Quad bikes aren’t new inventions. They’ve been around for some time now, and there are many manufacturers — Honda, Suzuki, Arctic Cat, among them — that build and sell quad bikes. But we’re not here to talk about those quad bikes or all-terrain vehicles (ATVs) as they are otherwise known. We’re here to talk about a unique ATV, and it might as well be called the quad bike: the Engler F.F Superquad. While it does fit the profile of an ATV, the F.F Superquad is anything but a normal quad bike. It’s more like a mishmash between a motorcycle and a supercar carrying enough power to make other exotics weep. YouTube sensation Shmee found some time away from his busy schedule to check out the Superquad ahead of its debut at Salon Prive in the U.K., and, as you may have guessed, even Shmee found himself geeking out over this extraordinary vehicle.
