For an electric, adding all-wheel drive is a whole lot easier. I assume Fisker Karma is still being
fitted with PML Flightlink in-wheel electric motors. I assume Tesla avoided those because of cost
considerations, but I have no word of that. Inwheels should provide for the best performing traction
control and the Flightlink motors weigh no more than your standard disk brake system, providing for
zero weight costs electric motors. I'll try to verify Karma's use of Flightlinks.
PML Flight Link has never been discussed for the Karma and the company doesn't even still exist.
Yes you're right dpeilow; I believe Fisker is using in-wheel motors from a military application (can't remember the name at the moment). PML Flightlink did build an electric Mini Cooper using their technology as a demonstration piece (http://www.caranddriver.com/news/car/07q1/pml_flightlink_electric_mini_cooper-car_news).
