G280 vs G450
The G450 leads, topping 3 of 7 compared metrics.
The Gulfstream Aerospace G280 (introduced 2012) and the Gulfstream Aerospace G450 (introduced 2005) are two aircraft buyers regularly weigh against each other. Both are business jets, which makes them natural cross-shopping rivals. The clearest separation between them is cabin capacity, where the G450 carries more passengers. undefined

G280 vs G450: the key differences
- The G450 delivers 21% more range (G280: 3,600 nm; G450: 4,350 nm).
- The G280 and G450 are evenly matched on cruise speed, both at 459 kt.
- The G450 delivers 60% more passenger capacity (G280: 10 seats; G450: 16 seats).
- The G280 is the newer design (introduced 2012 versus 2005 for the G450), a gap of 7 years that usually shows up in avionics, cabin systems and fuel burn.
- The G450 is the larger aircraft by maximum takeoff weight (74,600 lbs versus 39,600 lbs), which typically buys more cabin and payload at the cost of higher trip economics.
Which mission suits which aircraft
Both aircraft are built for long-haul and transatlantic missions, so outright range rarely separates them — the call leans on cabin (the G450 seats more), trip economics and what is actually available on the market. Match the airframe to how you fly most weeks, not to the headline range figure.
Which should you choose?
On published specifications the G450 leads on both range and cabin capacity, so it suits operators who want maximum mission flexibility from a single airframe. The G280 can still be the smarter buy on acquisition cost, operating economics, runway performance, or current availability — the factors that rarely show up in a spec sheet. Our acquisition advisory team can model both against your actual mission profile before you commit.
