Electric cars tend to need extra bulk for their gigantic battery packs, and that’s raising eyebrows at the National Transportation Safety Board. In a keynote speech<\/a>, NTSB chair Jennifer Homendy said she was worried the size and weight of modern EVs could increase the risk of serious injuries and death. A Hummer EV<\/a> is over 9,000lbs, the board leader said, while electrified versions of vehicles like the Ford F-150<\/a> and Volvo XC40<\/a> are far heavier than their gas engine equivalents.<\/p>\n

Homendy stressed that she supported the Biden administration’s environmental goals<\/a>, and that transportation represented the largest contributor to American greenhouse gas emissions. She just felt that automakers had to be wary of creating “unintended consequences,” such as more road fatalities.<\/p>\n

<\/p>\n

There is some data to suggest that EVs’ added weight may pose a danger. Green Car Congress<\/em>pointed<\/a> to a 2021 commentary<\/a> in Nature<\/em> where researchers calculated that the mortality costs of the F-150 Lightning’s extra 700kg (1,543lbs) over the gas model ‘rival’ its zero-emissions benefits. The chances of passengers dying in a collision increase 12 percent with every 500kg (1,102lbs) of weight difference, the research team said. While those issues might diminish as more EVs reach the market, they could remain a problem as long as combustion engine and electric cars have to share the road.<\/p>\n

Technical solutions might help. Scientists are already developing lighter batteries<\/a>, and the first EVs with denser solid-state batteries<\/a> (which can achieve similar range with smaller packs) are only a few years away. While EVs with this technology are still likely to be heavier than their fossil fuel-burning counterparts, the weight reduction could improve safety in addition to range.<\/p>\n
