The design philosophy on the C6 was correct, but wrong on the C7

If you have a new Zo6, please take it to Road Atlanta in August and report back if it even makes one full session, thanks.

Get over your hatred for FI. It's here to stay. Full stop.

BTW, if you run "the ****" out of your ZR1 at 100 degrees ambient ALL SUMMER LONG, then you better than anyone have just highlighted an extreme failure on GM's part with the Z06. People here can't run "the ****" out of their Z06 in mid 70's without overtemp warnings on multiple systems. An instructor at COTA overheated a Z06 at 75F in 3 laps.
On the FI issue as the "future" that is inevitable...I think that's possible only if there is no resistance. Fact is, we still see Porsche and Ferrari putting out very potent N/A platforms, and I can bet they will continue to...by shaving weight or using hybrid systems. GM has worked hard to develop alternative construction techniques with carbon, aluminum, etc. They clearly understand weight is a factor of the future...for that reason, I don't think N/A is facing a certain death.
In the end, no one cares what makes the power...they just want it reliable. If you label a car a track car, then make a track car..period.

Your ZR1 obviously is not stock or you don't run the **** out of it as you state.
Come run the "**** out of it" at NOLA or Road Atlanta in August if you want to test it.
If a FI car isnt factory built it has very little chance of survival in the deep south in summer,and thats a fact......seen it way to many times.
Even factory built cars have a very hard time in the Deep South running in summertime

Pretty Close believe it or not, A little bit less at Barber as compared to NOLA, still have to fill up at lunch and at the end of the day in my LS6 powered Z28.
Have yet to run the Z06, but I assume the consumption will be similar.

You might notice I put the laughing smiley behind it because it was a semi-sarcastic statement. I've done many various tracks (Road America, PittRace, Monticello, etc) but I can't say they were ever in the same car so...I've never compared directly really. I never ran my cars below a solid 1/4 of a tank, nor did I like to run full...I always did a mid day refueling, like you stated.

I've always wondered by Corvettes that are open topped don't come with factory roll over protection. Especially since it could be a simple as keeping, perhaps reinforcing some version of the basket hoop (where the rear hatch attaches) from the coupe. Any track-able car has to have roll over protection, why make it have to be an added on kludge instead of standard from the factory. Most other high end open top cars come with this, why not the Corvette?
It can't be weight, as the added parts required for a track likely add more weight than a well designed factory included roll over protection system would. And the cost can't be that much, since the coupe already has the basic elements of a ROPS.
And it can hardly be some liability issue, or other manufacturers would avoid including ROPS, and to date, the better brands have ROPS and have for many years.
How in 2015 can Chevrolet be selling an expensive high end sports car without a Roll Over Protection System? It ought to be a standard part of every open top car made, especially the flagship Corvette.

I have been reading lots of threads about engine and transmission overheating in 2 and 3LT's and lots of electronic glitches. I have waited 3 years to buy a new C-7 based upon hoping the bugs would be worked out and have just ordered a new 2016 - has the engineering team fixed a lot of these issues in the 2016???

The C6 had a metal frame for the base and convertible cars and a light aluminum frame for the high performance versions (Z06, ZR1). Rule #1 for all great sports cars is that they be light and nimble and the C6 Z06 is a great example of this. Also, there were no complaints from anyone that the frames on the C6 were not strong enough or were too flexible. On the C7 you made a stiffer aluminum cast and hydro form frame for all corvette models. Why, so everyone can take the roof off and the convertible can use the same frame. But the C7 frame is heavier than the C6 aluminum frame and so the C7 Z06 and C7R are burdened with extra weight. Cylinder deactivation is the wrong technology for the C7 Z06 because of all the extra weight. Power adjustable seats with electric heaters in the Z06? Who would take a Z06 out on a freezing day with those track tires on it? Clearly everyone forgot Rule #1 on the C7.
A number of forum members have asked me to rewrite the question. I have included their input and we will use this updated version moving forward.
There is a segment of Corvette loyalists that want a track originated car. The C5 and C6 Z06’s are perfect examples. Unfortunately the C7 Z06 doesn’t follow the same design philosophy as the previous Z06’s. It’s much heavier, overheats, provides an open air experience, and has rpm limiting cylinder deactivation. You did succeed in broaden the appeal by adding an automatic transmission option, but by trying to broaden the appeal beyond the track, it is no longer the purely focused track car of previous generations. Why did you call it a Z06 and I hope you understand what we really want in a Corvette Z06?
