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.

De-rated and increased thrust variants

A number of de-rated, Stage 4 noise compliant engines have been produced from the -A5 configuration, as well as two variants with significant increase in thrust, thus expanding the thrust range from 23,500 lbf to 33,000 lbf: * The thrust ''V2524-A5'' for the Airbus A319 * The thrust ''V2527-A5'' for the

* The thrust ''V2525-D5'' for the McDonnell Douglas MD-90-30. Engine accessories are mounted the side instead of bottom to accommodate lateral mounting. Also has an option in the cockpit to add 3,000 pounds (13 kN) additional thrust for "hot and high" conditions * The thrust ''V2533-A5'' for the

V2500SelectOne

On October 10, 2005, IAE announced the launch of the V2500Select—later called V2500SelectOne—with a sale to IndiGo Airlines to power 100 A320 series aircraft. The V2500SelectOne is a combination performance improvement package and aftermarket agreement. In February 2009, Pratt & Whitney upgraded the first V2500-A5 to the SelectOne Retrofit standard; the engine was owned by US Airways and had been in use since 1998.

V2500SelectTwo

On March 15, 2011, IAE announced an upgrade option of V2500 SelectOne Engines to the SelectTwo Program. It offers reduced fuel consumption due to a software-upgrade and Reduced Ground Idle (RGI), and is available since 2014 for the V2500-A5 variants.
