This case study shows that the actual CO2 reductions of 18.6% achieved in the 2018 Camry exceed the 17.7% reductions predicted by EPA models. This confirms that the OMEGA and LPM models accurately predict both new technology benefits and synergies between technologies. It also suggests that other studies contradicting EPA model outcomes are inaccurate and underpredict future technology benefits.

Explores some of the compliance pathways available to heavy duty vehicle manufacturers. Specifically, this paper develops hypothetical technology packages for certain types of tractor trucks, vocational vehicles, and trailers using distinct technology strategies compares cost-effectiveness.

Investigated the impacts of updating three standards in Mexico to align with the international best practices employed in the rest of North America: gasoline and diesel sulfur standards, passenger vehicle emissions standards, and truck and bus emissions standards.

This paper compares fuel consumption / CO2 values of passenger cars from different sources and aims at quantifying the discrepancy between laboratory type-approval values and real-world values, including a retrospective analysis for the years 2001-2011 to determine if the gap between the two datasets has increased over time. Potential explanations for the discrepancies found are discussed and possible practical solutions for the future outlined.
