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.

2013 Audi Allroad

Reincarnated With A Smaller And Less Passionate Soul
Mention the name "Allroad" to most automotive enthusiasts, and it's likely to conjure up images of the Audi A6 Allroad Quattro, first introduced in 1999. That car-like alternative to a sport utility vehicle was based on the German automaker's A6 Avant wagon. But unlike its luxurious road-going sibling, the Allroad was an on- and off-road variant fitted with an advanced height-adjustable air suspension for additional ground clearance, rugged tires on oversized wheels to improve off-pavement grip and unpainted flared fenders and bumpers to protect it from rugged use. That original A6 Allroad arrived with Audi's powerful twin-turbo 2.7-liter V6, more to offset its increased weight than to boost performance, and was eventually offered with a 4.2-liter V8 before it was discontinued in 2005.
Fast forward eight years, and Audi has introduced its replacement - now based on the smaller A4 Avant wagon.

Audi, Porsche ensnared in new Volkswagen cheating allegations

The scope of the Volkswagen emissions cheating scandal that has enveloped the global automaker for the past six weeks widened Monday. Now, some of the automaker's premium brands are further ensnared in the mess. Officials with the Environmental Protection Agency issued a second notice of violations Monday, accusing Volkswagen of violating the Clean Air Act by using defeat devices that circumvent emissions testing on diesel versions of certain vehicles equipped with 3.0-liter engines. Roughly 10,000 vehicles in the United States contain the illegal software, the EPA alleges. That's a far smaller number than the 482,000 vehicles affected by the first instances of cheating, which Volkswagen confessed to in September. But this latest violation alleges the cheating occurred broadly through the Volkswagen empire and includes vehicles from the Porsche and Audi brands. Audi had one model, the A3, involved in the first round of announced violations. But the brand, which has enjoyed skyrocketing sales in the US in recent years, is more extensively involved in violations announced Monday. The 2016 Audi A6 Quattro, A7 Quattro, A8, A8L and Q5 are among the cars which contain the illegal software, which permits the cars to emit nitrogen oxide at up to nine times the allowable thresholds set in the Clean Air Act, according to the EPA. The 2015 Porsche Cayenne and '14 Volkswagen Toureg SUV are also affected. "There is clear evidence of additional violations and it's important to put Volkswagen on notice and to inform the public." - Janet McCabe. "Audi, which has been on a roll in terms of sales, reputation and image of late, now is being drawn deeper into the quagmire," said Michelle Krebs, senior analyst for Autotrader. "Previously, only the low-volume A3 was under scrutiny, but now Audi's core models are under fire." Audi officials did not respond to a request for comment Monday. In a written statement issued late Monday afternoon, a Porsche spokesperson said, "We are surprised to learn this information. Until this notice, all our information was that the Porsche Cayenne Diesel is fully compliant." Porsche said it would cooperate with authorities.
