Electric vehicles bring massive torque and zero tailpipe emissions, but they introduce a severe infrastructure problem due to their sheer mass.
The battery penalty
Because of the relatively low energy density of lithium-ion compared to gasoline, a battery pack adds hundreds of kilograms to a vehicle. An average EV weighs 20% to 30% more than its internal combustion counterpart.
Tire wear and pollution
Instant torque combined with immense weight burns through tires significantly faster. This releases a high volume of microplastics and particulate matter into the environment, offsetting some of the local emissions benefits.
Infrastructure strain
Older multi-story parking garages were engineered with specific weight limits in mind. As EV adoption grows, structural engineers are raising alarms about the cumulative load of dozens of 7,000-pound vehicles parked on a single suspended deck.
The regulatory blind spot
Highway guardrails and crash safety standards are only just beginning to account for the kinetic energy of heavy EVs. A standard guardrail designed in the 1990s will not stop a modern electric truck traveling at highway speeds.
