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 this Audi RS6 go 208 mph... on ice

In and effort to promote the high-speed grip of its new Hakkapeliitta 8 winter tire, Nokian threw a set of its new rubber on a race-prepped Audi RS6 and got moving - very, very quickly. In fact, on March 9 on top of the very frozen Gulf of Bothinia near Oulu, Finland, Nokian's test driver Janne Laitinen set a new world record for the fastest speed recorded driving on ice. If you'll recall, this isn't the first time that Audi and Nokian have played this game, either.
Using the guidelines set forth by the Guinness Book of World Records for such things, Laitinen averaged 208.602 miles per hour (335.713 kilometers per hour) over the course of two runs on natural, untreated ice. Another constraint is that the ice speed record must be done using commercial available tires, which is obviously great PR for the new Hakkapeliitas. The press release doesn't make any mention of how the RS6 was prepared to reach such high velocities, but the images of the car make it clear that this is no stock machine. Scroll on below to see the impressive video evidence of the Audi's record run.

Audi welcomes Porsche back to Le Mans like any sibling would

Ah, sibling rivalry. It really is a beautiful thing. It's even more beautiful when said siblings are automakers with very, very well-known racing histories. That's how you get videos like this, which is Audi's way of welcoming Porsche back to the top flight of Le Mans racing.
Yes, Audi has taken its R18 E-Tron Quattro back onto public roads, wowing schoolboys and scaring farmers (who appear to be riding classic Porsche tractors), as it travels from Ingolstadt to Zuffenhausen, just to taunt its corporate frenemy.
Take a look below for a video to see just what that teasing looks like.
