Challenger 300 vs G150
The Challenger 300 leads, topping 4 of 7 compared metrics.
The Bombardier Aviation Challenger 300 (introduced 2004) and the Gulfstream Aerospace G150 (introduced 2006) 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 Challenger 300 carries more passengers. Below we compare them spec by spec, then break down which aircraft suits which mission.

Challenger 300 vs G150: the key differences
- The Challenger 300 delivers 4% more range (Challenger 300: 3,065 nm; G150: 2,950 nm).
- The Challenger 300 and G150 are evenly matched on cruise speed, both at 459 kt.
- The Challenger 300 delivers 13% more passenger capacity (Challenger 300: 9 seats; G150: 8 seats).
- The G150 is the newer design (introduced 2006 versus 2004 for the Challenger 300), a gap of 2 years that usually shows up in avionics, cabin systems and fuel burn.
- The Challenger 300 is the larger aircraft by maximum takeoff weight (38,850 lbs versus 26,100 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 transcontinental missions, so outright range rarely separates them — the call leans on cabin (the Challenger 300 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 Challenger 300 leads on both range and cabin capacity, so it suits operators who want maximum mission flexibility from a single airframe. The G150 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.
