A6 quicker 0-60 times? Does it not have an extra shift that the A4 does not? Hair spilting for a door length, time will tell. I do know the ZO6 is for sure quicker!

Mine is A4, and 3.15's and my car shifts into 3rd at 85mph, his shifts into 4th at 95mph.

Now from a roll, or around town driving, it is easier for him to keep the rpms up than me, making his a little more fun to play with, but then when I manually shift my car, I hardly ever have to take it out of 2nd gear since it will do 85mph in that gear, and that is faster then most any corner I am going to take.

I was first upset when I heard a 6 speed was out with paddle shifters, but after driving our two cars, I couldn't find any reason why I would want to switch out my car. The biggest difference like I said was the paddle shifters were just much easier to use than my console shifter.

I would have rather had a 6 speed, but daily traffic jams suck!
Both are great but no gain in speed or 0-60 means no trade out of my A4 3:15!!!

Well, the A6 is at least as fast as the A4 with 3:15 and most likely slightly faster espcially off the line. And due to its taller 6th gear, it does get better gas mileage as well. The A6 is a win win situation.

Not according to TEAM CORVETTE and CORVETTE MAGAZINE posts. Times are identical. A6 and A4 3:i5 and I would hope they would no more then all of us! Maybe slightly faster than A4 2:73

Yeah, but the A6 still gets better gas mileage and shifts smoother. Can't beat that.

I think you guys are missing the real opportunity here. If you change the rear end gearing to a set of 3.42's that A6 is going to cross the finish line in 4th. However the real advantage is going to be leaving the starting line because the overall gear ratio with that whopping low 4.02 first gear is going to be 13.75

The problem will be keeping it glued to the track.

Yet on the freeway at 80 MPH in 6th the engine will only be turning around 2300 or so RPM. Still a very tame number for a street car.

I wonder if I can shoe horn one of those into a C5?

Hey Chevy, How about giving us back the 3.15's from the factory with the A6 and Z51.

Ok, me and dave have been playing a little more. His car runs at 2100rpms at 80mph on the freeway when the auto is in 6th, mine runs at 2400rpms at the same 80mp. At medium speeds if we both lay into it, lets say at about 50 to 60 mph, his car gets a better jump out then mine, but then we sit in the same position with no pull on eachother. My average gas mileage has been 18.5mpg for mixed driving, and I am on it all the time. He drives even more aggressive than I do and his mileage has averaged out to 19.5mpg mixed driving. So definatly has some advantages. Also when getting on it with about 50% throttle, my car downshifts violently and wants to rip off, his seems more tame than mine at mid throttle applications and easier to control with the throttle. The local tuner here told me that with a tune that mine would be much better a driver than the setup now.

Do you both run with TC/AH completely off?

50/60 is giving him a big advantage because of rpm's---you should try 70 and I would bet you would see a different outcome.

Smoother shifts yes ,better gas milage yes, BUT MOST IMPORTANTLY FASTER NO!!! I was thinking of trading out of my A4 3:15 to the A6 but since the performance is the same Im glad that I dont have to loose all my money to trade up. Ill wait for GM to increase the horsepower then I will have too trade up because MORE HORSEPOWER IN THE ENGINE MEANS FASTER CORVETTE NO QUESTIONS ASKED!

A6 gear ratios the same with Z51 or without WHY? Is there a price decrease for the Z51 option or is it still $1695?

Same price, I just dont understand what GM was thinking, and they make you pay $1250 for the auto! Its a like a double slap in the face!

Trade in the A-4 C-6 when they come out with the Z-06 with an A-6 automatic.

Default Then again which transmission will be more reliable as it ages?

The A-6 is new so there is no track record yet

Here's where you should notice a difference between the two cars.

I had a 3.15 01' vette, and this is where I couldn't stand the A4; when I was doing 37 to 40 mph and punched it. Guess what, 1st gear was too low, so it would gear down to second. Well, second gear is going all the way to 85-90 mph. That killed me in more than one race. So unless I slowed down to 30 so that it would gear down, or if I had to pass someone(which seemingly I was always doing 40 at the time) that's a long stretch to be in second gear and it was always sluggish till about 65. With the A6, that should no longer be an issue because it's 2nd gear is much more useable, and if you swapped rears to a 2.73 or 3.15, then it would make an even bigger difference.

You nailed the a4's weakness---37 to 40---deader then dead---my Sienna mini van would beat my c6 from 40 to 50---sad to say but I'm serious.All of us saddled with the A4 will be backing down to 35 before we ''PLAY''.

Yes, that is the week point, but with tunning you can get that changed, just like my last vette was bad at that speed too, and would not down shift, until tuned to do so. Someone asked and yes, both traction and active handling were dissabled. I must admit thought, that after driving the A6 car a couple of times, for sporting driving, it is a lot more usable and fun. But from a speed standpoint, I can't see any difference between the two cars!
