^^ i heard its gonna be the new m5 enigne minus 2 cylinders

Shawn S

Well, the GOOD news is, the next M3 will be a V8.
The BAD news is that most of the rumors say that it will come with SMG only.

soon bmw will have no clutches, all smg's

BMW today released new details on its much-rumored N54 Bi-Turbo Engine. The motor is expected to appear in the 2007 BMW 335i and 2007 BMW 335ci (coupe). The engine has an output of 306 horsepower and maximum torque of 295 lbs.-ft (400 Nm). BMW said it has already tested a 3-Series sedan with the engine, and achieved a 0-62mph time of 5.7 seconds. BMW said the engine is relatively lightweight — about 70kg less than its 4.0-liter V8 engine. According to the automaker, the 3.0-liter engine has little or no turbo lag, thanks to two small turbos instead of one large one. Maximum torque is achieved between 1500 and 5800 rpm. What we know so far: BMW will show its new E92 3-Series coupe at the Geneva Motor Show along with this new engine. What's no entirely clear is whether this engine will make it to North America. Recent rumors suggested this turbo engine would be exclusive to Europe, and a different naturally-aspirated powerplant would drive the 335 in North America.

soooo..... BMW needs 2 turbos to make the same power as the IS350's NA 6-cylinder... now that's some engineering.

I'm disappointed, BMW.

Stapler

I almost think they just don't want to make a bigger block to compete witht he 3.5 litter engines,

The last engine they had that big was in the early 90's, with the exception of a couple super duper S serries m 6 cylendars. The only other times they have gone to torbo's was when they didn't have a engine to make more power in that platform, like the 2002 turbo and the 745i. This will still be less of a powerhouse than the M3, odd.

srika

I guess moving to 2 small turbos and lower displacement to make the same power as a larger NA 6-cyl just doesn't make much sense to me.. why? is there an advantage?

Stapler

i'm a bit confused too, i was just trying to say that mabee they didn't want to spend the money devoloping a new engine just to fill the gap between a small liter 6 and a 4 plus litter v8. So lazyness.

srika

I see what you mean...

ilitig8

They already make more with smaller displacement ala the S54.

Just another engine variety to fit between the 330 and the upcoming E92 M3. In any event it gives them a torquey 6. The biggest thing will be the area under the torque and HP traces which will be much bigger than the 3.5 in the IS. Bottom line this gives them another engine, with more torque than usual and a way to make solid power without stepping on the toes of the M series high RPM engines. Although I am not a fan of FI, it will be a tuners dream and I think it fits into the product line quite nicely.

srika

^^^^ good points. I think I see it better now.

hmm maybe it gives better MPG and with ECU swap, it might jack up hp like crazy..

ilitig8

Though I don't know how much they listen to tuners and mod happy consumers but it will be the easiest/cheapest BMW engine to get power from. The S54 for instance is so highly tuned from the factory you figure $100 per HP. It is interesting to see it may not come to the US, it apparently was targeted at Europe. In the E46 chassis the distance was huge between the 330 and M3 and they may be just trying to capture some sales to people who won't pop for or don't like the ride of the M3, plus it will allow them to keep the M3 coupe/cab only (if they choose) while giving the sedan crowd a much stronger engine option. In the end I doubt it will provide better fuel economy, plus it would be useable in most of the line as well.

phipark

Sure is a small intercooler

Can't wait

Kinda weird coincidence that the HP # is exactly the same as the IS350. I have a feeling they're underating this thing - when the street numbers come out I bet this will be way ahead of the IS350. I feel for Infiniti - they have some big numbers to fight against.

Infamous425

infiniti will be fine, the 3.5 vq currently makes what... 290 hp? i bet the next gen will have 320hp +

ilitig8

Agreed either a huge coincidence OR it is a shot across Lexus bow.

SeCsTaC

Anyone else think BMW's 0-60 rating of 5.7 second is kind of low?

srika

weird, indeed.. I dunno why but I wasn't even thinking about modding. This is very true, for all these years BMW owners haven't had much to mod on their engines - instead they have had to pray their engines don't blow - j.k. - either that or drop a 2JZ motor in - but seriously - this will give em a chance to do some modding.

mclarenf3387

BMW had a 3.6 I6 that produced the same power as the Lexus 20 years ago.

And like mentioned this will be the easiest engine to get cheap power from. I can see these flying off the lots when they're realesed.

goldmemberer

Funny how Acura/Honda doesn't even fit into the picture. I have full faith in them but they just don't seem to be driven to seriously compete in the sports-lux coupe segment.

srika

How right you are. And how easily I forget. It's pretty clear BMW has a different directive for this project.

Straight six and turbo charged .

gavriil

The rumor was 380HP from 3.2 Liters.

srika

^^^ well damn. Guess that was a bit optimistic. See, if this engine really did get 380hp, I would have been like, sweet. Maybe the 306hp is a temporary fib to keep the Lexus folks guessing...

gavriil

I think weight is their main issue at BMW...

gavriil

It's way thick though

goldmemberer

And more specifically, the distribution thereof.

The 335i will outaccelerate an IS350, with the "same hp figure." And handling really is not a question here. I just wish, even though I know this isn't gonna happen, that Honda will get slapped into shape and will throw a single, relatively small turbo on the J32. Not that we have any idea what that might do

Maximized

Who cares about the published HP? Anyone that cares about performance will do basic turbo mods and this thing will fly.

titan

That's what I thought.

titan

... That's what I here.

heyitsme

I dunno, this is a pretty ignorant statement imo basically because its been used so damn much by people with power level A car who are upset by Turbo power B car passing them by with forced induction and all they can come up with in defense is that they are still N/A.

2nd, I don't think BMW needs to prove their engineering abilities. Their 3.2 already makes more power than the new lexus 3.5 and if that was their intention, to outdo lexus of all companies with hp/l, it would have been done.


I don't feel for Infiniti, I pat them on the back because imo they are the reason this engine and the one in the Is350 even exist.

2nd I don't think Infiniti even cares about an order of power like other companies do, they're the type of company that would drop in an oversized v6/v8 into a g-series without any respect to the rest of the line just to make a point.

srika

damn, forgot how many BMW fanboys there are.

heyitsme

Gotta do better than that, cause that in itself makes no sense as a defense in this case.

srika

read page 1 - I already reasoned through the ignorance of my first post in this thread....

heyitsme

Think there was more to it for both sides of discussion, but whatever now. Page one sucked as far as answers, haha.

SM-4

A tuners dream. First I6 turbo since the supra. I forsee big single turbos in the future.

ilitig8

Low as in you think the number will be higher? Not at ALL if that is what you meant. BMW almost always rates their 0-60 time conservatively. C&D in November got 6.1 and 14.5 in a 325 with 215hp/185tq, so it would seem the 5.7 would be very conservative! The best thing the BMW gives you the IS doesn't is a third pedal.
