Why not use Aluminum?

Is it too cost prohibitive to use aluminum to fabricate body panels? It seems the benefits to using Aluminum would be obvious in that it is light weight and is resistant to corrosion and inturn because it is light-weight gas mileage would improve. It seems even with galvanized steel sheet metal rust and corrosion are inevitable. The sheet metal these days is so thin that even surface rust can perforate the panels. Has there ever been a car body made from Aluminum?

I believe the Dalorian (sp?) was all aluminum (aka the "Back to the Future" car). The Acura NSX also has an all alum body for the most part. I'm sure there are more cars out there, but no doubt all these cars will be at a premium because of the cost of working and using aluminum.
 
I am not certain, but I believe aluminum may be very difficult to paint. I looked into re-painting an old aluminum boat one time, and from what I remember, it would have been a difficult process using chemicals and paints that were environmentally unfriendly and unsafe from a health standpoint.

It sounded like enough of a nuisance that I didn't go through with it.
 
A8 is aluminum bodied, and I am pretty sure that a lot of the super cars (or italian sports cars) are aluiminum

super cars would stay away from aluminum, they would use carbon fiber composite instead.

Actually the Ferrari F430 is an aluminum frame with aluminum body panels. From www.edmunds.com "Thanks to an aluminum space frame draped with aluminum body panels, the F430 weighs in at a relatively svelte 3,200 pounds"
 
The Audi A8 is not aluminum...the space frame is designed in part with Alcoa as is most everyother aluminum space frame in the automotive market.

I would take this as saying the A8 is aluminum...I am pretty sure I have read this multiple times in Autoweek and magazines like that. Again, from edmunds.com "In addition to its all-aluminum construction"

The Delorean was actually a stainless steal car


Ah. I stand corrected.

I also remember something about it hiding cocaine in the Delorean tires. Something I remember from the news as a kid.

Thats how they came up with those commercials right? Fry an egg on the stainless Delorean...this is your brain the drugs that are hidden in your tires
 
But with the technology today and treated meatl i don't think things rust like they used to. The old Toyotas used to be really prone to rusting out here in Wisconsin "the road salt belt" of the nation.

Are todays Toyotas anymore prone to rust than any other mfg. ?

Alum. wont rust but will still corrode and get eaten away actually faster then metal. Like if you live where I live with all the road salt a chip in the paint will start the same process. Granted it will not rot through like metal but will spread underneath the paint and cause havoc.

Re paint , materials , ect... it would not be cost effective at this point. Our 4R's would probablt cost $ 50,000.00 - $ 60,000.00
 
I think the cocaine tires was an add on option! kind of like a run flat, if it got punctured...the cocain would come out already in lines...:biggrin2:

I take it back...the newest version does have full aluminum construction. Previous models did not.

are we talking about the frame or body panels? im lost.
not all super cars have all aluminum.

Well in regards to the Audi A8...we were talking about the entire car. Most supercars these days are a mix of alum, carbon fiber, kevlar and maybe if your lucky, Iconel.

They also had a problem with aligning the front end correctly as the cars always wanted to follow the white lines on the road. :D
