Stupid GM, why the hell didn't they remember to come to NASIOC first to make sure this wasn't a horrible idea?

Great idea and alternative to carbon, plastic, or fiberglass
Based on the Viper community, I have a feeling that a lot of GM body panels are going to be melted accidentally in the future. |

I can't remember where I read it. But the article talks about how car companies are trying to make lighter cars, but it get's cancelled out because americans are getting fatter. we are nation of fatties
Also, not too keen on magnesium. They burn hot as hell. Their burning temp is off the chart. I'm sure the GM knows properties of magnesium. Hopefully, it will turn out well. If not, there will be crap load of people ready to sue. |

If only GM had the existing technology to build vehicles with plastic or fibreglass bodies.

Why not stop pumping weight into the damn thing in the first place? Make your engineers work and work with them.

Is it 100% magnesium or is it some hybrid mix like with aluminum or something?

Mag also hates oxygen. And I do not think that was water causing that explosion of white light.
Flames will cause mag to ignite and explode. |

Once mag is ignited it will burn and keep burning. Road flairs are basically magnesium. Light a flair and through it in water, it will get brighter and keep going. The water is what caused the accelerated burning. The burning will separate the oxygen from the hydrogen and they will both burn.
Never put of a mag fire with water. Any firemen want to chime in? Peace, Greg |

GM knows what they are doing and going green at the same time.
A friend of friend told me that they are going to coat the magnesium with a white phosphorus impregnated shellac... . |

It's all the federal safety requirements. Crumple zones, ABS required, DSC required, traction control required, air bags required. Add on six speed auto trans, leather, coffee maker, panoramic sunroof, 18 cup holders, quad DVD entertainment systems... We are just now getting back to MPG numbers we had in the early to mid 80s in gas burners. My roommate in college got 44mpg with his '85 Honda CRX. I wouldn't want to get hit by anything in that little tub, but it got good mileage and was fun to drive. My '87 Honda Prelude, in college, got mid-30s mpg, I got as high as 37mpg on a highway run to FL. No ABS, air bags, etc. It was quick and fun to drive because there was nothing to it (2300lbs). If I could find another 1st or 2nd gen in decent condition, I'd probably snatch it up for a DD when I'm not hauling the kids (no room for car seats + >6' driver ). |

If this goes into production, it'll be interesting to see insurance rates for those vehicles. I would imagine this would add to the cost of a wreck or simple fender bender, depending on how much of the car is mag. I bet there will be cheap, steel non-oem panels for these cars being made just like every other car. Might behoove the owner to make sure they're getting genuine oem mag replacement panels.

Magnesium is lighter and therefore will cost less to ship back and forth to China.
