Challenger 605 vs G280
The G280 leads, topping 4 of 7 compared metrics.
Put the Bombardier Aviation Challenger 605 (introduced 2006) beside the Gulfstream Aerospace G280 (introduced 2012) and the trade-offs sharpen fast. Both are business jets, which makes them natural cross-shopping rivals. The clearest separation between them is cabin capacity, where the Challenger 605 carries more passengers. Below we compare them spec by spec, then break down which aircraft suits which mission.

Challenger 605 vs G280: the key differences
- The Challenger 605 delivers 11% more range (Challenger 605: 4,000 nm; G280: 3,600 nm).
- The Challenger 605 and G280 are evenly matched on cruise speed, both at 459 kt.
- The Challenger 605 delivers 20% more passenger capacity (Challenger 605: 12 seats; G280: 10 seats).
- The G280 is the newer design (introduced 2012 versus 2006 for the Challenger 605), a gap of 6 years that usually shows up in avionics, cabin systems and fuel burn.
- The Challenger 605 is the larger aircraft by maximum takeoff weight (48,300 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 Challenger 605 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 605 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.
