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.

    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!

  • Analoggrotto Does anyone seriously listen to this?
  • Thomas Same here....but keep in mind that EVs are already much more efficient than ICE vehicles. They need to catch up in all the other areas you mentioned.
  • Analoggrotto It's great to see TTAC kicking up the best for their #1 corporate sponsor. Keep up the good work guys.
  • John66ny Title about self driving cars, linked podcast about headlight restoration. Some relationship?
  • Jeff JMII--If I did not get my Maverick my next choice was a Santa Cruz. They are different but then they are both compact pickups the only real compact pickups on the market. I am glad to hear that the Santa Cruz will have knobs and buttons on it for 2025 it would be good if they offered a hybrid as well. When I looked at both trucks it was less about brand loyalty and more about price, size, and features. I have owned 2 gm made trucks in the past and liked both but gm does not make a true compact truck and neither does Ram, Toyota, or Nissan. The Maverick was the only Ford product that I wanted. If I wanted a larger truck I would have kept either my 99 S-10 extended cab with a 2.2 I-4 5 speed or my 08 Isuzu I-370 4 x 4 with the 3.7 I-5, tow package, heated leather seats, and other niceties and it road like a luxury vehicle. I believe the demand is there for other manufacturers to make compact pickups. The proposed hybrid Toyota Stout would be a great truck. Subaru has experience making small trucks and they could make a very competitive compact truck and Subaru has a great all wheel drive system. Chevy has a great compact pickup offered in South America called the Montana which gm could make in North America and offered in the US and Canada. Ram has a great little compact truck offered in South America as well. Compact trucks are a great vehicle for those who want an open bed for hauling but what a smaller more affordable efficient practical vehicle.
