So? The Quickstep nanotube composite and joining process does not use high pressures or temperatures. Net shapes formed.

Steel is recyclable carbon fiber can be burned if the fumes from the glues aren't too toxic.

Excellent product. Ordinary structural steel has a tensile strength of 36 K (in the English units I am more familiar with), but this top end stuff converts out to 232 K if I did the operation correctly, That's simply amazing!
On the other hand, the objective is to shave a hundred pounds off a car., so I'm wondering why anyone should bother, now that pretty much each person driving or riding in the a car is overweight by at least that much?
Ironic.

"No infrastructure changes" makes it a no-brainer - higher strength should mean thinner / lighter / better fuel economy.

I agree with Takis about the passengers being the cheapest place to drop weight. I was talking with a guy who was proud to have spent $15,000 in aftermarket equipment to reduce the weight of his motorcycle by 30kg. I pointed out that if he ate less he'd actually save money and easily drop 30kg. But he preferred to spend the money, enough that he could have bought a second track only bike.

Good news for the consumer owned rooftop solar PV industry. The batteries can be smaller and the electric vehicle range can be extended. Those owning these rooftop units will pay a less than zero fuel cost (via free energy from sunshine) over the lifetime of the vehicle.

More bull from the 'business as usual' auto makers. They don't want to make vehicles out of anything but steel because they are part of the steel fabrication industry, not because steel is the best material to use. For instance, polycarbonates are a third of the weight and 10X AS STRONG. In conditions where a steel vehicle will crush, a polycarbonate vehicle will be more inclined to bounce with the occupants securely strapped inside, like riding inside a crash helmet and, of course, that's not the only material available. Check out new entry manufacturers who are not tied to steel like Tesla. They wouldn't use steel in a fit because it's an inferior material for this use. If the old guard auto makers, who really only want to sell us steel vehicles with internal combustion engines, don't change their ways they are in danger of being marginalised.

There are people that think loosing weight is easy; they have never tried.

Steel ages far better than high strength aluminum and is far cheaper than either aluminum or composite materials.

@apprenticeearthwiz
the 'crushing' of steel is exactly the reason why it is more suited to passenger vehicles than polymers. When steel crushes it removes energy from the impact that is not then able to pass to the occupants.
Crash a carbonfibre car and see what happens to you. i.e. the death of a test driver in the Lexus LFA.
