The Acura MDX is a mid-size luxury crossover SUV with three-row seating produced by the Japanese automaker Honda under its luxury Acura division since 2000. The alphanumeric moniker stands for "Multi-Dimensional" luxury. It has ranked as the second-best selling mid-size luxury SUV after the Lexus RX. The MDX is the first luxury crossover SUV to have standard third-row seating, and shares its platform with the Honda Pilot. The Pilot was made available with an eight person seating configuration, while the MDX exclusively seats seven, with two seating positions in the third row. The MDX was introduced on October 5, 2000 as a 2001 model, replacing the slow-selling U.S.-only body-on-frame SLX, based on the Isuzu Trooper. In Japan, it was made to replace the Honda Horizon (also based on the Trooper) which was discontinued in 1999. In 2003, the vehicle went on sale in Japan and Australia as the Honda MDX; sales with Honda badges ended with the introduction of the second generation three years later.
