Saab plans to unveil a 100 percent bioethanol-powered engine in Geneva next month.

According to a news release:

GM Powertrain CEO Kjell ac Bergstrom said: ‘Bioethanol is a potent, high-quality fuel which opens up exciting possibilities in helping to meet the environmental challenges that face us. As the need to reduce energy consumption increases, we are exploring ways to run smaller engines that give relatively high power, with and without hybrid technology. This concept car shows that bioethanol can play a key role in this “right-sizing” process, while also minimizing fossil fuel emissions.’
