The Mitsubishi ASX (abbreviation of "Active Sports Crossover") is a subcompact crossover SUV manufactured by the Japanese automaker Mitsubishi Motors. On introduction, it was positioned below the Outlander in Mitsubishi's crossover SUV line-up, until the Eclipse Cross filled the gap between the ASX and Outlander in 2017. It was built on the GS platform closely shared with the Lancer and Outlander.
