Uh, no... (

) I'm a FoMoCo MoFo. I'm a Global Subject Matter Expert in Design Efficiency and Global Product Development/Cost Process. Before that, I was a Research and Advanced guy doing off-board test software for our Fuel Cell Vehicle, before that a Vehicle Dynamicist. Those days were fun. Jackie Stewart nearly made me crap 'em doing some Transit testing one day.
One of my former mentors was Ulrich Eichhorn. He's at V-dub now (update: Ulrich bailed from V-Dub in '012 and is now part of VDA, the German Industry Board - guess he got out while the getting was good). I wonder what he's doing over there? Probably getting ready to take a bite on a big crap sandwich...
In any case, I always love it when outsiders start talking about things of which we in the industry are unaware. Don't think, btw, that we here are unaware of anything currently out there on the market - don't even assume we don't have a pretty good idea of what they (the competition) are working on.
See BMW TurboSteamer for a technology near and dear to my heart. I did a lot of research and cycle-mapping on that one. It's not a patentable architecture, mainly because the FE improvement potential of it has been demonstrated since about 1978 (Thermo Electron). F1 uses it currently - calls it KERS.
