i know the "E" in the current BMW models stands for Entwicklung, which means evolution or development in German. what i don't know is what the F-Code stands for that the new chassis models coming in the near future. Also why did the numbers jump so high in E-Code?
for example 3 series went from E21-E30-E36-E46 and now E90 what happened to E56-E66-E76-E86-E96 or any numbers between that could represent the 3 series.
Also, does any one know what the logic was for assigning e46 to the 3 series and e39 to the 5 series etc... do the numbers represent a significant to the chassis models??
