Cheaper to produce and potentially maintain. If they could, they would've put n55 with more power in the IS cars but the N54 performance kits have passed US and international emissions standards long ago...meaning they have paid their dues for standardizing it already. That just means they're trying to get the last invested drops out of this powerplant because it is cost effective and they don't need to pay to re-standardize an n55 with more power (it costs millions of dollars to do this). Car companies are being very careful how they spend their money these days. A little birdie already told me a stock N55 is out performing the N54 /w an oem performance kit on the track,,,45lbs lighter and more responsive out of the corners...not to mention it runs much cooler than an n54 :) Yowza!

I can say the N54 has a lot of potential ... but stock is not overrated at 300 crankshaft HP. Stock, my 135i recorded only 258 HP at the rear wheels. Add the JuiceBox3 tune, and other items, and it goes up from there.

I hope I'm making the right decision. Sounds good, because I just went out today and ordered a 2010 335xi Sedan. I hope I’m making the right decision.

You could still make the argument that the popular EU models are all underpowered (i.e. they sell a hell of a lot more 318's than 335s) Fair enough.

So I don't think this development tarnishes the Ultimate Driving Machine mantra. An EU market E38 728i was arguably underpowered, but was still a satisfying drive for an enthusiast minded individual. Big power is nice, and I certainly want my BMW to have an N54 rather than an N55, but big power isn't an essential part of the Ultimate Driving Machine recipe BMW has always offered varying degrees of power, and cost has been a factor in the content of the vehicles since the 1st Lexus LS400 debuted.

BMW is supposed to be the ultimate driving maching. But maybe now the M models and IS models will be, but not all of them.

I don't buy the excuse that "the N55 doesn't need two turbos because its single turbo is a twin scroll unit." It has to be a cost and weight savings thing, right? Because basically, all the serious BMWs are keeping the N54, and it's not just existing models - newly introduced serious BMWs are geetting the N54. It is also worth noting The N54's 300hp/300lb-ft numbers are widely thought to be underrated. I think I'm on pretty safe ground predicting that the N55's 300hp/300lb-ft numbers are not.
