The Aqua hatchback, known as the Prius C in international markets has recently been launched by Toyota in Japan.
Amazingly, the model has a fuel efficiency of 35.4 km/L (83.3 mpg US; 2.8L/ 100km). A combined motor and engine output of 100 PS (98 bhp / 73 kW), Aqua has a 1.5-litre Toyota Hybrid System II (THS II). Another characteristic of this model is a cooled Exhaust-Gas Recirculation system and a battery powered water pump. The water pump, unlike other traditional designs, reduces friction on the engine and allows precise control of coolant flow.
