The CJ2+ is the improved version of the CJ2, offering lower fuel burn, longer range, and a larger cabin. Travelers like the idea of a private jet that performs economically without sacrificing performance or reliability. The CJ2+ increases performance and economy by using some of the most economic engines available, two Williams/Rolls-Royce FJ44-3A-24 turbofan engines, each of which delivers 2,400 lbs of thrust on takeoff. One of the best of his class.
