Whats the "E" for??
 

what does the E in E46 stand for the model type what?

E stands for Entwicklung (German word for development)

And this is where you can find almost all the E numbers with the cars they represent: http://www.bmwworld.com/repairs/codes/vehicles.htm

wow... there's finally a site stating what divisions each bimmer is in the e and a number... been wondering that for awhile...

*uzi*

That's weird, on that site it says the Z1 falls under E30.

Maybe because of the m20.... But then there are other series models that share the same engine..... hmmm
