[4] Mass production commenced on April 23 at Honda's assembly facility in Greensburg, Indiana[5] and U.S. sales began on May 22.

[6] Compared to the Civic, the ILX uses Acura's "Amplitude Reactive" dampers and a larger more rigid steering shaft for improved handling and ride quality characteristics.

It now came exclusively with an "Earth Dreams" direct injected 2.4-liter four-cylinder DOHC i-VTEC engine mated to an 8-speed dual-clutch transmission, a very closely related powertrain to that of the TLX, first introduced in 2014 (as a 2015 model).

[11] In September 2018, Acura revealed a second facelift for the ILX, incorporating what the company markets as its "Diamond Pentagon" grille.

In the interior, the overall design has revised seats, with the availability of red leather (only on the A-Spec), and an updated infotainment system — the latter 30% faster.

[12] Honda has offered several different four-cylinder gasoline engines in this model, similar to those in the CSX, TSX, and Civic Si.

[17] The ILX was discontinued after the 2022 model year, with the eleventh-generation Honda Civic-based Integra liftback replaced it as the brand's entry-level offering.
