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.

Watch the 2022 GMC Hummer EV launch using its Watts to Freedom mode

It’s nearly the July Fourth weekend, and GM is celebrating Independence Day a little earlier than most. The celebration comes in the form of a GMC Hummer EV demonstrating Watts to Freedom, or WTF, mode for us on video. You can watch it at the top of this post, but the idea is rather simple. ItÂ’s just a video of a Hummer development vehicle accelerating as quickly as it can from 0-60 mph and beyond. GMC claims its 1,000-horsepower electric Hummer is capable of hitting the 0-60 mph mark in “approximately 3 seconds,” which is borderline terrifying for how large of a vehicle it is. The super-quick time is possible when using the Watts to Freedom launch control mode, which “channels the propulsion systemÂ’s tremendous power into acceleration bursts.” The truck will still be plenty fast when accelerating normally, but WTF mode is what you should use to unlock its full potential. GMCÂ’s video shows us the graphics it uses in the digital cluster to signal Watts to Freedom is activated, and the whole sequence looks like it leans on U.S. military themes for both design and phrasing. For example, GMC lets you know that Watts to Freedom is ready via an “Armed” message in the cluster.  The 2022 GMC HUMMER EV is a first-of-its kind supertruck develop View 40 Photos Instead of a rumbling exhaust and screeching tires, the Hummer appears to silently launch with all four tires grabbing on and catapulting the truck away. It looks quick as it throws all of the weight rearward into an accelerative squat. And in case you missed it, thatÂ’s a lot of weight — GMC says itÂ’ll tip the scale at 9,046 pounds. GMC has previously said that production will begin in late 2021, and this video continues to confirm that timeframe with a note saying “initial availability Fall 2021.” Do keep in mind that only the sold-out Launch Edition is coming at that time. Other cheaper variants will follow in the years to come. Related video: This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.

Mil-Spec 003 First Drive Review | The ultimate Hummer H1

We're in something of a golden age for automotive restomodding, and into a heady mix that includes Singer's reimagined 911s, Icon's fancy off-roaders, and lots of updated Land Rovers. The latest company with ambitions to become a top-tier custom car brand is Mil-Spec, which aims to do what the aforementioned companies do, but with the big, brash, blunt Hummer H1. And in particular, the company is aiming to make its Hummers a compelling alternative to a used Hummer H1 Alpha. The Alpha is generally considered to be the best of the breed with the most powerful diesel engine offered, larger brakes, and a nicer interior compared with its predecessors. To find out whether the company's early efforts live up to that ambition, Mil-Spec invited us to drive their third completed vehicle, Mil-Spec 003. It started life as a 1995 Hummer H1, and as with all of Mil-Spec's vehicles, it was completely disassembled, and the body and frame media-blasted down to metal. The frame and related components are then powder-coated with a black gloss finish. The truck's aluminum body, in this case a four-door hardtop pickup variant, but is coated in a resilient bedliner-like material designed for easy care. Bits of Kevlar are mixed in with the material for strength, and it can be tinted different colors and have rougher or finer textures. Underneath the body, one of the five different engines that were available on the H1, usually a diesel V8, is replaced with a 6.6-liter Duramax LBZ turbodiesel V8. This engine was available on heavy duty Chevy and GMC pickup trucks, and a related engine was used in the Hummer H1 Alpha. Whereas the engine in the H1 Alpha made 300 horsepower and 520 pound-feet of torque mated to a 5-speed automatic, the Mil-Spec's LBZ has had turbo upgrades and a different ECU tune allowing it to produce 500 horsepower and 1,000 pound-feet of torque. It's also coupled to an Allison 1000 6-speed automatic transmission. The mechanical upgrades don't stop with the engine and transmission. The inboard brakes are given drilled and vented discs, and an ARB Air Locker locking rear differential fitted. Dual auxiliary transmission coolers also make an appearance and can be switched on as needed. The 003 received 20-inch wheels with 38-inch mud terrain tires, but larger tires can be added if desired.
