320i/325i/330i convertible (e93) engine code?

[BMWHeaven]

Hi all,
I was wondering what the engine code is for the new 320i, 325i and 330i e93 (3 series convertible).
I know that the engine differs from the sedan, touring and coupe versions.
The new engine has High Precision Injection, but no valvetronic anymore (no space for that in the cylinderhead).

Any ideas on the new engine codes? Maybe N53 or something?
Thanks!

The description of the 328 engine in the US E93 Press release is identical to the other E9X 328's - Valvetronic and no mention of Direct Injection. Maybe European versions will be different but I doubt it.

The 3 character designations are pretty generic. N53 would be Gasoline Direct Injection so that would probably apply to the engine you describe unless you're thinking of Diesel which would be N57. (Substitute a 4 for the 5 for 4 cylinder.)

N52 is the regular 6 cyl
N54 is the twin turbo engine
N62 is the v8 in the 545, 645, 745
N62TU is the updated motor in 550, 650, 750
N73 is V12 in 760

@jmonier:

In Europe we do have different engines in the e93, as you can see it this text, copied out of the press-release:

So it must be the N53 for the 325 and 330 then, the N54 for the 335 and an N4x for the 320?

Thanks for the link btw!
