What New in Transportation Energy
Towards the end of 2025, news coverage began to focus on affordability, and the price of new vehicles became a central proof point in articles of concern. The Transportation Energy Institute recognizes that affordability is a primary factor that should drive strategic development for the transportation sector, because if the consumer cannot afford or refuses to pay for a new market option, that option will fail. The news coverage was not wrong – and when we look at the data, there appears to be significant cause for concern.
