Not trying to cast a damp spirit about (because I think this is an
awesome application), but there seems to be an issue at the moment with the general availablity of motors suitable for embedding in hubs. I know of a few projects that have gone back to a more 'conventional' drivetrain back-end on the drive motor to overcome limited torque and speed opportunities. I've had limited access to the vehicles but I think I get the gist of the issues these groups have had, if it helps.
I think the 'range extended' electric concept which Foersy describes is the way forward for this kind of technology, it's also the most accessible, and most proven, especially for 'niche' vehicle builders. It sorts the drive delivery out and then allows later upgrade of the gen-set, depending on how technology moves forward. At the moment the effectiveness and effieciency (and fuel availablity) of a fossil-fuel powered gen-set is unbeatable. It also saves having to piss about with thousands of pages of engine strategy! Toyota and Honda have spent billions trying to sort the issue, and they've still not got it right. However, what Foersy is going for is, well,
really workable.
I want to see this come to life! Best of luck, guys!

Oh, I also think their may be a few business oppotunities for Foers beyond their own vehilces.
