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.

Audi A3 Clubsport Quattro concept bringing its 525 horses to W?rthersee

It's almost late May, and you know what that means: the last of the snow has melted, the Stanley Cup playoffs are in full swing, the flowers are blooming, and the performance-car faithful are descending on Wörthersee in Austria for the annual GTI-Treffen.
Not only is the Wörthersee Tour (as the automaker calls it) a chance for enthusiasts to show off their rides, it's also a prime opportunity for the Volkswagen Group to show some of its most dedicated customers what it can do. Past meets have given us such notables as the Audi A1 Clubsport Quattro, Volkswagen GTI W12-650 and Skoda Fabia RS 2000 Roadster, to name just a few. And now Audi has emerged as the first VW Group brand to reveal what it has in store.
It's called the A3 Clubsport Quattro, and seems to offer a pretty clear indication of what we should expect of the next RS3. The concept is based on the S3 sedan, but swaps out its 2.0-liter turbo four for a retuned version of Audi's sweet 2.5-liter turbocharged inline-five, retuned to produce a massive 525 horsepower and 442 pound-feet of torque.

Audi exec denies plans for turbo R8

Sometimes smoke doesn't lead to fire. Rumors indicated Audi might drop a turbocharged engine into the latest R8, but now a top executive is throwing a bucket of cold water onto the burning speculation. "The performance potential of this current engine means we don't need to even look at turbocharging at this point," Jurgen Konigstedt, Audi development boss for V6, V8, and V10 engines, said to CarAdvice. He also said sticking with natural aspiration offered a better sound and sharper throttle response than going with forced induction. "There is less emotion with a turbocharged engine," he said. Konigstedt admitted there was a serious discussion about turbocharging the R8. The argument just didn't win out. "If we feel that people absolutely want a turbocharged engine, then we will have to consider it," he said to CarAdvice. Audi just launched a new generation of the supercar. The 2017 R8's 5.2-liter V10 will be available in two tunes: with 540 horsepower in the standard coupe or 610 hp in the Plus. Rumors have persisted about a smaller, forced induction powerplant at the bottom of the range. Some reports suggested a twin-turbo V6 behind the driver, but others said the electrically supercharged 2.5-liter inline five was a candidate. The reason for the entry-level addition was tied to lowering the taxes on the R8 in markets like China. Related Video:
