Since we've been talking EcoBoost, and it's turbo DI system, we should give some credibility to BMW's new I4 turbo.
http://www.bimmerpost.com/forums/showthread.php?t=477882
Not sure where the original press release is, but it's interesting.
So now we have a high strung, twin scroll turbo 2.0l I4 replacing a 3.0l N/A motor for BMW.
Let's continue this discussion.... 
Note- the same reasons for the WHY's on the EcoBoost and the Hyundai 2.0l Di Turbo are applied to this new BMW engine.
I wonder if it will find its way into a 1 series chassis with an M on the trunklid.
{Place witty saying here}
I wonder if that is the motor that SAAB has contracted to use?

I would be stunned if it didn't.
For that matter, with BMW getting back into DTM, I wonder if there will be a major shift in that series away from the big engines, to smaller turbos.
I would be stunned if it did. The new 1 series checks in at over 3400lbs.
BMW is currently only tuning the 1 M 3.0 twin turbo to 335hp.
A 245hp in a 3400lb BMW "sports sedan?" That sounds really, really dull.
The 1M or whatever they actually call it will have the corporate twin-turbo 3.0 i6: http://www.1addicts.com/forums/showthread.php?t=463733
I wonder if it could find its way into something with a "2002" on the trunklid...?
They would probably tart up this for a M-series'd 1.
-Whoops . . . Stand corrected by Pigeon's link . . .
The whole M Series line is supposed to go turbo . . .
-=PJ=- "Oh FFFFFFFUUUUUUUU . . ."
I bet this would go rather nicely in a new 318i. 2 door 3 series, 2+2, RWD, 6 speed manual, ~2600lbs, this engine tuned to about 225-250hp, lift the suspension off of one of the hotter, bigger, non-M 3 series cars, could be a fun little car

Yeah... it's nice to dream... but I fear that is what a 2600 lb BMW will be - a dream. 
A 2600lb BMW has been a fantasy for nearly 20 years.
Even the vaunted E30 M3 weighed in at 2800lbs.
In reply to z31maniac:
stock mine weighed 2918# at a dragstrip years ago with half a tank and its 170# driver, so i suppose its what you'd consider a base weight, full tank or not.
but yea i'd be amazed to see any new normalish bmw weigh less than 2700# ever again. but here's hoping

I'm sure it will be the definition of reliability, affordability and low stress.

I knew somebody would bring the e30m3 up.. and unfortunately the same fanbois.. that is the exception to the rule because it was meant to be a race car.
Personally.. I love 4 cylinder cars.

The inevitable comparison: Audi Comparing this engine to the 2.0T FSI used by Audi/VW, that engine produces 211HP. This translates to the BMW engine producing about 34 HP over the Audi and can propel the X1 to 60MPH in 6.1seconds while the 2.0T in a larger A4 can only achieve 6.4seconds, a gain of 0.3s.
GM has had a 2.0, direct injected, turbocharged 4 cylinder since 2006. Since 2008 there has been a 290 hp, 360 ft lb version of this engine that carries a 100,000 mile warranty. GM is also definitely not the only person in the party, just using them as an example. About the only thing impressive about BMW's new setup is that it gets pretty good fuel economy.
I must say, I'm hooked on direct injection with a modern turbo...just absolutely awesome driveability from relatively low displacement. However, seems like BMW is about five years behind, which is probably why they're not making too much fuss over the powertrain itself.

So no real comments about a very high stressed turbo I4 replacing an already high stressed I6. BMW is known for thier high performance engines, and now they are downsizing and trying to keep up with previous power or torque targets.
And no comments that BMW should have put the development money into the I6 so that it would get better economy?
Interesing that this crowd will allow BMW to get a free pass on that.
Just sayin.
In reply to alfadriver:
They didn't create giant media hoopla saying it is more reliable than the previous motor.

300hp/335hp TT I-6 is stressed?
The previous M 6 cylinder was 3.2L, turned 8k rpm and made 333hp. Certainly that is more stressed than the turbo motor?
A 245hp turbo 4 doesn't seem that stressed. My Speed3 is 263hp and the same engine was tuned to 280 in the Speed 6, the GM motors mentioned before.
I don't think anyone is giving BMW a pass, but I know I don't care, because I'm not planning on dropping the coin on a new BMW.............well ever.

They don't have to, since the general consensus is that they are brilliant. Even if they are not.

Maybe Ford needs to market the ecoboost truck as "The Ultimate Towing Machine"

What's funny is that a 335hp 3.0l engine isn't considered stressed, but a 365hp 3.5l is. What's up with that?
The BMW is no more stressed than the EcoBoost, GM, or Hyundai, that's my point. But many take great joy in pretending that some of those are horribly over done in replacements.
they are all the same WRT the change. If the EcoBoost is "zomigodhorrible", then probably the BMW, GM, and Hyundai whould need to share the same opinion.
As for dropping the coin- piont taken, but I also doubt that many here will be buying a new Ford Pick Up anytime soon.
Seriously though Alfa, getting people to accept a turbo 4 in a sports sedan isn't as big a stretch as a twin turbo 6 in a giant truck.
