This is a car we are not getting.
Pictured here is the 3 door model. As you can see, most of the changes are the usual BMW's "new bumpers and lights and don't even ask for more since this isn't all new".
(Although the rear lights are really different this time.)
Inside the biggest change seems to be a larger screen.
These are now available with the 3 cylinder engine from the new Mini Cooper in the base models.
