When I grew up, we thought we were really cool when we’d identify BMW models by their “E” numbers. There was the E36, which was the 3 Series that was sold from 1992 to 1999. There was the E34, which was the 5 Series sold from 1989 to 1995. There was also the E39, and the E24, and the E21, and blah blah blah. I thought I was especially cool because I knew the X5 was called the “E53.” I stumped people with that one for years.
These names were useful because BMW doesn’t really change their model names. The BMW 3 Series, for instance, came out in 1975, and it’s currently in its sixth generation. It’s a lot easier to say “E36” than “the one with those cool square headlights and that giant air vent in the center stack.” Same with all the other BMW models.
Now, when I was growing up, I heard that BMW used “E” in front of these numbers because “E” stood for “Entwicklung,” which was the German word for “Development.” So the E24 was the 24th BMW development, and the next model they released was the E28, which implied there were some “Developments” in there that didn’t see production (plus the M1, technically the E26, which did). This is why the numbers were a bit haphazard: There was no E35, for instance, or E40.
Then marketing got a hold of the whole thing.
It seems that at some point in the late 2000s, BMW’s marketing department started to realize that the “E” numbers were a really popular way to identify their cars, and they decided they were tired of the weird names — “E forty-six” didn’t really roll off your tongue, BMW apparently figured, and if the cars were going to be known by these numbers, they wanted the numbers to be easier to identify, easier to remember and easy to say. This began the tradition of only using numbers ending in zero. After the E65 7 Series in 2001, it’s been mostly just numbers divisible by ten: the E70 X5 and the E90 3 Series, for instance. (Oddly, the 1 Series was the E81, but not many cars have deviated from this pattern since.)
But I could live with the numbers ending in ten. Where marketing really screwed things up was when they abandoned “E” and went to “F.”
Like many people, I figured that after the E90 came out, the next car would be the E100. That would make logical sense. But these cars were no longer being named by the engineers, but rather by the marketers, and they decided 2-digit numbers made more sense. E was out, and the next car was the “F01,” which refers to the recently replaced 7 Series.
Now this is where I have a bit of a problem with the whole thing, because the entire point of the “E” numbers in the first place is that the E stood for “Entwicklung,” which was the German word for “Development”!!! Now the “E” is gone, and the cars are all called “F” something, which doesn’t even make sense. There’s the F10 5 Series, the F20 1 Series, the F30 3 and 4 Series, blah blah blah. This cool thing that used to be known only to car enthusiasts has now been turned into a marketing ploy, and it no longer even really means anything. Maybe even less logically, BMW has recently released the “G30” 5 Series, even though they only got about halfway through the Fs.
Me, I think I’m going to go back to describing them in the “old” way. “That 5 Series?” I’ll say. “You know the one? The one that’s a little too big, with all the electronic stuff.” Find a BMW for sale
