“Despite a modest uptick in ICE market share in Q4, the longer-term trend remains clear. From 2016 through 2025, traditional ICE share steadily declined. In 2016, ICE vehicles accounted for more than 97% of all light-duty sales; by 2025, year-to-date share had fallen to 72.9%, a cumulative decline of 24.2 pp (including a 3.1 pp drop from 2024 alone).That shift has been absorbed by alternative powertrains. Traditional (mild and strong) hybrids captured the majority of the gains (+15.5 pp), followed by BEVs (+7.4 pp) and PHEVs (+1.3 pp) over the past nine years,” AAI said.
