 Have an A4, love it, decided to get an A3.  Worse mileage than our truck, turns 3000 RPMs at highway speed, can't even make 10MPH in 1st gear.  TERRIBLE design point. We've contacted Audi, they blame everyone else (dealer, etc) -  but it is the worst design I have seen in 30 years of buying cars.  Lighter than the A4, same power (V6), smaller, and about 10MPG worse than the A4 - blows my mind.  We won't touch Audi again - due to Audi USA refusing to discuss, acknowledge, suggest fixes (ie, different gear ratio in the differentials).  By the way, I'm an engineer, have extensive auto experience...
