The purpose of this report is to evaluate the fuel efficiency of selected alternative fuels based on vehicle performance in a standardised drive cycle test. All studies reviewed are either based on computer modelling of current or future vehicles or tests of just one alternative fuel, under different conditions and concentrations against either petrol or diesel. No studies were found testing more than one type of alternative fuel in the same setup. Do to this one should be careful when comparing results on several alternative fuels. Only few studies have been focused on vehicle energy efficiency. This screening indicates methanol, methanol-ethanol blends and CNG to be readily availability, economic feasible and with the introduction of the DISI engine not technologically challenging compared to traditional fuels. Studies across fuel types indicate a marginally better fuel utilization for methanol-ethanol fuel mixes.
