Actually, what you are looking at in terms of "reworked"
is a strengthened aluminium block with a heavily modified cylinder head , The Induction tech is completely all new as will be BMW's latest bi-vanos variable valve timing. EfficientDynamics plays a huge part in not only lightweight chassis and body panel technology. Engine Stop-Start , on-demand ancillaries operation and Brake Energy regeneration will give the all-new M3 20-25% better efficiency than the current V8. The First protypes of the BMW M4 Coupe will be seen later this summer.

I dont know what everyone is so suprised about, this is EXACTLY what BMW did with the new M5 and M6, so why is it a shock that they are using an existing block as the basis for the 'new' engine? If they did it for the top of the line M, no reason not to accept that the M3/M4 get to follow the same path, makes perfect sense in the new world of bmw

Man, stop whining about the engine and focus on the good - the car will be LIGHTER than the current version. Now that is a step in the right direction regardless of engine choice. Lets hope its something substantial though and not just 5kg less.

SCOTT26 says 20-25% better fuel efficiency. Sounds good on paper, but still not great. If I get 14mpg right now in my E92 M3, that kind of improvement will only yield me 17-18mpg. I would think an F80 M3 with a revised N55 could get to within 1-2mpg of what the F30 335i can get for fuel economy. |

Just the fact that power output will got from ~300hp-~320hp to roughly ~450hp suggests there is going to be some major modifications. In fact we already know that the engine will use at least two turbochargers vs. the single dual-scroll turbocharger employed by the N55. There may yet be a displacement increase to 3.2L also, though that remains complete speculation. We do know (or are virtually certain) that one M staple of the past - individual throttle bodies per cylinder will not be making a return. Like the new S63Tu, we can expect Valvetronic thorttle control instead. I also think we will see some innovative induction system employed to reduce turbo lag. Perhaps, just for example, we could see tri-scoll turbochargers being fed from 3 cylinders each. The much rumored electric turbo system may also make an appearance. There are other possibilities such as variable geometry which also eliminates the wastegate. Still plenty of time to speculate yet. |

Here is the BMW engine lineup, circa late next year: N13B16 N20B20 N55B30 N63B44 N74B60 "S55B3x" S63B44Tu The N52 is out of the picture when the E82/E88 die. In addition to what I say above there is the three cylinder in the i8 which will spread to other BMW models (and probably replace the N13 in the process). There is obviously the electric and hybrid drive systems in the "i" models and ActiveHybrid series models. Not to mention all of the great diesels. And finally, expect another new M engine (rumored to be N20-based) for sub-3 RWD M vehicles such as an M2. Lots going on here. Certainly no less than other recent times for BMW, and in fact with the "i" brand, much, much more. |

God, if those are the high points, I must not have been paying attention. Two cars that get 10 and 14 city mpg, weigh 3,600 and 4,000+ pounds, no thanks.

Hilarious! Only in Germany would a company trust that no one would break the rules and pull that thing off! ; )
The amount of crying in this thread, over a car that will outperform the e9x in every capacity, is so pathetic. |

Are you sure(?) ... according to my informations an N55 based solution would be an first off all cheap solution.

We should see the FEP F32 around August/September , The 3er GT is now in FEP so Bimmerpost photographers look out! I was at the manufacturing facility in Munich where they build the prototypes of new models on a seperate production line away from the production line. They are about to roll out the X4 and the BMW City Compactive now that the MINI is testing and the discombobulated-MINI ( the internal joke for the 5dr MINI ) which the entire side from the B-Pillar to the C-Pillar (including the rear wheelarch is the rear access door.

This very innovative charged-pulse system of the S63Tü only works on V engines, because it needs the cylinder outlets to be close together, so that the way for the energetic exhaust gases are relativ short before the reached the turbo scroll ... totaly impossible in any way to be adopted to an I6, where the distance between the first and the last cylinder is very long !!! |
