Hi everyone,
I'm currently in the market to purchase a new(to me) BMW 335/340.

I think the biggest difference between 2015 and 2016 is the engine.
If that is the case can someone tell me which one they would recommend.
And if it's not only the engine, what else are some of the biggest differences.

I apologize in advance if this is a topic that has been heavily discussed, If so, please share the link to it.

Thank you very much.

Biggest differences are 340 is closed deck robust engine similar to ///M while n55 is open deck..Intercooler is air-to-liquid as opposed to air-air which is better..bunch of tech upgrades..
I switched from '10 335i to S4 back to '16 340 w/mppsk.. I drive my buddy's f80 often and I can tell you performance wise it is almost on par with f80..Id recommend b58.. it may feel a bit heavier but it's a great engine and solid car

The 2014/15 is the best year to buy... highest ranking reliability those years... also it's a 100lbs+ less in the front end compared to the 340.... resulting in better handling.... I found this after driving both also... these are the reasons why I bought what I did...

I have had several N55 engines over the past year, and now two B58s.

I much prefer the B58.

Once they are both tuned it comes more down to handling and reliability...

340i Just for the Lci parts.

This is super anecdotal evidence, but if I were to do it again I'd go back and find a 2015 335i. The N55 motor in that car is bomb-proof and proven over many years in many vehicles. The B58 in my 340i developed a rod knock up at 16k miles and needs to be replaced, and the car doesn't feel any faster to me (although to be fair my 335i did have the MPPK and MPE)....

I have a 2014 335i Sport Auto (EWG - Electronic Waste Gate)with MPPK, MPE and Dinan Intake. I was pondering a 2018 ZHP manual (this has the MPPSK and LSD). If I was a guessing person, the 335i MPPK/MPE is 340HP vs 355HP for the 340i. My initial drive I noticed the power between the two was nearly identical, although, the 340i seemed more linear (less peaky) particularly in mid-range (however, the ZHP had less than 100 miles and my 335i really perked up after couple thousand miles). I noticed the updated 340i steering a little more responsive than my 2014 F30 (most likely due to the upgraded 5 bolt strut system and upgraded electronics for the steering), As for the manual trans, I really liked the up-shift rev match on the down shifting, it was very interesting.

This may a tough comparison as these are different engines, but the reality is the overall minor difference between the two for daily driving, therefore I would choose the 335i EWG and get a better price and the bulletproof N55. Either way would be a good decision though, good luck!

I had a 2015 335 with the power kit and MPE. I now have a 2018 340 with the MPSK. The 340 feels about 100hp faster.

If the only difference was the engine, I'd probably go for the 335i. The B58 seems like a solid motor, but it was pretty new in 2016 so might have some long term issues. If you plan on doing significant engine modifications, the B58 might be better though since it has a closed deck block and water to air intercooler.

However, there were a bunch of incremental improvements for 2016. Slightly improved suspension, newer iDrive version, upgraded tail lights, and if non-M Sport, revised bumpers. Otherwise, everything should pretty much be the same. As far as the upgrades go, they are fairly insignificant in my opinion because the suspension difference is pretty minor. IMO both cars need upgraded suspension if you're looking for a very well handling car. The upgraded iDrive looks nicer but doesn't add any significant features except for wireless CarPlay. Tail lights do look nice but can be upgraded if you really want them for about $500-$600.

So it really depends on how much you value those upgrades. The LCI upgrades for the F30 were relatively minor and on the street, LCI cars don't look much different from non-LCI cars.

340 for me

I'd wait a few years for the bugs to get worked out before picking up a 340i.

The only other time that I had a bad experience with one of my BMWs was a 2008 135i, which was an early N54. Apparently I'm not good at learning my lesson

Yeah, it's a tough one to make.. I had the 2008 335i, so I know what you mean.

I'm also considering modding it, so we will see.. I have so much to read. I've been away for a while and not keeping up with any of it.

Have you modified yours?

That's like asking if I breath air... lol....

Of course... I have everything (MHD/CP/FMIC) except the pipe on it right now and I'm happy... the pipe is going on as soon as my new pipe clamps come in the mail later this week... and changing out to new plugs... Love my car... I've owned it over a year now and still very very happy with my decision... Knowing what I know now I'd purchase it again right now...

I much prefer the B58.

I also prefer B58 after owning N55 equipped 335. B58 has many changes which make it a much better engine.

Better how exactly.... both motors make around the same when tuned... reliability at the early years of the B58 lean toward the N55....

B58 weighs 150lbs more

Stock 340i is .2 slower in the quarter vs 335i

Many design changes are discussed here:

In the end... they both put out the same power tuned... reliability goes to N55 .. that's alllllll that matters...

[FastF30]

The new G20 I'm expecting they made many changes to the motor...
