Toyota will unveil two more concepts called Aqua Cross and Aqua Air. The roadster study approaches the hybrid vehicle theme in a more entertaining way and may even preview as a future convertible hybrid model.

The concept measures 3,990mm long, 1,690mm wide and 1,440mm tall and has a wheelbase of 2,550mm. The study also features the same hybrid powertrain of the Aqua G Sports, consisting of a 1.5 liter Atkinson cycle petrol engine, an electric motor and a CVT transmission. The concept has a combined output of 100 horsepower and an average fuel economy of 35.4 km/liter in Japan (2.82 l/100 km/83.2 mpg US).
