Arrow BMW leaks first-gen X5 made of carbon fiber!

BMW leaks first-gen X5 made of carbon fiber!

* 06.07.2010


BMW has been making some headlines over the past few months with its commitment to carbon fiber construction, opening a joint-venture production facility in Washington State and teasing the upcoming Megacity EV as the first mass-produced carbon fiber vehicle. But there's always a back story to the headlines.

As you might have guessed, BMW has been toying around with the lightweight construction material for some time, seeing just how far it could push the envelop and what practical applications it could have. In this case, it turns out that, back around 2003, the Bavarian automaker re-constructed a first-gen X5 sport-ute with a carbon fiber reinforced plastic (CFRP) unibody. Every panel on the X5 was replaced with CFRP, save the doors which retained their conventional steel construction. The result was a weight savings of 440 pounds, without according to BMW sacrificing structural rigidity and crash-worthiness.

Of course the carbon X5 was never put into production, but it reportedly underwent some 40,000 kilometers (25,000 miles) of testing, and the knowledge gleaned will surely find its way into BMW's production vehicles in the future.

makes me wonder why they didn't do it in their E46 M3 or something that deserves the CF instead of an SAV lol.

Crash repair would prevent a volume car like that from being produced. A low volume Ferrari or Lambo could be sent back to the factory for repair if needed. Your corner bodt shop is not equipted to handle carbon momcoque repair. No doubt the day it coming for lighter and stronger materials. Without factory support it will never happen.
