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.

Are you a BMW M4 GTS track car in disguise?

BMW is always happy to extract a little bit more gumption out of its M cars, just look at the latest 30th anniversary M5 or even the earlier CSL variants of the M3 for proof. Now, It looks like we might be getting the first glimpse of an even hotter M4, and it's wearing very interesting livery.
Our spies recently shot this M4 that could preview a future GTS version. It's all done up in MotoGP decals, but that might just be a ruse. This car sports a camouflaged lower air dam and rear wing, but those parts don't appear to be from an actual series safety car. The chin spoiler seems larger, and the rear wing is completely different. You can also spot an obvious Recaro logo on the driver's seat in one of the photos. Plus, the BMW emblem is removed at the back.
The disguised changes and odd choice of decals make this prototype incredibly weird. A BMW exec said at the beginning of the year that there were "no plans whatsoever to make a lighter, harder version just yet," of the M3 or M4, despite earlier rumors to the contrary. Check out the gallery to see what you think this is.

BMW M3, M4 let loose on the 'Ring

We just posted our first drive of the 2014 BMW 435i yesterday, but for those wanting even more power from this stylish coupe, help is on the way. From the sounds of it, BMW will be showing off a production-ready concept previewing the M4 next month at the Pebble Beach Concours d'Elegance, but until then, we have some new spy shots of the performance coupe being tested at the Nürburgring, along with its four-door counterpart, the M3.
Despite all the camouflage, it doesn't take much imagination to picture what both cars will look like, since we can clearly see the more aggressive front fascia and beefier brake setup. One interesting element we see on both cars is a double bubble roof that is almost certainly made from carbon fiber. Based on our report earlier, both the M4 Coupe and M3 Sedan are expected to debut at the 2014 Detroit Auto Show.
