We're still hovering around the 0.3 mark, with the better vehicles around 0.25 - and have been for many years, the A2 is old.
To make a real difference, we need to get to 0.20 - and below.

What do you think about those designs taken from your link (especially Mercedes "boxfish")? I see them as a much more practical designs than a long boat tail. I don't think that a jump from 0,25 to 0,20 as a revolution. It's just one big evolutionary step which can be compared to weight and rolling resistance reduction.
A2 was ahead of it's time in many ways. For me A2 was a pure eco design, whereas new Mercedes A-klasse is just a normal compact car with atractive and sporty design. IMO that shows some clear improvement. It's interesting to see what the next A2 will bring.
