Hyundai's second-place finish is particularly noteworthy in light of the fact that its vehicles are not subject to the federal EV tax.
Unless they are leased, federal EV tax credits are up to $7,500.
The purpose of these complicated incentives is to support EVs made in North America.
Hyundai presently imports its EVs from abroad.
Under the Inflation Reduction Act of the Biden administration, the automaker with headquarters in South Korea has been taking use of that lease loophole.
To start this year, the Hyundai brand has raised leasing of its electric vehicles from about 2%.
Randy Parker, CEO of Hyundai Motor America, the Hyundai brand has already surpassed 30%.
Sales of EVs by General Motors have so far been underwhelming, particularly for new cars equipped with the company's "Ultium" battery technologies.
