Despite the sharp growth in the adoption of the use of electric vehicles inthe world and notably in Brazil during the year 2023, many research gaps are stillpresent. Thus, this thesis proposes to investigate the factors that affect theintention of adoption of electric vehicles by consumers, proposing a new model,developed from the Unified Theory of Acceptance and Use of Technologies 2 –UTAUT 2, which integrates social, environmental, economic, emotional andcognitive aspects. This study, also sought to evaluate the impact of twomoderating variables, specifically age and gender, on the intention to adoptelectric vehicles. An exploratory quantitative phase was conducted through asurvey applied to 715 respondents over 18 years of age, of both genders. Of theconstructs used in the initial model, personal innovation, price sensitivity,government incentives, and hedonic motivation were relevant. On the other hand,social influence was of low importance in the consumer s decision-makingprocess. There was no change in relevance among the constructs in the alternativemodel. Among the two models studied, it can be stated that the initial model wasmore significant in representing the aspects that form the intention to adopt thesevehicles. From the sample space (N=660), in the sample of the Baby Boomersgeneration (n=155), it was possible to see that the constructs personal innovationand hedonic motivation are more decisive for the adoption of these vehicles. Forgeneration X (n=161), price sensitivity was relevant, in addition to personalinnovation. Generation Y (n=179) was characterized by the appeal of pricesensitivity and performance expectations. Generation Z (n=165) valued hedonicmotivation and government incentives. For females (N=321), hedonic motivationand personal innovation were decisive, while for males (n=339), price andperformance were important.
