BMW, or any car manufacturer, doesn't care about your need for tuning. If they can, they would make it impossible for tuners to tinker with the engine. If that's the overly critical aspect of an engine on this forum - its tuning potential, then yes, the N55 may be a tough nut to crack for the tuners. Still, as they say, if there's a will there's a way.

For it's supposed lack of advanced engineering, the N54 sure racked up enough engine awards.
Perhaps it's worth thinking of the N55 as bringing the best of the N54 (low end torque, minimal lag) and N52 engines (valvetronic) into one and then throttling it back to improve fuel economy and emissions. This would also allow it some tuning headroom for an M3 but I can't really see the same engine as in a regular 3-series being adapted for the new M3. |

I haven't seen ANY hpfp problems (knock on wood) and this car (335i w/ n54) is just perfect. I imagine the n55 being just like the N54 but minutely improved (peak torque @ 1.2k instead of 1.4k, 1-3 better mpg, etc)...but the biggest problem I see is the switcheroo BMW did w/ the turbo's and therefore TUNING. One of the BEST things about the N54 is its tuning potential (Unreal gains for peanuts). The N55 seems to be a tougher cookie from you guys' speculation. The next M3 is supposed to run a twin turbo set-up... I am making a lot more hp and torque and have been for a while for about a year (w/o any reliability problems) than a 335is. The N55 is gonna be nice, don't get me wrong....anything replacing the N54 will have to be! At the end of the day, given the choice between a N54 and a N55, I would put my money on the N54. It's just a dream engine...no wonder it has won international engine of the year 2 times in a row. http://en.wikipedia.org/wiki/Interna...ne_of_the_Year http://www.ukipme.com/engineoftheyear/ |

this set up might be easier to do a turbo upgrade in the future

First current N54 car to be officially announced with the N55 will be the 135i. It will be the only N55 offered with a DCT- no auto and yes a manual.

I can see any reason why 335i shouldn't move to the N55 with smoother power delivery thanks to valvetronic. |

Why are people saying the N55 with Valvetronic will have less mechanical complexity? Have you seen the valvetrain diagram of the N55 cylinder head? An extra intermediate shaft, extra intermediate rocker arms, extra springs and an electric stepper motor to control the indexing of the intermediate shaft. Should be 'added' mechanical complexity.

Here's an interesting thought: now that the 3's are gonna come with a single turbo...that's a heck of a lot more comparable to the new Audi S4, with it's (single) supercharger.

Just to put a spanner in the works this is from australian car news site with the 2011 coupe
quite different to the existing shape. Powering the new models are a range of 3.0-litre six-cylinder units, typical to those found in the current line-up. The 335i makes a comeback, although it loses a turbo and drops to around 208kW to make way for a new model, the 340i. The 340i will feature twin-turbochargers to muster a total of 268kW. The other petrol engines will be four-cylinder turbocharged units displacing either 1.6- or 2.0-litres. High-output diesel engines will also feature, under the Efficient Dynamics banner, with a 323d (152kW) and 335d (228kW) model expected. BMW expects most models to be fitted with the optional eight-speed automatic transmission complete with stop-start technology. At this stage it is rumoured that the M3 will lose its 4.0-litre V8, the engine to be replaced with a straight six, twin-turbocharged unit with direct injection developing 308kW. The engine swap not only cuts emissions, but saves weight too. Sharper acceleration is promised thanks to an upgraded dual-clutch gearbox (available only to M3 customers).
