E-mobility has been a buzz word since few years and 100% across the entire auto industry is thrilling the automakers and consumers because of the unveiling uncertainties day by day. Dreams when realized face difficulties and this dream is sure to shake the entire Indian economy because of its footprints in the entire economic model. The below case throws light on the ill-effects of air pollution and how e-mobility can honestly fit into the shoes of an efficient emission reducer. The case also brings up the challenges that the Government is embedded upon and tries to assess the consumer behavior from different perspectives to accept this transition. The phase out of a technology that powered the vehicles for several decades is not easy and replacing the conventional internal combustion engines with battery powered alternative requires complete restructuring of the automotive framework within Indiaand is a great challenge moving forward.

Alternative fuel has become very significant and has an important role to play for both spark ignition and compression ignition engines, so the need to trim down dependency on gasoline as a fuel and its economic aspects has emerged as the reason of prime importance. Ethanol is one of the cost effective alternative fuel used to improve the performance of the engine. Various investigations carried out by the researchers, primarily focused on using alternative fuel to see the diminishing effect on the fuel consumption. The aim of the study is to analyze the performance of the engine by adding the ethanol with gasoline at certain percentages as ethanol-gasoline blend. The study is carried out in the existing SI engines by diagnosing various aspects such as air-fuel ratio, operating cylinder pressure ignition timing and compression ratio related to the performance parameters. Finally the performance of gasoline-ethanol blends (E10, E20, E25) are compared and analyzed with the gasoline. From the analysis it is noticed that the ethanol blends outperforms if the engine is modified as per the requirements.
