Why can Saab BioPower cars use 100% bioethanol (E100) instead of E85?
E85 is the common blend for Europe and USA because of the requirements for good start- up in cold conditions. In Brazil, where a cold engine start is not an issue, E100 fuel has been used for many years. No matter what mix of bioethanol the 9-5 BioPower cars uses , it will add less ‘new’ CO2 to the atmosphere compared to a normal petrol engine. Saab is researching solutions to the cold start requirements with the goal of enabling BioPower cars to run on E100 on any market, regardless of climate conditions.
