The new design looks like the current one except everything is just a lot "busier", which I don't like. Too many lines and angle changes for me. The thing I LOVE about my 2014 is the lines are all smooth and simple, it looks aggressive because it doesn't look too complicated of busy. It's like what they did to the new BMW 4 series. My 2010 looked amazing, just smooth lines and sleek looking, then they just did to much with the new one and now it doesn't look as proportional and smooth as the previous generations. This happens when they try to make something already awesome, better.
As far as the interior, well I like that a lot. Definitely a big improvement.
