After a precipitous drop from 1976–1982, the weight of US passenger cars has grown steadily. This article examines multiple conflicting influences on vehicle weight in two categories: technological changes that reduce vehicle weight and improvements in functionality that, ceteris paribus, add to vehicle weight. The widespread adoption of unibody construction, lightweight materials and smaller engines has been offset by growth in vehicle size and feature content. The best estimates from this… 

Future Vehicle Types and Characteristics: Reducing fuel consumption through shifts in vehicle segments and operating characteristics

Light duty vehicles represent a notable target of regulation in the United States due to their environmental, safety, and economic externalities. Fuel economy regulation represents one of the more

This study used a matched data set drawn from more than 1 million new vehicle postpurchase consumer satisfaction surveys to test for differences in satisfaction and reasons for vehicle choice and

The Importance of Powertrain Downsizing in a Benefit–Cost Analysis of Vehicle Lightweighting

Reducing vehicle weight is an important avenue to improve energy efficiency and decrease greenhouse gas emissions from our cars and trucks. Conventionally, models have estimated acceptable increased

Travel Effects and Associated Greenhouse Gas Emissions of Automated Vehicles

The author outlines the mechanisms by which AVs may change travel demand and review the available evidence on their significance and size, as well as the results of scenario modeling studies.

Green Principles for Vehicle Lightweighting.

A set of 10 principles, based on a life cycle perspective and taken as a set, allow a wide range of stakeholders to evaluate the trade-offs inherent in these complex systems and help avoid shifting of burdens to other life cycle phases in the process of improving use-phase environmental performance.

Impacts of Autonomous Vehicles on Greenhouse Gas Emissions—Positive or Negative?

Study findings reveal that the positive emission changes may not be realized at a lower AV penetration rate, where the maximum emission reduction might take place within 60–80% of AV penetration into the network.

Automated Vehicle Scenarios: Simulation of System-Level Travel Effects Using Agent-Based Demand and Supply Models in the San Francisco Bay Area

The effects of automated vehicles using the San Francisco Bay Area Metropolitan Transportation Commission’s activity-based travel demand model (MTC-ABM) and the MATSim dynamic assignment model to simulate different “first” mile transit access services provide insight into the relative benefits of each service and automated vehicle technology and the potential market for these services.
