DSG over Quattro for me. I can't see them offering both DSG and Quattro on the smaller engines for quite some time. Look at the A3 ... DSG and Quattro are available individually (for the first couple of years only on anything over 2.0) but together they are still only available only the 3.2 beastie.
Audi needs to get that 2.0 TFSI to the US market. With the price of the gas now days, that will sell so good. I so want one. Bugging my dealer for months to get it......ordering it as soon as it gets here....if it gets here
The German site has now announced the 2.0TFSI for the A4 but not for the A5.
The Audi UK site doesn't yet mention the 2.0TFSI for the A4 never mind the A5.
No sign of DSG aka S-tronic yet on any A4 or A5 model on any site I've looked at (other than the general press releases of 7 speed S-tronic some time after the Q5 launch ... blah, blah, blah)
To be honest, I can't see why Audi would bother with new engines for the A5 at the lower end of the scale at this point given that they already can't meet the demand for cars with the existing engines.
