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 R8 E-Tron back on production map thanks to new battery tech?

Contrary to our October 2012 report, it appears Audi's R8 E-Tron program is back on track, if a report from Australia is to be believed. Drive is reporting that the German brand has changed its mind and won't be sacking the program, despite previously stated concerns about the quality and price of batteries for the R8-based EV.
We last saw the R8 E-Tron prototype in the snows of northern Europe, although footage of the car has been non-existent since that wintry test. This new report claims that a small number of R8 E-Trons will see production, which gels with what we heard back in 2012 and supposed earlier this year. Apparently, some new sort of lithium-ion battery technology has allowed for a drastic increase in range, with rumors of the original 130 miles going up to around 250. According to Drive, this makes the project feasible again.
"Our engineers and technicians are further developing the car and its electric drive system. The range has grown significantly, allowing the potential for a small-scale production," an unnamed, but high-ranking Audi employee told the Aussies.

MTM Audi RS6 Clubsport might be overkill for grocery shopping

As automotive journalists, we're biologically wired to love station wagons. We really don't have a choice. And while we prefer brown, diesel-powered, manual-transmissioned long-roofs, we suppose a 750-horsepower Audi RS6 Avant would be just dandy. This is the MTM RS6 Clubsport, and as we mentioned, it's very powerful. That's thanks to a modified version of Audi's critically acclaimed 4.0-liter, twin-turbocharged V8. While 750 hp out of just 4.0 liters is impressive, 697 pound-feet of torque is an equally big accomplishment. And if that's not enough, MTM has managed to shave nearly 200 pounds of body fat from the big wagon. Needless to say, it's very, very fast. MTM has displayed a degree of aesthetic restraint, eschewing the gaudy body kit favored by some other tuners and simply opting for a questionable paint job. The 21-inch wheels look good, although with the smattering of rubber around them, we wouldn't bet on a comfortable ride. As for the cabin, well, MTM got a bit out of hand. It's very, very orange. The seats are essentially carbon-fiber shells lined with bits of orange, leather-wrapped padding here and there. Orange, quilted-leather in the door panels, center armrest and on cushions on the side of the center console – a nice touch we wish more automakers would add to their performance cars – contrasts nicely with the black plastics and carbon fiber found on the rest of the dash and center console. That said, we aren't crazy about space for passengers, thanks to the large cage that's there to boost structural stiffness. We have a full gallery of photos of the MTM RS6 Clubsport direct from Geneva. Trust us, you'll want to have a look at this one. Related Video:
