Beyond Porsche, Subaru has also made extensive use of boxer engines, with the Impreza being a well known example. Ferrari experimented with the flat engine design in the 1980s, with the most prolific example being the Ferrari Testarossa, which sported a flat twelve.
The flat/boxer engine and all-wheel-drive became standard equipment for mid-size and smaller cars in most international markets by 1996, and is now standard in most North American market Subaru vehicles.
