They don't sell the A1 in the US, and that version is actually the S1 and cost £27k for the base version when launched here in the UK. It's a bit of a one-off they sold hardly any of them.
Again, there are fast A3s but the vast majority sold aren't that quick.
Not too surprising. According to [1], the A3 and A4 mostly have 0-60 times worse than 6.5s. You've got to get up to the recent A6's to beat that.
