The Mitsubishi Outlander is a mid-size crossover manufactured by Japanese automaker Mitsubishi. It was originally known as the Mitsubishi Airtrek when it was introduced in Japan in 2001, and was based on the Mitsubishi ASX concept vehicle exhibited at the 2001 North American International Auto Show. It was sold at Mitsubishi Japan dealership chain called Car Plaza. The ASX (Active Sports Crossover) represented Mitsubishi's approach to the industry wide SUV trend for retaining the all-season and off-road abilities offered by a high ground clearance and four-wheel drive, while still offering car-like levels of emissions, economy and size.
