Some of the price difference that you see between the A3 and A4 comes down to the fact that quattro AWD is standard on the A4, but not the A3. Adding quattro to the A3 closes the gap a little but the larger A4 is always going to be a bit more than a similarly equipped A3. Size is really the big distinguishing factor when it comes to these two cars. But your passengers are unlikely to notice a real difference in size as you can see from the nearly identical legroom. The size difference comes down to a slightly tighter turning circle for the A3 and a bit more trunk space for the A4.
