E38, E46, E39, etc. What's it mean? I don't see a pattern among them. How does BMW decide to number it's E- and F-Series cars?

Anyone have an idea?

This question has been asked and answered many times. Try searching.

They count up from e1. Around e99 the design numbers rolled over to f01.

I searched "chassis code" among others and mostly got back "I have chassis code E36..." or VIN decoding posts. I thought maybe someone knew off the top of their head.

Believe it originally began as design or concept numbers. For example, an E46 is design number 46. The E stood for the German word for design/concept, but which exactly it was escapes me. Now that things have rolled over to the F series of chassis codes, it's changed a little. As far as I know, the F doesn't stand for anything, and was just used because it comes after E.

Yep.. They just go in order. When they got to 99 thry went using f instead. The numbers that never made it to production (like e37-e45) were concepts or internal projects. Kind of scary that they couldn't go to a 3 digit code likely due to some software limitation. E stood for eintwiklung which is german for development.

ahh. Try searching on BMW e numbers.


MINIs all start with R. The R probably stands for Rover.

Dunno if Rolls have codes or not. They don't on realoem.
