Toyota Sweden has created a free iPhone app which aims to help drivers to reduce their CO2 emissions by as much as 10% over a journey.
The ingenious application shows a virtual glass of water on the iPhone screen. The water in the glass reacts to sudden acceleration or braking. A smooth drive ensures that no water is spilt. The amount of water that splashes out of the glass is recorded so the driver can assess their performance at the end of the trip.
The goal of the application is to provide drivers with a pleasurable, yet challenging way to reduce fuel consumption and CO2 emissions. Known as A Glass of Water, the app can be downloaded from the Toyota Sweden website or the iTunes store.
