The first "super hero's" crest was designed in a shield shape to display protection and used primary colours due to the limited allowed pallet for comic book printing.  As time went on, the shield became more abstracted with a focus on the famous "S" in the center.  This increased recognizability of the logo while still keeping with the traditional style.  In 1948 the logo first began to exhibit the modern shape and design and the colour choices were officially errated to tie into Superman's back story as the "Last son of Krypton."  The yellow and red was said to be for the sun god of Krypton. In June 1940 the superman logo became the five sided pentagon because it was easier to draw and read.

The BMW logo has been very constant and consistent over the years.  The largest change was the font from serif to sans-serif in the 50's.  The BMW checkered pattern is thought to be representational of spinning propeller blades from when they built those. the blue and white is also symbolic of the Bavarian flag, the origin of the company.  In the 70's and 80's the motor sport logo had a lot more blue to represent water with the red ring that appears to be a boat bottom. In 2000 BMW logo changed from the 1954 flat logo to a more beveled 3 dimensional logo to make it look more dynamic. http://www.logoblog.org/bmw_logo.php
