The BAD news is that most of the rumors say that it will come with SMG only.

BMW officially announces new N54 Turbo Engine
BMW today released new details on its much-rumored N54 Bi-Turbo Engine. The motor is expected to appear in the 2007 BMW 335i and 2007 BMW 335ci (coupe). The engine has an output of 306 horsepower and maximum torque of 295 lbs.-ft (400 Nm). BMW said it has already tested a 3-Series sedan with the engine, and achieved a 0-62mph time of 5.7 seconds. BMW said the engine is relatively lightweight — about 70kg less than its 4.0-liter V8 engine. According to the automaker, the 3.0-liter engine has little or no turbo lag, thanks to two small turbos instead of one large one. Maximum torque is achieved between 1500 and 5800 rpm. What we know so far: BMW will show its new E92 3-Series coupe at the Geneva Motor Show along with this new engine. What's no entirely clear is whether this engine will make it to North America. Recent rumors suggested this turbo engine would be exclusive to Europe, and a different naturally-aspirated powerplant would drive the 335 in North America.

soooo..... BMW needs 2 turbos to make the same power as the IS350's NA 6-cylinder... now that's some engineering.
I'm disappointed, BMW.

I almost think they just don't want to make a bigger block to compete witht he 3.5 litter engines,
The last engine they had that big was in the early 90's, with the exception of a couple super duper S serries m 6 cylendars. The only other times they have gone to torbo's was when they didn't have a engine to make more power in that platform, like the 2002 turbo and the 745i. This will still be less of a powerhouse than the M3, odd.

I guess moving to 2 small turbos and lower displacement to make the same power as a larger NA 6-cyl just doesn't make much sense to me.. why? is there an advantage?

i'm a bit confused too, i was just trying to say that mabee they didn't want to spend the money devoloping a new engine just to fill the gap between a small liter 6 and a 4 plus litter v8. So lazyness.

Just another engine variety to fit between the 330 and the upcoming E92 M3. In any event it gives them a torquey 6. The biggest thing will be the area under the torque and HP traces which will be much bigger than the 3.5 in the IS. Bottom line this gives them another engine, with more torque than usual and a way to make solid power without stepping on the toes of the M series high RPM engines. Although I am not a fan of FI, it will be a tuners dream and I think it fits into the product line quite nicely.

^^^^ good points. I think I see it better now.

Though I don't know how much they listen to tuners and mod happy consumers but it will be the easiest/cheapest BMW engine to get power from. The S54 for instance is so highly tuned from the factory you figure $100 per HP. It is interesting to see it may not come to the US, it apparently was targeted at Europe. In the E46 chassis the distance was huge between the 330 and M3 and they may be just trying to capture some sales to people who won't pop for or don't like the ride of the M3, plus it will allow them to keep the M3 coupe/cab only (if they choose) while giving the sedan crowd a much stronger engine option. In the end I doubt it will provide better fuel economy, plus it would be useable in most of the line as well.

Kinda weird coincidence that the HP # is exactly the same as the IS350. I have a feeling they're underating this thing - when the street numbers come out I bet this will be way ahead of the IS350. I feel for Infiniti - they have some big numbers to fight against.

Agreed either a huge coincidence OR it is a shot across Lexus bow.

And like mentioned this will be the easiest engine to get cheap power from. I can see these flying off the lots when they're realesed.

^^^ well damn. Guess that was a bit optimistic. See, if this engine really did get 380hp, I would have been like, sweet. Maybe the 306hp is a temporary fib to keep the Lexus folks guessing...

I just wish, even though I know this isn't gonna happen, that Honda will get slapped into shape and will throw a single, relatively small turbo on the J32. Not that we have any idea what that might do

I dunno, this is a pretty ignorant statement imo basically because its been used so damn much by people with power level A car who are upset by Turbo power B car passing them by with forced induction and all they can come up with in defense is that they are still N/A.
2nd, I don't think BMW needs to prove their engineering abilities. Their 3.2 already makes more power than the new lexus 3.5 and if that was their intention, to outdo lexus of all companies with hp/l, it would have been done.

2nd I don't think Infiniti even cares about an order of power like other companies do, they're the type of company that would drop in an oversized v6/v8 into a g-series without any respect to the rest of the line just to make a point.
