The A320 series has two variants, the A320-100 and A320-200. Only 21 A320-100s were produced;^[39] these aircraft, the first to be manufactured, were only delivered to Air Inter (later acquired by Air France) and British Airways (as a result of an order from British Caledonian Airways made prior to its acquisition by British Airways). Compared to the A320-100, the primary changes on A320-200 are wingtip fences and increased fuel capacity for increased range. Indian Airlines used its first 31 A320-200s with double-bogie main landing gear for airfields with poor runway condition which a single-bogie main gear could not manage. Typical range with 150 passengers for the A320-200 is about 3,300 nmi (6,150 km). It is powered by two CFMI CFM56-5s or IAE V2500s with thrust ratings between 113 to 120 kN (25,400 to 27,000 lbf). The lowest speed an A320 can fly is approximately207 km/h.^[119]
