BMWs follow a certain nomenclature in the naming of many of their vehicles; a 3 digit number is followed by 1 or 2 letters. The first number is the series number. The next two numbers traditionally represent the engine displacement in cubic centimeters divided by 100.

The system of letters is as follows:

* d = diesel

* i = fuel-injected

* x = all wheel drive

* L = long wheel base

* C = coupe (no longer used)

* T = touring (wagon/estate)

* t = hatchback

* g = biogas

* s = sport package (Typically includes front sports seats, spoiler, aerodynamic body kit, upgraded rims, etc.)

* e = eta (essentially ''economy'' in English)

* es = eta sport

For example, a BMW 760Li is a fuel-injected 7 Series with a long wheel base and 6.0 litres of displacement.

However, there are exceptions. The 2007 BMW 328i is a 3 Series that has a 3.0 litre engine. The 2007 BMW 335i has that same 3.0 litre engine, however it is twin-turbocharged and not identified in the nomenclature.

The 'M' - for Motorsport - identifies the high-performance M vehicle of a particular series (e.g. M3, M5, M6, etc). For example, the M6 is the highest performing vehicle in the 6 Series lineup. Although 'M' cars should be separated into their respective series platforms, it is very common to see 'M' cars grouped together as its own series.
