A hybrid electric vehicle manufactured by Honda and the first production vehicle to feature Honda's Integrated Motor Assist system. The first-generation Insight was produced from 1999 to 2006 as a three-door hatchback.

Honda introduced the second-generation Insight to its home market of Japan in February 2009. The car went on sale in the United States on March 24, 2009. At $19,800 as a five-door hatchback it is the least expensive hybrid available in the US. In December 2010, Honda introduced a less expensive base model for the 2011 model year priced US$18,200. The Insight was launched April 2009 in the UK as the most affordable hybrid on the market with a starting price from £15,490, which was more than £2,000 lower than other hybrids, and became the best selling hybrid for the month.

Honda's Insight, billed as the cheapest gas-electric hybrid on the market, ranked as the top-selling vehicle in Japan for the month of April 2009, the first time a hybrid has clinched that spot. During its first twelve months after first available in the Japanese market, the second-generation Insight sold 143,015 units around the world.
