I was looking at the coupe numbers, not sedan (which neither of us specified).

So, we're both right. :) Plus, the coupe is better looking. ;)

that says 49.6 / 50.4 on the manual and 50/50 on the auto.

335i on the other hand is

51.1 / 48.9 and 51.5 / 48.5 http://www.bmwusa.com/Standard/Cont...atures_and_Specs/335iSedanSpecifications.aspx


thats why people say the new 328 handles better than the 335

Over 1%? I seriously doubt it.

Same kind of people that whine about leaf springs and pushrods when they wouldn't even know if they weren't allowed to read the brochure.

Oh fawk what about when you are "at the limit 99.99999546885316886477%????"

Spoken like a true ignorant snob. I've made plenty of cocky snots like yourself chicken out and back off in corners while I sail through. They lose that smug grin fast when I'm right on their ass mid corner on and off the throttle making sure they are aware they arent going to "lose me in the twisties". :rolleyes:

I've also gone sideways hard enough (on purpose) to lift the inside rear wheel while the outside rear dug in and tried to pole vault me, I'm not ending up in a ditch any time soon.

Not that its relevant to my comment thats its bullshit that someone, random Joe consumer no less, can tell a 1% weight bias difference between two BMW models on the same chassis even and claim it handles better. I call bullshit. 335i will destroy a 328i all day long. A 1% shift in weight is statistically meaningless and any claims otherwise are a placebo effect from arm chair paper racers with prior knowledge of numbers on paper.

Youre basically saying taking a seat cushion or head rest from the rear and tossing it in the passenger front foot well will make the car handle noticeably worse. :rolleyes:

Your type of BMW fanatics have an unhealthy obsession with that 50.0000000000/50.0000000000 metric. Ill take the car that is faster both turning and straight over the slow one with your holy grail 50/50 weight bias that looks cool on paper to a computer nerd.

thats idiotic.

if you can see the numbers and are going to buy one anyway, wouldn't better weight balance be a "pro" in the why i should buy this item checklist.

doesn't that make you the ignorant one?

if a car company offfered the same car with 2 different engines. but you didnt know what the HP difference was for the same price. lets say one engine had 30hp more. on a test drive you probably couldn't tell the difference.

an "ignorant slob" would not have looked up there was a difference and may pick the one with 30hp less. why does he care he couldn't tell the difference on the test drive right?. someone who actually was not ignorant would have looked it up and picked the one that has the better specs all else being equal. why wouldn't you? not being ignorant would be the person who knew the specs even if they really couldnt tell the exact difference. hell maybe you are buying a new car, and used to drive some piece of shit. every car would be better than your current car, but you still want the best new car you can get even if you don't really know how much better it is than other cars like it. thats what informed non ignorant people do.

hell and in the case of the bmw the one with better weight balance actaully costs less , though it has less power than the more expensive one. so i guess any difference is not worth considering unless you are aa professional race car driver or something.

i never said a 328i was a better car than a 335i. i just said it probably handles better because it has a better weight balance. i'd figure for some people that might actually be a small positive for the 328i.

now if the 328i could be bought in both a turbo 4 with better weight balance or say a equivalent powered 6 (what this thread was about the i-6 n52 engine, though it got kind of derailed by the turbo 6 talk) with worse weight balance, well which would is better? probably the one that tips the scales. just like the 2012 vs 2011 528i. you got better weight balance for free with the 2012 and more power. it would be a definite positive.

and i guess since you are a mustang driver

i guess ford must be completely retarded then for putting that IRS in the 2015 mustang. or that they will offer both a v6 AND a 2.3 L i-4 turbo which will weigh less and give better weight balance. the exact same thing we are talking about.

now you'll probably say a real mustang has a v8. but lets pretend now that you have to buy a 2015 mustang and it can't be a v8. hell to not offend "real mustang drivers" lets pretend they rebodied this car, and called it the ford probe. you can get one with a 2.3 L turbo 4 or a 3.7 L v6. the 2.3 L turbo 4 will have probably 1-2% better weight balance better fuel economy and probably have more torque and lower rpm or slightly more HP or something like that based on the rumors. i'd get the turbo 4. i might not even be able to tell a huge difference during the test drive, but why would you go with the v6.

So you "probably can't tell the difference" of 50-100 HP but you can tell a difference of 1% weight bias, both on the same chassis.

Wow I've heard everything there is to hear in the internet now.

Gotta love arguing car performance in numbers less significant than rounding errors

I love the Mustang assaults even when we are talking about 328i vs 335i, shits hilarious. God the M3 must suck worst of all, its heavier than both 328 and 335!

I should be looking for a 318i for my next beater instead of a 2010+ JB4 N55 335i, its lighter and therefore better! 335i has .039711100009% more weight over the front axle, sucks and handles like shit :rolleyes:

Yeah Ford is retarded for putting IRS in my 2003 even! Added 70 lbs and ruined the handling and weight distribution omfg!

But the beef will dry out and weight bias will shift back to 50.01/49.99 and put you in a ditch!

The strange thing about BMWs is they're purposely set up to NOT handle well. The front struts are specced for 0 to -1 degree camber and there's no camber gain. The understeer actually scares me now that my wheels are aligned and I have good shocks and can actually get to the real limits of my E36.

Street car is street car.

My car has bad understeer due to me having Nitto 275 street tires on front and 315 R comp Mickey Thompson drags on the rear. It was designed for symmetrical handling with the stock power with 275s on all 4s, I threw that right out the window.

I like it, keeps me out of hot water. I can push hard and the front starts to break loose before the rear in a very predictable progressive chain of events. Throttle in a turn and the rear tires are like "nope" and pushes the front against its will.

But see I'm not ignorant and blaming the car or manufacturer, because its a result of what I have done to it.

Also you would look retarded running -3-4 degrees camber on the street while sipping a latte at 35 mph.

Cool none of my cars have "ox cart" axles. Neither does a 335i. So why are we talking about them again?

Same car, 30hp more and you can't tell the difference? But you can tell the difference between 1% weight distribution?

Exactly.

Crap I put groceries in the front seat and ended up in a ditch! Should have got a 328 instead of a 335.

For what it's worth the F30 328i has been tested as faster around Laguna Seca than the F30 335i in the hands of the same pro driver, and the commentary I've read is that the 328i handles better. Obviously your mileage may vary, and on the road I don't think there's much question the 335i would generally be faster.

Thanks idiot mustang owner for derailing a conversation that started off being one about naturally aspirated 6 cylinder engines vs a turbo 4 of approximately equivalent HP.

That we could not have a nuanced argument about the benefits of one or the other because you have the reading comprehension ability of a toddler, oh wait I give you too much credit a retarded toddler is unfortunate.


I never said the 335 was a worse car I just said having an inline 6 affects the weight balance and used the 335i spec sheet to show the difference in balance. Some people can't pick this up.

I think a shift of 2% probably would be noticeable, because you're shifting that 2% to the other axle, so the total change is more like 4%. The front axle loses 4% of its weight and the rear gains 4%. Wait, maybe that amounts to an 8% change...

Except there wouldn't be a 328 4cyl with the same power as a 335 6yl. That's just dumb. The 335 will always be significantly more powerful with an insignificant weight change, unless you're fond of compaing new X to old Y, which is also dumb.

Lol again at foaming in the mouth over Mustangs again. You two started talking about Mustangs, not I.

I started out calling bs on "noticing" 1% difference in weight bias between BMWs and you guys went on a anti mustang crusade. :rolleyes:

Which is hilarious because I have the one "mustang" that even die hard M3 enthusiasts respect.

Actually, as is typical, you were the first one to make some snide comment. I just called you out on it, as I will always do. I don't know why you insist on bringing it up considering it was very clearly proven that ox cart axles are ONLY used for money saving purposes in the thread I made about this very topic.


From post #30 "Same kind of people that whine about leaf springs and pushrods"

Yup. The same kind people that wouldnt notice the 1% difference until they saw it in the brochure, same people who like to regurgitate what they heard on Top Gear.

Also leaf springs and pushrods? 404 ox cart axle not found. You brought that up on your own.

Also that's more relevant to Corvette anyway, not Mustang, why did you bring up Mustang and ox cart axles exactly? :awe: I just listed leaf springs and push rods as popular crying points as other examples of things people think matter, except they don't, and those are the same type of keyboard racers that think they can get into a street car and instantly feel the dramatic difference that 1% weight bias causes...

I dare you to say I'm derailing as you "snip" everything out of my posts that is actually relevant to the thread, the part about 328i vs 335i.

..... Honestly I think it's pretty tough to legitimately derail an AT garage thread unless you say m3. It's sort of a different venue than elsewhere in the forums, we usually end up back on topic even if there is a side conversation.

All that matters to me is I've been window shopping JB4 N55 335i's , not 328s :awe:

I like the M package too. Rear bumper blackouts look so much nicer . Get the M styling with the better engine.

Not because its smaller lighter turbo engine making same power, but because it has more power potential period for less cost, like most factory blown engines. And I already have a 4 cyl and a 8 cyl so... I want a turbo I6...and I won't park a Supra in the rain nor does it have 4 doors for beater status so BPU 335i it is.
