I don't know where you are getting this wrong info, but please stop.
With your thinking... this car:

.. share a platform.
Nope. Sorry, wrong answer.
Engineering teardown. They take the previous generation, fix/upgrade some components, re-style and it's a 'new' car. There have been several generations between the two you show. Believe me, it's fustrating to fix problems when components get re-designed every generation and new problems creep up, then go benchmark competitors that have been using the same (refined) components for generations.
IIRC, the 3-series never re-started with a blank slate. They choose to fix/refine what they don't like about the previous chassis and go from there. To be honest, that's why it has such great driving dynamics with a strut front suspension; they kept refining it generation over generation.
Maybe it's a matter of perspective.
