I hate to be the guy to say it, but this isn't an engineering novelty, it's duct tape. I was expecting to see a jet engine or turbofan used for driving the drive shaft rotation. Instead, this is just as novel as putting a jet engine on a dog sled. And it's not "street legal"...it'll fail inspection as soon as the inspection comes up, whether it "was built to look as if VW delivered the car this way" or not.
