GM plays catchup in the aluminum game

We’ve all heard about the 2015 Ford F-150 and the fact that its aluminum diet allowed it to lose 700 pounds. While the ladder frame of the all-new F-150 is still constructed of high-strength steel, 95 percent of its body structure made of “high-strength, military-grade, aluminum alloys” according to Ford.
 
So Ford has gone to aluminum to reduce weight and thus improve fuel economy. Chrysler has gone a completely different route by providing a new V6 diesel engine for the half-ton Ram 1500. So that leaves the industry looking to General Motors to provide a counterpunch in the full-size pickup fuel efficiency wars.
 
We are now learning that General Motors will take the Ford approach by using aluminum for the body of its next generation Chevrolet Silverado and GMC Sierra full-size trucks. According to The Wall Street Journal, GM’s hand has been forced by increasingly stringent fuel economy standards (and of course market pressure from rivals).

According to the WSJ report, GM is partnering with both Alcoa and Novelis to supply aluminum sheets for its next generation trucks. As we reported earlier this month, Ford has already inked a deal with Novelis to supply aluminum sheets for its F-150.
 
“There’s isn’t an automotive manufacturer that makes vehicles in North America that we’re not talking to,” said Tom Boney, head of North American automotive business for Novelis, in an interview with The Detroit News. “Our customers will be making announcements fairly regularly over the next six years that will transform the automobile industry.”
 
GM last redesigned the Silverado/Sierra in 2013 for the 2014 model year.

especially after having aluminum on a car myself.

Just out of curiosity, what aluminum car did you own? I did not know there were any mainstream cars (maybe you had a specialty or custom car) that were made out of aluminum.

I do not have alot of experience with aluminum (especially the grade that Ford is using), so am wondering what kinds of issues to look out for. Not planning on buying one of these, just interested.

Best one ever was that last model RX7, what a car. Aluminum body light weight and a turbo rotary engine for extreme weight to HP. Oh yeah, if I were looking for the ultimate classic sports car down the road I think I would grab one of these.

Thanks, I had no idea. I never had (or really wanted) an rx7, so I didn't know.

The scariest/most fun I ever had in a car was a third 'gen RX-7 Turbo. Holy crap, what a blast.

Finding one not ragged to hell at this point, and keeping one running, is a whole different story :(

The FD RX-7 did not have an aluminum body. I think you're recalling the NSX.

The FD RX-7 was extremely lightweight, but not due to aluminum.

Lots of them... my Lincoln LS has aluminum hood, trunk and fenders. That was 15 years ago.

That is interesting that Ford is making a big deal out of it if they already had production cars with it.

Making a few bolt on body panels out of aluminum is not the same as constructing the entire body structure out of aluminum.

Yeah, parts of the unibody, ALL the suspension and steering components were also alum.

Ford also owned Jaguar at the time when it was one of the first cars with a full aluminum body.

From what I can tell Jaguar sold about 20,000 X350's in 2003 which was the first year for the aluminum body. Last year Ford sold about 763,000 F150 pick up trucks. Whatever the scale of the process used for the Jag, I get the feeling it's a whole new ball game for the F150.

Note that Semi-Trucks and trailers are often skinned in Aluminum, and they can be ordered with Aluminum frame rails as well and have been for more than 30 years.

Indeed, Ford has been doing this quite a while.

The 2014 corvette body is made out of aluminum, but not the panels as far as I know.

The Corvettes have had aluminum frames for years. Their bodies are fiberglass.

Audi A8 employs an aluminium frame and body since about 2002
