Better fuel economy than expected
A detailed assessment of the technical performance of 93 FFVs (11 different models used in a variety of situations at all sites) revealed 1–26% higher energy effi ciency when running on E85, which resulted in better fuel economy than expected. In the best case only 1.14 times more E85 than petrol was necessary (instead of the theoretically assumed 1.41). This represents a signifi cant fi nding and is an important area for future research.
