I know, I know there has been alot of talk of why BMW would take its biggest largest car, with such a big engine and make that into a hybrid. But I look at this as just the first of many cars, and if BMW can make it happen with this car, imagine how good it will be when the technology trickles down.
Regardless,
here is a technical PDF file on the details of this car: bmw_concept_7_series_activehybrid_gb_fv.pdf
