nytimes.com article about aluminum frames
http://www.nytimes.com/2006/10/22/au...ef=automobiles
it's interesting to see who IS NOT mentioned in the article, that marque that is closest to our hearts, the one that brought most of us together. yeah, i know about the z8 --i also know about the frame problems that the z8 has been shown to have. i wonder when BMW is going to start rolling out aluminum in their frames (and Porsche, too). BMW has insisted that they won't go up in displacement for fuel economy reasons so their power will be, in the future, come from turbos --but with their curb weights this high, someone in Munich is going to have to implement serious weight savings measures. and i'm not just talking about Saturn-esque SMC body fenders that are found on the 6 series.

but it's true that the e60 uses a lot of aluminum.

and i rue the day that i will have to have my C6 frame worked on by a dealer network ill-prepared to deal with aluminum. but that will never stop me from buying the car that i would want. for example, i'd be thrilled if GM decided to use aluminum frames for the CTS genII cars instead of steel used in the Monaro/G8/Camaro to improve its power to weight ratio. i'd pay the extra money for the superior car. Porsche fights weight pretty well, but you can already see that the GT3 is above 3000lbs, the 997 S is close to 3300pounds and the 997TT is more of a porker than the 996tt was/is. in my opinion, their options are locked in because of the rear engine placement and the fact that it will not accept an engine larger than 4.0litres. that's why i think more and more the next 911 will be "rear mid-engined". if Porsche won't use aluminum, they're going to have to use displacement. no way around it. and BMW can keep pushing turbos, but the high curb weights will always tax the smaller displacement engines. the 335i, for example, will be great for commuting. but heat soak will dial back the power significantly during college idiot-type driving. and think about tracking that car? think again. little teensy brakes, plus retarded ignition timing due to heat soak and you have a bloated car that will get passed by lighter cars with superior brakes.

But as more and more makers put Al into frames/chassis, it will force shops to make the switch. Otherwise their market will shrink. Times change.

My wife and I were shopping for new garage doors the other day - I picked up a cross section of one made of wood, then steel, then aluminum, it's really stunning how much lighter the identical piece made of aluminum felt.
