C7 Z07 vs. GT-R Nismo

And what price diff are we talking about here 115K to 150K Z06 to GT-R.

well, I can't afford either so I guess it doesn't matter.

I have seen ZL1 to base GT-R comparison that gives ZL1 the "More Fun" to drive, and we are taking a $60K car to a 95K car.

I say GM is doing a great job of giving customers an awesome, more affordable machine compared to what its competition is, performance wise.

Oh, and then there is that awesome sound a V8 gives you over a V6...

If there was no GTR model in the Z06's price range then okay but there is a $115K GTR track edition not to mention a base GTR is over $100k. Also, a 3LT Z06 with Z07 package is about $100k before any more options. The Nismo GTR is $150k before any more options. The models tested makes about as much sense to me as a WRX vs SS or STI vs V6 Camaro.

I don't see how this isn't a perfect comparison! I mean they are polar opposites. AWD vs RWD, V6 vs V8, Japanese vs American, twin clutch vs manual. the only thing that doesn't fit is the price. and that's what makes the vette the performance bargain. this is a great comparison.

Enough with the unfair comparison talk. We all know this is the target we want to beat.

Seems like a fair comparison, after all, it is the top performance model Corvette available right now. The GTR costs more because they don't have a lower priced model to support the development and keep the cost down on the high end models. Plus it just doesn't sell well. If GM only made the Z06 go ahead and add 30k to the price. IMO the Z06 fell short here, they really have multiple advantages over Nissan that they weren't able to capitalize on.

Retest. Corvette they tested...had the rear suspension out of alignment.

They are still having overheating issues.

As in previous tests, the Z06 got very hot during lapping and pulled power. Per Pobst: "The power starts to fall off significantly after the first lap. It was nearly pegging the oil temp gauge after a few laps. 320 degrees. I did a cool-off lap and it came right back down."

How can anyone call this the ultimate track Corvette if the power falls off after one lap?

Still riding that train eh? It must not make very many stops...

It's funny how you left the next paragraph out of your quote there.

I read it. You don't think 320 degree oil temps after a few hot laps is an issue for the "ultimate track Corvette"? Even Chevrolet said the auto runs even hotter.

Link? (You must have auto subscription on. )

Yes, and the next paragraph of that article states that most track day drivers will not be able to push the car to those limits.

And after reading multiple corvette forums, that I am on, with real members driving in the real world, they have encountered no issues, and lapped 90% of the track. Sure sounds like a piece of shit. You are right. I retract all my previous statements and bow to your infinite wisdom.

It was in the same article.

"That said, Corvette chief engineer Tadge Juechter recently told Corvette fans the automatic transmission runs hotter and will go into a preservation mode sooner, so he recommends the manual for serious track duty or when the ambient temperature at the track is above 86 degrees. The high ambient temperature on our test day was 70 degrees."


It's just my opinion. You can always ignore me if you don't like it.

[Camaro_Corvette]

All I'm saying is yes, I agree with you and disagree. Wait till the summer when average joe track guy can't make five laps 85+ degree weather.When several of them show symptoms of a big freaking problem, then we go on strike against Tadge and the crew with "customer" proof in hand!

But until then, spewing the same crap from the ONE car driven by the same professional driver over and over and over again doesn't mean diddly squat. The Corvette team only changes things when they see a major problem, or if it's a cheap fix. So I'm hoping that if there is a dilemma, that it hits hard in the next three months of track days. 2017 Z06 is the one to buy.

This is another reason why you don't buy a first year car.

So MotorTrend retested the Z06 after the NISMO loss. Chevrolet said the rear end was out of alignment on the Z06 they sent MotorTrend for the test.

They also softened up the suspension a bit for "rough tracks" like Willow Springs. The manual picked up 2.1 seconds properly aligned.

Randy Pobst:

Way better than it was last time! This was so much nicer to drive. Oh my gosh. The butterflies are gone. The fear is gone. There was a lot of fear in the car before. Just the handling, I trusted it way more. I still don’t experience a push anywhere. All the way around the Turn 2 carousel, it feels like I have very little steering in the car. Really balanced. Even the tail, the tail may be coming, but in a no-fear kind of way, like, wow, this thing’s really balanced!

Chevrolet also sent along an A8 for testing. All said and done, the manual Z06 ran a 1:25.00 and the automatic a 1:25.76 to the NISMO's 1:25.70.

Concerning the "high temps" of previous runs, it doesn't appear to be much of an impact.

We checked the data, and lap times and peak speeds did fall off by a few tenths of a second and 1 or 2 mph on each subsequent lap, though these could also be attributed to tire wear and other factors. Although Pobst has consistently complained of reduced engine power when lapping C7 Z06s, the problem does not appear to be especially great (in terms of lap times) and only seems to affect drivers of Pobst's incredibly high skill, suggesting that most customers won't encounter it.

Apparently that NISMO required octane booster to achieve it's advertised 600hp as 91 octane just won't cut it.

[2011shelby]

So GT-R runs octane booster.
C7 Z06 gets suspension adjustments and more than likely ECM adjustments.

They don't run the cars again same day. How can either claim a win??
