This is the Pontresina, designed and actually built by Luigi Colani. This design was a concept for an aircraft that could raise the world speed & altitude record for piston powered aircraft. One thing you may notice is the unusual propeller design in the back, this is to get as much power out of the engine as possible without the tips of the propeller exceeding the speed of sound (this would have a significant effect on the performance). It's calculated top speed would be around mach 0.9 at very high altitudes.
