Hidden in plain sight. That's the best way to do things, knowing all the speculators will divert attention elsewhere.

My guess is that it's a 48V mild hybrid. BorgWarner's P2 Module is already in production, with an off axis version expected to be launched in 2021, just in time for the C8 to enter production. The P2 is perfect match for a DOHC V8 in need of low end torque and a car model in need of higher fuel economy ratings.

Edit: I've been advised that the Blackwing LTA architecture will probably be the ONLY V8 architecture offered on the C8. Perhaps the base really will be an naturally aspirated LTA variant with mild hybrid assist to augment the low end?

Play nice!
Lol what. You think a base c7 is as fast as a c6z? You need to get out more...

I seem to recall 0-60 being within driver error and 1/4 as well. The Z06 traps a hell of a lot faster though iirc.

Depending on the track, I'd wager it could go either way. But if you have longer straights forget about it. The Z06 should walk away from the stingray every time. Short course with twists is probably a drivers race. the torque curves are a lot closer than you'd think actually...

You are right!, I need to get more as the stingray was the 58th fastest around Laguna Seca and the C7 z06 was the 88th fastest! Keep trying , flame suit on!

To clarify the Fastest Laps list, I was there viewing these three runs with Motor Trend. All driven by Randy Pobst. All three of these tests were quite varied in the weather conditions. Check out the Car & Driver Lightning Lap Test. The C7 GS(2:47.1) walked on the C6 ZO6(2:53.5).

27th C6 ZO6-ZO7 1:34.43
41st C7 Grand Sport 1:35.62
58th C7 Stingray 1:38.28

Motor Trend has a Ď06 Z06 at 3.5 0-60 & 11.5 1/4 mi at 127mph compared to a Ď17 Grand Sport 3.9 & 12.2 at 116mph.

Like I said, within driver error for the average guy. I probably couldn't hit that 11.5 or 12.2.

116 vs 127 is all we need to know. These cars are leagues apart. With heads and a cam, the c6z is significantly faster.

0-150 mph a c6z06 is a lot faster 4 or 5 seconds quicker then a base c7 and almost 1 second quicker then a c7z06 . Top speed the c6z06 factory estimate is 198 mph. The c7z06 stage 1 aero is 195 mph and takes a day longer to get to top speed then it takes a c6z to get to top speed. Comparing the c7 and c6 z06ís from a rolling race 40 to 150mph then on up to top speed the c6z will be so far ahead you wonít see itís tailights if your driving the c7z.

0 to 60 c7z is quicker and 0-100 c7z is about a half second quicker then the c6z mainly because of the huge c7z torque with the 1.7 supercharger. But up high the c7z Peters out with the little supercharger. That and the c7z being heavy with barn door aero supposedly good for track downforce make the c7z feel sluggish. Having had both cars I much prefer the normally aspirated motor.

The mid engine c8 if it gets good traction would be better served with an engine that behaves like the normally aspirated ls7 without worrying itís owners that it will drop valves .

Your assessment was true for the C5z and the base c6. Wasn't applicable to the C6z and C7 base. And if the C8 base is N/A there is no way it will be applicable to a 650hp C7Z in the trap speed.

They might be able to run comparable lap times on certain tracks, but thats only one comparison.

I’m not saying it’s a bad thing, just that it is only one aspect of the performance measure.
chassis rigidity of the c8, the dct , the rear weight bias all favor consistent acceleration performance.

we are on a forum speculating about where the c8 will land in performance to the c7. Of course we are bench racing..lol

zero to sixty with lets say 500 hp and we will see zero to sixty acceleration times to equal 3.3 seconds as a best guess which is halfway between the c7 z06 manual at 3 seconds and the 3.7 seconds on the c7 grand sport automatic torque convertor automatic..give or take a few tenths.

yes the trap speed of the c7 z06 with 650 hp will be quite a bit higher than the base c8...but for most of us....regulalr sports car enthusiasts will enjoy the under 80 mph consistent increase in performance over the already amazing c7 grand sport...

the topic of this thread is where the c8 standard version, maybe the z51 version will land compared to the c7 lineup..

and we are bench racing as we shoot the breeze on where the c8 will land compared to todays corvette lineup.

that was the premise of the thread as we all wait for the official gm release.

traditionally the corvette engineering team wows the automotive world with the release of a new generation.

thats one of the reasons why corvette is an iconic brand...the best corvette is always the newest...at least for the past couple of decades..(none of this diminshes previous generations of corvettes)

My 2016 A8 Z06 in factory condition down to the tire pressure ran 10.92 @ 130MPH and I am no professional driver.

The base will get base performance just like the base C7. $60k isn't getting you 3.3 0-60. You'll pay $100k for that and even more for Z06 2.85 0-60 just like the C7 Z06. It's funny reading folks thinking a $60k car is actually a $300k car.

You're out of your mind.

Maybe YOUR c7z06. Not mine lol. Or the numerous others who have owned both cars.

Tony,

The C8 section of the forum certainly has generated a lot of controversy and has gotten nasty. That's particularly true when certain individuals proclaim things to be true with no credible evidence to support their assertions. That starts flame wars and pissing contests. There's nothing concrete to actually discuss.

The C7 General and Tech sections are generally very civil, and the same as the C6 General and Tech sections were a decade ago. They are helpful places and great resources. The C8 section is an anomaly, and since there's no car to compare notes on, it can't be a useful resource.

I took an 8-year vacation vacation from this place between '08 and '16. When I returned, the place seemed exactly the same. I wasn't around for the comparable speculation on what the C7 would be like before introduction, but I suspect it was similar to what we're seeing in the C8 section.

Visit somewhere else, and you'll see entirely different behavior.

I am hoping the c8 brings some big improvements ó lighter weight and a normally aspirated motor that revs high.

the numerous c7z owners donít want to admit or are to afraid to admit the c6z is a better acceleratiing car up on the big end. Stock for stock then the c7z.

Op, The C7 base is NOT the same performance as a C6 Z06, The C6 is hundreds of pounds lighter, better brakes, more hp/tq...Lol

Wrong. No way you need to spend anywhere near $100,000 for a Z06. The participating dealers on this forum are great and will put you in a Z06 for tens of thousands less than that #. A C7 Z06 is an import humpers nightmare as it will bitch slap their European dream machines at 1/2 to 1/3 the cost. This same crew will go into full meltdown when the C8s take center stage. .

100 % correct. At best, the C7 base w/Z51 would be the equal of the C6 GS. The C7 could not match the C6 Z until the C7 Z came out.
