Do You Have The Stomach For Magnesium Trucks?

In July, the good old boy contingent was horrified to hear that Ford would contemplate building Ford tough trucks from a material considered good enough for beer cans: Aluminum. Now, they will be absolutely terrified by the news that GM wants to build trucks from a material known to treat heartburn: Magnesium.

It’s all for putting trucks on a weight-loss diet in order to meet fuel economy requirements. Magnesium is 75 percent lighter than steel and 33 percent lighter than aluminum, GM engineer Paul Krajewski told Reuters. Magnesium also costs three to four times as much as aluminum.

The stiff space-age metal is a bitch to work with. Usually, magnesium parts are formed by high pressure die casting. GM developed a way to stamp parts from magnesium sheet metal. Still, the process is slow and complicated: The sheet metal must be heated to 842 degrees Fahrenheit before stamping.

By 2020, magnesium will be able to take out 15 percent of the weight of a vehicle, leading to fuel savings of 9 percent to 12 percent, Reuters says. GM is just at the beginning. It’s first use for stamped sheet metal magnesium is a rear deck lid inner panel. Weight savings: 2.2 pounds. And you need to be very lucky to get a magnesium-enhanced truck. GM will make about 50 vehicles, which will be sold to consumers, using the magnesium sheet process in the fourth quarter, but nobody is telling which models will be graced with the space-age parts.

    How much lighter is the Tacoma's composite bed over a steel bed? Ya got to start somewhere.

    Ford, GM, Chrysler, Diamler and Honda have been utilizing die cast magnesium products from Meridian (supplier) for a while, now. There aren't many other Mg die cast players out there due to the stringent process and volatile raw material costs. That is a niche won by the leanest player and it's a relatively young concept. Intriguing article. Thank you for the brain food!

  • Jonathan IMO the hatchback sedans like the Audi A5 Sportback, the Kia Stinger, and the already gone Buick Sportback are the answer to SUVs. The A5 and the AWD version of the Stinger being the better overall option IMO. I drive the A5, and love the depth and size of the trunk space as well as the low lift over. I've yet to find anything I need to carry that I can't, although I admit I don't carry things like drywall, building materials, etc. However, add in the fun to drive handling characteristics, there's almost no SUV that compares.
  • C-b65792653 I'm starting to wonder about Elon....again!!I see a parallel with Henry Ford who was the wealthiest industrialist at one time. Henry went off on a tangent with the peace ship for WWI, Ford TriMotor, invasive social engineering, etc. Once the economy went bad, the focus fell back to cars. Elon became one of the wealthiest industrialist in the 21st century. Then he went off with the space venture, boring holes in the ground venture, "X" (formerly Twitter), etc, etc, etc. Once Tesla hit a plateau and he realized his EVs were a commodity, he too is focused on his primary money making machine. Yet, I feel Elon is over reacting. Down sizing is the nature of the beast in the auto industry; you can't get around that. But hacking the Super Charger division is like cutting off your own leg. IIRC, GM and Ford were scheduled to sign on to the exclusive Tesla charging format. That would have doubled or tripled his charging opportunity. I wonder what those at the Renaissance Center and the Glass House are thinking now. As alluded to, there's blood in the water and other charging companies will fill the void. I believe other nations have standardized EV charging (EU & China). Elon had the chance to have his charging system as the default in North America. Now, he's dropped the ball. He's lost considerable influence on what the standardized format will eventually be. Tremendous opportunity lost. 🚗🚗🚗
  • Tassos I never used winter tires, and the last two decades I am driving almost only rear wheel drive cars, half of them in MI. I always bought all season tires for them, but the diff between touring and non touring flavors never came up. Does it make even the smallest bit of difference? (I will not read the lengthy article because I believe it does not).
