there will be new 4 series designations for the US starting with model year 2016 when the engines are reconfigured

428i (N20) -> 430i (B48), 435i (N55) -> 440i (B58).

4-cyl B48 engine will have 330i/430i designation instead of 328i/428i
6-cyl B58 engine will have 340i/440i designation instead of 335i/435i.
PHEV F30 will come as 330e, not 328e.
