EVs need to be lighter, profs urge

Electric vehicles are too heavy, creating a greater risk for death in a collision, a trio of professors warned in a recent paper.

Electric vehicles are growing in popularity with expectations of them making up half of all vehicles sold in the U.S. by 2035. Canada announced a sales ban on fuel-powered vehicles for 2035 as well.

But, bulk batteries replacing internal combustion power means that the rest of the vehicle needs to be heavier to provide the needed structural support, say Blake Shaffer, an assistant professor in the department of economics and school of public policy at the University of Calgary, Maximilian Auffhammer, a professor at the University of California, Berkeley and at the National Bureau of Economic Research in Cambridge, Massachusetts, and Constantine Samaras, an associate professor in the department of civil and environmental engineering at Carnegie Mellon University in Pittsburgh.
