Default BMW News (All news and spy shots here please)

ok, with all the talk about the upcoming BMW cars with reference to their designations, i realize it can get confusing to some people, so i thought i would put together the Designation and Engine code table. These are for US vehicles. Obviously Europe has alot more diesel powered vehicles and alot of other varieties. Plus, Europe has the E87 1 series, the US doesn't

a few quick clear ups before going on:

Model indicators:
i = fuel injected
A = Automatic
C = Coupe
c = convertible
s = sport package
M = Motorsport
P = Protection
t = touring
e = economy
d = diesel
x = All wheel drive
Engine Code break down:

M = standard production engines
S = Motorsport engines
N = New Generation engines

\/------------ Engine code
M54 B 30<--- Displacement in Liters
/\ -------- Fuel type B= Benzine (German for gasoline)
.................................. d = Diesel

TU = Technical Update

That said, let's continue

more explanations:
E36/5 = 3 door touring E46/16 = All Wheel Drive E46/3 (E39/3) = sport wagon E46/2 = coupe

That's the US list for now. I may adjust this to clear it up a bit more if anyone is confused by anything.

UPDATE (12-07-06)
With the 2007 MY, there has been a change in the engine designation. It finally makes sense!!

Keeping with the same format as before (N52B30) there has been some clarification and revision for what comes next. The TU designations have been dropped, and you may notice that the new suffix o1 or u1..pay attention now as it will all be explained

the first change comes in the numbered designation. The first number is the Engine Type. 4= 4cyl, 5= 6cyl, 6= 8 cyl, 7= 12cyl and 8= 10 cyl.
the second number is the engine system: 0= baisic engine; 1= SULEV/PZEV; 2= Valvetronic; 3= Gas w/ Direct Injection; 4=Gas w/DI + Turbo; 5= Dual Vanos + Valvetronic; 7= Diesel injection + Turbo

the Letter in the middle is still fuel type but there are some new additions to the possibilites here. Along with B and D, we now have E= Electric, G= Natural Gas and H= Hydrogen

next numbers are engine displacement in tenths of a liter (no change here)

and next is the engine's output rating: T= Top rating, O= High Output, M= Medium Output, U= Low output, K=Lowest output and 0= New Development

the final number is the version of the engine, numbered 1-9.
