BMW models...what's the difference?

Question

I want to buy a used bmw and put money into it to make it a high performance car. i currently own an 89 240sx with an sr20det motor. i wanna get a bmw to try something new but i dont know which one to get. for example i was looking at the 323i's but i dont know the difference between the 323i's ci's and what other letters it comes with and what other series it has like a 3 series..lol. im planning on getting a 323 or 325 but i dont know which one is best for performance..so can anyone tell me from experience what the letters mean and the model #'s like 323 / 325 mean and what the series mean? and also which would you suggest to buy to build into a high performance car and also the prices of each model if they were used..thanks.

Answer 1

BMW vehicles follow a certain nomenclature; usually a 3 digit number is followed by 1 or 2 letters. The first number represents the series number. Generally, the higher the series number, the larger the car, and the more standard features and available options. The next two numbers traditionally represent the engine displacement in cubic centimeters divided by 100. A similar nomenclature is used by BMW Motorrad for their motorcycles.



The system of letters can be used in combination, and is as follows:



A = automatic transmission

C = coupe

c = cabriolet

d = diesel†

e = eta (efficient economy, from the Greek letter 'η')

g = compressed natural gas/CNG

h = hydrogen

i = fuel-injected

L = long wheelbase

s = sport††

sDrive = rear wheel drive

T = touring (wagon/estate)

t = hatchback

x / xDrive = BMW xDrive all wheel drive

† historic nomenclature indicating "td" refers to "Turbo Diesel", not a diesel hatchback or touring model (524td, 525td)



†† typically includes sport seats, spoiler, aerodynamic body kit, upgraded wheels, etc.



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



However, there are exceptions. The 2007 BMW 328i is a 3 Series that has a 3.0 liter engine. The E36 and E46 323i and E39 523i had 2.5 liter engines. The E36 318i made after 1996 has a 1.9L engine (M44) as opposed to the 1.8L (M42) used in the 92-95 models. The 2007 BMW 335i also has a 3.0 liter engine; however it is twin-turbocharged, which is not identified by the nomenclature.



The 'M' - for Motorsport - identifies the vehicle as a high-performance model 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.



When 'L' supersedes the series number (e.g. L6, L7, etc) it identifies the vehicle as a special luxury variant, featuring extended leather and special interior appointments. The L7 is based on the E23 and E38, and the L6 is based on the E24.



When 'X' is capitalized and supersedes the series number (e.g. X3, X5, etc.) it identifies the vehicle as one of BMW's Sports Activity Vehicles (SAV), featuring BMW's xDrive.



The 'Z' identifies the vehicle as a two seat roadster (e.g. Z1, Z3, Z4, etc). 'M' variants of 'Z' models have the 'M' as a suffix or prefix, depending on country of sale (e.g. 'Z4 M' is 'M Roadster' in Canada).



Previous X & Z vehicles had 'i' or 'si' following the engine displacement number (denoted in liters). BMW is now globally standardizing this nomenclature on X & Z vehicles by using 'sDrive' or 'xDrive' (simply meaning rear or all wheel drive, respectively) followed by two numbers which vaguely represent the vehicle's engine (e.g. Z4 sDrive35i is a rear wheel drive Z4 roadster with a 3.0L twin-turbo fuel-injected engine).





My suggestion: a 95-99 (E36) M3. Then put some money into a turbo or supercharger. The 94 was a 3.0 liter compared to the later 3.2 liters.

Answer 2

There was the 325i, the 328i, and the fabulous M-3. The M-3 was and still is the most powerful and most expensive 3 Series, but it did not become available until about the end of 1994 with a 3 litre in-line six cylinder engine and 5 speed manual transmission. There were two door coupes, 2 door and 4 door sedans, and a few cabriolets with all kinds of optional extra equipment.

Answer 3

the 3 litre m3 is a lot stronger and a better engine than the 3.2 evo if your putting a charger on it.

a 99 320 is a 2.2litre

323 is a 2.3 or a 2.5litre

325 is a 2.5 or a 2.3litre

this is bmw cheating with the emission laws.

Answer 4

I am looking for SX240 parts where are you located?

BMW's are very expensive fro parts if you are not working on your car your self don't' buy a BMW.
