A321-100
The original derivative of the A321, the A321-100, had shorter range than the A320 because no extra fuel tank was added to compensate for the increased weight. The MTOW of the A321-100 is 83,000 kg (183,000 lb). The A321-100 entered service with Lufthansain 1994. Only about 90 were produced; a few were later converted to the A321-200 variant.
A321-200
Airbus began development of the heavier and longer-range A321-200 in 1995 to give the A321 full-passenger transcontinental US range. This was achieved through higher thrust engines (V2533-A5 or CFM56-5B3), minor structural strengthening, and an increase in fuel capacity with the installation of one or two optional 2,990 L (790 US gal) tanks in the rear underfloor hold. The additional fuel tanks increased the total capacity to 30,030 L (7,930 US gal). These modifications also increased the max...
