General Motors Chief Executive Mary Barra said the automaker will continue to improve the efficiency of its combustion engines even as recent U.S. regulatory changes sharply reduce penalties for missing federal fuel-economy targets, a move that has eased pressure on the industry.
The U.S. Environmental Protection Agency this year effectively removed financial penalties tied to shortfalls in fuel-economy compliance, giving automakers greater flexibility in shaping their product portfolios. The change could encourage renewed emphasis on larger, higher-margin trucks and sport utility vehicles, which have historically faced less stringent efficiency requirements.

Speaking at the New York Times DealBook Summit on Wednesday, Barra said GM remains committed to improving the performance of internal combustion engines regardless of the regulatory environment. “Every engine we invest in, we work to have a significant improvement,” she said.
Industry analysts say tougher fuel-economy standards in recent years have added substantially to automakers’ costs, with some industry reports linking several large recalls over the past two years to the engineering complexity created by those rules. With penalties now reduced, questions remain over whether automakers will sustain the same pace of efficiency gains, particularly as demand for large SUVs and pickup trucks continues to dominate the U.S. market.

Barra also voiced support for the Trump administration’s decision to revoke California’s authority to set its own, stricter vehicle emissions standards, backing instead a single national framework. She said a unified approach would avoid regulations that “get in front of the consumer.” At the same time, she acknowledged that shifting market conditions have become more challenging as incentives for electric vehicles have been reduced and GM’s EV business has yet to reach profitability.
Despite softer regulations, Barra said GM remains committed to electric vehicle development. She was more optimistic about recent tariff policies, saying they had created “a more level playing field” after years of uneven global trade barriers. Analysts say that while engine refinement may continue, weaker rules and strong consumer demand for large vehicles could reinforce Detroit’s reliance on its most profitable segments.
