**** Quite often, I get asked about BMW designations. What does this “ti” mean? What is the difference between the 525i and a 535i? E thirty what? So I decided to write a small article that would try to explain the differences between the designations and try to clear up some confusion on the subject. That said, here are some questions I have received.

What do they call my car an “E” something when it’s a 325i, 535i, etc..?

* When you hear you car being referred to as an E classification, what they are referring to is the body style of a particular car. For instance, BMW has produced a 3 Series model from 1976 to 2003. Naturally, the body style changes over time, so to avoid confusion; they refer to the 1976-83 3 Series as an E21, the 1984-91 cars as E30, 1992-99 cars as E36, and the present models as the E46. Keep in mind that certain early cars do not have an E number. Here’s a break down of the “E” numbers as well as the early designations

What do these letters on the back of my car mean?

* Traditionally BMW has used a series of letters to denote differences between models. For instance “is” would mean injected sports. Here’s a breakdown of the letters and what they mean. Keep in mind that various BMW’s used combinations of these letters. However, these letters are the most common.

i**** Fuel Injected
is*** Fuel Injected – Sports. Sports package, with better suspension, sway bars, etc..
ic*** Fuel Injected – Cabriolet, Convertible models
e*** ETA model. Built by BMW as efficiency-minded cars during the 1980’s
es** ETA – Sports, ETA model with sports package.
Ci** Fuel Injected – Coupe. This designation is used on most modern BMW’s
Csi* Fuel Injected – Sports Coupe.
iT*** Fuel Injected – Touring.* BMW’s station wagon.
iX** Fuel Injected – All Wheel Drive.
Ti*** Fuel Injected – Touring Compact. *
Tii** Fuel Injected – Touring International. Used only on early cars.***
M*** Motorsports.* M3, M5 for example, BMW’s hot rod.
L**** Luxury.* Basically a normal car fitted with full leather and all options, i.e. L6, L7
