And did you notice that's an auto in auto mode?

Okay, I definitely gotta watch the video now.

HAL is your friend if you program him right.

GM is on a roll these days. The lap times that the latest crop of Corvette, Camaro, and Cadillac V-Series cars can turn out punch way above their class.

The article I read in Autoweek said it was a paddle shifted automatic, and that you can see him operating the paddles in the video. I couldn't see it, but he was downshifting somehow, so I tend to believe them. Why would he do it in automatic mode?

Yes, but those cars fall much short in other areas. These are just numbers to brag about. Plus, I couldn't find for this video whether or not the car was in production trim.

The car being downshifted does not necessarily mean that the driver was initiating it...A well programmed track mode, or whatever they want to call it, can do a surprisingly good job at this as well.

Watch his hands. I saw two or three motions that might have been downshifts, but that still leaves 98% of all of the shifting done by the comouter. I don't think it lets revs fall below something like 4k rpm. Once you get wrapped up in the car shifting itself it gets hard to watch the actual lap. I did notice banging curbs at 130mph which was a little pucker inducing.

It's amazing how hard the car is still pulling north of 125mph.

Seriously impressive.

To prove how well they have setup the transmission logic/programming?

Or, heaven forbid, it might be faster.

That was fun to watch.

I'm OK with that. I'm not one of the ones that constantly poo-poos stuff like this. Fast auto, DCT, I'm all for it if it makes the car faster.

It had a roll hoop, and a six-point harness. Other than that, stock.

Now that I have seen the video.
Okay, WHAT transmission is in this thing?? It appears to have closer ratios than most manuals. Through the first half of the course it never dropped below 5400rpm after an upshift and this was shifting at about 6400 or so. DANG.

171-odd MPH and then the trans finds another gear!

Driver keeps on it at 181mph over a crest with a curve looming and THEN starts decelerating!

Driver also took some very good lines through some sections that I have never seen other drivers take before.

Also, it is a shame this is the ZL1. The ZL-1 was a drag racing partsbin special. The Z/28 was the weapon designed explicitly for road racing.

Maybe it has the 8 speed auto? I have a new camaro SS as a rental this week with the 8 speed. It's a blast in track mode.

That's what I was thinking as well. It did seem to do a very good job of keeping the rev's in the sweet spot.

Please elaborate on falling short in other areas...and numbers for bragging about...what then is your criteria for success?

Production trim minus roll hoop, race seats and harnesses...

Hmm, if thats the "drag racer" with an auto, imagine what the 'road Race Z28" with a manual will be like?

The new ZL-1 is not for drag racing.

It's basically a supercharged Corvette with a back seat.

Z28 is on its way allegedly. The fact that a ZL1 is that fast in a straight line and can turn and brake that well is amazing to me. Even the 1LE V8/V6 is supposedly amazing. Your never going to see me buy a Modern Chevy though as past mistakes still haunt me.

Some interesting electronic trickery going on, I'm guessing. He seems to often slam the throttle open on corner exit, yet there is no oversteer. There does seem to be mild to moderate understeer. And I think he's fully utilizing ABS. So I'm guessing he's got a track mode engaged on the stability/traction system. Which means it's a pretty good system. And GM has had a good such system on the Corvette for some time.
