I don't get it either. If memory serves the math whiz on this forum calculated 194 mph for the ZO7 and 206/7 for the ZO6.

Could this be a gearing issue?

I'm not an engineer by any stretch, but the "less than ideal" gearing from 4-8... since they are all overdrives.. could that not be providing enough torque to the wheels to overcome the aero drag and hit a higher top speed?

Other than the cars aero being a total mess (unlikely I think), this seems to be the only explanation that my simple mind can come up with.

The more little details come out about this car, the more I think what dumbass I can flip this car to for way more then I paid for it.

I'm just here cuz I like the dudes comparing top speed runs

sandcracker21

Almost every metric that has been released for this car has been disappointing..

Barely faster than a base stingray 0-60 and SLOWER top speeds.. wtf

The desperation in the Z06 haters is becoming frantic and desperate.
Just checked my position on the list and it's not budging.

This tells me the Porsche salesman and the haters have to do a much better job because what they are doing now it's not working.

Either that OR it is true that the folks with money have abandoned the corvette forum and just about nobody reads it anymore.

Please do a better job and improve my list position.

Thanks.

Or that people with the money don't want to pay more than double the cost of the base car for something that performs marginally better, if at all. In reality, the best play here if one just has to have a Z06 is to buy the lowest option 1LZ. Anything else is a waste of $.

I agree with that. Callaway seems to be just as much attractive with their debut of the supercharger. Probably pretty much north of $40 000 for the package though. But we shall see soon.

Too-Fast

Honestly, I love the looks of the C8 Z06, however I am starting to think the more cost conscience path would be to buy a 2023 Z51 and have a reputable shop twin turbo it with new DCT clutches and associated driveline enhancements and still be under the cost of a new Z06 (assuming the high ADM’s) with more HP.

Yea that option is/has always been available to Corvette enthusiast but there are a bunch of compromises that should be considered.
It's not all peaches and cream.

That Mercedes had an issue with porpoising that was similar to the current F1 car initially had at the start of this season. I was working for a race steward and was able to watch some of the live action and the motion was quite apparent. I think that the car became airborne with a combination of the bobbing and then hitting a bump at just the wrong time. I couldn't understand how Mercedes with their engineering expertise couldn't solve this problem and almost 30 years later still ran into this issue.

Tactical-Speed

A no option base C8? If so, MAYBE come in under, but not by much & you still have a base model & just lost a ton of $ modding (if you went to sell the car)

JABCAT

The Callaway supercharger pkg will probably be ~$20-25k. Now if you opt for all their aero, wheels, etc., you're going to be looking around $50k. So buy a $70k Stingray, send it to Callaway & you'll most likely have a car with better performance for a bunch less $ & full warranty.

Cadillac lists the top speed of the CT5 Blackwing at 200MPH...How can the base Z06 be slower?
Top speed is just for bragging, but this doesn't seem right.

Definitely disappointed again. My enthusiasm for the car is not what it was last Oct at the reveal. It may not be a "numbers car" but it *SHOULD* be a numbers car given the hype, the engine, the C8R pedigree, the performance of the base C8 and the outrageous price they are demanding. I would have never thought in a million years it was not 205 or more. My hunch is the dreadfully tall gearing starting at 4 and choking at 5 and beyond and perhaps the increased drag due to all those radiators and intake sizes?

I still believe it will be a fun car but from what we are learning, the performance is not matching the price increase.

JockItch

I had similar thoughts after we learned the 195mph top speed was for the base Z06 instead. Beyond gearing and the Z07 aero, the Z06 with its larger front and side intakes must produce a lot of drag. I don’t care about top speed, but the numbers don’t make a lot of sense.

I’m most curious to see what acceleration is like once you hit 4th… if that’s an issue no doubt I’ll be significantly more disappointed than these rather lackluster top speed numbers.

MattMD

Just doesn't make sense, how can the gears be so tall AND the top speed so low? Nearly 200 more hp than base C8 for extra 1 mph? Not to mention +$40k and probably 8-10 less mpg. Ferrari 458 which everyone wants as the benchmark for this car did 202 mph with 562hp 13 years ago.

It absolutely should do 200mph. Hoping whatever is reporting 195 is fake news.

AustinVetter

I used to have a street stock car in NASCAR (small time) that I would set up for my friend who drove. You block off the radiator intake where you can to gain MPH at the expense of cooling the engine. With the Z06, the size of those side intakes are massive and *may* act as parachutes. The openings on the front of the car are not small either. It *could* be that the engineers chose to err on the side of caution and provide more than adequate cooling even thought they knew it would take a pretty big hit on top speed. IF that is the case, you can't really blame them and this might be why it was stated that this isn't a numbers car.

UnhandledException

I dont think its that simple. Take a look at the new GT3RS. Massive radiators. Lots of openings. 1900 lbs of downforce (vs 734 lbs of Z07). Yet top speed of 184 mph. More downforce doesnt always mean horrible top speed. You have to be very smart about channeling air the right way. If the Z06 was $89k and a loaded Z07 $125k, we could just look the other way. But we are in past $175k into $180k-$190k fully loaded. At that price point you have got GT3s, Turbos with a lot better engineering and thought process around the complete package (vs just spending a ton of money on one thing - engine). By pricing this car at those levels, GM put themselves at a tough spot. You are at GT4RS levels (in fact above those levels) price wise. That car will be head to head with the Z06 in a track. Has a top speed of 196.
