PVC boats are great, PVC car chassis and bodies coming next?

Automakers would like to just cast their car chassis and bodies instead of stamping and welding sheet metal.
Aluminum is finding some use for the same reason.

So Are PVC molded cars the future?
Despite higher initial material costs compared to steel, they would be offset by less tooling and higher flexibility for model changes.

Using contrarian principles, GM is refusing to use PVC in their cars, although only in interiors.
GM and most US automakers are known for their bad decisions so it makes sense that if they refuse something then that's a good thing and they will try to catch up when it's too late ...again.

Of course PVC pollution can be overcome.

Loads going through a boat haul isn't quite the same as that of a car chassis...Plastic/composite cars exists, but not in the way you think. The forged composite stuff that Lamborghini is experimenting might find its way down in cost and could be a viable material to replace some bulk section in the vehicle....

pollution if fire is NOT contrarian really :(
It can also self-fuel a fire at lower temperatures - so higher risk of conflagration.

"of course PVC pollution can be overcome"
Really?
Care to suggest how ? At an affordable cost and with reduced resources compared to alternatives ?

PVC works for boats because, a) it's only used on small boats, b) no real "point loads" in boats as with suspension points on cars c) boats don't run into things regularly :) d) boats float and PVC easy to make chambers ... could go on.

My dad owns a boat and we've seen other boaters and you'd be surprised. The lack of brakes is what gets most people

ah, I should have added "at speed".
and "regularly" still holds, I've crewed yachts and whilst you get rubs and bumps, when was the last time you saw a T-bone or head-on ?
( OK, aggressive racing leads some skippers to execute turns and spear a competitor, but in general not happening )

Lol never but jet-skiers have almost gotten pancaked a few times!

Several automakers have utilized PVC for major body panels, and nearly all now use it for bumper covers and trim. But that's all it's good for.

Well Automotive Industry are fast growing specially with deals to innovations formulation. No one can tell with the movement of PVC molded cars in the future.
