I am not all concerned about the technology as long as the heat management is adequate.

I think the F80/F82 is all about heat management. If they can cool the oil and have it last through a track day then the car should be a success.
My concern is testing on the 'ring gives plenty of opportunity for cooling whereas most tracks in NA are shorter, slower and tighter. |

My guess is that IF we get 3 turbos it will be a sequential system with two small turbos in parallel feeding one larger turbo. This would generate power at a wider rpm range than three parallel turbos and allow for a higher useful redline.

Not sure why so much speculation on the turbo configuration. If it has 3 turbos they will almost for sure to be as per BMWs patent I posted just above.

This system would allow the usage of bigger turbos which wouldn't run out of breath at higher RPMs, (remember "near 8000 rpm") and also reduce, (possibly eliminate) turbo lag. I said it before and I'll say it again, I think we are going to see something new ! |

The reason to use a turbocharger vs. a supercharger is that it does not rob power from the engine in order to spin its turbine. The reason not to simply fix this by using a purely electric supercharger is that the energy storage required to power it would be very heavy. So, you combine the ideas by using an electrically assisted turbocharger (or system of them in some combination). |

Confucius once told me..."Cars with 3 turbos are better than cars with none"

BMW is always first out of the gate with ground breaking designs, whether it is aesthetics or engineering, BMW always takes the risks other manufacturers will not.
I have not been this excited in a long time about a new BMW model! |

The article referenced below states that electric superchargers use
"an electrically powered forced-air system that contains an electric motor to pressurize the intake air". What am I missing? Are these not used in production cars? http://en.wikipedia.org/wiki/Electric_supercharger |

They are indeed not used in any production car or truck that I am aware of. They may be used in some production engine for some application; that I don't know. I seem to remember reading about their use in either air or marine applications in the past, but I don't recall details.
But there aren't many production supercharged cars today anyway. Still, even if we look at aftermarket solutions of which there are a good many, I am not aware of any with electrical assist. Perhaps they were tried out sometime over the past 100 or so years. Today, though, no. Quote:

According to the latest issue of "Road & Track" magazine, they are planning to use 3 "tiny turbos" that will allow a quicker response than two small turbos or one large turbo. As another poster mentioned, the goal is to keep turbo lag to a bare minimum.
