Try again this time read the article before before spouting off miss information

What’s unusual is the number of boosters planned for the future M3. The rumor mill says three: two conventional turbochargers plus one spun by an electric motor in lieu of exhaust gas.

Nothing about the clutch is mentioned in the article.

The alternator is programmed to charge the battery primarily during deceleration. This relieves the engine of the charging load, which, in conjunction with additional electrically driven accessories, yields a worthwhile mileage improvement.

Further evidence of BMW’s enthusiasm for electricity is an experimental thermoelectric generator shown at last fall’s Frankfurt auto show.

[QUOTE]Sound hybrid-pricey? Supercapacitors are generally more expensive to make than batteries, but costs are coming down. Mazda's system comes as part of a big $2600 tech package on a $27,000 Mazda 3, so it's safe to say the supercap is ready for the mainstream.How electric superchargers went from fantasy to feasibility[/QUOTE ]

I don't mean to be upsetting , but you are a well respected member of the Community whose options matter, and up to now were taken as well informed. When you stated a reference a link as a sorce for information that has . No bearing on your information stated as fact, in fact it is the agreement for what we are trying to get past the Idea Stage is feasible. And as a well respected mimber of the Community request that this doable idea be moved to the Unicorn Coral with contradicting citations as evidence. This as quoted from in Hyperlink #17

"This is the technology that takes electric supercharging out of the realm of snake-oil fantasy and into legitimacy."
How electric superchargers went from fantasy to feasibility

as stated in same article in the past these things did belong in the Coral . Now with current technology it no longer is unobtainable.
