Koenigsegg Make first hollow carbon fiber wheel
 
2 Attachment(s)
The 2013 Agera R features the world's first hollow, one piece, super light carbon fiber wheel, using a proprietary method developed by Koenigsegg named Aircore Technology. The Aircore wheels save close to 20kg in unsprung mass, while providing great integrity and safety. The only metal part in the wheel is the tire valve - the rest is all one piece hollow carbon.

That's pretty interesting, wish there was more info on the wheel.

A company called 360 has been making CF wheels or some time...

Technological advance is unnecessary? Excessive, yes. Unnecessary? No.

That's what I've been looking for a while (more hollow wheel info) to show my shop and see what they think but I keep getting that same little info then about the car.

Hollow CF is nothing new. Epoxy resin (not polyester resin), polystyrene core. Make part. Dissolve out core with acetone. Done.

All right, but outside of the occasional motorcycle wheel, has there been any other application of hollow CF wheels? The fact that Koenigsegg is confident enough to put these onto a production car says something...that the technology is getting to a usable point while being safe. I bet it's just a matter of cost now.

That's all that it ever has been for years. Koenigsegg is a niche builder with huge margins so the CF wheels isn't really earth-shattering news. Tech is mature but still expensive due to the amount of labour involved, that's all.

Wow. CF being used for all types of interesting ways. I want more info about the wheel though.

I know CF is light & strong and all... but is it strong enough to take the all the beating?

The first? hardly.

The first OEM hollow spoke cfrp wheels, sure. Formula SAE teams have been making them since ~2005.

That all depends on how large of a safety factor the engineers used. But , yes, cfrp wheels can be ridiculously tough/strong if they are designed to be.
