Looks like we would need something that looks like a stretch Vari-Eze - one of Rutan's early designs.

This kind of efficiency for a four-seater carry heavier than FAA-standard passengers screams for four-place tandem seating, and the minimum wings necessary to meet the takeoff requirements.

Needless to say, a diesel engine is needed for this kind of fuel efficiency.

The speed requirement is slower than a Cessna 172 or Piper Cherokee 140.

The requirements give us an insight to the rigors of aircraft testing. Car guys are not that rigorous. Maybe we should be.
