What makes the a6 faster?

Yeah, what he said

Manuals are a hoot but thie auto is precision! Why do ya think Ferrari and Lamborghini don't offer manuals anymore. F1 and Indy cars the same! I see a trend here! It suck to admit but we humans will never match the shift times and precision the auto has in this car! The stick gives the fun factor absolutely but the auto will give you the same result once you learn how to drive it! ( ya I said learn to drive an auto) People who have driving the auto aggressively know what I'm talking about! It takes more skill than one may think. With that said HANG IN THERE NASCAR with the 4spd forever!

hmmm I don't think you really understand what transimsions are in the cars you are talking about.

the are twin disc or single disc computer controlled manuals in ferrari's and lambo's. the 458 has a getrag box that is a seven speed manual.

the torque converter tap shift automatic in the ZL1 is about as different as it gets.

that being said the 6L90 E is light years ahead of a TH350 or TH400 but I still don't feel "completey in control" of the tranny when I drive one. I don't see $2600 more in the car basically.

I would bet that you if you tap shifted in you ZL1 you will be no faster than just letting the computer shift. hence why I don't like tapshift auto's as much. the car is still doing the driving. If I lived in a major city I might feel different though due to traffic ha ha.

for a Daily though SMG or DTC boxes can have issues chatter and such. the shift speed is insane though.

I wouldn't even think about it if we had one of those trannies in our ZL1s!!!

I never use paddle shifting with cars that offer it. even with the preloading, it won't shift any faster compared to the S mode.

the only thing I would say is that, it'll let you hold the gear so you can track it and have control of the gears and RPMs you'd like to stay at. that's it.


the dilemma i'm having is that I hate driving a daily driver in traffic with a manual. I tried teaching the wife how to drive the Z06, but she couldn't get it, because it's not a friendly clutch. i'm afraid she won't pick it up in this car either, and sometimes it's preferable I take her car for some occasions.

but I love the spirit of driving a manual and having that manual control.

if anyone has flown a fly by wire plane and a mechanical control plane(or even used a manual zooming camera lens compared to a by wife system) you'd know exactly what i'm talking about.

the 6L90E is not anymore advanced than a 4L60E we had in our 4th gens except the software updates and 2 extra gears. and 4L60E is nothing special. I had it in my Trans am.

I'd like to see the a6 on a track (road couse) and see how it compares to a m6 (i looked on YT for videos, but nothign like that... only for 1/4 tracks)

every time I have messed up a launch, I've had horrible times.

I thought however that the launch control minimizes this and controls the launch for you? with some sticky tires, 1.7-1.8 second launches are possible

I think manuals will always be better on road courses because in that situation shift time is such a small part of your overall track time that the difference between an auto shift time and a manual shift time doesn't affect your lap time. Plus on a road course then the true manual trans has less drivetrain loss so you can put more power down to the wheels coming out of corners.

On a drag strip then it's such a short period of time where .01 seconds and even .001 seconds matter so much that the auto will obviously have the advantage when it comes to shifting faster and without errors.

For me the manual trans is so much more fun to drive I couldn't imagine getting into my toy car and not being able to shift the gears manually.

I wonder if "S" mode also utilizes preloading - can't really think of a reason for it not to since by definition you're after something other than relaxed transmission behavior.

I know I've seen a video of an AT Camaro out on a road course, just don't know where it was linked from or whether it was a ZL1 or not.

Anyway, I'd seriously consider adding some supplemental transmission fluid cooling for anything beyond a moderate-paced introduction, for reasons involving coolant temperature and heat soak. Plan on the torque converter not being locked up much of the time and a lot of fluid heating happening as a result.

Beyond that, any gains in the popularity of ATs on the road course is going to be a little like "picking yourself up by the bootstraps". Pretty slow in the beginning.

Chief engineer ( Al was it?) Says the vehicle is warrantied for tech track use, so I assume it (a6) was stress tested at the track for 24 hours as well.

Its like the dey sump. If oil pressure was an issue, they would have put a dry sump. Apparently it wasn't an issue on the stress test that it wasn't put in, and its still warrantied if you KB the engine

Well I can run some people down from 3 or 4 car lengths back but I've got to have at least a 250 horsepower advantage. (sometimes I do). My very best 60 ft time to date on about 30 passes is 2.05. But I have never made a pass with any kind of drag tire on this car. I ordered the Weld wheels and for some reason it took over 6 weeks to mine the ore refine it and spin it into metal and ship it to me. While this was happening I blew my engine on a roadracing course so when I finially got the wheels I didn't have a motor. Got that all fixed for now but all my local venues are closed until spring.

The "launch control" is not a very fancy piece of electronics at all. What it does is, if you mash the gas with clutch in it holds the rpms somewhere around 4500 rpm until the clutch is released and then it raises the limiter back to the redline. 4500 may work fine for a bone stock engine on a set of drag radials but with over 700 whp on stock tires this just makes for spectacular smokey burnouts which are not conducive to good times. I really don't know the exact rpm because I gave up on that feature after about 2 smoke shows. I like the manual but at least on stock tires, it is hell trying to manage the wheelspin. I will probably try launch control again once I mount the drag radials but suspect the rpms will still be to high to get a good launch at my horsepower level. That feature was set-up for the stock car.

Warrantied and passing the stress test does not mean that the heat issue and the timing that gets pulled as a result isn't happening. If anything, I'd expect the timing to be fairly aggressively pulled as a function of temperature for this exact reason. That would be consistent with what the drag racers have found about running the car in warm/hot weather.

What good is having 580 HP at the beginning of a session when you're down to 500 or less 15 - 20 minutes later when your driving is more likely to result in better lap times?

[11B250]

Well I would say 24 hours slightly more than beginning of a session... Lol

two ZL1's, same mods, same day, same track, with equal drivers, one is a manual, and one is a auto, the auto will be faster, even though it makes a lower number at the rear wheels. FACT! lol

Such a true statement!!
