I can't understand how someone could go that slowly in an A6, I mean you don't have to shift or anything. I only ran twice, my other run was also a 12.834 at 112.34. It's pretty hard to drive an auto slowly.

Inexperienced drivers are more than capable of allowing this to happen. Depending on mods, traction control can be of little to no assistance.

The only inexperience is someone who hasn't read the manual to understand what AH does and how to engage it with traction control off. No dragracing should be done without it.

I noticed a couple of things about that one because I have it too.
Actually updated data "closes the gap" in a few "questionable" categories.
I notice that it lists 60-0 braking as 113ft for all models. This would include the Z06. The have the specs listed for the Z06 in all the preceding categories. Come to this one and it brakes just the same as all the rest? I don't think so.
I am wondering how the 0-60 braking dropped all the way from 125 feet in '05 down, to 113 ft in the base cars, and from 116 ft down to 113 ft in the Z51. Again, I don't think so.
The 0-60mph base manual went from 4.3 seconds in '05 down to 4.2 seconds in '06. I am also wondering what they did to the '06 manualss that allowed them to pick up a tenth in the 0-60 mph time.
The automatics picked up a tenth from '05 to '06, but of course, they did have a transmission and gearing change over that time.
I also notice that they have all coupes listed at 186mph for top speed.
But in http://www.corvettemuseum.com/specs/...wertrain.shtml
..."Also, a lower fifth gear gives the Z51 better fuel efficiency and a higher top speed than base models. To increase durability in sustained high-speed situations, the Z51 and the base European manual-transmission models have a transmission cooler."
So there are a few inconsistencies with that page 28 of Corvette Quarterly.

I turn it off for that reason but if it really isn't intrusive at all I won't.

I guess you will have to ask GM to answer some of your questions!
However, my guess on the updated 186 mph top speed is that in 2005 they had not tested base cars yet (listed as TBD). By the time 2006 models came out, they had tested base cars for top speed, and updated the publication. The Corvette Museum link you report is for 2005 models. There is a Corvette Museum link for 2006 where they report 186 mph for all coupes. See the paragraph under Aerodynamics. "The C6 stands out as the fastest Corvette ever produced. The Corvette coupe can achieve 300 kph (186 mph) - a threshold that distinguishes supercars from the rest of the pack. The Z06 has even higher potential."http://www.corvettemuseum.com/specs/...chnology.shtml
Also Chevrolet.com states all coupes can reach 186 mph. Click this link and there should be an Atomic Orange coupe on the page. On the lower right of the picture click "about this photo". http://www.chevrolet.com/corvette/photogallery/

So they're calling the C6 a "supercar" now?

Ah I see that you have not been to a drag strip lately. I usually go on the test & tune night. With all the front wheel drive cars around, it is very hard to race on a night where no one breaks and puts oil all over the track. Cars are constantly breaking drive line parts.
In addition, the track prep at Englishtown leaves something to be desired and if you put oil on it when its cold..... competive driving mode, experience and etc does not help. I was lucky the guy broke at the line. If he had broken at the top end I could have ended up like one of the Mustangs that bounced along the wall on the top end last season.
Next time out I intend to try running with active handling on. I think that active handling & traction control are great but they have their limits.... they do not negate the laws of physics particularly when you have fluids on the track and your tires.

Last weekend at E-town a motorcycle dumped oil and tranny fluid all over the left lane right before my run.
After an hour of cleaning the track they gave us the OK to run.
I was in the right lane which they did not even clean up, they said it looked fine.
You bet I was glad to have AH on just in case they were wrong.
The video of that run is up in this Forum now.

I've never been misfortunate enough to do a launch on an oily track or blow up a rearend, but if I ever do, I'll be sure to have the help of AH on my side.

There are some hard core track folks on this forum and all of the post I have read from them in regards to tracking the car say the same thing. Leave the AH on. It is in your best interest to pay close attention to real world experience.
