Here is a comparison for you. We just developed KittyHawk, a new model classic tube and fabric airplane like KitFox that uses 912iS Sport engine, has 2 axis auto-pilot, Moving map EFIS, ADSB-IN and OUT, side by side seating, a spacious baggage compartment (tailwheel or tri-gear). We are testing the tailwheel #1 right now. Its costs around $100k in this configuration. We used Oratex fabric from Germany that is supposed to save weight and does not require painting like STITS and has UV protection built in (but I would never recommend this fabric ever again, it looks like crap and the tape simply does not have the sticking power of STITS tape). I'd take STITS and paint any day over this fabric.
Anyway, this airplane is doing from initial testing cruise at around 92 knots (106 mph) at 3.7 GPH or roughly 60% power. At about 75% power, its cruises at 99 knots (114 mph) and burns about 5 GPH. These are all calibrated airspeeds.
This is a STOL airplane with wider cabin, taller cockpit and longer cockpit with bigger baggage compartment than its predecessor Apollo Fox. It takes off in about 90 to 150 feet to break ground depending on flaperon setting and technique used. So speed is not its end all desired aspect. Meaning we did not try and make it so it can go fast.
Just some perspective for comparison.
Now having said that, I can tell you we burned 5.5 GPH in the long cross country to Oshkosh and back on average in our gyroplane going about 82 - 84 knots (94 - 97 mph) with a 914UL engine in hot humid conditions in July/August. That's about 17.5 MPG, one up. At gross it drops down a bit. Our trike at same speed did the same leg and was always 1 GPH better usually 2 up.
At 65 knots (75 mph) cruise in our gyro with 912ULS we burned a pretty consistent 3.25 to 3.5 GPH of car fuel 2 up. That's about 22 GPH and that is about its best cruise efficiency balance.
