Ethanol | Vehicles went through chassis dynamometer testing as part of the study. The dynamometer simulated different road and vehicle operating conditions, helping researchers determine that e85 was the most efficient and cost-effective fuel tested.

Ethanol | Vehicles, like this sedan, went through chassis dynamometer testing as part of the study. The dynamometer simulated different road and vehicle operating conditions, allowing researchers to fully measure a number of important data points to measure the performance of different ethanol blends.

Ethanol | As shown in this chart from the study, as the ethanol content of the fuel increased from e10 to e20, e30 and e85, the energy conversion within the engine increased as well — meaning you could travel further using less energy. This was true for the three different flex fuel vehicles tested at different loads.
