Key Takeaways
- Calculated consistently as speed divided by fuel burn, the Cirrus Vision Jet SF50 and HondaJet Elite II land within a few percent of each other at roughly 4.4 nautical miles per gallon, despite very different engine layouts.
- The Piaggio Avanti EVO burns more fuel per mile than either jet, around 3.7 nmpg, but its twin-turboprop pusher design reaches cruise speeds up to 402 knots, faster than most light jets.
- The Avanti is technically a turboprop, not a jet, despite jet-like speed and cabin size, which matters for how it’s categorized and operated.
- The right choice depends on mission: the Cirrus and HondaJet suit shorter regional missions where per-mile fuel cost matters most, while the Avanti suits operators who need speed and won’t accept typical turboprop cruise limits.
Three aircraft come up again and again in searches for the most fuel-efficient private jet: the Cirrus Vision Jet SF50, the HondaJet Elite II, and the Piaggio Avanti EVO. Each takes a completely different engineering approach to efficiency, a single turbofan, twin over-wing turbofans, and twin pusher turboprops, and comparing their published fuel-burn figures directly can be misleading unless you account for how fast each one actually flies. This piece puts the three head-to-head using a consistent efficiency calculation, not just the headline gallons-per-hour number.
Three Different Approaches to Fuel Efficiency
Fuel burn per hour tells you how much an aircraft consumes while flying, but it doesn’t tell you how far that fuel takes you. A jet burning more fuel per hour but flying meaningfully faster can still deliver comparable or better fuel economy per mile flown. That’s exactly the dynamic across these three aircraft, and it’s why ranking them by raw gallons-per-hour alone produces a misleading picture.
Cirrus Vision Jet SF50
The Vision Jet is the only single-engine jet in production, burning approximately 70 gallons per hour at a 311-knot cruise speed. Its composite airframe and single Williams FJ33 turbofan keep both weight and fuel burn low, and it’s the only aircraft here built around a whole-airframe parachute system as a standard safety feature. For the full breakdown of the Vision Jet’s design and where it ranks against the rest of the light jet field, see our complete fuel-efficient private jets guide.
HondaJet Elite II (HA-420)
The Elite II burns roughly 96 gallons per hour at typical cruise, reaching a top cruise speed of 422 knots on twin GE Honda HF120 turbofans mounted above the wing rather than on the fuselage. That layout is unusual specifically because it reduces cabin noise and aerodynamic drag at the same time, a design trade-off most manufacturers don’t attempt. We cover the Elite II’s full specification set in the same fuel-efficient jets guide referenced above.
Piaggio Avanti EVO: The Turboprop That Flies Like a Jet
The Avanti EVO is the outlier here, and not just on fuel burn. It’s a twin-turboprop, not a jet, but its unusual three-surface layout, a forward canard, a mid-mounted main wing, and rear-facing pusher propellers driven by twin Pratt & Whitney Canada PT6A-66B engines, lets it cruise at speeds up to 402 knots, faster than most light jets and far faster than any conventional turboprop (Quantum Jets, 2026).
Fuel burn runs 90 to 129 gallons per hour depending on cruise power setting (GlobalAir, 2026), with a maximum range of 1,510 nautical miles on full fuel carrying four passengers, extendable to roughly 1,809 nm with the optional auxiliary tank. That combination, jet-competitive speed on turboprop fuel-burn economics, is the Avanti’s actual pitch: it isn’t the most efficient aircraft on this list per mile, but it’s the only one that gets genuinely close to jet cruise speeds without jet fuel burn.
Side-by-Side Comparison
| Aircraft | Type | Cruise Speed | Fuel Burn | Range |
|---|---|---|---|---|
| Cirrus Vision Jet SF50 | Single turbofan jet | 311 kt | ~70 GPH | 1,275 nm |
| HondaJet Elite II | Twin over-wing turbofan jet | 422 kt | ~96 GPH | 1,223 nm |
| Piaggio Avanti EVO | Twin pusher turboprop | up to 402 kt | 90-129 GPH | 1,510 nm |
What the Efficiency Numbers Actually Show
Dividing cruise speed by fuel burn gives a consistent nautical-miles-per-gallon figure for each aircraft, and it tells a different story than raw fuel burn alone. The Cirrus (311 kt / 70 GPH) works out to roughly 4.4 nmpg. The HondaJet (422 kt / 96 GPH) comes out almost identical, also around 4.4 nmpg, despite burning nearly 40% more fuel per hour, because it’s also flying more than 100 knots faster. The Avanti (402 kt / ~109 GPH) lands at roughly 3.7 nmpg, genuinely less efficient per mile than either jet, but still faster point-to-point than the Cirrus on a typical mission.
Which One Is Actually Right for You?
Mission profile settles this faster than any spec sheet. If per-mile fuel cost is the priority and missions are typically under 1,000 nautical miles, the Cirrus and HondaJet are essentially tied on true efficiency, so the decision comes down to cabin size and speed preference rather than fuel economy. The Cirrus seats up to seven and carries the lowest acquisition and operating cost of the three; the HondaJet trades some of that cost advantage for a meaningfully faster cruise and its distinctive over-wing engine layout.
If the mission profile needs jet-competitive cruise speed but the budget or mission favors turboprop operating economics, the Avanti’s speed advantage is hard to match in its class, even at a real per-mile fuel cost premium over the two jets. Operators running frequent longer-range missions, where the Avanti’s 1,510 nm range edges out both jets, tend to find that speed and range advantage outweighs the per-mile fuel cost gap.
Frequently Asked Questions
Is the HondaJet Elite II more fuel efficient than the Cirrus Vision Jet?
Not meaningfully. Calculated on a consistent nautical-miles-per-gallon basis, both aircraft land within a few percent of each other at roughly 4.4 nmpg, despite the HondaJet burning more fuel per hour, because it also flies faster.
Is the Piaggio Avanti a jet or a turboprop?
It’s a twin turboprop. It’s often mistaken for a jet because its three-surface design and pusher propellers let it cruise close to jet speeds, but it’s certified and operated as a turboprop.
What is the fuel burn of the Piaggio Avanti EVO?
Published figures range from about 90 to 129 gallons per hour depending on cruise power setting, with roughly 109 GPH as a typical midpoint figure.
Which is the most fuel-efficient private jet overall?
Among true jets, the Cirrus Vision Jet SF50 and HondaJet Elite II are essentially tied on per-mile efficiency. For the full ranked list across ten aircraft, see our complete fuel-efficient private jets guide.
Why does the Piaggio Avanti have a longer range than either jet despite burning more fuel?
Range depends on total usable fuel capacity, not just burn rate. The Avanti carries more fuel and, with its optional auxiliary tank, extends to roughly 1,809 nm, which is enough to outrange both the Cirrus and HondaJet even at a higher per-mile fuel cost.
Bottom Line
Raw fuel-burn figures rank the Cirrus Vision Jet ahead of the HondaJet Elite II, but once speed is factored in consistently, the two are close to tied on actual efficiency per mile flown. The Piaggio Avanti EVO trades some of that per-mile efficiency for cruise speeds neither light jet can match, which is a genuinely different value proposition, not a worse one. The right pick depends on whether your missions are decided by fuel cost or by how fast you need to get there.
