Not digging the tri-turbo concept...

If they wanted the staggered boost concept, wouldn't it have been easier to use a twin-scroll set up for the bottom 4 cylinders and a larger higher boost traditional turbo that kicks in about 3500 rpm and takes u to 7500-8000 rpm?

too many concerns here - overheating, robbing power off the crank, added weight, 3 intercoolers, another hpfp; very concerned about reliability, not to mention this is less efficient

I do wish the 1M had the E46s 3.2L motor...S54?. That would have been awesome and would have saved BMW even more money than developing the I6 TT, is my guess.
Haha! Syle opinions from someone with an Exige are about as valid as political opinions from a retarded infant.

Guys, have BMW confirmed anything around the brakes? The front looks to be a 4pot caliper, surely they would put something better?

The issue of S54 for 1M was not wieght but emissions, it did not reach EU5 regulation. As for wieght they could just have it recast in alu/magnesium instead of steel.

A 90° V6 with counter-rotating balancing shafts is as smouth as an I6, weighs more, but the engines being alot shorter can be moved more backwards for an even better weight blance.

It looks like M3 Sedan (F30), M3 Touring (F31) are coming, in adition to M3 Coupé (F32), M3 Convertible (F33) and M3 GanCoupé (F35). Even an M3 GT (F35) is possible. Well and then we are geting X3 M (F25) and Z4 M (E89) but not sure if with the same engine.

I want the sedan- so e90 right? Sorry I am a long time 1'er... need to polish up on the M's!

I won't be getting it new... always had new cars and I want to try a used car maybe... also for the bargain and possible experience. I figure by the time the new one comes out in 2013 (the tri turbo) the prices will drop for the e90 M sedan and I can snag one up in APW!

Why are people comparing Porsche 911 to the M3? A 911 is a $100k+ car. The M3 is a $65k car. COMPLETELY different price ranges.

M3 is a 4 seater, the 911 is a 2 seater. The 911 is a purpose-built sports car, the M3 is not a sports car.

And according to this news item, there is a lot of bad information about the engine in this thread. The engine will be an inline 6, 3.0 liters (not 3.2), and will be more of a race-ready N55 than anything else.

http://www.autocar.co.uk/News/NewsAr...aspx?AR=258632


As far as the direction of the M3 goes...I am much more interested in BMW shaving weight off of the car rather than putting AMG-like ridiculous powerplants in the cars. A turbo 6 sounds like an ideal engine, but it needs to be done with forged pistons, and not suffer from heatsoak issues like the N55/N54.

Indeed, the displacement is going to be of 3.000 ccm, as the engine will be based on the N55 and should be called S55. It would be 3.300 ccm if it were the V6 based on the 4.4l V8 S63.
We are looking at a 3.0l I6 S55 with Twin-Porwer Twin-Turbos with one Electric Turbo based on the 3.0l I6 N55 with Twin-Power Single-Turbo.
S55 is to get 450 PS in the standard M3 (F3X), that is 150 HP/l. For comparision:
Nissan GT-R (MkII): 3.8l V6, 530 PS, 140 PS/l
Porsche 911 Turbo S (997): 3.8l B6, 530 PS, 140 PS/l
Porsche 911 GT2 RS (997): 3.6l B6, 620 PS, 172 PS/l
McLaren MP4-12C: 3.8l V6, 600 PS, 158 PS/l

Actually, June 19th was the last day to order a e90 ///M3. You can only get one used or from a lot.

We'll see whose info turns out to be correct.

there is so much crap info (best way to describe it) floating around right now and I think its all just guesses that these magazines are reporting as fact from their "sources".

Left Lane News is saying 2 turbos, which I can see, but maybe thats just because the "tri-turbo" is really 2 regular turbos plus some electric device and BMW might still just call it a twin turbo (since turbo is exhaust driven).

as far as the actual engine and the report of an enhanced N55 engine, do you really think BMW would do that? I mean they did it for the 1M but thats a different beast, I could see them taking a N55 and turning it into a 3.2L and then adding two large turbos but that is still a completely new engine, not just an enhanced N55 (just my opinion). If in fact it is just a N55 with an extra turbo, 430HP like the article suggests, then they are going to lose a lot of sales to Mercedes and Audi, Especially if the price is the same or higher than the current M3, not many will pay $70K for a loaded M3 that is using a N55 engine with an extra turbo.

M5, M6, X5 M, and X6 M all use what could be described as an "enhanced N63". You may instead call the S63 and S63Tu a whole new engine, but that's all pretty subjective (though at leat the Tu adds valvetronic).

For the M3, it's almost surely gonna be an engine that is adapted from the standard I6. To me the important part is not how much M does to the engine, but how much power they get from it and how the car performs.

You may be right but that's what they're going to do.

Not very many car manufacturers develop engines for just one model these days.

Is there another car in the BMW lineup using the current M3 engine? There will be plenty of cars using the new M3 engine:

Immediate:
X3M
M3
Future:
X4M
M4 Gran Coupe
Potential:
M2 with one less turbo?
X1M with one less turbo?
3 Series with 1 turbo instead of 2? 335i in a few years with the 3.2L and one turbo with say around 350 HP, remember how the 330i went to the 335i right after the remodel.

Its impractical for everyday cars to use the current M3 setup. It was designed for the M3.

I'm not a fan of shared powertrains myself, but then again, the direction of BMW is kinda losing me anyway.

Three turbos, if that pans out to be true just seems like alot of complexity. And the more complex you make something they easier it is for something to fail at some point in it's lifecycle.

BMW does a lot of testing before putting a car out. They run the motors through many different conditions.

Only complex if you don't understand it.
