Researchers halfway to cutting carbon fiber costs by 90%

Carbon fiber has been utilized for decades to build racecars, as a means to cut weight while maintaining strength. But until recently, the space-age material has been largely absent from the street on anything but supercars because of the expense to use it. Recently, BMW signaled a major shift in that trend when it starting using carbon fiber reinforced plastic panels on the i3 and i8. This relatively small scale start might be just the beginning; the German company believes that a breakthrough to inexpensively manufacture the lightweight stuff is just on the horizon.
MAI Carbon Cluster Management GmbH counts BMW, Audi, Airbus, the German government and many other organizations as supporters, and it's researching how to make carbon fiber cheaper to produce, according to Automotive News Europe. The company thinks it can reduce costs by 90 percent in the near future. "We've certainly reached a halfway point on our cost-cutting target for suitable carbon-fiber parts," said project head Klaus Drechsler to Automotive News Europe.
Unfortunately, it isn't entirely clear just what MAI Carbon is doing to make such a huge leap possible. However, a recent post on the company's website talks about a new form a carbon fiber using a thermoplastic matrix that could be cured in less than three minutes. That's compared to about 90 minutes in the traditional process with an autoclave.

Watch Audi R8 give Birth to RS3

In the cold light of reality, it's a fairly dubious proposition to suggest that the Audi RS3 Sportback shares much of a mechanical relationship with an R8. One of them is supercar with a snorting V10 and lithe body, while the other is a still-capable hot hatch with roots lower in the brand's range. However, marketing doesn't necessarily have to sell real life, and Audi's advertisers are nailing the emotional pull of these two models in a spot called Birth. With dramatic music and a sci-fi aesthetic, the R8's V10 roars as the supercar stretches and deforms, and eventually the hot hatch gets plucked from its metallic loins. Regardless of how closely these two models are related, this commercial looks and sounds fantastic. With the US rumored to get the RS3 in sedan form at some point, hopefully we get a tweaked version of this ad.

Next Audi R8 seen and heard in this spy video

A few weeks ago, our clandestine spy photographers brought home the first good look at the next-generation Audi R8. We were all pretty stoked.
Seemingly following the game plan of the recently shown Audi TT, the next R8 looks to be an evolutionary update on a supercar form that pretty much everyone loves.
Today, the same shooters that snapped the car in stills have delivered some pretty compelling moving pictures of the thing. Captured both in some less-than-inspiring around-town traffic situations and out on the Nürburgring, the video delivers our first taste of the new R8's auditory splendor. Well... a taste of it, anyway.
