don't need max power to drive like I want! I understand that only about 15% of the energy in the gasoline that we use in our cars propels them forward. 85% just goes to heat the air via:
PS: re Z-Mode: When gas prices were very high, conducted a test for two full tank fulls operating my C8 Z51 in ONLY Z-Mode that in my rural goes typically not past 5 gear and another in ONLY MY Mode set to Sport where it used V4 and all eight gears. Driving about the same (in my case often pretty aggressively I got ~1.5 mpg more in V4 and using all 8 gears. No big deal. Frankly who needs an 8th gear with essentially 0.33: 1 dif ratio. Heck 4th gear makes it like 0.88:1 OD and 5h like many slushboxes with a 0.68:1! Nope don't feel bad driving my 8.2 Liter BB street rod with no OD ratio that gets poor mpg, That is what I elect to do.
Thought Corvette folks were smarter than AOC who pushes only EVs, eliminate gas stoves etc. It's a shame, some are no better and won't accept minor inconveniences like V4 and Stop/Start! Yep that just makes those in charge force ONLY foolish EVs.
- Radiators that transfer heat from coolant,
- Out the exhaust pipe
- Idling
- Friction
- About 1/4 of what gets to the wheels goes into heat when we brake (Feel good when my E-Ray shows braking going into charging the batter. Feel better when I use that battery power to reach 60 in 2.5 seconds.)

More silliness....and irrelevant....stop start and v4 all cost more than they save and most people hate them.....just like the skip shift on the older GM stick shifts...I bet you were all for that too......

I forgot my previous C8 Z51 HTC with NPP had AFM, I put AWE Track exhaust on it and it sounded terrible in V4 mode, so I would have to run it in track mode or manual mode to bypass it, there went my gas mileage anyway.
My current C8 Z06 does not have AFM and I love hearing it purr on the highway. I heard a rumor that they will add AFM to the 2025 Z06 to save the $2000 gas guzzler tax, what a way to kill a great car.
Please make it optional, I will gladly pay the $2000 tax.

I had a gen 2 viper and remember the mechanical skip shift below certain rpm,s. It pisxes me off and I just jammed the lever through. Something broke but car shifted normally there after without the mechanical interference.

You seem enamored with AOC....I'm not surprised...

Yep happy to get their faster than a C8 Z06 with ~25% better mpg! Yep technology can achieve the best of both Worlds!
Z-Mode Power set to Track: Ride to Sport. In My Mode, set to Sport don't feel when it's in v4 and don't turn off Stop/Start both none obtrusive!

SIDEBAR
Up to my C8, EVERY DD I had since building my 1st car when 16 (a '41 Ford I stuffed in an Olds engine in 1959) had bene a standard shift. Heck enough of a purist until I moved South in 1985 and bought my 1st Vette I never had hp robbing AC! Lived two summers going home home soaking wet on hot summer days in a Turbo compact black car I had in CT! Crazy!
Was concerned about getting an automatic Vette (had GM used their own manufacture "slushbox turned transaxle," my fear, I'd be driving a Porsche.) BUT thought I would give a DCT a chance for my 6th DD Vette. Met a fellow who was similar but bought a new Ferrari as like the Vette no choice DCT or nothing (been that way since ~2012.) Said he always drove in Manual Mode pulling paddles. I did the same for the 1st month.
BUT there is only one way out of the CC where I live. A twisty rural road that has a stop sign leading onto a 4 lane divided highway with often heavy traffic going and coming to Myrtle Beach. We're an hour from the Beach BUT 1st road to get to I95 South and RT 20 West. Cars going ~70 mph, closely packed. When my 500 mile break-in was over accelerated rapidly from that stop sign to merge with heavy traffic. However have to make a 90 degree turn and paddles out of position. Hit the rev limiter at 6500 rpm in the blink of an eye in 1st. C8 waiting for me to pull the upshift paddle. No fun having traffic coming up fast on your rear while fumbling to find paddle to go into 2nd gear! Heck all happening while you hit a brick wall at 34 mph as all fuel to the injectors shut off! Did that a few times and Forum Member showed why he always drives in Z-Mode power set to Track. Turned out it was shifting just like I was in Manual Mode AND the way I shifted my two prior standard shift C7s.
The DCT is smart in Z-Mode and it shifts all by itself just before the rev limiter. Been driving my 2020 C8 that way ever since! Heck don't even have to downshift for the turn from that highway to our 25 mph rural road. Just apply the brakes aggressively so those RV's coming from the Beach don't have to slow for me and it downshifts 2 even 3 gears rev matching each all in the blink of an eye! I call it Rev Match Music!
Did that for 3 1/2 years with my 2020 C8 and the same with my new E-Ray!

Someone will come up with a solution to the useless and costly v4...and you can keep pretending you're saving the world...its all good...

Followed F1 racing in magazines not long after! Have watched F1 using hybrids for 10 years. They felt pressure to be more environmentally responsible and showcase the use of more efficient and sustainable technologies. Today they are besting race times on some of the same tracks, same length as 10 years ago when V-10 and V-12 engines were turning 20,000 rpm and guzzling gas with many pit stops. Today no gas pit stops allowed. They are producing ~1000 hp from much more efficient 1.6 Liter engines limited to 15,000 rpm AND hybrid electric power using a battery smaller than the 90 lb, 1.9 kWh in my E-Ray! Yep we can go fast, have fun and Waste Less Gasoline Energy!
I feel like Andy Cowell, Managing Director of Mercedes High Performance Powertrains, when F1 was planning to eliminate one of the methods they use to charge their hybrid battery because of a foolish reason it cuts down on that "nice engine noise," (the energy saving function that used otherwise wasted turbo energy when boost was not needed.)
He said: QUOTING: It provides 60% of the electric energy used to power their F1 cars and contributed 5% of the current engine's thermal efficiency. We'll have to come with various systems and devices and that will probably involve burning some fuel through the exhaust, which doesn't feel the most honorable thing to do as an engineer!
I feel the same, we can do better without foolishly eliminating fossil fuel use!

I'll be kind for the Saturday before Easter and just say how I feel about reducing 85% of the gasoline energy i put in my car just turning into heat! Been following drag racing since I saw Don Garlits go 8.36 seconds in the quarter at Montgomery NY Track in 1958! No blower just a Chrysler Hemi with 8 '97s. Saw Richard Petty and his Dad at that track in 1959. According to his cousin and crew chef at the time, Dale Inman, who I asked, that was the one time they were there and recalled they slept in the flatbed truck cab they used to transport the car at the time. (Sponsored Petty for >15 years.)
