In practice, this places the Model 60 in a similar long-term evolution path as Boeing 737 (Original → Classic → NG → MAX) and Airbus A320 (A320 → A321 stretch family) Second Generation — CFM56-3(737-300 / Early A320 Class)Engine UpgradeCFM56-3 (~90 kN)Key benefits of significantly improved fuel efficiency, lower engine noise, higher MTOW capability, extended range than its predecessor. Third Generation — IAE V2500(A320 Market Response)Engine OptionIAE V2500 (~100–110 kN)Key benefits of lower fuel burn per seat, improved hot-and-high performance, longer operational range, higher MTOW margin CG & Nacelle Placement Adjustments from Original lengthTo balance heavier modern engines, the engines moved slightly forward, nacelles mounted higherCG corrected via fuselage plugs:+2 m aft+1 m forward Resulting Aircraft Length ≈ 37.5 m. This becomes a direct competitor to the Boeing 737-300, while retaining the 5-abreast comfort with high-speed Convair wing characteristicsAdditional fuselage stretch+2 m forward plug+1 m forward plugResulting Aircraft Length ≈ 40.5
