I am shopping for a 328 msport and the dealer i'm leaning towards swears that the '14 model is much beter to drive because that did some tuning and changed the exhaust. i can't find a damn thing online about that. is there any truth to this?

i'm ready todo something today, but finding a 13 I want is hard, and that estoril blue '14 is really looking good, but is it worth the price difference?

It's the same bro. The only major changes involved iDrive.

[mtbnole]

what changed with iDrive if you don't mind?

I just read another post about the 428 and it seems they may have used some trickery into making it sound better via the stereo.

No the engine has been modified. i just found this out today. Not just the Idrive.

Definitely go with a 2014!

This is bad, someone gets a piece of BAD info from a salesguy and then spreads to 3 posts in one day.

The N20 has been unchanged since it's inception. They did nothing to the engine for the 4 series. Your CA was wrong.

Thank you! Noobs I tell ya!

why a '13 if you have '14??? go with 335i if you still have room for your budget.

Leaving electronics aside, these are the parts recently changed on 328i N20 that can be attributed to MY2014 improvements:

- Engine block (8/13)
- Engine cover (8/13)
- Pistons (8/13)
- Engine mounts (starting 9/13)
- Automatic transmission (8/13)
- Driveshaft center mount (8/13)
- Front subframe (8/13)
- Front and rear wheel hubs (10/13)
- Brake lines (7/13)
- DSC control unit (7/13)
- Strut tower brace (7/13)

I'm not saying they are different in a significant way, they just have new part numbers.

updated PN does not automatically correlate to a change in the part itself.

That's right. I just didn't say it well enough.

Same part number = no change.
Different part number = many possible things, only one of which could be the actual change in the design and/or behavior of the part.

Thx!

I've had 2013 & 2014 328i M-Sports. I can clearly say the sound of the engine is completely different for 2014. I believe it's synthesized sound coming through the audio system - but there is no official information posted about this on line that I've been able to find anywhere. The base Comfort/Normal settings are fairly aggressive - and the sound is even more amplified in Sport mode. Even the base setting is a little over boosted for me, but at least it masks most of the N20's L4 trashiness.

Hmm, check out the fuse box key in the manual, there might be something there about noise enhancement.

Put a hand over one of the speakers and see if it sounds different

Just curious, why would they change the PN if the part its self were not changed?

I think subtle refinements were made with the engine internals, tuning or exhaust that really aren't something that the company shares with people.

I would like to refer to them as refinements. Different metals, manufacturing refinements, etc. Subtle refinements may or may not improve performance or efficiency so they are probably never really mentioned. I spoke with someone who attends all of the training, etc. so take it for what its worth. There probably were subtle refinements in regards to the N20 engine for 2014 as well as many other vehicles that the average layperson is not aware of.

In my experience with the 428i, there was no diesel-like clanking or clicking with the engine outside or inside. It sounded very smooth like my N55.

INside, it sounded even better, which makes me think that there is some sound modification, but the guy I spoke with says it is natural.

[mysticwizard]

is there already a M performance exhaust available for the 428i? Is it the same as for the F30 328i?

Semi annually the whole system is went through and updated, literally a variety of reasons for updated part numbers. Sometimes, same part, but a change of distributors/manufacturers.

To further rain on this parade, a new part number can be issued for an INFERIOR change, not an improvement. My Viggen had factory slotted rotors, heavy, $$$, made in Germany. After a couple of years they got a new PN, were lighter, made in China, but cost about the same.

Again, as to this silly assertion of some secret new and improved N20, I hope you understand how cars are assembled.

They are made at another factory and shipped for final assembly of the car at another, thousands of them in a row.

They have cars running down the assembly line, engines, front suspensions raised up and installed, the process called "marriage".

In the row of thousands of engines, whether LATE '13 or early '14 builds, they don't go to pluck an engine, and go wait...we need a secret special N20 for this next car because it's a '14, let me use my Spidey Sense, to look internally and make sure it's special.

I dont undertand but i agree

[jzcrna]

I know you are referring to me and I never stated that there was some new top secret N20, only that there were some refinements. So you can keep going and trying to create some kind of ego competition with yourself.

It's the same.

Sigh.

You posted on and on like you had some word from god on a improved n20 because you heard it from some CA.

And then boom people start buying into it.

All I have done is make logical counters.

Its not personal, yet you have made quite a few comments to me trying to make it personal.
