Electric cars are heavier than petrol and diesel cars, so they are safer

The battery pack is very heavy, so an electric car is usually heavier than a similar model with a gasoline or diesel engine.

This has important safety consequences, but is far more complicated than commonly thought in terms of mass and speed problems.

For example, the GMC Hummer EV electric pickup model Edition 1 has a lot of batteries to increase power and travel per charge, so the vehicle weight is about 4,082 kg.

In the event of a collision, this extra weight helps the occupants of the vehicle. Insurance claims statistics show that electric vehicle users tend to be less injured than those of similar models with gasoline engines.

No longer a large metal engine block in front, the electric car has more free space. But the trend of injury claims is also with hybrids, according to the Insurance Institute for Highway Safety (IIHS). Hybrids are also heavier due to the weight of the battery and still have an engine under the bonnet.

But the fact that the vehicle is heavier can be bad news for those hit by the tram, because the force of the impact will be reflected towards the lighter vehicle.

Why heavier is better, but only for the person inside

Simply physics. When two moving objects collide, the heavier one will tend to move more, more or less, in the direction it is traveling. But the lighter will change direction very suddenly. Even though the lighter car didn’t crash, the deflection was bad enough for the occupants. Meaning, the occupants of the heavier vehicle are just as likely to be hit hard, and the vehicle’s excess mass could be lifeguards.

It’s not just the Hummer EV that’s very heavy. Other electric vehicles are also significantly heavier than the internal combustion engine version. The Ford F-150 Lighting electric pickup is 725 kg more than the petrol F-150. Similarly, the Volvo XC40 Recharge is 453 kg heavier than the petrol Volvo XC40.

The GMC Hummer EV Edition 1 has more mileage and power than any internal combustion engine version of this pickup. It also means that the car is equipped with a lot of batteries. This massive battery block, in addition to the details for an off-road vehicle, is the reason why the weight reaches 4,082 kg, according to Michael Farah, a representative of General Motors.

Heavier vehicles are not new, nor are they exclusive to electric vehicles. Average car weight has increased over the past 40 years, according to a report by the US Environmental Protection Agency (EPA), from about 1,450 kg to nearly 1,905 kg. That’s also because customers are increasingly turning to pickup trucks and SUVs, which are also often heavier.

Not just electric vehicles, but the difference between vehicles of different weights is also a key safety point. When a car and a truck collide, the difference in weight can have very different effects on the two sides.

Impact on the road surface

Heavier vehicles can impact road surfaces as well as bridges, but experts disagree that there is damage from this impact. Most roads, highways and bridges are designed to withstand the weight of huge trucks that are much heavier than electric cars.

David Orr from Cornell University’s Residential Sugar Program reassures, there’s no need to worry. Even the smallest local two-lane roads can easily withstand the weight of the GMC Hummer EV. Although residential roads often have more cars passing by, even heavier SUVs can’t damage the road.

Even if electric cars damage pavement faster than usual, that’s a small price to pay for the benefits of a cleaner environment, according to Doug Mensman, the city’s director of Transportation. Los Angeles street.

“If more frequent maintenance or rebuilding is required, that could be the price we, as well as society as a whole, have decided are willing to pay from the future budget to receive these benefits. “, Mensman said.
