    BMW X5 in CF saves 440lbs

    There's some merit to this carbon fiber stuff after all

    The BMW X5 4.6is features a unibody made out of CFRP. By using carbon fiber in the frame structure, BMW reduced the number of parts used in the X5. To furthermore reduce the overall weight, the on-off X5 comes with a CFRP-made hood, roof and rear hatch.
    According to BMW, only the doors remain made out of steel.
    Most of the savings are in the body structure and quoting a BMW specialist, the structure of the X5 is half of the weight of a regular first generation X5 model. The overall weight saving is 200 kilograms or 440 pounds.

    The BMW X5 with carbon fiber parts has never been shown to the public before and it has been driven for 40,000 kilometers as part of a testing and development program in the carbon-fiber engineering efforts.

    I really, really like this but just a one off from BMW? They have the production molds and pieces, why not sell it?

    Pretty sure this is a development mule to test the long term durability of structural carbon fiber. Needs desert testing, Arctic testing, bump testing, crash testing, etc etc.

    Shows they're thinking of using this in the future, working out the realities of it.

    I would not be surprised to see the first use of this in the F10 M5.

    No doubt, but would be cool if they offered it to us.

    They are building a plant specifically for carbon fiber production so they definitely are serious about it.

    I doubt the molds they have are real production molds, they are probably not fit to create 1000+ pieces.
    Some people live long, meaningful lives.

    Other people eat shit and die.

    I'm not racist, I hate everybody equally; especially fat people.

    Exactly, something like what TC Kline did for the Z4.

    The plant has actually been up and running for a while now-- the CSL roof was the first production piece from it.
