Evaluates the effect of Euro VI-equivalent emissions standards on bus system costs in Brazil.
Highlights important innovations and trends in vehicle design technology and lightweighting, many of which were not considered when the 2025 CAFE standards were finalized, but promise to be quite cost-effective.
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.
Comprehensive technical overview of the Euro 6/VI vehicle emissions standards, looking at the historical context of the European regulations and considering what is likely to come next.
Summary of provisional data from the European Environment Agency. Average CO2 emissions from new cars sold in the EU in 2015 were 119.6 g CO2/km, 8% below the 2015 target and 3% lower than in 2014.
