"Wide open throttle second-to-third upshifts are 0.08 seconds quicker than those of its benchmark, Porsche’s seven-speed PDK, says Kaveh (0.45 vs. 0.53). Downshifts from WOT at 60 mph in Sport mode are just as quick (0.95 seconds) too. The PDK also nips at the Hydra-Matic’s heels during WOT first-to-second upshifts (0.49 vs. 0.52)."
"To experience the gearbox’s character, Chevrolet set us loose on its 2.9-mile twisty, undulating, blind-corner-filled track at the Milford Proving Grounds. Nil-to-wee sprints in Track mode, automatic shifts, were quite telling: The gearbox knocked off gears at its indicated 6500 rpm abruptly, spectacularly, with an accompanying violent explosion that only a 6.2-liter V-8 with quad pipes could produce. As corners neared, downshifts were again crisp. Deep inside corners, gears held with no moments of confusion or hesitation — it was as if the CPU was more intuitive than reactive; more organic than robotic — which ballooned my confidence and allowed me to pinpoint the longish nose."
"While Chevy’s numbers beg to differ, the 8L90 in Track mode simply didn't feel as quick as the PDK when operated via its plastic paddles. Don’t get me wrong, clicking off a WOT upshift is a glorious, stupidly fast affair. It is much the same for downshifts. Yet, Porsche, with its well-honed cohesion of an extra clutch and different structural packaging, still has the upper hand in smoothness and feel while on track. Even still, the 8L90 was impressive, especially when off the track. We drove more than 40 miles in highway and city settings around Milford. Smoothness was the name of its game. Intuitiveness was too. Multi-step highway passes in automatic mode required no pauses on its part. The ‘Vette just flew. Then it calmly upshifted into a gear best suited for casual cruising. "

"We only caught the new transmission hunting once in about 12 laps on the difficult course, and that could have been our fault with sloppy pedal work -- feathering the gas when we should be flooring it, or the other way around. It is a little unsettling seeing the shift lights on the dash flashing, which means “shift,” while and transmission just hangs in gear and the exhaust wails at full rpm.Once your driving has settled down off the track, the eight-speed automatically adjusts back into “street mode.”After driving three high-powered cars with eight-speed, torque-converter automatics (Challenger SRT Hellcat, Jaguar F-Type R and now the Corvette), we can say the newest models are every bit as good as the dual-clutch setups. They can shift as fast, feel smoother and aren’t rough on low-speed launches like many of the performance-oriented DCTs on the market, giving you all of the advantages and none of the disadvantages."
Here is another review from Autoblog:
http://www.autoblog.com/2014/08/20/2...ew-quick-spin/
http://www.autoguide.com/manufacture...view-4080.html
"To begin my first lap, I did what any red-blooded car lover would do when given the keys to a brand new Corvette; I mashed the accelerator pedal. Instantly the car leapt forward in a V8 snarling furry. There is no hesitation or torque converter delay with the new eight-speed automatic – just instant response. As I accelerated toward the first corner at well over 100 MPH, upshifts were firing off lightning quick, just as advertised.
As I approached the first corner, standing on the brakes, the engine begins to do near redline, rev-matching downshifts. True I’m running in “Track” mode, but there is no other input from me. The car just acts like it’s supposed to on a track, firing through the gears as needed. I run another five shaky laps trying to figure out the undulating, challenging course. During this time I’m anything but smooth, but the transmission is only caught out in the wrong gear twice and both times for less than a second.
Needless to say the new eight-speed automatic works at the track, but this should come with a caveat – don’t touch the paddles. The software engineering has been so well sorted out that the computer is calling for gears in advance to the driver actually needing them, so when the change occurs it’s at the exact right moment. Since this is a “regular” automatic, using the paddle shifters to “manually” select a gear is followed by a lengthy delay.
It’s the one thing a conventional automatic cannot match compared to a dual clutch transmission (DCT), the response time from a driver’s input to the physical gear change. Sure the new eight-speed can change gears lightning quick, but a DCT has already pre-loaded the next gear and can react to a new input much faster. I will say that response time does feel quicker from the Corvette’s eight-speed automatic than the eight-speed autos I’ve recently sampled, including in the Jaguar F-Type."

Here is the YouTube video of Manoli Katakis driving the Stingray with the A8 in Drive Mode. This video has been discussed. But the question remained......
Q. But Manoli what about the manual paddle shift mode?
A. Manoli Katakis responds:
"Not for this recorded run. For the sake of the demonstration, I wanted to show how well the transmission thought on its own. I did use the paddles on an earlier run. It was more fun, and incredibly sharp."

Yep!! Cant wait to see the performance numbers released!
You pull (or push) a paddle mounted behind the steering wheel to shift up (or down) a gear.

The computer is faster and more accurate than you... It shifts very well in auto for the A6, and should be even better in this new A8. Rev matching works great in Sport and Track mode, both up and down.

thanks bobszo6 for the report on the a8, it sounds good so far, I am still torn but the a8 makes alot of sense, just personal preferences mostly, I dont plan on racing mine and i have some concerns about getting bored with the a8 but it sounds awesome !

Porsche has done a lot of work with their PDK, if the Z06 can hold up as well as this:
I'll be impressed.

Will the Z be a sub 3 sec car, maybe 2.8 to 60mph? What do y'all think? I'm still going with a 7sp. The auto I have in my c7 is just too boring and heat issues @ track stink. I'm sure the 8 sd will fix this, but I don't want to risk it. I can't keep buying cars every 2 yrs if I want to keep my wife.

Downshifts that crack off like a DCT? Well then. I'd still have a third pedal for my own personal fun factor, but this sounds excellent and I'd certainly love to try it out.

The ZR-1 was 3.4 sec 0-60. Subtract 0.2 for the new A8. The extra weight won't matter as much as it's already traction limited and has 6.5% more torque to offset the 3.5% weight increase.
3.2sec 0-60, that's it!
To get into the 2's you need AWD or some sort of transmission-destroying clutch dump gimmick ala Huracan. And 3.2's perfectly fine, that's Huracan & Ferrari 458 Italia territory.

Porsche has done a lot of work with their PDK, if the Z06 can hold up as well as this:

Either way kudos to Porsche for such great engineering. And will be interesting to see just how well the PDK stands up to that much power over that many years/miles of driving.

I see, so the one place where it really matters, it isn't as good….
But none the less:

a bit contradictive

They said that with the paddle shifters is slower but in full Auto is right there with the DCT.
