GM planning to put its fullsize pickups on a big diet, too

General Motors is just coming off a complete redesign of the Chevrolet Silverado and GMC Sierra for 2014, but in the US fullsize truck market, there is no rest for the weary. According to Reuters, plans are already unfurling for both trucks to drop pounds from their curb weight over the next few years, but this will unlikely be able to keep pace with the 700-pound diet targeted for the next-generation Ford F-150, a truck expected to debut late next year.
The biggest weight reduction for these trucks might not be available until the next full redesign, which will likely happen around 2019, but the article says that smaller updates could shave pounds in the meantime. Two examples given include an "aluminum-intensive" version of the Silverado that could shed 250 pounds and debut around the same time as the lighter-weight, aluminum-bodied 2015 Ford, and there is also talk of reducing weight for driveline components such as axles and driveshafts. These changes are all part of an attempt to meet strict new fuel economy standards coming in 2017, targets which will get even tougher in 2025.

The biggest gas-guzzlers of 2024: 'The Meanest List' is the opposite of greenest cars

In some circles — especially some automotive circles — bigger is better. This explains the Hummer, for example. In its so-called “Meanest List” of a dozen models, the American Council for an Energy-Efficient Economy (ACEEE) makes no apologies for berating “the worst-performing mass market automobiles” sold in 2024 in the U.S. The most diminutive car on the list is a Chevy Corvette Z06. At the top of this particular heap is the Mercedes-Benz AMG G63, a gas-powered SUV that the environmental agency says was “the worst-performing vehicle of the more than 1,200 models assessed by Greener Cars and has an annual fuel cost over $4,000.” Not to mention its MSRP of around $184,000.

Lonely at the middle of the list is the sole electric, the GMC Hummer EV, which weighs in at 9,000 pounds. The council notes that “though EVs have lower emissions than similarly sized gasoline models, the Hummer demonstrates that size and efficiency, not just fuel source, are important factors in a carÂ’s environmental impact.” ItÂ’s also worth reminding prospective buyers that the average fuel cost of a vehicle on the “Greenest List” eats up only a fifth of the fuel cost of a vehicle on the Meanest List, “showing that greener options can also be more affordable.” The ACEEE also put out a "Greener List" of efficient gasoline and hybrid cars that don't require plugging in.  By the Numbers Green Cadillac Chevrolet Dodge Ford GMC Hummer Jeep Maybach Mercedes-Benz RAM Emissions Fuel Efficiency Green Automakers Truck SUV Electric Hybrid

GM crab walked the Hummer EV truck up and down Woodward this weekend

Sometimes, manufacturers like to show off their fancy new wares at the Woodward Dream Cruise. It’s largely done through static showcases with big displays for the public to gawk at. However, GM did something a little different with its GMC Hummer EV truck this year. Instead of parking it at the Chevy and GM display area, it took to Woodward Avenue itself to show off the Hummer in pre-production form. Not only did GM drive the electric truck on the road in front of thousands, but it crab walked the whole way. This was our first time, and probably most of the publicÂ’s first time seeing the Hummer EV crab mode in person. Judging from the crowdÂ’s reaction (GM got its wish of everybody paying attention), folks are impressed, and maybe a bit confused at the HummerÂ’s sideways movements.  ItÂ’s a strange spectacle to see in person. At first, the truck appears as though itÂ’s sliding sideways on ice in a smooth, graceful slide. ThatÂ’s because even though the wheels are turned, the front of the truck is still pointing dead straight ahead. The GM employee behind the wheel of the prototype appeared to be moving forward at about 5-10 mph — it appears shockingly quick in person for the way this behemoth of a truck presents itself. The tech making it work is rather simple in concept. GM simply took existing rear-wheel steering technology, then amplified and modified it for this type of movement. Whereas most cars with rear-wheel steering max out at around 5 degrees of lock with the rear wheels, this Hummer can turn the wheels up to 10 degrees. Turn the wheel left or right in crab mode, and the Hummer moves diagonally down the street. If you use it for its intended purpose, crab mode is meant to help you navigate the Hummer through trails it might otherwise be too big to fit through using regular steering. In reality, we suspect most folks might use crab mode in the exact same fashion as GM did this past weekend: to impress people. And honestly, we canÂ’t blame them. It was a seriously cool sight to see. Crab mode in action: This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.
