Toyota has already brought us many hybrid variants of the Toyota Prius, available at Mark Miller Toyota Downtown in Salt Lake City, Utah; but they are only starting with electric. They want to be remembered for more advancements in fuel consumption.

The auto maker is looking into a better ethanol. New yeast being developed that will more efficiently ferments xylose, sugar produced when plant fibers break down, basically creating a super fuel.

This newly developed yeast produces the highest ethanol fermentation level known to human kind, and is capable of improving bio-fuel quality while also reducing production costs. Plans to perfect this ethanol, along with making ethanol a widely available commodity, are set to be completed by 2020.

The Toyota Biotechnology and Afforestation Laboratory is also developing a "cool-spot creation technology" for simulating the cooling effects of shade created by trees to be used in cars.¹
