1As electric vehicles become more popular in the United States, a government safety expert is expressing concern about the automobiles.
2Jennifer Homendy runs the National Transportation Safety Board, or NTSB.
3In a recent speech, she noted that manufacturers are making electric cars heavier and heavier.
4This is a problem in crashes with lighter, traditional cars.
5She gave the example of one large vehicle called a Hummer.
6The automobile's design is based on military vehicles.
7The new electric Hummer weighs about 4,000 kilograms.
8The battery that powers it weighs 1,300 kilograms.
9The battery alone is heavier than the Honda Civic, a small Japanese car with a traditional engine.
10Homendy said she is worried about "increased risk of severe injury and death for all road users."
11She noted the size and power of the newer vehicles.
12The electric vehicles need large, heavy batteries in order to travel the longer distances many drivers seek.
13Experts say it will take years to develop smaller batteries that provide the same result.
14Homendy said she is pleased that President Joe Biden wants to reduce the number of vehicles that harm the environment.
15But she is still concerned about the risk from heavy vehicles.
16"We have to be careful that we aren't also creating unintended consequences," she said.
17Some of the new electric vehicles that are expected to be popular include Ford's F-150 truck and Mustang Mach E.
18She said they are hundreds of kilograms heavier than their gasoline-powered versions.
19The NTSB investigates accidents but does not make rules.
20New rules must come from the National Highway Traffic Safety Administration.
21Michael Brooks runs the Center for Auto Safety.
22He has the same concerns as Homendy.
23He said there has been little research about the growing weight of electric vehicles.
24He pointed to a 2011 study that showed a crash including a vehicle with about 500 extra kilograms increased the chances of death by 47 percent.
25That study does not take into account design changes that make it hard to see from the new electric vehicles.
26He also said the electric vehicles can reach top speed faster than gas-powered cars.
27"These bigger, heavier batteries are going to cause more damage," Brooks said.
28"It's a simple matter of mass and speed."
29The number of electric vehicles sold in the U.S. in 2022 rose by almost 65 percent compared to the year before.
30They now make up nearly six percent of new vehicles on the road.
31The number of vehicles with heavy batteries will only grow.
32Biden's administration wants electric vehicles to be 50 percent of all new vehicles sold by 2030.
