Phenom 300E vs Citation CJ4 Gen2 for Light Jet Buyers
Compare the Phenom 300E and Citation CJ4 Gen2 on range, speed, cabin space, payload, runway performance, operating costs and the 2026 market.
Two of the Most Capable Single-Pilot Light Jets
The Embraer Phenom 300E and Cessna Citation CJ4 Gen2 compete for buyers who want serious business-aircraft capability without moving into a larger midsize jet.
Both can be flown by a single qualified pilot. Both cruise above 450 knots. Both reach 45,000 feet. Both offer enough range for substantial US domestic missions and many European sectors.
The differences become more useful when the aircraft are examined with passengers and baggage onboard. The Phenom 300E gives buyers more cabin width, considerably more full-fuel payload and higher maximum cruise speed. The CJ4 Gen2 counters with a longer manufacturer-published ferry range, a slightly longer cabin and the depth of the Citation operating ecosystem.
ACMI World's guide to planning executive travel already identifies the Phenom 300 and Citation CJ4 as relevant aircraft for smaller executive groups. Buyers should approach the comparison the same way: match the aircraft to the mission rather than selecting on category alone.
The Short Answer
The Phenom 300E is the stronger performance proposition when the aircraft is carrying people. It is faster, wider, has more cabin volume and provides substantially more payload with maximum fuel.
The CJ4 Gen2 remains compelling for buyers who value Citation commonality, a slightly longer passenger cabin, a mature US support network and the economics of the CJ platform. For new-aircraft buyers in 2026, however, both product lines are already evolving toward the Phenom 300EV and Citation CJ4 Gen3.

The Brochure Range Figures Need Context
Textron Aviation publishes a maximum range of 2,165 nautical miles for the CJ4 Gen2. That figure is based on a ferry mission at long-range cruise with NBAA IFR reserves.
Embraer publishes 2,010 nautical miles for the Phenom 300E with five occupants weighing 200 pounds each, long-range cruise and NBAA IFR reserves.
Those numbers should not be compared as though they were generated using identical payload assumptions. Once the aircraft are compared using equivalent passenger loads, the result changes.
AvBuyer's 2026 analysis placed the Phenom 300E at 2,010 nautical miles with four passengers and available fuel, while all three light jets included in its study were within roughly 100 nautical miles of one another. An earlier direct CJ4 Gen2 comparison calculated approximately 1,927 nautical miles for the Citation using the same four-passenger methodology.
Buyer Takeaway
Do not conclude that the CJ4 automatically flies farther because its manufacturer page shows 2,165 nm. For missions with passengers onboard, compare both aircraft using the same payload, reserve and wind assumptions.
Full-Fuel Payload Strongly Favors the Phenom 300E
The payload difference is more significant than the range difference.
Embraer publishes a maximum payload of 2,636 pounds for the Phenom 300E. Textron Aviation lists 2,200 pounds for the CJ4 Gen2.
More importantly, AvBuyer calculates approximately 1,586 pounds of available payload with maximum fuel for the Phenom 300E. Textron's current CJ4 Gen2 data lists approximately 1,102 pounds of full-fuel payload.
That difference is almost 500 pounds. In practical terms, it can represent two passengers and baggage, or allow the operator to retain more fuel while carrying the same executive team.

The Phenom Is Wider While the CJ4 Is Slightly Longer
The Phenom 300E has the more generous cross-section. Independent comparison data places cabin width at approximately 5.1 feet compared with about 4.83 feet in the CJ4 Gen2.
Cabin height is approximately 4.9 feet in the Phenom and 4.75 feet in the Citation. Neither is a stand-up midsize cabin, but the extra width and height become noticeable when passengers spend three or four hours onboard.
The CJ4 Gen2 is fractionally longer inside. Textron lists a cabin length of 17 feet 4 inches, compared with approximately 17.2 feet for the Phenom in AvBuyer's comparison.
The Phenom still produces more total main passenger cabin volume, at approximately 324 cubic feet versus 293 cubic feet for the Citation.
Where the Phenom 300E Wins
Cabin width, cabin height and overall passenger volume all favor the Embraer. For buyers who routinely fill the cabin, those dimensions may matter more than the Citation's additional inch or two of longitudinal space.
The Phenom Also Carries More Baggage Volume
Embraer's current Phenom 300E brochure lists 84 cubic feet of total baggage and stowage volume.
Textron Aviation publishes 77.1 cubic feet for the CJ4 Gen2.
AvBuyer breaks the compartments down further, listing approximately 10 cubic feet internally and 74 externally for the Phenom compared with roughly 7 cubic feet internally and 71 externally for the Citation. For frequent golf, ski or multi-day business travel, the difference is worth testing with representative luggage rather than relying only on passenger-seat capacity.
The Phenom Has the Performance Edge
Embraer publishes a high-speed cruise of 464 knots and a maximum operating speed of Mach 0.80. Textron publishes 451 knots and Mach 0.77 for the CJ4 Gen2.
A 13-knot difference is not transformational on short sectors, but across high annual utilization it contributes to the Phenom's broader combination of speed, payload and loaded range.
Phenom 300E Takeoff Performance Is Better on Paper
Embraer publishes a 3,209-foot takeoff distance for the Phenom 300E at maximum takeoff weight, sea level and ISA conditions.
Textron Aviation publishes 3,410 feet for the Citation CJ4 Gen2 under its standard headline conditions.
That gives the Phenom an advantage of about 200 feet in the manufacturer data. Real operations should still be modeled for runway elevation, temperature, runway condition, obstacles, payload and fuel because a brochure figure does not guarantee useful range from every short airport.
Buyers focused heavily on airport access should also read ACMI World's guide to the best jets for short runways , which includes the CJ4 Gen2 among the practical light-jet choices.
Both Aircraft Are Built Around Single-Pilot Capability
Single-pilot certification is commercially important in this segment because many buyers are owner-pilots or operate small corporate flight departments.
The Phenom 300E uses Embraer's Prodigy Touch flight deck based on the Garmin G3000. It incorporates features such as Runway Overrun Awareness and Alerting System, Emergency Descent Mode and available autothrottle.
The CJ4 Gen2 uses the established Collins Pro Line 21 flight deck. For pilots already operating CJ-series aircraft, the Citation family and common type-rating environment can have significant training and fleet-management value.
This is also where the comparison is changing rapidly. Both manufacturers are moving their light jets toward significantly more automation.
2026 Buyer Update
New-Aircraft Buyers Should Also Look at the Phenom 300EV and CJ4 Gen3
Embraer launched the Phenom 300EV in July 2026, and the aircraft received FAA, EASA and ANAC certification in August. The new version adds Garmin Emergency Autoland and raises published range to 2,055 nautical miles while retaining speeds up to Mach 0.80.
Textron is simultaneously preparing the Citation CJ4 Gen3, which introduces Garmin G3000 PRIME avionics, autothrottle and Garmin Emergency Autoland. Textron still described the CJ4 Gen3 as upcoming when it delivered the 500th CJ4-series aircraft in August 2026.
Operating Cost Is Too Close to Decide the Purchase Alone
Operating cost estimates change with fuel price, maintenance enrollment, crew structure, utilization and the methodology used by the data provider.
AvBuyer's May 2026 comparison estimated the Phenom 300E at roughly 158 gallons of fuel per hour and the Citation CJ4 Gen2 at approximately 172 gallons per hour.
In that analysis the Phenom had the lowest estimated hourly variable cost among the three light jets studied, while the CJ4 Gen2 produced the lowest estimated cost per nautical mile.
That apparent contradiction is useful. A jet can consume less per hour while another produces a lower modeled cost per mile depending on speed, maintenance assumptions and mission profile. Buyers should therefore model annual trips rather than selecting an aircraft from one published hourly figure.
Both Aircraft Sit in Highly Established Families
Embraer has built substantial market depth around the Phenom 300 family. The manufacturer says the platform has been the world's best-selling light jet for 14 consecutive years.
Textron Aviation reached the 500th delivery of the CJ4 series in August 2026. The milestone aircraft was a CJ4 Gen2, demonstrating how mature the Citation platform has become.
AvBuyer's May 2026 market data showed the Phenom 300E averaging 7.5 new and used transactions per month over the preceding year, the highest transaction rate among the aircraft in its comparison.
For buyers concerned about eventual resale, both aircraft benefit from recognized global brands and substantial installed fleets. Individual residual value will still depend on age, total time, maintenance programs, inspection status, avionics and market supply when the aircraft is sold.

Phenom 300E or Citation CJ4 Gen2?
On the numbers that matter most with passengers onboard, the Phenom 300E has the stronger overall performance package. It is faster, wider, carries more payload with maximum fuel, offers more baggage volume and requires less runway under the manufacturers' published baseline figures.
The Citation CJ4 Gen2 remains an extremely credible aircraft. Its strengths lie in the Citation platform itself: fleet maturity, owner-operator familiarity, a substantial support network and a cabin that is marginally longer than the Embraer's.
For a buyer entering either family without an existing fleet preference, the Phenom 300E provides the more compelling combination of payload, cabin cross-section and performance. For an existing Citation operator, the economic value of commonality can narrow that advantage considerably.
