What the electric Hummer's size and weight means for its efficiency

The 2022 GMC Hummer EV Edition 1. Tim Levin/Insider If you think driving a pint-sized Nissan Leaf is as good for the planet as driving a huge electric Hummer, think again.  The GMC Hummer EV uses significantly more electricity than other EVs, meaning it produces more pollution upstream.  The electric Hummer weighs 9,000 pounds and its battery weighs as much as a Honda Civic. The new electric Hummer rolls through town without a deafening engine rumble or a cloud of toxic fumes, but it doesn't exactly tread lightly.  The colossal truck weighs an astonishing 9,000 pounds. (Think two Toyota Tacomas, three Honda Civics, or 24 Shaquille O'Neals.) Moreover, the GMC Hummer EV is in many ways a supersized gas guzzler for a new era. It repackages many of the same flaws of hulking SUVs and trucks of years past — and proves not all zero-emission cars are created equal. EVs can be energy guzzlers too On the whole, electric cars use less energy than gas-powered ones. But they aren't all equally efficient.  No surprise here: The Hummer needs more electricity than any other EV on the market to move its elephantine frame. The Environmental Protection Agency rates the pickup at 47 MPGe (miles per gallon of gasoline-equivalent). For comparison, the Tesla Model 3 sedan is nearly three times as efficient, earning a rating of 132 MPGe. The Ford F-150 Lightning, another electric truck, gets 70 MPGe.  This has real consequences: Since the US gets 61% of its energy from oil, coal, and natural gas, the more electricity a car needs, the more pollution it creates upstream.  As the Union of Concerned Scientists put it: "Both EV cars and trucks are much cleaner than their gasoline counterparts, but electric trucks are responsible for more global warming emissions than electric cars simply because trucks are larger and heavier."  The 2022 GMC Hummer EV Edition 1. Tim Levin/Insider The Hummer EV is also resource-intensive to manufacture, requiring a ginormous (and weighty) battery to give people the 300-plus miles of range they desire. You could produce three Chevrolet Bolts with the same battery cells consumed by one Hummer.

2019 GMC Sierra AT4 gives Raptor and Ram a new off-road rival

The 2019 GMC Sierra AT4 blends off-road hardware into a modern, thoroughly updated pickup truck that doesn't skimp on power, luxury, or safety equipment. From its higher suspension setup to its available carbon-fiber cargo bed and the new MultiPro tailgate, the 2019 Sierra AT4 is a direct shot across the bow — or cargo beds, if you prefer — of staunch rivals like the Ford F-150, Dodge Ram and Toyota Tundra. Revealed tonight in New York City, ahead of this week's New York International Auto Show, the truck may seem to be in a strange setting. Then again, with the amount of tire-swallowing potholes currently scattered around the Big Apple, a rugged truck like the Sierra AT4 could be the perfect vehicle for either off-road excursions or an especially bumpy commute. Riding two inches higher than the standard 2019 Sierra, the AT4 comes with standard features like all-wheel-drive with a two-speed transfer case, locking rear differential, Rancho monotube shock absorbers designed specifically for off-roading, along with skid plates and 18- or 20-inch alloy wheels fitted with all-terrain tires or optional, mud-loving Goodyear Wrangler Duratecs. Hill descent control and GMC's Traction Select system are also standard. The latter of these two lets the driver choose between preset drive modes, suitable for various types of terrain and weather conditions. The system then adjusts throttle response, shift points, and the electronic stability control according to each mode.

"It's also the beginning for the AT4 brand, which will be seen on every vehicle in our lineup in the next two years." Based on the new 2019 Chevrolet Silverado, the GMC Sierra (including the AT4 model) looks to stand out from its corporate cousin in terms luxury touches, along with some subtle exterior details. For the AT4, these visible differences include a body color grill surround and bumpers. Meanwhile, the inner grille, front fog-lights and faux fender vents feature a black-chrome finish. It's not flashy, which is probably exactly what GMC wanted for its upscale truck. The standard engine is a 5.3-liter V8, though buyers can choose an optional 3.0-liter turbo-diesel inline-six or 6.2-liter V8.

These are the 10 longest-lasting vehicles on the road today

Buying a car has started feeling pretty bad. It’s hard to find what you want, and when you do, thereÂ’s a great chance itÂ’s not selling for the price you thought it would be. The least stressful way of coping with the situation is not to buy a new car, but how can you know how long your current ride will last? A recent study from iSeeCars found that some vehicles are prone to deliver many more miles of usable driving than others. iSeeCars looked at more than 2 million cars. The mileage over which the top 1% of cars within each model obtained was calculated and used to rank models, and the study required that a vehicle be sold for at least 10 of the past 20 years to be included. Unsurprisingly, Toyota dominated the top-10 list, but most of the other models come from General Motors with one Honda thrown into the mix. Ranked by mileage, the top-ten longest-lasting vehicles include: Toyota Highlander Hybrid: 244,94 miles Toyota Avalon: 245,710 miles Honda Ridgeline: 248,669 miles Chevrolet Tahoe: 250,338 miles Toyota Prius: 250,601 miles GMC Yukon XL: 252,360 miles Toyota Tundra: 256,022 miles Chevrolet Suburban: 265,732 miles Toyota Land Cruiser: 280,236 miles Toyota Sequoia: 295,509 miles The iSeeCars study found that SUVs and trucks occupy 75 percent of the top 20 vehicles with the potential to last the longest, and Toyota alone accounts for half of the top 20. Interestingly, the Prius and Highlander Hybrid made the list, suggesting that automakers are getting better at making batteries last a long time. "What we see is a list of highly-durable vehicles, capable of more than a quarter-million miles of use if properly maintained," said iSeeCars Executive Analyst Karl Brauer. "And to be clear, this study isnÂ’t reporting the maximum lifespan of these vehicles. This is simply a measure of current odometer readings. Most of these cars are still in use and going strong." Of course, the longevity of a vehicle has a lot to do with how itÂ’s treated and maintained over its lifetime. ItÂ’s easy to find stories of people nursing Toyota Tundras and other vehicles past a million miles, and thereÂ’s a 1960s Volvo with more than 3 million miles. Some vehicle types, particularly the largest SUVs, are often used as road-trip vehicles by large families, which means they tend to rack up big mileage. In most cases, buying and owning a higher-mileage car can be a risk, so itÂ’s essential to get a pre-purchase inspection or regular maintenance if you already own one.
