This paper describes a study an influence of ethanol concentration in premium-ethanol fuel blends on vehicle performance and exhaust gas emissions.The study is based on the vehicle test on chassis dynamometer.Exhaust gas emission was measured on Rangemaster Classic Delux CDL110DFFCR/C 110cm Dual Fuel Range Cooker - Cream idle condition and using ECE standard regulation No.83-04.

Three compositions were performed on the first step, which are 3%, 10% and 20% of volume.Performance and emission results were compared to the test results on the same vehicle fuelled with 100% premium and pertamax.The test Cord results have shown that increasing concentration of ethanol will increase torque and power, reduce CO and HC emission, except on idle condition.10% ethanol concentration have identical performance characteristic with the same vehicle fuelled with pertamax, with 60% less CO emission on idle condition and 30% less when using ECE 83-04 standard.
