2006 automatic/ performance axle
It appears from the price guide that you must pay $1250 for an automatic. as opposed to the no cost choice on the 2005 model. Yes , I know you get the paddle shift, but if I wanted to shift this car, I would buy the 6 speed. I also observe that G90 performance axle ratio is not listed as an independent option. Probably still available inside the Z51 package, but not stand alone.

To each his own. G90 is not needed with that 33% lower first gear in the A6 versus the A4.

Is there a chance that HUD is standard with the new A6 (so that one can see what gear they're in more easily) and that's part of the reason why it's a bit more costly maybe?

Consequently, some drivers will have to somehow find a way to live without the HUD, utilizing their tach and ears.

The A6 4th gear is no where near the same as the A4 top gear.
4L65E (A4)= [3.06,1.63,1.00,0.70] (4 speed auto)
6L80E (A6)= [4.03,2.36,1.53,1.15,0.852,0.667](6 speed auto)
4th in the A4 is about the same as 6th in the A6.

Well I am not sure about mileage.... Lugged engines don't always get better mileage just because they are running slower. At 40mph my car gets better mileage in 3rd gear. Even at higher (70-75) speeds the gain in mileage (3rd vs 4th) is in tenths.

2.56*x6L80E = [10.31, 6.05, 3.92, 2.95, 2.18, 1.71] (*expected axle with A6)
2.73*x4L65E = [ 8.35, 4.45, 2.73, 1.91] (*current std A4 axle)
3.15*x4L65E = [ 9.64, 5.13, 3.15, 2.21] (*current hi perf A4 axle)
With the above numbers I would restate your comment to say that the A4 in 4th gear with the 3.15 differential is most like the A6 in 5th gear (not 6th). The numbers are 2.21 for the hi-per A4 and 2.18 for the expected A6. Okay?

So what is the verdict? Is the 4 spd. auto better than the A-6 which has no 3.15's?

I think the new tranny is ABSOLUTELY EXCELLENT!!
I like the new low - and high - ratios and think the paddle shift is just right! Having driven MANY stick shifts in the past, I'll bet that, with the operation of this new tranny, stick shift buyers in the future will dwindle fast.
And, that there will be a lot of 05 stick AND auto trade-ins to get the new A6.
Also - 1250 is a VERY fair price! (Unlike the chrome wheels @1995.)
