It’s no secret that car manufactures road test their vehicles in the public domain. To keep their worst kept secrets, well, slightly more secret they’ll generally finish the car in a vinyl covering or some sort of atrocious paint job. Fortunately, that has never fooled anyone and good thing, because if it did we wouldn’t have this video of the BMW i8 prototype electric/gas hybrid vehicle being tested in inclement weather (i.e. snow). Donuts aside, which is what you’ll see in the above clip, the i8 can supposedly achieve 87mpg, though that mileage will no doubt very with acceleration, traction and tomfoolery.
