Double progress: high achievement, high efficiency. In order to bring a fascinating driving experience with values consumed up-to-date in agreement, BMW developed a row six cylinder petrol engine with Bi-turbocharger, fuel direct injection and full aluminum crank case as world-wide first a car manufacturer. The conception of the turbochargers already makes a contribution for consumption reduction. Because the turbines consist of high-temperature resistant special steel and bear temperatures of up to 1050 degrees, can be done without the refreshing effect of a increased fuel supply. Straight ones under full load result from it noticeable consumption reductions.

The key function in the concept for as economical a handling fuel as possible comes however the High Precision Injection. The new generation of gasoline direct injection fulfills also in practice expectations set into it regarding economy, without thereby reductions would be necessary with the dynamic qualities of the engine. High Precision Injection permits a more accurate mixture dosage as well as a higher compression - ideal conditions for an increase of the efficiency and a clear reduction of consumption. This becomes possible due to the central placement of the Piezo injector between the valves. In this position the new injector opening outward can distribute the fuel conically and particularly evenly in the combustion chamber. With the development of the new row six-cylinder with Bi-turbocharger and direkteinspritzung BMW opens a new chapter for already an engine principle quite old in the reason. Nevertheless could only recently the 100. "birthday" of the turbo engine to be celebrated. In November 1905 of Swiss engineer Alfred Buechi to the patent announced loader

LOL..you're not serious? When you're starting in the low the 6 sec range to begin with .5 seconds is a world of difference.

Still, for those of us in the U.S., rumor is we will end up with a 3.5 liter instead of the bi-turbo 3.0.

I'm an engine novice. Where are the exchaust manifolds? Where are the mounted turbos on them? Thanks again, voltron1011.

Look at the first pic that fleet posted. on the left side of the motor you'll see alot of pipes (manifold). If you look closely, you'll see that every other pipe (six total) goes to one of two turbos. You can see one of turbos right on the front of the motor, and you can sortof see the other one at the opposite side of the motor.

This thread is expoding right now!!!!!

[tjalt]

Looking forward to this. Looks like it's time to trade in my Boxster!

BRAVO FLEET!!!!!!

Thanks. BTW, I'm keeping my day job.

Incase you didnt read the release bit I posted

Its 2 Small Turbos, each feeding 3 cylinders

[E90Fleet]

Here we go, side view

Yeah, it would make sense that they are small due to the relatively small desplacement of the motor (3.0 liters)

[voltron1011]

Fleet, do you know what the firing order is on this motor?

[E90Fleet]

Intercooler and Direct Injection nozzles

Turbo cars are nice but the turbo lag kills it. I would talk a NA engine over a turbo anyday. Do you know what a bitch it will be to replace those little fvckers

No real lag due to small turbos

[voltron1011]

I wonder what internal changes were made to the motor. Pistons, crankshaft, slightly lower C/R, better oil system?

[deadfresh]

Ha HA I called the intercooler back in December in the spy pics http://www.e90post.com/forums/showpo...8&postcount=10 !!! Another notch on my 335 predictions belt :rocks:

WOW Tine gave us the exact HP numbers weeks ago !!!

Seems whole block is Aluminium now

Pistons are different shape for Direct Injection

Fuel system now very high pressure for Direct Injection

But do we get it here, or is it NA for NA?

hello guys, german "auto, motor und sport" delivers under following
link

http://www.auto-motor-und-sport.de/n...der.104140.htm

a message regarding the presentation of a new 3.0 l six-cylinder turbo engine. it will be shown at the 76. genf autosalon from 2.-12. march 2006. this engine will, in the near future, first make it's debut in a new BMW-modell for the market(E 92?). other modells may/will follow. it seams to me "Tine" was well informend.
please forgive my bad english.

No one knows till BMW NA releases their specs
