Not trying to hit on either, both are very good, agree with comments that the N55 is more economical and runs cooler. Another item to consider they had to raise the boost on the N55 to 9 , N54 is 8 or 8.5 if I remember correctly. |

The 60-mph-dash was a tenth slower at 5.6 seconds, while times to the higher speeds were improved (21.6 seconds to 120 mph beats the twin-turbo featherweight by six-tenths). That's impressive, especially if the fuel economy ends up equal or better." Read more: http://www.motortrend.com/roadtests/...#ixzz0xdbhkfkE Quote:

Are you unable to read or just pretending to? I said this engine will create a baseline/standard for the next generation M3. So, to answer your question more directly: I am 100% that the N55 will NOT be on the M3, but I am also very sure that a variation of the M3 will most likely be. Discussions regarding this have already surfaced.

All anyone knows right now is that the next gen M3 will be FI, though there are some indications that the F30 will be a bit larger than the E90/92.
Given the output of the N55 I'd be very surprised to see an S55, I don't see the M potential. |

Doesn't look like they tested the different engines back to back but seems like the N55 is the same if not slightly quicker. |

"How Does It Drive? Nearly identically to the N54-powered 335i: It’s fast, smooth, and extremely stable. With the announcement of the move to the single-turbo engine, enthusiasts (including us) cried foul. We believed the N54’s output had been underrated, and that the N55, although matching it in advertised output, would be weaker in reality. But all of that can be put to bed. Our 2011 335i was just as quick as the twin-turbo car, reaching 60 mph in the same sprightly 4.8 seconds. The quarter-mile flew by in 13.6 seconds at 106 mph, a tenth behind the quickest twin-turbo sedan we tested. After the century mark, however, the new mill picks up steam, reaching 140 mph nearly a full second quicker." For easy comparison with Motortrend's similar results I mentioned above Quote:

Both engines are great, it doesn't make sense to fight over 0.1 seconds.
Hopefully N55 is better in reliability (Not proved so far)

The n55 would seem to clearly have an advantage in power as indicated by the higher trap speed in the 1/4 mile and 1 sec advantage to 140. Remember this new f10'is almost 400 lbs heavier than the outgoing model and has inferior tires.

Run them at equal boost, then compare.

That would be pointless. The idea is to compare them in stock trim, if you read my post I didn't say the n55 had more tuning potential or was running equal boost to produce the same power. I simply said its making more power and thats hard to argue against looking at the numbers. Dont know what the boost is set at for either one but yes if indeed the boost is lower on the n54 then thats probably why its making less power but it does seem to be making less power.
That would be if you were comparing apples to apples. The new 535i with the N55 benefits from a new, MUCH superior 8 speed transmission. That is why the performance numbers haven't changed much despite the extra 400 lbs on the '11 model, not because the new engine is far more powerful. The C&D test drive on the new 3-series comparing the N54/N55 just a few posts above certainly wouldn't support the idea that the new N55 is so much more powerful on its own that it would propel a 400lb. heavier car to the same speeds as an N54... cuz 400 lbs is a lot, and the N55 doesn't have that kind of power advantage. The new transmission is far superior I'll grant you that but most of the benefit would come at the lower speeds where its quicker shifting and shorter ratios come in handy but top end would help much and might just equal out cause of extra shifting or longer top gears(havent looked at the ratios so it might not be any different) Either way the trans alone wont make up the 400lbs difference. |

Automobile mag finally did some tests and comparison between the n54 and n55. "And now to the N55: well, it doesn't, in fact, make as much power as the others N54s we've tested, but it does make slightly more torque. Peak numbers were 266 hp and 302 lb-ft. Before you start typing your "N55 sucks!" forum posts, let's remember that while the N55 put down 10 less horses than two of the N54s, a third N54 produced 10 more horsepower than the others. Meaning: 10 hp is within the noise when you're at this power level -- it's a variation of less than 4%. And you can easily see 4% variance between runs on the same engine." "The end result? We can finally and directly compare an early N54, late N54, high-output N54, and an N55. The N55 exhibits less turbo lag in normal street driving, and even though its peak output was near the bottom of the group of engines we've tested, it's still well within its rated peak horsepower output -- and well above its rated peak torque output. Let the N54 vs N55 war continue!" I guess some people's butt dynos aren't as great as they say. |
