Bombardier Challenger 3500 vs Bombardier Challenger 650 vs Embraer Praetor 600 vs Gulfstream G280 vs Gulfstream G400

The Bombardier Challenger 3500, Embraer Praetor 600, and Gulfstream G280 are typically positioned in the super-midsize category, while the Bombardier Challenger 650 and Gulfstream G400 sit in the large-cabin segment. For range, the Challenger 3500 and Praetor 600 are broadly comparable super-midsize transcontinental jets at roughly the mid‑3,000‑nm class, whereas the G280 generally leads that group with around 3,600 nm capability. Stepping up, the Challenger 650 offers a longer large-cabin reach at about 4,000 nm. The Gulfstream G400 is the range standout here, designed for true intercontinental missions at roughly 4,200 nm. Passenger capacity follows cabin class more than range: the super-midsize trio (Challenger 3500, Praetor 600, G280) is commonly configured for about 8–10 passengers, with maximum layouts generally in the low to mid-teens. The large-cabin Challenger 650 typically seats around 10–12 in comfort, with higher maximums possible, while the G400 is generally planned around 12 passengers with higher-density options.
