my best guess is that it will happen for model year 2011 which will start being produced around June 2010 which means for orders in europe coming in a couple of months before that.

the reason I believe this is that is is scheduled that the S5 changes its engine in that timefrmae and I guess they will do relifting and that engine change at same timing. in addition it would be totally crazy to relaese the RS5 and have the relifting afterwards. and we all know that RS5 is goign to be presented in march 2010 in Geneva.

This past Saturday, when I asked my dealer this question, he said that the makeover would likely be on the 2012 model at the earliest. He felt that 'really' the 2009 was the A5's first year and did say that there are no set periods for the new makeover. He mentioned two or three Audi models that have been other/sooner than 4 - 5 years.

That can be right for USA/Canada as ther is delay of up to a year fo a change to take effect. here I am talking about Europe.

A5 was released in early 2007 here.

There may be a delay in bringing a model to North America, since they simply have to direct all early production to Europe, but there won't be a similar delay after a refresh. Audi isn't going to produce two different versions for different destination markets.
