The lifetime CO2 footprint of this niche trailblazer is likely lighter than that of almost any gasoline truck—while it outmuscles them all.

The first GM EVs built on its new-generation tech for battery electric vehicles are going out to customers.

GMC says that the electric Sierra will be GMC’s third EV, after the 2022 Hummer EV pickup (SUT) and the 2024 Hummer EV SUV.

There might be a connection once again between a civilian Hummer and a military vehicle—if the government is convinced on its worth.

The 2022 Hummer EV Edition 1 has all the bells and whistles, but underneath is the powertrain and platform for GM to create a full line of electric pickups.

The fully electric Hummer will allow a lot of flexibility with its off-road prowess, from Extract Mode to the option for one-pedal driving that might compare to a low range.

Keeping charging time short will be one of the core competencies for this off-road supertruck, as much as its performance.

More than 100 years ago electric trucks represented a significant piece of the brand's business.

GM revealed prototype photos of the Hummer EV in profile, plus new information about the electric truck's modes.

The GMC Hummer EV boasts 1,000 horsepower, 11,500 pound-feet of torque, and 0-60 mph in 3.0 seconds.

What our corner of the world seems to be waiting for is electric pickups. We check out the best deals on hybrid, plug-in, and electric cars for this month. And a new report shows how much enforcement efforts have slacked off at the EPA under President Trump. All this and more on Green Car Reports...

When it comes to reducing emissions, fleet operators generally have fewer options than individual buyers of passenger cars. There are fewer zero-emission vehicle options for vehicles that see commercial use, although those vehicles often cover more miles every year than the average passenger car...

Which 2016 pickup truck is the most fuel efficient?

GM has started production of its two new bi-fuel options in the pickup truck market. The 2013 Chevrolet Silverado HD and 2013 GMC Sierra 2500 HD bi-fuel models are able to run on either regular gasoline, or compressed natural gas (CNG). A 6.0-liter V-8 as found under the hood of each truck isn't...

If you want a green truck at the moment, your options are limited. By their nature, trucks require large engines, and large engines use a lot of fuel. Until electric and range-extended trucks become a realistic proposition, your best option is either hybrid, or alternative fuels--such as GM's...

With gas prices above $4 a gallon (at least this week), we've entered a familiar cycle. Man-on-the-street interviews feature wailing and moaning about how politicians "should do something" about gas prices. Drivers start to combine their trips, and make sure to use their most fuel-efficient...

Among the many substances emitted by autos back in the "good old days" were the refrigerant gases that would leak from older auto air conditioners. Freon, also known as R-12, was replaced starting in the early 1990s with R-134a, which did less damage to the ozone layer. Now concern has expanded to...

The Two-Mode Hybrid system for large sport utilities and trucks hasn't exactly set the world on fire. In 2006, General Motors, Daimler and Chrysler (then a single company) announced a partnership, soon joined by BMW, to develop the Two-Mode Hybrid system for large rear-wheel drive vehicles. But...

Our reader Celeste wrote to ask us about available hybrid SUVs and crossovers, and we thought our answer might be useful for the site. At the moment, there are three main hybrid SUVs sold in the U.S. Each of them also has variations sold under other brands. All are likely to be durable, as their...

Going green on the road may involve smaller engines, electric cars, and clean diesels, but it also requires making all engines far more fuel efficient. To that end, General Motors will announce this morning that it will invest almost one billion dollars in five separate plants to build a new, far...
