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.

2016 Audi RS7 Performance is an LA beauty in blue

The whole point of the new 2016 Audi RS7 Performance is directly in its name, and the Four Rings now claims 605 horsepower from its 4.0-liter twin turbo V8. For those keeping track of big-brother bragging rights, Audi claims 560 hp from the standard RS7. Plus, the engine's torque can jump from 516 pound-feet to 553 lb-ft during the temporary overboost function. An eight-speed automatic gearbox still sends power to the front and rear through the Quattro all-wheel drive system. The results of all these upgrades are a sprint to 60 miles per hour in 3.6 seconds and a top speed of 190 mph. The RS7 Performance is about more than just power; Audi also fits carbon ceramic brakes and an RS Sport Suspension with Dynamic Ride Control. The exterior also sees some minor tweaks that include a restyled rear diffuser, new 21-inch wheels, black tailpipes, and a gloss black grille. RS sport seats come standard inside. The RS7 Performance arrives at Audi dealers in December and prices start at $129,925 (after $925 for destination). Get a good look at this very quick, fastback sedan in the gallery above.

MotorWeek revisits Audi's iconic Quattro

The Subaru WRX, Mitsubishi Lancer Evolution and just about every other all-wheel-drive performance car owes something to the legendary Audi Quattro, a model that was far more successful on the motorsports scene than it was in the showroom. Despite its modest sales, the UrQuattro still looms large in automotive lore, and indeed, in Audi's own sense of self. Considering the brand's semi-regular flirtation with the idea of a reborn Quattro, MotorWeek must have figured it'd be a good idea to revisit the original by digging up this archival review.
While time has the ability to cover up the warts of iconic automobiles, it should be noted that Motor Week host John Davis had more than a few critiques for the all-wheel-drive, turbocharged coupe.
Davis calls the Quattro's slalom handling "a disappointment," citing the overpowered engine and slow steering, and he had some unkind words for the brakes, as well. For our part, we're kind of wowed by the amount of ship-like body motion during testing, yet that sort of bobbing was certainly par for the course back in the early '80s.
