Ferrari is not the first to dream up an oval-piston engine. Honda actually raced and later sold an oval-piston V-4, with each piston having two connecting rods and eight-valve heads. Essentially, it was a kind of V-8 with two pairs of conjoined combustion chambers on either cylinder bank. AutoGuide uncovered a new Ferrari patent for a very different type of oval-piston engine, a V-12 with pistons rotated 90 degrees from their orientation in the Honda image.
