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.

24 Hours of Le Mans an on-and-off love affair

There was little usual about this year's 24 Hours of Le Mans - intermittent rain in the weeks before the race meant cars didn't get on track as much as they wanted, and intermittent rain during the race meant cars went off track a lot more than they wanted. The race started with a wet track, and one of the records broken because of the random downpours was the number of times the safety car led the field - 11 times this year - although the record of two hours and 53 minutes of lapping behind the safety car, set in 2011, was not eclipsed.
None of that served to dampen the action. With little more than an hour left in the race there were cars still only a few seconds apart fighting for position, leads still changing because of pit stops and everyone drafting anyone they could.
Things didn't go the usual way up front, either - well, not exactly...

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.
