2022-2025 Proposed Fuel Economy Standards


The mid-term review of the proposed fuel economy standards for the 2022 to 2025 time frame is currently prepared in the US. This includes assessing the rate of technology development since the technology assessments that the Agencies (EPA, CARB, NHTSA) undertook almost 4 years ago for the 2017-25 standards. This research, which will be published in a series of technology briefings will evaluate recent technology developments and progress rates with respect to the targets in the 2025 fuel economy and GHG rule. Each technology brief will evaluate a number of parameters such as technology penetration rates, cost reductions, improvement in vehicle fuel economy, customer acceptance issues, real-world fuel economy, performance, drivability, reliability, and safety.
