Strength obviously depends on the manufacturing goals, but with things like bike forks and rims, the failure strength tends to be magnitudes better than aluminum while weighing a good bit less. Given equal weight, you'd likely have three to four times the strength, sacrifice to say 30% less weight and you'd likely still retain 1.5-2x the strength of aluminum. I'm not saying I want to be the first one to curb one though! |

Pretty Lightweights. I left road wheels out of the discussion simply because of heat issues with carbon clinchers, which of course will be a non issue once road discs become more standard (and SRAM's don't explode).

It could be interesting. The things that scare me though are how they reinforce/jacket the lug interface, what mounting tires is like and if they can be repaired. I can't see them being any cheaper than a good set of forged wheels, but for dedicated track wheels, combined with the weight savings of carbon ceramic brakes, you could easily shave quite a bit of rotating mass off of each corner.

This is really interesting. If you can put the carbon fibre "mash" into a plastic moulding machine, the more i3 and i8 models they produce perhaps the less expensive CFRP parts like the steering wheel mentioned above could become! These raw materials are made in Washington State too!

If price of a set will be 4 times the price of normal rims, and they will be fragile like a glass, then I will pass.
I don't see a point in these wheels apart from racing on the track for a light weight oriented and focused car, If I want to get 100 pounds off of my car, I would just empty out my trunk, and all the junk. |

BMW Efficient Dynamics celebrates its seventh anniversary with a further look into how lightweight engineering becomes an integral feature of Efficient Dynamics previewing the next generation of BMW models and the many new innovative features they will take to be lighter than today's models.
The journey starts here...

I'm impressed that BMW decided to take a stab at it...whether BMW's version will be "cost effective" or "good value" remains to be seen. It might go the way of carbon ceramic brakes for a good while in regards to either its appeal for looks and/or actual improvement in performance/safety, but who doesn't like unpainted CFRP wheels they can abuse on the track or just to show off. Let's get the "go green activists" and the gov't safety regulators to promote this so that everyone else will have to get on the CF wheel bandwagon, I hope that they ban cheap steel and heavy wheels ASAP.
