There is a price threshold at which electric vehicles begin to make financial sense for a given consumer — a level at which the fuel savings from going electric, combined with available used EV pricing, produce a total cost of ownership calculation that favors the electric option. That threshold is different for every consumer, depending on mileage, current vehicle fuel efficiency, local gas prices, and available EV options. But at $3.90 per gallon, US interest in electric vehicles is surging precisely because millions more Americans have now crossed their personal threshold than were above it just a month ago.
The price that crossed those thresholds was created by Iran’s closure of the Strait of Hormuz following US and Israeli military operations. That waterway carries roughly one-fifth of global oil supply, and its disruption elevated crude prices and pushed American retail fuel costs to their current elevated level. CarEdge documented the resulting behavioral shift: a 20 percent EV search increase as consumers respond to financial calculations that now favor electric transportation in ways they previously did not.
The personal threshold concept explains why gas price spikes are such powerful EV motivators. At $3.00 gas, many consumers’ personal math does not yet favor an EV switch. At $3.50, some cross their threshold. At $3.90, many more do — particularly when combined with used EV pricing that has come down to sub-$25,000 levels. Edmunds’ Jessica Caldwell noted that the combination of rising gas prices and falling used EV prices has been moving more consumers above their personal thresholds for the past several years, and the current conflict has accelerated that movement dramatically.
CarEdge’s Justin Fischer said the 20 percent search increase likely understates the full extent of threshold crossing — many consumers who have crossed their mathematical threshold are doing mental calculations before turning to formal online research. The search activity is the visible manifestation of a broader internal recalculation process happening simultaneously across millions of American households.
The threshold concept also helps explain why the current moment may be more commercially significant than previous gas price spikes. The used EV market at sub-$25,000 has lowered thresholds considerably — consumers who would not have crossed their threshold at $3.90 gas without a $25,000 used EV available may be crossing it now. The combination of elevated prices and improved affordability has expanded the universe of Americans above their personal EV threshold to a level never previously seen in this market.
