Mein Auto: 335i
Just the facts mam...335is vs 335i

Hi all,

I know all the information I probably could ever need is on this forum already but I have searched and read for hours and still stand somewhat confused... Will some of you good people with true BMW knowledge help me make a decision?

I like fast cars. I like fast cars that corner well. I am sold on the E93 as the best car for me, my wife, and my two mini Australian shepherds that go everywhere with us.

I am a mechanic and can do almost anything that a car would ever need but I am 52 and just don't have the time or desire to mess up my hands modifying things and then fixing them because it didn't work as well as advertised.

So here are my questions...

Does the 2013 335is have problems with the turbo system and does it need to be walnut blasted every 50K miles to remove carbon?

Is the 7 speed dual clutch transmission on the 335is significantly better than the 6 speed 335i transmission? If so, what does it offer? Better passing? Better 0-60 times?

Why does the 335is advertise lower MPG's?

Can either model be modified with a "chip" and get comparable results or does one respond much better to chipping?

What is the BEST bang for the buck on getting more power without compromising dependability on either model?

Is there anything else that I should know about differences between these two models?

Thanks for taking your time to give me feedback.

All direct injected turbo engines are subject to carbon build up the rates may vary .
http://www.e90post.com/forums/forumdisplay.php?f=378
N55 engine may not build carbon as fast as the N54.

Same N54 engine as the 07-09 335i, so same turbos and direct injection. Therefore same potential issues with turbo failure, although I never experienced any myself, and definitely same need for walnut shell blasting. I believe the N55s have similar carbon buildup issues. No idea about how reliable the twin scroll single turbo is compared to the twin turbos though.

I went from an '07 335i to a' 13 335is, both manual E93s. Biggest differences for me are the overboost and the unique performance exhaust. The 'is normally has 332 lb-ft of torque but with the overboost, it kicks up to 370 for 7 seconds. Noticeably quicker than the base 335i. The performance exhaust is a specially tuned variant of the standard BMW performance exhaust. It sounds terrific, making the car sound throatier and angrier, without giving it that fart can sound. Also dig the burbles at low speed. I actually thought my 07 sounded pretty good; the 'is exhausted note is just that much better.

If you track your vehicle, the 'is had better cooling than your standard 335i. Finally, if for no other reason, I like the 335is because it's rarer and more exclusive. I think I read on this forum that there were only like 7000 made.

Well, good luck and happy hunting.

Total of 3396 E93 335is were made. There is a thread on the E90 site that has both the coup and Convertible break down.

I have had mine now for 2 years, love the car. The power is just right, the sound is fantastic with the top down and so far at 43k I have had zero issues.

Regards

I've had my is for two years and love it. Yes you'll have to blast the valves, any DI has these issues. I drove both the 6MT and the DCT and chose the DCT. Personal preference and my son has a 6MT Roush Mustang and we trade every so often so... Lots of tunes out there, I went with COBB but there are many good tunes on the market. You're going to hear about suspension upgrades and LSD. Both good ideas, a lot depends on what you do with the car and how much you want to spend.

The 335is gets worse mpg because it has the n54 engine which is less effecient than the n55 the lci (e92/e93) 335i comes with.

Mein Auto: 335i
Thanks to all of you for your comments and opinions! I appreciate the help. I am blessed to live 50% of the time near Estes Park Colorado so I drive a very winding road with few places to pass. However, with the 335is I figure those opportunities multiply by 3-4. I can't wait to truly test the car in the curves but my wife and dogs will be the limiting factor on that one

I hope to find out this week the outcome of my first purchase a few weeks ago (a 2013 335i). The dealer misrepresented the car on several items, the three serious (deal breaker) items 1. The car has been smoked in and slathering the ash tray with stinky oil doesn't hide the fact. 2. I was told in service date was Nov 2013 giving me several months of ownership with the factory warranty. However, turns out the warranty expired Feb 2017. 3. I was told that were no dents or damage to the car, yet the hood has two large places where apparently bird crap sat long enough to eat the paint away... Of course it is the first thing you see when you walk up to the car. Some other issues are present but I count the fact that my charge pipe blew off, resulting in me taking it into my local BMW dealer a blessing...that's how I found out the truth about my warranty.

The General Manager from where I purchased the car has assured me they will make me happy including buying the car back...

I will fill the community in on how this turns out with more details when it is all finished!

]I don't think there are significant issues with the turbos on the N54 engine, but you will definitely need to walnut blast it to keep it at its top performance.

I have a DCT and I believe it is better performance wise and you can probably do some research and find it somewhere. By better I mean it is faster and smoother than a standard auto.

]I'm not sure what the advertised MPG's are for each of them, but I would guess it isn't significant. Mine has a Cobb tune and putting down a good amount of hp that I use quite frequently and I still average between 24 and 25 MPG.

The N54 in the 335is can put out more power when modifying, but with $1K or so with a few mods both will be quicker than most things out there.

There are a few choices out there and some are more expensive than others for what you get out of it. Dinan, is most expensive and provides the least power. The others are MHD flash, Cobb, and JB4. Each of those are similar in what you get out of it, but provide various options that people have priorities for.

Like someone noted before, the 335is is much rarer and it sounds great compared to a standard 335.

Thanks RDkind62. My car of choice is black or blue like yours, preferably with the saddle brown interior or black...Nothing else will do and we will be getting the E93. I look forward to hearing the 335is exhaust because many have commented about it!

You'll enjoy the is exhaust note, my car is RD's twin without the intake and I really enjoy it. And you'll surprise a few people.

The 335is is a great car. I had a 335i and now the IS and would never go back. In terms of performance, DCT seems to be worth about 20% power increase. Look at the M3, M6 and 335IS and their drop in 0-60 times. It's very noticeable and you would need a notable gain in HP to get similar results if thetranamission Was constant.

I see you don't own a 335is and would not know the fun difference. If you 1st bought a BMW with gas mileage in mind then I think you might be looking at the wrong car. I would not even consider gas mileage even in the top 20 of reasons for buying this or any other sports car. With my car in drive I get over 25 mpg and when I leave it in sport mode it gets around 22-23 mpg and when I play with the paddles and like to hear the exhaust note, well 19-20 mpg is not too bad. Coming from a Z4 M Roadster that got between 18-20 MPG, 25 is pretty good in my book for a car that does that doing 0-60 in 4.6 sec.

Cheers

I own a 2011 335is but okay.

I obviously love the car, i dont care about the mpg difference between the n54 and the n55 i was answering his question as to why there is one.

I owned a 2010 m sport e90 335i before this so more than most i actually would know the differences between a 335i and a 335is.

Personally i get around 20-21mpg with the 335is but mine is a manual, i dont have the long ass 7th gear the dct gets that helps save plenty gas.

The exhaust note on the 335is will probably make u forget the 335i. Yeah you can get a different exhaust for the 335i, im just saying, the 335is is pretty special. Its certainly much louder than a 335i and has a lower tone to it at lower revs but as the revs climbs the pitch gets higher and honestly almost sounds exotic. How they managed to get such a dynamic exhaust note out of this inline 6? No idea but i love it.

Oh and youre going to love the subtle backfires at lower revs when getting off the gas. You'll hear plenty of it before you pull off the parking lot. The cracks & pops make me smile every time.

Just make sure you drive with the windows down so you can fully enjoy the exhaust because you wont hear much when the windows are up.

On the right hand side it says "Mein Auto" You show a 335i. Not a 335is. If you don't update your information, how is anyone supposed to know what you own?

FYI look again because it ain't "Mine Auto" but there are 2 things to note about it, first it is limited in size so if someone has multiple vehicles they may not be able to put them all in or may leave off some portion to fit another model in, and second as SayitaintTom wrote it doesn't show when using the app (so its very easy to forget about updating).

Considering your requirement for accuracy in others personal information...where exactly is Georiga?

Edit: Most important to the point of those posts in this thread, Mein Auto is irrelevant! By your reply since the OP's question is a comparison of 2 cars the only valid replies would be from someone with both models listed currently in their Mein Auto.

@2airishuman, you want sporty just stay away from xdrive then for your first mod ditch the run flats.

Let's be careful with terms here. So as not to scare any folks away, the 335is exhaust burbles...it definitely shouldn't backfire. As most reviews state, the exhaust is one of the best characteristics of the car.

To the OP, I've owned a 335i and a 335is, both with N54 engines. The 335i was mildly tuned and felt faster...it was also a lot lighter by virtue of being a sedan rather than a 'vert, as my 335is is. The 335is is a great package, and as my major modding days are in the past, I appreciate that the car is a somewhat rare factory tuner version that feels special without major mods. It's very good at what it is. If you're going to modify your car more than a tiny bit, get the regular 335i IMO. But try driving a 335is to determine whether it does it for you, stock.

Get the is with the DCT, and drive with the top down, you'll be glad you did.

+1, though black/black adds 100hp

Seats four, great on back roads yet comfortable in a crawling commute, quiet as a fixed-roof car, top goes down, quick, fun at the track (with only minor brake mods), hauls skis, super easily hauls my mountain bike with an Invisihitch and 1Up rack.

And I've hauled a 55" plasma and a huge table - separately - in the back seats with the top down. Not even a wagon would have done that.

A fun fact: The convertible's trunk is slightly larger than the coupe's. Of course, that's with the top up . If the top's down, just use the back seats!

There's nothing I want a car to do/be that this isn't good at. And that exhaust...

Oh the virtual HP wars are heating up

On my way to dinner with my wife, and the guy behind me at a light asked if that was the stock exhaust on my 335is. I said it was (I pulled the solenoid for the flap) and he said it really sounded great.

The exhaust is that good! Probably would bring peace in the middle east if everyone had an IS. LOL.

I can't wait to hear one of these! Tell me more about your solenoid and flap???

BTW Peace in the middlle east will only happen for about 7 years and you better know WHO you believe in when that happens...

Tell me more about your solenoid and flap

Search "golf tee mod" basically for many BMWs there is a solenoid that controls a flap near the exhaust tip. It opens up under hard acceleration (allowing exhaust gas to flow out both exhaust tips) I think but closes at low RPMs to keep the exhaust quiet (flow is though one tip). If you pull the controller cable (or the vacuum actuator and plug it with a golf tee) the exhaust is much louder on cold start up and sounds much more aggressive throughout the rev range. easy mod that costs $0, takes a few min to do and can be easily reversed.
