We may need on of these in FS, the Celera 500L (http://www.thedrive.com/the-war-zone/11571/unmasking-the-bullet-shaped-mystery-aircraft-after-it-reemerges-at-victorville) If it meets it's performance specs; 500 mph at 51000ft using aorund 30gph. It uses twin diesel propulsion with turbochargers and heat exchangers to a single pusher prop, etc., and is designed to be super efficient. You can see how aerodynamically clean it is just by looking at it. It looks like the modern version of the Learfan, which someone also noted in the comments there.
Here is a link to the first sighting of the plane (http://www.thedrive.com/the-war-zone/9343/what-is-this-mystery-airplane-photographed-at-california-airport-last-week). The link to the patents in the main article above reveal a lot of information on the design.
