Yeah not much to explain here, the engine wss taken from a Zeppelin and put in a production car... with no headlights, no safety, no roof and borderline bicycle tires. And the 200 in the name refers to its horsepower. It must've been absolutely TERRIFYING.
Ok so this might be cheating as its literally the first plane to fly under its own power but hear me out. Given it's a biplane with no seat, has a biplane canard setup, features a 3L engine that somehow only makes 12 horsepower and needed to take off on a set of rails (does that mean it counts as a rail speeder?) I'd say it's fair to call this thing... unique.
That's not a joke, this flying wing was designed to be road and air legal. Using a Studebaker engine it was rated for only 120mph in the sky but it was, nonetheless, a flying car. Studebaker was invested in the project but when narket response was tepid it never made it to production.
