335is Coupe & Cabriolet / New N55 Specs and Models Excluded

Gig103 · 01-09-2010, 08:10 PM

What the heck is a 335is? I will admit I have been away for a bit, but is that the same as having ZSP or ZMP?

is gets the dct and the added power if you want it.....

The 740 gets an uptuned version of the N54. The 740 has an uptuned version hence 40 and not 35. I don't see how the N55 with a single turbo could be better than the twin turbo N54. I am sure that the N55 is cheaper to manufacture.

GreenPlease · 01-09-2010, 08:36 PM

You know, I've been thinking about the argument that the N55 will be cheaper than the N54. Single dual scroll turbo is definately cheaper than twins but valvetronic has to add expense. A well respected engineer over on GreenCarCongress once said that valvetronic was "hideously expensive" and that assembling it was similar to putting together a swiss watch.

Better in what sense? Same power at a lower RPM, better fuel economy, less weight. Right...those sound like horrible things.

The only unknown is tuning potential, but for 98.99% of BMW buyers, the N55 most certainly is "better" than the N54.

i335i--Thanks for pointing out the typo 355 v 335... However, maybe we'll have to wait until the 355 LCI before BMW fixes HPFP

"enhances fuel-efficiency while increasing power output"

So would this mean the fuel mileage for city and highway would increase say 1,2 or 3 more miles per gallon?

mapezzul · 01-09-2010, 09:30 PM

I would hate to tell a lot of you that this memo- (For Canada) is not 100% accurate.

You can continue to speculate until 1/17 (E92/93) and 1/22 (for the iS).

Keep in mind that the 740 which was just introduced and set to debut in Detroit on Monday IS N54 powered and is not included in the memo,

And to all those saying the "iS" is the same as the current N54- boy will you get an eye opener when this car is actually on lots.

skimo · 01-09-2010, 09:35 PM

Is fuel economy calculated with weight in mind? In other words, is the increased efficiency due to the weight loss or are they independent?

Independent. 20kg has negligible effects on fuel economy.

N54 FTW! Two turbos will always have less lag than a single turbo. That's the whole purpose of the second turbo. Why BMW is going back to a single turbo is beyond me.. probably for cost savings.

tirana · 01-09-2010, 11:00 PM

What about emissions? There are other pressures at work here (California emissions, etc). Any new engine is going to slow down the tuners, especially if BMW keeps paying attention to thwarting (or at least detecting) after-market tuning. That's the price of new toys (not that there won’t be tune kits - they will just not be as mature as the current N54 mods).

Most people won't even notice the difference. It’s a turbo-charged, I6 putting out the same bhp/torque. Heck, many people still think the 335 has a 3.5 litre engine.....

Not relevant to this thread, but one of my friends (who doesn't know I'm a BMW addict) was describing to me his X5 test drive. He said the dealer told him there is a 3.0-litre model, a 3.5, a 4.4, and a 4.8. He said he wants to go with the 4.8 because presumably it's the most powerful. Forget his ignorance, why is the DEALER telling him the xDrive35d is a 3.5?

better mileage is great, now can they please just give the 135i a bigger engine

Why would they do that? The 1-series is the bottom of the barrel BMW.

fdsasdasdf · 01-10-2010, 12:17 AM

10% reduction in fuel economy?

amlebede · 01-10-2010, 12:17 AM

Wouldn't there be a bigger turbo lag?

vladberca · 01-10-2010, 12:25 AM

1 series will receive an iS version, as well, same engine from 335 iS... can t wait for the launch of these models

There will not be big differences between models equiped with the N54 and N55 engines, especially in the stock form (fuel consumption and performances, in general)...
I m just curious if the LCI X5 will have the N55 engine and X6 will remain with the N54 engine..

It says -1L/100km. Remember fuel consumption is not only measured by MPG; with L/100km (used by most countries around the world) it is better to have lower rating. As in 10L/100km is better than 11L/100km.

And it makes sense: you use 10 litres of fuel per 100km of driving, instead of 11 litres per 100km of driving.

haha, I meant bigger gas tank!!!

Here is why they are changing from N54 to N55. Apparently it was meant to happen the whole time.

"This has the same advantages as two small turbines (as on the N54); it's just combined in one housing (in the N55)," he added. BMW could have used a single, twin-scroll turbocharger on the N54 engine, Holder said, but company officials were concerned the quality would not have been up to par at the time the 335i coupe launched in 2006.

I think most people are missing the point. Firstly, in terms of N54 technical advance, it is not as good as the N52. One of why I and many people who love the NA engines are because of Valtronic which is not present in the N54.

BMW now can use Valtronic on the N55 engine, at the same time, it changes from a twinturbo setup to a twinscroll setup, which basically does the same thing - the twinscroll basically have two fans on the same housing where the smaller fan spool up first and than the larger (lots of information on the net). The fact that the N54 has two turbos doesn't mean it is better.

As someone mentioned before, the N55 would probably mated with the new 8 speed gearbox, which will possibly even make it faster. So, I do believe it would be an upgrade.

As far as the IS is concerned, it only make sense they have now tested the drive train with the updated 245kw N54, with DCT that they would stick with those setup for the IS versions, where they are either, a) not have enough testing done on the capabilities of the N55, or b) reserved the N55 twin turbo for the M1, where it will have valtronic, a twin scroll for everyday driving, and a larger turbo for higher end torque.

I know I am a bit speculative, but really, I think the N55 would be more than worthy as the successor to the N54.

The only disappointment would be from dumbo's ears for the 2011, and definitely not the engine.

Technic · 01-10-2010, 07:31 AM

I don't know who can be talking about a possible turbo lag with the N55 when the sucker's torque peaks at a measily 1200rpm compared to 1400rpm with the N54.

Between idle (800-900rpm) and that torque peak are just some 300-400rpm... any turbo lag that can squeeze in there must be some supernatural entity.
