Platform Heritage

The Mitsubishi Outlander (Japanese: 三菱・アウトランダー, Hepburn: Mitsubishi Autorandā) is a compact crossover SUV manufactured by Japanese automaker Mitsubishi Motors since 2001. It was originally known as the Mitsubishi Airtrek (Japanese: 三菱・エアトレック, Hepburn: Mitsubishi Eatorekku) when it was introduced in Japan. The original Airtrek name was chosen to "describe the vehicle's ability to transport its passengers on adventure-packed journeys in a 'free-as-a-bird' manner", and was "coined from Air and Trek to express the idea of footloose, adventure-filled motoring pleasure." The Outlander nameplate which replaced it evoked a "feeling of journeying to distant, unexplored lands in search of adventure." The second generation of the vehicle was introduced in 2006 and all markets including Japan adopted the Outlander name, although production of the older version continued in parallel. It was built on the company's GS platform, and used various engines developed by Mitsubishi, Volkswagen, and PSA Peugeot Citroën. PSA's Citroën C-Crosser and Peugeot 4007, which were manufactured by Mitsubishi in Japan, are badge engineered versions of the second generation Outlander. Global sales achieved the 1.5 million unit milestone in October 2016, 15 years after its market launch. As part of the third generation line-up, Mitsubishi launched in January 2013 a plug-in hybrid model called Outlander PHEV. As of January 2022, global sales totaled about 300,000 units. The fourth-generation model was released in 2021 as a 2022 model. Following Mitsubishi's entry to Renault–Nissan–Mitsubishi Alliance, the fourth-generation Outlander is based on the Rogue/X-Trail, which is built on the CMF-CD platform.

  4. Run a MotoMetrics on-site scan for Mitsubishi Outlander before signing the bill of sale.

Vehicle health varies wildly by individual history. Aggregate recall and complaint data cannot tell you whether the specific car on the lot had its monitors cleared or its odometer rolled back. Verify the physical or digital scan before you sign a bill of sale.
