Summarizes policies and actions that are expanding access to electric transportation in the United States and showcases several examples of equity-focused electric mobility practices that are encouraging their utilization more widely.
Reviews the structure of EPA’s emission recall program for light-duty vehicles and trucks (LDV and LDT) and its effectiveness over time and also explains the recall authority, procedures, and coordination among offices.
Identifies key differences in the regulations governing certification of NOx emissions from diesel cars (Euro 6) and trucks (Euro VI) that help explain differences in their real-world emissions performance. Ultimately, an examination of the HDV regulation reveals insights that could be used to improve the LDV regulation.
This technical brief highlights important innovations and trends in downsized and turbocharged gasoline engines, several of which were not considered when the 2025 CAFE standards were finalized, but promise to be quite cost-effective.
A concise overview of the EU's vehicle CO2 emission reduction requirements, targets for 2025–2030 that are coming under consideration, and current best projections of vehicle-specific CO2 reduction technology potential and costs in that time frame.
Highlights developments in technologies that contribute to vehicle fuel efficiency by improving control of heat in the powertrain and the passenger cabin. Few thermal management technologies were explicitly incorporated into the technology projections for the US 2025 CAFE standards.
One in a series of technical briefs highlighting important innovations and trends in transmissions, which, overall, are similar to efficiency benefits and cost projections made at the time the 2025 CAFE standards were finalized.
One in a series of technical briefs highlighting important innovations and trends in "conventional" automotive technologies, which are significantly outpacing projections made at the time the 2025 CAFE standards were finalized.
Makes recommendations for how India should use checks of on-board diagnostic systems (OBD) to identify malfunctioning emissions control systems in new vehicles and to lower the burden on the country’s testing facilities.
