General Motors says the Trump administration forecasts that its technology costs through 2031 will fall by $20.4 billion because of lower fuel economy standards, according to a document.
The rule change stems from a broader reset of fuel economy standards that the National Highway Traffic Safety Administration first proposed in December 2025. As part of that overhaul, the US plans to end the trading of fuel economy credits in 2028, ending a system automakers had used to offset shortfalls in efficiency across their fleets.
The savings come as GM faces other pressures. The company warned on its US business between September 24 and 26, as Detroit automakers lose ground to Asian rivals. The Trump administration has also moved to tighten other rules affecting the auto industry, including tariffs and criticism of automakers' supply chain choices.
The $20.4 billion figure is real, but it offsets rather than outweighs those near-term costs. Tariffs and the capital GM needs for domestic production weigh against the compliance savings, leaving the forecast as a partial cushion rather than a clear reason to expect stronger results.
