BMW E numbers.

A couple of weeks ago there was a question about finding the E number for a car. Just out of curiosity, have the E numbers any real significance? They seem to be almost randomly allocated.

There is no particular significance to the numbering sequence. The numbers simply designate the various chassis designs. the 3 Series cars have been with us for a long while, and come on several different platforms, these platforms are defined by the E Nunmber. Obviously, the same holds true for the various iterations of the 5- and 7 Series cars as well.

The only real significance is that the bigger numbers are later designs.

While that seems to be true today, there are huge gaps in the numbering sequence, and a lower number could (in theory) be used at some point in the future. Another truism today is that the numbers are all E, and they are all 2-digit (plus the letter) numbers. They will run out of numerals if they continue on the current trend, this would mean they need a new letter, or expand to 3-digits.

But it indicates an F1 is the next 5 series car scheduled for 2008. That's pretty close timeframe. Maybe they know something here?

And I'm already planning on replacing my Z4 (E85) with a Z10 next year!! (Like Jeff said, "it's Wikipedia, so...")

I saw a list once that explained many of the "missing" numbers at the time. They were mostly cars that went through some part of development before they were canned.

    Given that the people assigning them are German engineers, I doubt they're random; it's just that from outside, we don't see what system they're using. The only real puzzle is the move from small jumps between models to where we are now: E30 - E36 - E46, E22 - E32-E38, E28-E34-E39, those are almost linear and all of a sudden we're in the 90s? Some internal change used up a lot of E numbers. I'm curious if what we're seeing now, with the 3-series having different numbers for each chassis, was always going on internally. Or maybe the E47 is a BMW Polo shirt in lime green.     Porsche did the same thing. The 911 went from 964 to 993, then slowed to 996 and 997? The Boxster came out *after* the 993, and it's the 986; could be right though, since I don't remember when the concept for the Boxster appeared. It might have been before the 993 was released.     epbrown -- "Everybody wants a normal life and a cool car; most people will settle for the car."

Regarding Porsche numbers, coincidence or not, here it goes:
- the 930 came after the 911, with a 3 liter engine; - the 964 was the fist 4wd Carrera 4 (besides 959 supercar that came before); - the 993 came out in 1992 but as 1993 model year; - the 986 Boxster came out in 1996; the same as the 996...
For the rest, I do not know...
