This analysis from the Northeast States for Coordinated Air Use Management (NESCAUM) compared the 2018 advertising expenditures in local markets in California and the Northeast for the best-selling electric vehicle (EV) model and the bestselling conventional vehicle model from six of the top EV manufacturers, including: Fiat-Chrysler, Ford, General Motors, Honda, Nissan, and Toyota. For EV models where 2017 data was available, the report also compared advertising expenditures in 2018 to 2017. Data for the report was purchased from InterQ Research and compiled by Kantar Media. It includes estimated expenditures for TV, radio, print, and online advertising and covers money spent on advertising for select models, regardless of source of the spending. The report found that when aggregating the 2018 ad expenditure data, industry spending on ads for EVs was less than 10% of what automakers spent advertising best-selling conventional vehicles.
