The massive tax and spending cut bill that Congress passed Thursday ends federal tax incentives for electric vehicles.

Buyers have until Sept. 30 to qualify for the federal tax credits on EVs before they are terminated. But experts say there are still strong financial reasons to consider buying the vehicles even without those incentives.

Before the bill passed, new electric vehicles came with a $7,500 federal tax credit, and used EVs included up to $4,000. Those incentives were originally designed to help make the vehicles more affordable. According to the latest data from Kelley Blue Book, the average purchase price of a new EV is roughly $9,000 higher in the United States than the average new gas-powered car. Used EVs on average cost $2,000 more than comparable gas cars.

Those credits, paired with other incentives in many states, helped bridge that price gap. Without them, Senior Policy Director Ingrid Malmgren of the nonprofit advocacy group Plug In America said they will become unaffordable to many lower- and middle-income Americans.

"That's really disappointing because ... they're just a really great way to reduce transportation energy cost burden," Malmgren said.

The up-front cost of an electric vehicle might be higher, but for those who can afford to consider the lifetime fuel and maintenance savings, Malmgren said the EV is still a good financial and environmental move in every state.

That is because electric vehicles might not be cheaper to buy, but they are cheaper to drive. Malmgren said that even without the federal tax credits, an electric vehicle owner would still come out ahead.

"Quickly you'll end up paying less than a gas car because it costs much less to fuel, and it needs almost nothing for maintenance," Malmgren said.

Malmgren said the point at which an EV driver's savings on fuel and maintenance outweigh the higher initial price varies. It depends on the kind of car and how often they are driven, as well as the cost of gasoline and electricity in an area. She said EV owners pay less in upkeep because the cars typically have fewer moving parts to maintain and require less frequent servicing. There are multiplecalculators online that pinpoint that moment based on some of those criteria.

A 2020 study in the academic journal Joule found that the average EV in the U.S. charged with a typical mix of public and private chargers saves the driver $7,700 in fuel costs over a 15-year life span, compared to filling a car with gas. Savings vary by state. The study found that someone charging a car at home during off-peak hours, deemed as a best-case scenario, could save more than $14,000 over 15 years in Washington, where electricity is relatively affordable. The study said that an EV driver in any state exhibiting typical driving and charging behavior would save money on fuel costs. The study did not account for the car's purchase price, its maintenance cost or associated tax credits.

Manufacturing an electric vehicle typically creates more pollution than making a traditional gas-powered one. But experts say that driving an EV over the long-term is still less polluting than a gas car.

Once they both drive about 15,000 miles (24,000 km) -- slightly more than the average American drives in a year -- the total pollution that has gone into making and driving each type of car has evened out, said Peter Slowik, U.S. Passenger Vehicles Lead for the International Council on Clean Transportation. Every mile after that widens the gap between the cleaner electric car and the more pollutive gas car. By the end of the car's life, emissions caused by the average EV are roughly half the average gas car, according to the U.S. Department of Energy.

So unless you buy a new car each year, the EV is the cleaner choice, he said.

"They are a no-brainer," Slowik said. "Electric vehicles are already inherently so much more efficient."

A 2023 analysis by Yale Climate Connections found that electric vehicles are responsible for less carbon dioxide pollution even in areas where the electricity used to charge them comes from coal. An EV in West Virginia, which is one of the most coal-reliant states, still pollutes 31% less than an equivalent gas-powered car, according to the analysis.

Slowik said that is because electric cars are better at translating energy into forward motion. For example, the most popular EVs in the US, the Tesla Model Y and the Tesla Model 3, can drive more than 100 miles (161 km) on energy equivalent to what is provided by a gallon of gasoline.

"If you compare that to a 25-mpg gasoline vehicle, that's already four to five times more efficient," Slowik said.
