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.
Upgrades to Vietnam's first and only refinery, expected to begin production of Euro 5 diesel and gasoline in 2016, will lower the country’s reliance on imports and allow for the domestic production of clean fuel.
Compares official fuel consumption values with real-world performance for 20 popular vehicle models. Officially, fuel consumption gains in these 20 models ranged from 8% to 30%. But on-road measurements indicate that 8 of the 20 showed little to no improvement in real-world fuel efficiency.
Explains the methods used to construct a global database of historical vehicle sales and facilitate the development of sales-based metrics that track progress toward clean vehicle policies and technologies.
