It will be the first time more than 1 million EVs are sold in the U.S. in one calendar year, probably reaching between 1.3 million and 1.4 million cars, the research firm predicts.

Although the numbers show significant progress for electrification, the nation is lagging behind countries like China, Germany and Norway.

EVs reached 33% of sales in China, 35% in Germany, and 90% in Norway for the first six months of 2023, according to a BloombergNEF EV outlook published in June. These figures include both battery electric vehicles and plug-in hybrid EVs.

In those countries, ambitious government zero-emissions targets, vehicle tax incentives and subsidies, and affordable options play a role in a consumer’s decision to adopt a plug-in vehicle.

Several factors helped boost U.S. EV adoption this year, but in a word, prices have gone down.

Tesla, the current EV market leader, dropped the prices for its popular vehicles multiple times throughout the year. This forced other automakers to try to keep up. Car companies are also now offering greater incentives on their electric models, and dealers are discounting more deeply as EV supply builds up at dealerships.

The Inflation Reduction Act, which increased tax credits for qualifying new and used EV purchases, also helped bring EV costs down for buyers, by $3,750 or $7,500, depending on certain requirements.

Electric car battery costs are also falling as critical battery materials like lithium get less expensive, making the vehicles increasingly affordable, too.

But even as U.S. EV market share grows steadily, hurdles still stand in the way for some car buyers considering electric. Early EV buyers were largely higher-income, willing to try unfamiliar technology, and more likely to be able to charge their electric vehicles at home. The auto industry needs to address disparities with these factors as it targets the next wave of EV shoppers.

For many consumers, unreliable and inaccessible public charging infrastructure, as well as the increased upfront cost of going electric, remain barriers, according to BloombergNEF. Last month, new EVs still cost on average $3,826 more than the average new car, going for $51,762 versus $47,936, Kelley Blue Book estimates.

To combat some infrastructure challenges, several major automakers have signed on to Tesla’s charging technology. Tesla has long used the North American Charging Standard for its EV plugs, and it has also had the strongest public charging network. The rest of the industry has largely operated on one called CCS, or the Combined Charging System. Incorporating Tesla’s tech will give non-Tesla EV drivers more opportunity to charge elsewhere, and alleviate charging concerns. But those changes won’t start to kick in until next year and 2025.

The industry is also grappling with concerns over an EV market slowdown. Some automakers, including Ford Motor Co. and General Motors, are scaling back on their electrification targets.

But at the same time, many non-domestic car companies are amping up their plans. Consumers can expect Chinese EV-makers such as BYD to find their way to the U.S. market in the coming years.

Several U.S. states have set target dates by which they expect vehicle sales to be majority zero-emissions. California and Washington have mandated that 100% of new vehicles sold in the state be zero-emission by 2035, while New Jersey will ban the sale of new gas-powered vehicles by that same year.
