It was spotted with bigger/ better brakes already, the engine is in the "fine tuning" phase of development, so no worries for the moment that the next model will not keep its crown

Truth. People seem to have gotten so complacent with the S65 that anything less than 8 cylinders is deemed "week".

BMW needs to take notes from Vishnu. A good tune with a big single should be putting down around 550 RWHP and around 500 foot pounds... Is anyone taking odds on n54 vs n55 for the new M3 considering BMW put the n54 in the 1M and the 335is over the n55? Unless they did some major upgrades to the n55 and if so, I doubt they would keep the n55 engine code. Any thoughts?

I seriously doubt the veracity of some of this. What will be common with the n55, the block alone or a bored out version of the block with larger displacement?? Probably almost all internals would be different. It is terrible marketing and the car has a much poorer chance of success if it is called an revamped n55 or if that is actually what it is. There is simply no way they will lightly tweak the n55 change the boost and call it a day. As stated earlier the n55 share a ton with the n54 and that engine is too old to be reusing that much of it.
That being said the poster about 3 engines for the entire line up is correct. Well maybe the number is not 3 exactly but this is BMWs plan - massive reuse of common components for many more models. This is their road to much more profits. Pure and simple. Now at the same time I fully accept the veracity of the rumors that the car will have a relatively low CF content. I've been strongly promoting that argument here in this thread.

I would ask some kids to sneak in and pull the tarp off. Can't get angry over some innocent kids right? Take some photos and rewards the kids with ice-cream. LOL but of course I'm no were near and have no idea which museum.
Revised N55? I hope it revs higher! A little disappointed that we won't get light weight CFRP parts on the next M3.

I'm confused. Why are they displaying the F82 and not the F80 when the F32 hasen't been presented yet.

idk why everybody is so upset about the N55 block being used for the f80. It's a fine engine and it will be different. Turbo is the game right now and they will heavily modify the entire turbo system (from intake to exhaust). It will prob have a linear power curve all the way to 7K to mimic a NA feel in the upper revs, yet still have the flat torque curve from 1500-5000 rpm. Remember, this is a production sports sedan/coupe, not a tuner. I guarantee it's not going to be running some crazy high boost number, which will allow the car to make repeated runs.

All you need to bring the N55 into the needed hp-numbers is to re-inforce the engine-block and crank-shaft-housing to withstand the higher pressure of an bigger turbossystem, that is needed to reach the hp-numbers. So they would simply put struts on the outstide of the crank-shaft-housing of the N55 to make it stronger ... and then add an turbo big enough to reach the 450hp margin ... this could be an single big TwinScroll-Turbo, two Standard-Turbos or an modified N57-S TriTurbosystem ... I would put my money on the first or the third alternative, because an BiTurbo on an I6 donīt allow the use of BMW favored TwinScroll-Turbosystem. And to reduce the big lag of such an big turbo BMW would use the patented eTurbo-System to drive the turbos at low rpm ... to create an N/A feeling. This is simply the cheapest way to make an I6 turbo engine with ~450hp and probably the way BMW (not the M-GmbH!) decided to go ... if Scotts Infos are right ... and only marketing would quotes this as an heavily modified N55. But for me ... "heavily modified" meens, that only the pure engine block layout comes from an standard AG-engine and all other parts are unique to the M-engine ... like it was the case with all M-GmbH engines before the totally unique S85/S65 engines. Greets Uli_HH P.S. ... but I have still some hope, that Scott isnīt right in this case and we get again an totally unique M engine in the F8x ... I know an new statement from an internal that we shouldnīt be afraid of the engine and that the current opinion in the internet and statements of an BMW US-official are not right. |
