What No One Tells You About Vehicle Weight and Pollution

Episode 300 of SAE Tomorrow Today marks a milestone with a powerful conversation on the hidden costs of going green. Authors Nick Molden and Felix Leach dive into insights from their book Critical Mass, revealing why vehicle weight—not just tailpipe emissions—is the key to understanding environmental impact. As EVs tip the scales at 700 pounds more than combustion cars, they're driving up tire pollution, road wear, and non-exhaust emissions. The duo also propose a bold solution: a weight-based tax system to push the industry toward lighter, truly sustainable vehicles.
