The 4,000th V2500 was delivered in August 2009 to the Brazilian flag carrier TAM and installed on the 4,000th Airbus A320 family aircraft, an A319. In early 2012, the 5,000th V2500 engine was delivered to SilkAir, and IAE achieved 100 million flying hours. Six years later, in June 2018, over 7,600 engines were delivered and the V2500 achieved 200 million flight hours on 3,100 aircraft in service.

A fourth booster stage was introduced into the engine basic configuration to increase core flow. This, together with a minor fan diameter and airflow increase, helped to increase the maximum thrust to 33,000 lbf (147 kN) thrust, to meet the requirements of the larger Airbus A321.
