Yeah the dash and what have you is plastic, but the metal content has probably only gone down (if it has at all) as steel makers can now get the same strength from thinner sheet metal.

Take a closer look at cars. Look at the Honda Element, for example. OR the Aztec. You'll find about 25% of the body is plastic. Honda will be producing a plastic/synthetic block for their new Si engine. Metal bumpers have been replaced by plastic. And a LOT of cars have the first 6-12 inches of the lower body cast in plastic now. Finally, at least one tire manufacturer is testing plastic tires.

Absolutely FALSE. Calculating expected costs of tech support IS and will ALWAYS be able to be done. Statistics are gathered from past calls and used to forecast future requirements. Info is purchased from other companies and from companies who specialize in forcasting costs. And if it can't be done to within a half a percent of being correct, beleive me, the error will lie in favor of the company, NOT the purchaser of the product.
A statment like yours only shows a certain amount of naiveté in business modeling.

Re: Support That Is Based Outside Of USA
Oh of course you try, I wasn't saying you don't. And of course you try to over estimate the costs, that's bleedin' obvious. But it can't be done with any pretence of accuracy. You can't predict all the problems that will occur AND the frequency of them. Especially in computers were you can test for every combination of hardware and software. Hell potential software conflicts alone is a vast field. If your claiming companys work out all the possible problems before hand I think it's you who's being naive.
Now if you have no idea what the problems will be and how serious they are how do you work out the cost of it? Unless you just take an (educated) guess at the number of phone calls and go from there. Then hire less staff just to be on the safe side. So its a stabbed at guess based on what happened before, nothing worked out about it.

Hey? plastic engine blocks? That just sounds wrong, as in deeply badly wrong. Thermal constraints alone kill that, before you even look at the other problems with that. Any proof of this, just because I'd be damn intersted in how they got round all the problems.
Impact testing is pushing the increased use of bodywork plastics, metal bodies are bad crumple zones, plastics will crumple properly. A massive simplification perhaps, but close enough.
That plastic coating of the lower body, are we talking about anti-corrosion treating or what? I'm not quite sure what your talking about.
Oh and those two examples mean bugger all to me as neither of those two cars are on sale in the UK, so I haven't seen them. Or I might have done, but with a different name. In either case I've no idea what they look like so really can't comment.

Re: Support That Is Based Outside Of USA
Plastic is cheap... and fairly strong... excellent for non-structural components such as the outer covering of a car, or the dashboard, or the sides of a car...

Re: Support That Is Based Outside Of USA
I saw a picture of that engine block 5 years ago. Being a toolmaker and working for a Division of GM at the time I can tell you this. While the engine block is a plastic composite, the moving parts are still metal (inserts, sleeves, bearings). The block is cooled by a unique 'heat-sink' system. There are 6-8 cooling lines running parallel to/on each cylinder. The plastic composite is forged using carbon based material that can withstand heat ranges of an operational engine. The 'casting' is machined as a metal block would be. The biggest problem they were having back then was warping, due to the torque load! AND that was five years ago. I have not seen any recent info on the progress, but I'm sure that with newer materials available, it's probably very close to becoming a reality.

Re: Support That Is Based Outside Of USA
Well you learn something every day, I was wondering how you'd do such a thing. As I understand what you said, and if I've got this right, their problem is actually still the heat.
That heat sink system is going to reduce the rigidity of the whole block significantly, if it works as I think it would. That reduction in structural rigidity would lead to defroming under torque, but if you remove the cooling then your going to melt the block.
Of course I could have completely misunderstood what you said. It has been know before

Re: Support That Is Based Outside Of USA
Dell is avoiding the mistake that Gateway made. Gateway service was located at their HQ in S. Dakota and the people were friendly and knowledgeable people who spoke in an understandable English. Gateway lost their #1 standing when people complained about their service taking to long to get to. Well now you can call and get service right away! There, people asked for it and they GOT IT!!! Be careful of what you ask for. You may get it!
I did not have to call Gateway very often, but when I did they took good care of me in a timely fashion (usually within 15 mins.). I understood everything they told me and they understood my problems without using flow charts.
Edit in red.

Re: Support That Is Based Outside Of USA
Actually Phil, the torque load would have deformed the block without the heat. It was a matter of design flaw. The material preformed well within it's specs, the actual stress of the crankshaft and the support of it were the biggest problems. A matter of New concept, Old design!

You must have not checked in in the last 15-20 years. Most cars these days, at least as sold in the US, have bodies consisting almost entirely of plastic and/or fiber glass. The frame and necessary parts of the engine are still steel, but that is about it. Its a way to not only make the car cheaper to build, but also to make it lighter, thus increasing gas mileage.
