A4. Nothing was said about the diesel though.

Audi AG and AoA will learn how to market cars here in America. When? Well, I've been waiting since 1984, and they haven't got it right yet!

the MB 2006 CDI diesel. But, my guess Audi will produce this diesel and we'll see it mid summer.
Just a guess. Hopefully, the wait is not too long once available.

personally I'm waiting for the avant. but undecided on whether I'd be willing to go with the 4 cylinder.

I would consider the 3.2 but knowing a big turbo setup would power me up to around 330-350 HP, (as they are completing 2.0 set up now).
I guess I would have to look at the cost difference and how the 3.2 runs. It's supposed to be a better motor but torque does not start pulling until 3k rpm. So it will not be the fastest off the line but should be an efficient smooth engine.

Even if I stuck to the ecu change, I'd be getting 241hp/292lb-ft off the $599 APR 2.0T stage I program. This is what keeps me wondering if the 2.0T should be the next engine.

Plus, it seems like there would be a weight savings of about 100lbs by sticking to the 2.0T.

However, last time around I found Audi's 6 cylinder to be much smoother than the 4 cylinder 1.8T. With the 1.8T I would constantly feel this buzzing vibration that was beyond my level of acceptability. But it is highly possible that with the 2.0T they have lowered the vibrations to a level I could live with.

What is it that keeps you from a 2.0T, and modding it to a stage II or III?
