Challenger 605 vs Challenger 650
The Challenger 605 leads, topping 1 of 7 compared metrics.
Cross-shopping the Bombardier Aviation Challenger 605 (introduced 2006) against the Bombardier Aviation Challenger 650 (introduced 2015) is a common decision, and the two sit closer on paper than the badges suggest. Both are business jets, which makes them natural cross-shopping rivals. On paper they are closely matched, so the decision usually turns on cabin, economics and availability.

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 Challenger 650 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.
