The metadata for the C7 Z06 reveal site (http://www.chevrolet.com/corvette-z06-supercar-reveal.html) leaked the engine output: 620 hp, 650 lbs*ft.

I'm disappointed but not surprised that there isn't going to be a 500-550 hp, 7k rpm or higher redline naturally aspirated engine. The automotive world just isn't going that way.

Now to wait to see what other changes are being made, and wonder aloud if it will trickle down to a Grand Sport package in a few years.

Yeah, looks like this is kind of a half Z06, half ZR-1 successor. Makes you wonder if they will be doing a 700+hp version down the line or just stick to two main levels this gen.

What do you want your dream car to have or do, Keef? Power is power, it's still going to sound the business.

As you've said, if you want to stay ALL MOTOR, stick with the Stingray.

I want an updated LS7. Direct injection 7 liter that revs to 7k rpm or more. I built one in Automation (http://automationgame.com/) based on the LT1 specs, it was glorious.

Yeah, the LS7 is still the top dog naturally aspirated V8, IMO. The AMG 6.2L (they can call it a 6.3 all they want, it's not) made similar power from a bit less displacement, but a much larger form factor and higher weight. The Ford Coyote and and BMW M3 V8 aren't in the same league, and Ferrari flat-crank V8s are a completely different animal.

The LS376/480hp is a much better $/hp kind of engine, but I would bet you that the LS7 stands up to being used hard on a regular basis. It's basically the closest thing to a LeMans engine you can get in a street car these days, especially considering the price.

Is this it? Looks pretty mental. Also appears to have an automated manual of some kinda based on the strange shifter, +/- paddles and "P" on the dash. Could just be an automatic option though.

Price and weight are my questions, because so far this thing reminds me more of a ZL1 (with an automatic) than a Z06 or ZR1.

Will be interesting to see if they make a Z28 equivalent, and what they would call it. I would probably prefer it. Either way, I'm sure this will do extremely well in comparison tests and magazine reviews.

No, Ferrari (and racing applications) use flat plane crankshafts. Crossplane is the more common road configuration.

Kchrpm
January 12th, 2014, 07:42 AM
Fun facts I just learned: crossplane is used in most road-going applications because it can greatly reduce vibration. Flatplane is used in racing because it lets the crankshaft be much lighter, therefore less inertia therefore faster to rev up and down.

It's also to do with evenly spread exhaust pulses with flat-plane cranks and the effect on tuning. The uneven firing of cross-plane cranks sounds better though IMO.;)

As an aside, I don't really get the point of putting the camo on a GT. There's not going to be a whole lot of crazy aero stuff going on due to rules, right? I get the dazzle job on the P1s, but not GT's. I liked the older testing looks of black with minor decals and/or special minimalist liveries. I'm kinda surprised we didn't see the dazzle paint on F1 like a decade ago though.

Perhaps it's purely for attention grabbing? They are using a similar pattern on the sheet covering the C7 Z06 before its unveil tomorrow.

It's starting off with a camouflaged model being hauled around Detroit as part of a C7 Corvette caravan. Not really sure why they're doing this, other than to make the reveal longer. And now they're doing a slideshow of Z06 pictures through history.

Seriously, it's just a helicopter or camera car view of the Z06 driving around Detroit with cheesy rock music playing and a cheesy announcer. It's useless fluff.

Oh wait, now that they're on the highway there is other traffic...maybe they want people's pictures of this happening to become a social media thing. Still, a stretch. Whatever. I was hoping this would be over by my meeting at 10, more likely it won't even start until then.

Edit: ~30 seconds of camouflaged Z06 video, but only the first 10 or 15 seconds replaced the caravan, then it went PIP in a corner. More cars are joining the caravan, though, seems like it's up to 30-40, with a new Caprice police car and a C7 pace car leading the way. Probably pretty impressive to see in person.

625hp, 630ft-lb. Targa with CF panel standard. The reveal didn't start until 10, all that other stuff was just filler I guess. And the reveal wasn't much, in terms of showing us the cars.

Kchrpm
January 13th, 2014, 07:23 AM
And the numbers were given with an "at least" or "more than" in front of them.

Apparently the drive through Detroit is a thing that's been done before, someone in the Jalopnik comments pointed out the Cherokee that drove through a glass wall also drove through Detroit first. They probably stream that video on the screen in the reveal area while all the journos are filing in and getting situated.

Waiting for pictures to get released, but the Z06 looks like the leaks and the C7R has a very similar paintjob. The main differences, aside from typical race car stuff (sponsors, mirrors are different colors to differentiate the cars), is a grey area extending back and down from the side vents. It's...seemingly random.

Edit: Brett posted a link to a pic on Facebook, the black on the sides looks taller than the car that was revealed I think.

Chief Engineer Tadge Juechter is doing an AMA on Jalopnik: http://jalopnik.com/ask-corvette-z06-chief-engineer-tadge-juechter-anything-1500006288

Predictably the NA question came up:

I want to know how specifically you arrived at such high power targets. Its obvious that hitting them meant ditching the NA engine for supercharged which is little saddening for LS7 fans. Was it because this was meant to be, essentially, the Z06 and ZR1?

Our original intent was to do an NA engine, we were unable to achieve all of our performance, durability, and regulatory (emissions) goals with NA. We weren't even close. You couldn't just do DI, VVT, no cylinder deactivation, 7.0 liter motor with the increase we would have wanted. New regs could have led to a horsepower decrease.
Not surprising.

Also he says that the reason the car has a torque converter automatic and not a DCT is because the "Torque converter is very important to enable cylinder deactivation, which is better than any DCT."

He later expands:

What customers really want is a very fast, very responsive transmission, and that's what we've provided. Our new internally designed 8 speed auto is far lighter than the previous 6 speed and any dct that could live behind this engine and we benchmarked the best DCTs in the world for shift speed and quality, and engineered this trans to match and better them.

novicius
January 14th, 2014, 12:20 PM
The new GM 8L90 sure seems an awful lot like the ZF 8HP90 8-speed auto -- Chrysler has their own versions that they actually build and tune in the Kokomo, IN. plant so they could technically also say that "they build 'em".


Mr. Kirk said that the partnership with ZF had been mutually productive; while Chrysler owns the intellectual property of any changes they make to the transmissions, they do keep ZF informed. Chrysler can patent any of their changes and methods, including the software and controls, and has some internal motivation to improve the transmissions and their production methods to maintain balance with ZF.
No skin off my nose, of course. I just won't be surprised if eventually it came to light that GM switched over to ZF autos. I mean, GM did put an Aisin unit in the CTS after all, it's not exactly a new move.

Instead of detuning the engine like the C4 ZR1 did (and I believe I've heard some M5s do it, as well), the 2015 Stingray's Valet Mode locks internal storage, locks out the stereo and turns on the camera and data recorder. I wonder if it will be a deterrent for all of the mechanic joy rides as well, but dealers will likely have a way of getting around them.

If the Alfa could be had with stick, it'd be a tough choice. As it is, I will take the Corvette.

I am very interested to find out how much power the new Miata makes. At 2300 lbs, it's going to be lighter than the 4C. It won't have 240 hp, but if it makes close to 200 hp it might be close enough considering it'll cost less than half what the Alfa does.

Interesting. I figured one, maybe two would be plenty.

When I was driving my dads C7 last weekend, I found that 7 gear was useless. In Eco mode, you actually get better mileage in 6th/V4 mode at highway speeds (up to 80 at least I saw). It can hardly even stay in V4 mode around 70 In 7th. If you're in a V8 only mode, 7th was a little better at those speeds, but again if you really want to save gas, put it in Eco and use 4 cylinders in 6th gear.

There is probably a specific time where everything is useful. With all the controls on modern drivetrains you really have the option of accounting for every possible scenario. Hammering on that rental Corolla last weekend I observed all sorts of seemingly pointless combinations of engine+transmission that I'm sure exist electronically for just one specific scenario - eg, cruising through Kansas at 75mph with a slight tailwind vs. cruising through Nebraska at 75mph with a slight headwind. ;) (The Corolla could do 85mph at 2000rpm on a flat surface, which I found stunning for a 1.8l)

Has anyone been listening to this stuff about heat soak and the ECU pulling timing on the Z06?

http://www.autoevolution.com/news/2015-corvette-z06-owners-report-heat-soak-power-loss-its-actually-a-conservative-ecu-setup-89790.html


Now that the 2016 Corvette Z06 has hit the streets, sucking our air through its blower, a few owners have complained about experiencing a power loss after back to back runs on the highway or multiple laps on the track. They rushed to point the heat soak finger at the LT4 motor in the Z06, but this doesn’t seem to be the culprit here.

Sure, as the Z06 uses a top-mounted charging hardware, you could expect it to be prone to heat soak issues. When this issue usually appears, after a few consecutive full throttle runs, the heat builds up in the engine compartment, resulting in the a temperature increase for the air charge. This dramatically reduces supercharging efficiency as hot air has reduced oxygen molecule density, allowing for less fuel to be burned.

Moreover, hot intake air charge also increases the risk of detonation. The computer measures the intake air temperature both before and after the charge and when the latter is too high, it starts pulling timing to protect the engine.

However, like we said, this isn’t an issue with the LT4 supercharged V8 in the 2015 Z06, or at least that’s what the tuning scene is reporting.

Aftermarket world explains this is all a conservative ECU setup

Pulling power? Track/WX Conditions? Gearing (maybe they used the 8AT with what I think is longer gearing)? One extra shift if manual? Roll-out vs. no roll out? Maybe they used launch control, which I think I heard actually sucks on the Vette? Certainly seems off.

I'd love to see the splits in that test, or better a graph, like R&T does with acceleration.

Where did you find that number? The only listing for 0-150 I could find was 14.4, listed here: http://www.automobile-catalog.com/car/2015/2036990/chevrolet_corvette_z06_coupe_7-speed.html , though I don't really trust that too much. Is the 0-100 really 6.5?

They also have a test sheet for a manual car that the tester felt was underperforming: http://media.caranddriver.com/files/2015-chevrolet-corvette-z06-manual.pdf

Keep in mind, though, that the new Z06, especially in stage 3 trim, has much more aerodynamic downforce than the C6 Z06 and could therefore be much less slippery at high speeds.

Posted on another forum. The aero is probably a big factor but there are some heat/ECU-related issues too. At the moment they don't really know whether is true heat soak from the smaller 1.7L blower or just that the ECU is overly conservative and pulls too much timing when IAT rises significantly.

A lot of people are extremely disappointed by that answer and don't really understand why the ECU needs to be so conservative unless there's a real heat issue. There's also a major problem with having to void your warranty to use the car's stated factory hp consistently.

One of the car magazines blew the engine in the Stingray they had for a long term test, too. It was deemed to have been caused by a bad oil filter, I believe, wonder if this is similar. Hopefully these kinds of things are incredibly rare, I'm assuming this new small block will see heavy use at General Motors.

Those that caught my writeup of the Stingray's new eight-speed automatic transmission this summer won't be surprised to read it, but the gem of the track day for me was a Z07-pack car with the autobox. No shit.

Here's the formula: select Track for drive mode, Race for traction management, and then slot the automatic's lever in straight D and ignore the shift paddles on the steering wheel. All of my fastest times turned that day were all with the configuration above. Thusly set, the Z06 does a kind of wonderful Nissan GT-R impression: shifting and gripping and going like a virtual racer straight from Forza, but with far more tactility and progressive handling up to the limit than I've ever felt behind the wheel of Godzilla.

From the very next paragraph:


The eight-speed isn't nearly so satisfying when shifting in manual mode, and, honestly, I still preferred the rev-matching seven-speed hand-shaker despite it being slower to use. If it were my Corvette to build, and even if I planned to track it regularly, I'd opt into the sweet manual with its easy clutch and clean, short throws.

http://i466.photobucket.com/albums/rr29/ynotdv8/2014%20Viper%20TA/Dyno%20Testing/DSC00518.jpg


After we unveiled the first video, showing the races between the 2015 Z06 and the 2014 Viper, people requested that we get both cars to a Dyno. We arranged this long testing session through KP Racing, in Houston TX ( http://www.kpracing.com ), and used their load-based Mustang Dyno. All results are being compared with SAE correction factor, which is labeled with “WCF” for “with correction factor”, on the images. We were able to log data on two of the main vehicles, and also collected data from another C7Z06 that dynoed last week. For good measure, we also brought along a 2nd stock 2013 Viper GTS. So, we had these vehicles to compare from:

-2013 Viper GTS (100% stock) 7,000 miles
-2014 Viper TA (100% stock) 2,300 miles
-2015 Corvette Z06 (100% stock) 1,200 miles
-2015 Corvette Z06/Z07 (100% stock) 100 miles (previously dyno tested, last week)

We were primarily testing the two vehicles that raced in the video last week, and using the other two vehicles as back-up for data comparisons. Temperature data was recorded for the white Viper TA, and the black C7Z06, before and after runs. Neither car had a complete cool-down period, both were tested at normal operating temperatures, with ambient temperatures in the mid-50F range. These are the results that matter, as cars at operating temp are what would match up with each other on the track or highway. The Viper TA did one warm-up dyno to reach operating temp, as we’ve seen previous cars pick up power once they get hot. This proved to be true, as the cool Viper TA was also the worst dyno result posted.

Each car was then tested with a barrage of 4 back-to-back dyno pulls. We monitored Intake Air Temp (IAT) before and after runs. We also monitored all sorts of parameters on the C7Z06, via HP Tuners logging software. These 4 consecutive dyno pulls were done without turning the engine off, with approx 1 minute of idling prior to making the next consecutive pull. We wanted to see if heat soak affected either car, by doing so. We also shot various parts of the engine bay with a laser temperature scanner, to monitor external temps on both cars.

We found that neither car appeared to be affected by heat, even after 4 consecutive pulls. Both cars produced more than their factory rated hp (640 Viper, 650 Z06) even when at full operating temperature, and after the 4th dyno run. The Viper TA produced its best results on the 3rd consecutive dyno pull, 540 rwhp & 512 ft-lbs torque (SAE corrected). It only lost 0.5 hp on the final consecutive pull. The C7Z06 produced its highest dyno on the 2nd consecutive pull, 563 rwhp & 562 ft-lbs torque (SAE corrected). The C7Z06 only lost 4 rwhp by the time its final pull was completed. Negligible loss, for both cars.

This data was then compared with each vehicle, as well as with the other two test sample vehicles (Viper GTS, and other C7Z06 from a week earlier). We found these comparisons:

1. Both C7Z06’s produced nearly identical results, at operating temp. Within 1 rwhp.
2. The Viper TA at operating temp, is a close comparison with the C7Z06 at operating temp.
3. C7Z06 produces about 15-20 rwhp more than the Viper TA, when both are at operating temp.
4. Torque output on the C7Z06 is outstanding. But, at the lower rpm range, it has no effect on racing. Driving around however, it should feel very responsive and fun. This will make the car “feel” faster to most, as reported by many.
5. The Viper GTS with 7000 miles produced a slightly stronger (7 rwhp) result than the Viper TA with 2300 miles.

Since it was cool outside, both cars showed interesting temperatures at the intake manifold, after the four runs. The Viper intake manifold actually got colder by 12F after the pulls. The Z06 was still impressive though, the supercharger housing (intake manifold) only increased 1 degree, after 4 consecutive pulls. Both good, in that regard. The IAT values were another story. The Viper increased in measured Air Intake Temp by 13F. The Z06 did much better, with both IAT1 (pre-blower) and IAT2 (post-blower) both reducing after the 4 consecutive runs. GM did a great job on the cooling efficiency on this blower. But, the true test will be seeing how they perform when it is hot outside.

Coolant and engine temps were also interesting to compare. The Viper only picked up 1 degree on the coolant temperature. The Z06 picked up 19 degrees, still respectable. This could translate to lap times on long sessions, as it seems the Viper cooling system is super efficient. Oil temps for both cars were similar gains, 20 Viper and 25 Z06.

True. I think it's more a case of people trying to straighten out the stories of heat-soak and figure out why the Viper is slightly faster over the quarter despite having less power and torque but the results don't really answer that. It's also interesting to see that the lighter C6 ZR1 is still faster and maybe the next ZR1 will be mid-engined!! I note there's already 1500hp kits out for the C7 Z06.:D

Out of all of them I'd probably take the Hellcat even though it's the slowest and I can't even explain why.

So get this: The new Corvette Z06 turned an absolutely blistering 2:41.3 at Virginia International Raceway (VIR), and the company has released a video of the lap recorded using the car’s awesome Performance Data Recorder. That time is really damn quick—and we should know, as we run our annual Lightning Lap competition at that track using the same highly technical, 4.1-mile Grand West Course layout as Chevy did for this lap. Watch the clip below, and then read on for some more perspective, as well as insight into the lap from C/D technical editor K.C. Colwell, who has laid down a number of our times at VIR, including the overall record.

We’ve run Lightning Lap eight times now, amassing more than 160 times for performance cars that run the gamut from the impish Ford Fiesta ST all the way to exotics from Ferrari, Lamborghini, and more. In fact, that overall record was set this year in Porsche’s scintillating 918 Spyder hypercar with a 2:43.1 time.

So does the Z06’s 2:41.3 mean that it’s quicker than the 918? Well, no, not really. The Z06 scorcher—4.3 seconds quicker than GM’s time at the track for the C6 ZR1—was laid down by engineer Jim Mero, one of the Corvette program’s hottest shoes, and someone who has perhaps spent more time thrashing the 2015 Z06 than anyone else on the planet. Chevrolet also no doubt spent several hours, if not days, at VIR doing development work in concert with achieving the lap. In contrast, our editors’ first time lapping a performance car in anger often occurs during the Lightning Lap competition itself, and time restrictions—we often have more than two dozen cars to assess in a three-day window—generally mean that we only get 15 to 20 laps to record our top times.

Motor Trend Z06 test.

http://www.motortrend.com/roadtests/coupes/1504_2015_chevrolet_corvette_z06_vs_2015_nissan_gt _r_nismo_comparison/track_performance.html


When we overlaid the plots of the Z06 and GT-R’s best laps, we all sat back, briefly confused. Is the Nissan really that much faster at higher speeds? Does the Corvette really outgrip the GT-R that substantially through the long Turn 2? The data doesn’t lie. (We simultaneously record these laps with two different Vbox data loggers precisely to keep them honest.) But on both the front and back straights, the Nissan clearly had the legs on the Chevrolet. Gearing? Aerodynamics? Heat buildup? Meanwhile, the Corvette’s big Turn 2 cornering edge quickly degraded during subsequent laps. Was heat generation in its tires rocketing their pressures? And notice, too, Randy Pobst’s pause between Turns 4 and 5 in the Z06 (avoiding a time-eating gear shift) and his dramatically early braking before Turn 9 due to a lack of total confidence. Often comparison lapping days such as these leave us frustratingly short on time to unravel all the underlying puzzles. But we know for sure that despite all the back and forth in the speed graph, the GT-R quickly grabbed a small lead on the Corvette and held it all the way to its 280-foot advantage at the finish line.

It seems like they're thinking the aerodynamic efficiency (downforce vs drag) of the GTR's wings vs the Z06s spoiler+wickerbill is one of the culprits. Pobst mentions that the GTR makes better downforce on the long high speed turn leading onto the front straight, and they tried some laps without the wickberbill on the Z06, but the new straightline speed didn't make up for the loss of rear traction.

But you still can't discount all those computers doing excellent work for you in the GTR driveline, it was launching harder out of every turn.

Yeah AWD is a really big advantage, the 918 has kind of proved that against the P1 at Laguna Seca (see May's issue of MT). To cut a long story short, the 918 allegedly won by 0.8s and both cars beat the current 1:30.97 lap record.

One of the mundane things I miss about the Vette is how far I could go on a single tank. I really get annoyed with the Mazda when it's at a quarter tank with only low 200s on the trip. I went on a road trip shortly after getting the Mazda and was really excited that I got 300+ miles out of a tank pretty easily, but that has proven to be the exception, not the rule. It just doesn't have the day-to-day fuel economy to make up for the little tank (filling up from below a quarter tank is usually 11-12 gallons).

Compared to the Vette, which at its worst got 368 miles (from 14.7 gallons), and had a best of 420 miles (from 16 gallons). I'm sure that would drop during a normal commute cycle, but still.

Bwright asked:

You mentioned in this week's answer to the Ask Tadge question on overheating that there are, "Lots of interesting back stories behind recent media tests." In light of that, what are your thoughts on the recent Motor Trend test of the new Z06 vs. the GT-R Nismo at Willow Springs? Any interesting back stories on that or any other recent media tests?
Quote:

Tadge answered:

To be perfectly honest, both Chevrolet and Motor Trend were surprised by the test results - both the lap times achieved and the subjective comments on handling which did not match their impressions from the first drive story at Road Atlanta. Obviously the GT-R Nismo is s supremely capable machine engineered for precisely this kind of track work, so nothing against them, but we thought we would do better. After the story was published, we decided to examine that car closely and do a follow up test at Willow Springs.

We first discovered an alignment setting error in the rear. We knew something was wrong with their test car because of Randy's oversteer comments. In the words of our development engineer, Jim Mero, "The car is tuned for a small amount of understeer, but we found out the rear caster was inadvertently set to 2 degrees instead of 0 degrees. This causes ride and roll oversteer". We try to keep the Corvettes used for media tests in perfect condition, but didn't this time, and the alignment clearly had an effect on handling and driver confidence.

We also learned the Nissan was using octane booster, as it will cut power when running the 91 octane pump fuel available locally. Generally speaking, higher octane enables more aggressive spark calibration and higher power. While the Z06 is certified for 91 octane fuel, adding octane boost will offer greater resistance to spark retard and detonation under thermally challenging conditions (reduced likelihood of power reduction when intake temps go up). Racing fuel (100 octane) available at the track improves this robustness even further. We will be recommending that customers who track their car, especially at higher temps, use the highest octane fuel available.

Although we do track testing at quite a number of tracks around the country, we never tested at Willow Springs, so we decided to rent the track and check the performance of the Z06 ourselves. We looked at it as an opportunity to learn something. What Randy told us and we confirmed is that the track has an unusual combination of speed and roughness.

We used exactly the same car Motor Trend tested, as well as a second car, an 8 speed automatic. With proper suspension alignment, we saw a marked improvement in handling.

We also used the opportunity to tweak the calibration of the magnetic ride dampers in Track mode (Tour and Sport modes unchanged), and were able to improve the vehicle’s dynamic behavior. Since we think that calibration is uniquely suited to very rough tracks, our plan is to offer it through our Performance Parts department for customers who frequent those types of venues. So it was a good exercise for us.

We invited Motor Trend to test the car again with suspension alignments corrected and give us feedback on the new calibration. They are planning a follow up article based on Randy's experience, and since we don't want to "scoop" their story I won’t say specifically what the results were. However, I can say we were very satisfied. Look for it soon!

Why would they use octane booster in the GT-R but not the Z06? Maybe the GT-R is rated to use 92 or 93, but they could only get 91, and the Z06 is marked as 91 so they just left it.

As a result of this new testing at Spring Mountain and additional testing at Willow Springs, Chevrolet developed a new Rough Track mode for the Z06 that softens the dampers in Track mode. Chevrolet plans to make this software update to the Z06 available soon through the GM Performance Parts catalog, and our test cars at this retest were both fitted with the new software. We cannot say, then, that the improvement in lap time was due solely to the corrected rear alignment, as it's possible the new damper programming also aided the Z06's performance.

.
.
.
.

Regardless, the results are clear. When properly aligned and using a softer damper calibration, the Corvette Z06 is as fast as or faster than the GT-R NISMO at Willow Springs. 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.

The high ambient temperature on our test day was 70 degrees.

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."

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.

Handling is where we expected to see the biggest difference, but it came in the driving experience rather than in the numbers. The numbers say this automatic Z06 matched the manual cars' best performance on the skidpad in pulling 1.17g average. In our figure-eight test, it was actually the slowest Z06 yet tested by a tick, putting down a 22.6-second lap time at 1.01 g average. It was, however, incredibly consistent in its figure-eight lap times, something that can't be said for the car with the alignment problem, which also happened to be the car that posted the quickest Z06 lap. We're beginning to suspect that 22.3-second lap was a perfect lap, as the other cars have consistently been in the 22.5-22.7-second range. Regardless, anything under 23 seconds is screaming quick and among the fastest we've ever tested.

In addition to the consistency in figure-eight lap time, the big difference was in how the car drove. The chassis was far better balanced and neutral with no obvious tendency to under- or oversteer at corner entry or mid-corner. Aggressive throttle input can provoke a power oversteer at exit, but it's predictable, smooth, and easily controlled with quick hands. It was a welcome improvement from the badly aligned car, which would pop loose at turn-in and have to be managed all through the corner. With this car, you brake late, turn in, go to maintenance throttle, and power out judiciously, just like every driving instructor has ever taught you, and the car responds exactly as it's supposed to. Given the myriad computer aids available on this car, we tried lapping it both in Manual and Automatic modes, as well as with and without the Performance Traction Management (PTM) and its Track mode. The lap times were essentially the same, though we found it more fun to shift manually and to disable the PTM entirely, as we found the crutch encouraged sloppy throttle application (though with enough practice, it could be a handy aid in the right hands). We also found the automatic transmission to be geared shorter than the manual. Whereas the manual car could complete a figure-eight lap in second gear only, the automatic needed to get to third. Left to its own devices, the transmission was fine, but we found in manual mode it could be a bit slow to react to the paddles when a downshift was requested. Adjourning to the race track, we found the automatic Z06 a compelling performer at Willow Springs International Raceway's Big Track. With a proper alignment and Rough Track mode, it lapped the "Fastest Road in the West" in 1:25.76, 0.06 second slower than the Nissan GT-R NISMO and 0.7 second slower than a properly sorted manual transmission Z06. Given that Randy Pobst lapped this automatic Z06 first and the properly sorted manual Z06 second, we believe he may have been able to come closer to the manual car's time or even match it if we had more track time, based on his increased familiarity with and confidence in the car.

"This car is far better than the last one we drove here," Pobst said. "It's putting power down far better than it did last time. The traction under acceleration is far better. This time, I had the confidence to have a sense of downforce in the fast corners, especially 8 and 9, that the car was kinda hooked." He added: "The car is still, in my opinion, a little bit oversteer-y. It should be, in my opinion, a little bit understeer-y, especially so you can keep your foot in it when you're going around a corner -- you can use more power -- so it doesn't go to oversteer as quickly." Even still: "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!' " With regard to the automatic transmission, he was generally positive. "The automatic is really easy," he said. "It makes it so easy. Except on the first two laps, it got lazy on the three-four shift coming out of 9. Drove me crazy, but then it went away. It was on full automatic, and it hung on the redline. It just hung there, then it shifted. It felt like forever. I was driving slower on the out lap to protect the tires, so the transmission said, 'Oh, you're not going flat. I'm gonna shift up.' Maybe that's what confused it, but it did it the second lap, too, which was hot. The third lap it didn't do it, though. But maybe that's why. It took the transmission awhile to realize 'I'm at a racetrack.' It's pretty sweet, other than that. Man, it works great."

There was still a matter of engine oil temperature, though, which plagued the other Z06s we've tested. Per Pobst, the oil temperature nearly redlined after a few laps, topping out at more than 320 degrees. Taking a cool-down lap brought the temperature back down, and the car was good to go again, but that's not ideal. Moreover, he reported "the power still falls off significantly after the first lap" after the engine gets hot. 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.

C7 Corvette Cracked Tires Problem Explained by Michelin Engineer - autoevolution (http://www.autoevolution.com/news/c7-corvette-cracked-tires-problem-explained-by-michelin-engineer-93114.html)

http://i1281.photobucket.com/albums/a508/sigmafour1/cracked%20Cup%202_zpsqg5br7nr.png (http://s1281.photobucket.com/user/sigmafour1/media/cracked%20Cup%202_zpsqg5br7nr.png.html)


It’s been only a week since CorvetteForum.com member sdtoothdoc uploaded photographs of his 2015 Corvette Z06 wearing cracked tires all-round. Following this rather disappointing state of the Michelin Pilot Super Sport ZP / SC2 tires, a Michelin official cleared the matter up for CorvetteForum.

In the original forum thread, sdtoothdoc says that “my A8 Z finally got here in San Diego and took her home a few miles away. As suspected, all 4 tires have cracks like Dennis's from Las Vegas. When at the dealer, they said that 4 other Stingrays all have the same cracks in the tires. Car looks amazing otherwise!” What can we learn from this? It’s not an isolated case...

Considering that a new set of high-performance Michelin rubber costs more than $2,000, both C7 Corvette owners and enthusiasts wondered if dealers will replace the damaged tires free of charge. Fortunately though, Michelin’s lead engineer for the C7 Corvette Lee Willard issued the following statement to CorvetteForum.com:

“This winter has been extremely harsh in much of the country and some recently shipped Corvette tires may exhibit cracking. In general, summer tires should never be driven on or moved in temperatures under 20°F because they may crack. Tires should be carefully inspected at the dealership before taking delivery of a vehicle.” declared Willard.

“Never use a tire with freeze cracks, breaks, or damage to the sidewall or tread. For those residing in colder climates, Corvette owners should have a plan for vehicle storage during cold winter months. If your garage drops below 20°F regularly, consider removing tires and storing them inside. If you live in colder climates and want to drive your vehicle in temperatures below 40°F we strongly recommend investing in a set of winter or all-season tires.” he added.

As things stand now, Michelin is right - it’s not their fault that the tires on brand spanking new C7 Corvette Stingrays and Z06s were cracked, but General Motors'. It’s the carmaker’s duty to ship new cars from assembly plant to dealer in perfect conditions, including temperature. Let’s keep those fingers crossed General Motors will man up and replace the cracked tires at no cost to the owners in the near future.

From Motor Trend mag


Chevy Corvette Z06 (Z07) DNF

"Spark retarded by 8 degrees."

"GM claims it was an issue of being confused by California 91 octane fuel"


CHEVROLET CORVETTE Z06 (Z07)

Chevrolet Lets Itself Down

It didn't work. The damn Z06 retarded spark by 8 degrees, and the 1.7-liter TVS supercharger refused to make boost. Chevrolet came up with a "bad gas" theory, but Big Nasty got filled at the same Chevron stations as everyone else and even swallowed 8 gallons of 101 octane to wake the supercharger. No luck. What we have here is a failure to compete. What a pity.

Have a look at the specs: 650 hp; 650 lb-ft of torque; big, brawny Brembos; 15.5-inch carbon-ceramic rotors with six-piston monobloc calipers up front, 15.3-inch carbonceramic rotors with four-piston monobloc calipers on the rear; relatively light weight due to its stiff aluminum chassis; and in Stage III Aero guise, the Z07 package records lateral acceleration of 1.17 g, thanks in part to the sticky Michelin Pilot Sport Cup 2 tires (285/30R19 front; 335/25R20 rear). If any car could dominate Mazda Raceway Laguna Seca, it's this Chevy. This is the horse you bet to win.

If any car could dominate Mazda Raceway Laguna Seca, its this Corvette Z06.

1:38.60. That time is the best lap our sick Z06 managed to squeak out. Here's a list of cars from this year's BDC the broken Z06 was able to limp around Laguna quicker than: Mazda Miata, Volkswagen Golf R, Bentley GT3-R, Lexus RC F, both Cadillac ATS-Vs (a manual and an automatic), and Mercedes-AMG C63 S. Also, the totally healthy Cadillac CTS-V managed to just pip the lame Z06 by 8 hundredths of a second.

Those bested competitors are just from this years group. Dig into the history books and you'll see the busted 'Vette was also quicker than an Audi V10 Plus (1:38.70), Shelby GT500 (1:38.70), Mercedes-Benz SLS AMG (1:38.82), Mercedes-Benz C63 AMG Black Series (1:38.90), Porsche 911 Carrera 4S (1:39.19), and a Chevy Camaro ZL1 (1:39.20). Chevy fans can take solace in the fact that even when wounded, the Z06 is quicker than most other high-performance machines. But can you imagine what time a working Z06 would lay down? Remember, the ZR1 managed 1:33.70. Sigh.

From MacKenzie: Kudos to GM for always manning up and putting its cars forward for the most grueling performance test in the business. So it was disappointing to see Big Nasty sidelined by a mysterious engine problem not even the GM techs on hand could figure out. And disappointing to also discover that a car supposedly specially earmarked for BDC testing had been sent to us with worn-out brake pads. Oh yeah, the brake pads were in terrible shape. Had the Z06 been making full boost, one of us might have been in big trouble on 198.

Chevy is now thinking that California's 91 octane confused the computer when it mixed with 93 octane from Arizona. I say that's bogus because not only is California the Z06s largest market and our 'premium' fuel a known quantity, but you're going to tell me this is what will happen to skinflint owners who try to save a buck or two by filling their Z06s with midgrade fuel? That, and this entire ordeal, is unacceptable.

FWIW, in this year's Car and Driver Lightning Lap at Virginia International Raceway, the Z06 set the second fastest C&D LL lap time ever of 2:44.6, bested only by last year's 918 Spyder, which did a lap in 2:43.1

Both cars are capable of more with professional setup and drivers, but those are journalist lap times.

Doing some more looking, they do use the Grand West course (the track maps I posted were from the Grand East).

Going back to the source, C&D, the track did change, but not in a way that would really show up in the track maps we're looking at. Here's their breakdown.

http://media.caranddriver.com/images/media/640860/vir-course-inline1-2-photo-642669-s-original.jpg


Changes, The Remix
VIR is in the midst of some major renovations—most planned, one not (R.I.P. oak tree). This past winter, the owners repaved the Full Course (the track’s marquee outer ring) to make it more suitable for top-tier racing. In so doing, they widened some sections (shown in light blue above) to encourage overtaking, including Turns One, Three, 12, the straight between Snake and the Climbing Esses, and the exit of Turn 10. The wider corners made the track quicker. But we’re not Major League Baseball; you won’t see any asterisks on our lap times. Tracks change.

How much of that 6 seconds goes to the track changes? No good way to tell. They only re-test cars when there has been a significant model change, so looking at lap times from different years doesn't really work.

These are some of the cars from 2014 and 2015 tests that it is faster than, though, on the same version of the track:
2014
Nissan GT-R NISMO - 2:49.4
SRT Viper TA - 2:49.9
Ferrari F12berlinetta - 2:50.8
Porsche 911 Turbo S - 2:51.2

2015
Porsche 911 GT3 – 2:50.4
Mercedes-AMG GT S – 2:51.0
McLaren 650S Spider – 2:45.8

Turns out the issue at Motor Trend's test wasn't the fuel, but that an electrical connector for the intercooler pump wasn't fully seated. It was the same car that was used for the VIR test, where Car & Driver slid it into a tire wall, necessitating some minor fixes.

http://jalopnik.com/why-the-corvette-z06-flunked-motor-trends-big-performan-1736976325

This also leads to some info on why owner's cars have been overheating: improperly bled intercoolers.


One of our pre-loan checks is to bleed the intercooler circuit to make sure there is no air in it. Some customer complaints about over heating Z06s have been traced to improperly bled intercoolers. The technician doing the work plugged in the electrical connector for the intercooler pump and it seemed to seat and “click” into position, but the secondary latching mechanism did not fully lock into position leading to intermittent operation. Without the pump running there is no coolant flow, no intake charge cooling and the engine pulls spark to protect itself.

That is what Motor Trend experienced at random times during their testing. Unfortunately, the connector was seated enough that the pump and engine worked fine in all the pre-test driving done before trucking the car across the country to Motor Trend in California. Remember this is the same car that performed flawlessly a few weeks prior in sweltering heat during Car and Driver’s Lightning Lap. The possibility of bad fuel was discussed because it was clear there was an abundant amount of spark retard, but we didn’t discover the true root cause until the car had returned to the Milford Proving Grounds after the test. We have modified our procedure to run the pump remotely during the bleed process so this issue can be avoided in the future.

Yay forced induction! :|

October 17th, 2015, 03:14 PM
More like "yay bad connector designs" or "yay bad technicians." Blaming forced induction is like blaming electric fuel pump. Hey, they have connectors that can become unseated too. But they don't for some weird reason. The Jag has an electric intercooler pump... you know how many times I've heard about one becoming unplugged? Zero.

But if a 7 Liter version of the LT1 comes out, making 500+ hp, ALL BETS (and plans) ARE OFF!!! ;)

Honestly. If you just keep waiting for the next best thing you'll never be able to get the experience. Just keep your plan and buy what you can in 2018. Enjoy it for a few years and then if something else comes out you can sell and upgrade.

I am not purposefully waiting for the next big thing, but I am gun shy of making payments on something 10+ years old, and Chevrolet consistently makes improvements that I find really appealing (except with their forced induction cars). If I just liked Corvettes because they were sleek and fast, that'd be one thing, but I love all the tech and improvements they throw at it (magnetic shocks! multicolor HUD! customizable dash! multiple USB ports! rear view camera! rev match!), and most of it is stuff that's not simple to retrofit on an older model.

But if the Grand Sport is just new body panels and wider tires, that's easy enough to replicate later, and if the C8 is a supercharged 5 liter, I'll be C7 fo lyfe. There's a method to my madness!

(I remember when people made fun of me for being somewhat disillusioned on the C5 Z06 when the C6 came out, but I *always* thought the C5 Z06's short rear glass was ugly and only existed to make them visually different)

(and the only reason I'm not already driving a C7 is the replacement of the Altima with the Mazda; I had figured out how to swing a C7 by July of last year, and then the Altima started its walk down death row)

And yet you don't have a c6z.....

I almost had a normal C6, but found out it had already been in 2 or 3 accidents and gone through 7 owners in 5 years, IIRC. Something crazy like that. It was instead purchased by a local body shop owner, which I found out when I went to the dealership to give them a low ball offer.

More on point, though, C6 Z06s do not cost substantially less than a C7 unless you start getting into the ones with a lot of miles. As a person that doesn't trust himself to do home mechanic maintenance, and has already owned two cars that just went sickly on me due to mileage/age with no simple fix, I don't really want to go after a 2006.

Quick check on Autotrader: the cheapest C6 Z06 within 100 miles of me is $36,990 for a 2007 with 45,000 mile; but if I want something that won't be 10 years old at the end of the 5 year loan, that's $51,988 for 2012 with ~13k miles. That's a big difference in price. There are manual C7s below that price, and with the options I want (MR, HUD, Z51) they are nearly the same.

I know this sounds weird to someone who bought a Porsche knowing he was going to have to take the engine out and make a major repair, but I have ZERO interest in doing something like that, especially on a car I'm paying $600/month for with little to no trust or experience in my mechanical skills.

The C6 was still a "awesome, but..." car when it came to the interior and especially the seats.

The C7 is not an "awesome, but..." car. It's awesome, period. Better things might come along but there is absolutely nothing about that car to feel like you compromised.

A plain ol' C7 Stingray Z51 is absolutely a car I'd consider purchasing myself after the Challenger is paid off.

I really want the red , white, and blue Honda Africa twin but fuck waiting for next years model. I can go to a paint shop and get one of the guys to wrap the parts for me. Or switch with someone. Or just buy them outright.

Next years bike might have cruise control and other amenities, but i'm not waiting.

But I hear you, your plan is sound. I say this as I drive a 21 year old Mercedes with 208K miles and no payments. Not quite your Mazda situation.

I am continually thinking about selling the 911 to dump my payment and pay off the student loan. But I figure if I invest enough money into it, I won't be able to justify selling it.

2017 Chevrolet Corvette Grand Sport deets (http://www.autoblog.com/2016/03/01/2017-chevy-corvette-grand-sport-geneva/?ncid=edlinkusauto00000016).

Did Chevy fix the issues with the Z06? 'Cause this thing sounds way more appealing for track days. :up:

As discussed previously, the problem seemed to be improperly bled intercoolers. I haven't heard that they've done anything to make that setup more reliable/robust.

But it does look like an LT1-powered Z06, and I am a fan :up: But it doesn't change my Z51 plans, at least not with just press pictures of that color combo. It does hopefully give me a new A-Class car for Forza 6, though.

It seems hard to believe that Chevy won't address that issue at least in future sales. :smh:

Put me down for a '17 Grand Sport -- with the optional eight-speed automatic, of course! :lol: #bangbang

I'll be curious how they do, if there's a design change or just a reminder of how to properly bleed the intercooler.

Ah re-reading your posts I see that it's not really a bad problem -- just make sure the electric intercooler pump is plugged in and working. :up: #carryon

Pointing out some of the details, like red taillights on the widebody (the Z06's are clear), body color rear intakes (black on the Z06), split side vent and unique wheels.

I just remembered that the stock C7 is already pushing the boundaries of my narrow garage entrance, the wider shoulder and hips of the GS would likely be an issue. I *think* I'll be folding the driver's side mirror in already just to give myself some breathing room!

Now give that a 7.0L engine, that would seal the deal.

Chevy's page for the Grand Sport has a more traditional GS paintjob. I'm a fan :up:
