  • If you think driving a pint-sized Nissan Leaf is as good for the planet as driving a giant electric Hummer, think again.
  • The GMC Hummer EV uses significantly more power than other EVs. That means more pollution upstream.
  • The electric Hummer weighs 9,000 pounds, battery Same weight as Honda Civic.

The new electric Hummer zips through town without deafening engine roars or toxic fumes, but it’s not nimble.

The giant truck weighs a whopping 9,000 pounds. (Think 2 Toyota Tacomas, 3 Honda Civics, or 24 Shaquille O’Neals.) Plus, the GMC Hummer EV is, in many ways, a new-age super-large gas guzzler. It repackages many of the same flaws of the giant SUVs and trucks of years ago, proving that not all zero-emission vehicles are created equal.

EVs can also be energy consumers

Overall, electric cars consume less energy than petrol cars. But they are not all equally efficient.

The Hummer needs more power than any other EV on the market to power its elephant-like frame.Environmental Protection Agency We rate the pickup at 47 MPGe. (miles per gallon of gasoline equivalent).For comparison, the Tesla Model 3 sedan is about 3 times more efficient, with a rating of 132 MPGe. Another electric truck, the Ford F-150 Lightning, gets 70 MPGe.

This has real consequences. 61% of energy from oil, coal and natural gasthe more power a car requires, the more pollution it creates upstream.

As The Union of Concerned Scientists stated that“Electric cars and trucks are both much cleaner than gas-powered cars, but electric trucks contribute more global warming emissions than electric cars simply because trucks are bigger and heavier. ”

Building a Hummer EV takes a lot of resources, and it takes a huge (and heavy) battery to get the 300+ miles of range people want.you can produce 3 Chevrolet Volts It uses the same battery cells that one Hummer consumes.And raw battery materials like lithium are already short of.

“If you reallocated everything that went into a £3,000 Hummer EV battery to sedans and more reasonably sized cars, how many more reasonably sized electric cars could you make? David ZipperA visiting fellow at the Harvard Kennedy School’s Taubman Center for State and Local Government told Insider.

4.5 ton elephant in the room

Hummer EV is full 4,000 pounds heavier Better than a gas-powered Ford F-150 with plenty of options. And it’s even chunkier than the original military-inspired Hummer H1 that put the brand on the map.it’s so massive Not allowed on the Brooklyn Bridge General Motors is not required to display EPA efficiency stats on window stickers.

The extra weight and size of a vehicle doesn’t just add to its inefficiency. According to research, it also Increased emissions due to tire and brake wear When Greater risk to others in a crash (both bigger blind spot When just physics).

In response to questions about all this, a GM spokesperson said the Hummer EV is intended to be a so-called “halo car” that demonstrates the potential of EVs.She also noted that GM engineers considered mass when designing the truck’s brakes and other systems, and talked about their safety features. Research attribute She added that there has been a recent spike in pedestrian fatalities caused by factors other than heavy vehicles, such as drunk driving, speeding and poor infrastructure.

The new Hummer isn’t unique here. All battery-powered cars are heavier than petrol cars, but the largest.

Indeed, for Americans to switch to electric vehicles, they must be presented with many options across the automotive spectrum. Lifted Diesel He’s not a truck driver suddenly accepting a cute little hatchback.Studies show that electrification of pickup trucks Significant reduction in greenhouse gas emissions Rather than doing the same for a smaller car.

Still, some transportation experts believe more needs to be done to keep buyers away from the giant, energy-hungry EVs. Zipper is a proponent of weight-based pricing, already in place in Washington DC and Norway, a country at the forefront of the EV movement.

“People should be free to buy what they want, but we need to make sure the market forces them to pay the costs their decisions can impose on society.
