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.

2014 Audi RS5 Cabriolet [w/video]

Brash Bruiser Loses Top, Gains Weight, Still Makes Friends
Everything we said after driving the RS5 coupe still rings true, even after Audi has gone and ripped off its metal roof, replaced it with a big cloth version, and tossed us the keys. The 2014 Audi RS5 Cabriolet is another bold, big-boned airmobile to make open-top lovers swoon. There is absolutely nothing revolutionary to speak of here versus its hardtop counterpart, frankly, but tear-assing through the southern French hills as the brilliant sun warmed us is plenty good reason to talk a lot about it anyway. And hey, it beats frigid January in Detroit, where the RS5 Convertible is shortly to receive its US introduction.
One issue that could corrupt things a bit is the convertible's added weight factor. It's one thing when an Audi TT removes its top and gains 176 pounds, or when a Porsche Cayman morphs into a Boxster and gains 66 pounds; the effect on dynamics will still be acceptable. But when it comes to a huge-roof coupe like the RS5, that gain in mass becomes 400-plus pounds in cabrio form, for a grand curb weight of 4,461 pounds. As a number attached to this size of a car that's also branded with an RS badge promising raciness, we admittedly fretted. Then we drove the Audi RS5 Cabriolet to cheer up.

Next Audi Q7 to debut with electric turbocharger?

For years, the concept of an electric turbocharger was essentially a joke sold on eBay to boost power in your slammed Civic, but in the last five years it has moved from an idea on a piece of paper to a feasible reality. Audi has already toyed with a showcase of the cutting-edge tech in road cars with the RS5 TDI concept. Now, reports suggest an electric turbo may make it to the streets as soon as next year in the next-gen Q7 (spy shot pictured above).
"I can confirm we are working on the development of the e-boost definitely," said Ulrich Weiss, Audi's diesel engine boss, to Australia-based Drive. He didn't give an exact timeframe but hinted at sometime next year, possibly in the Q7. He also suggested the chance of an RS-branded diesel model in the vein of the RS5 TDI concept on the horizon, as well.
This tech isn't entirely new for the folks in Ingolstadt. Audi's R18 endurance racer already uses such a system to capture waste heat from the engine, converting it to electric power to further power the hybrid car. The RS5 TDI concept employs a similar idea with a 3.0-liter, twin-turbocharged V6 with an electric supercharger to make up for the turbo lag. It's able to pump out 385 horsepower and 553 pound-feet of torque and allegedly sprint to 62 miles per hour in four seconds.
