This paper reports and compares the performance of five motorcycles, four of them powered by Internal Combustion Engine (ICE) and one by an Electric Engine (EE). The power grade of those vehicles represents more than 80% of Brazilian motorcycle fleet. Motorcycles are submitted to standard routines, in accordance with regulations established by PROMOT (Control of Air Pollution for Motorcycles and Similar Vehicles). Main output parameters allowed for the assessment of their energy performance in respect to the energy source, followed by their greenhouse gases emission potential due to CO2, CH4 and N2O. The paper presents regulated emissions results for CO, THC and NOx, provided by EE and ICE engines. Different ICE motorcycles are tested, and fueled by a range of ethanol/gasoline contents from 22 to 100%, allowing to analyze the influence of the renewable biofuel on the motorcycle energetic efficiency and emissions.
