Toyota Aqua

The Toyota Aqua is a full hybrid electric subcompact/supermini hatchback (B-segment) manufactured and marketed by Toyota since 2011. The nameplate is exclusive to the Japanese domestic market, as the vehicle was exported to overseas markets as the Prius c, leveraging the popularity of the Prius hybrid car nameplate and marketed as the smaller alternative to the Prius liftback.

The Aqua is considered the most successful nameplate launch in Japan in the last 20 years. As of January 2017, the Aqua/Prius c is the second highest-selling Toyota hybrid model after the regular Prius, with 1,380,100 units sold worldwide. Japan as Aqua's market leader has sold 1,154,500 units of the model through January 2017. The Aqua was the best-selling (non-kei) car in Japan for three years in a row, from 2013 to 2015.

The name Aqua means 'water' in Latin. The name was meant to associate the car with an "image of clean transparency" and "something that is universally cherished".
