Bombardier’s Challenger series, perhaps its most successful line, has only become better with experience.Because the original Challenger was so successful, Bombardier continues to use its general design while incorporating up-to-date technology and improvements on well-received components. It would be a challenge, pun intended, to fill the shoes of the Challenger 604, the “best-selling model in the heavy-iron category.” However, the Challenger 605 maintains every praised feature of its predecessor, adding freedom, innovation and performance capabilities. It’s no wonder that this $27 million long-range business jet is a valuable asset to corporate clients.For good reason, Bombardier chose to preserve the spacious “Challenger” cabin that has accommodated business travelers for years. In a combination of club, divan and individual seating, the Challenger 605 typically carries 10-12 passengers.
