The European automotive market is undergoing a profound technological and regulatory transformation, marked by accelerating electrification, ambitious climate policies, and evolving consumer attitudes. Rather than focusing primarily on forecasting vehicle sales, this thesis aims to identify and quantify the key drivers behind the shift from internal combustion engine (ICE) vehicles to electric powertrains across European Union member states. The analysis will examine how regulatory frameworks, government incentives, macroeconomic conditions, fuel and electricity prices, charging infrastructure, and consumer perception jointly influence the adoption of electric vehicles. To assess the relative weight of these factors, the research will employ a linear regression model using a panel dataset constructed at the country–year level.
