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 commits two R18 E-Tron Quattros to final Sebring race for LMP1 cars

We were baffled a few weeks back when the American Le Mans Series and Grand-Am Rolex Sports Car Series announced new classes that will make up their combined racing program in 2014. Gone from the list is the Le Mans Prototype class, otherwise known as LMP1. The LMP1 class has long been the top dog of endurance racing, both in Europe and the US, so we couldn't figure out why this newly minted racing series was jettisoning it like yesterday's donuts.
It appears as if Audi is confused by the move as well. The German brand has announced it will participate in this year's ALMS opening round, the famed 12 Hours of Sebring, as it does every year, and bringing two Audi R18 E-Tron Quattro hybrid race cars with which to compete. Unlike every other year, Audi is treating this year's race as its potential swan song in this famous Florida race.
There's a good reason that Audi is so fond of the 12 Hours of Sebring, as it debuted the gas-powered R8R there in 1999 that kicked off its participation in the upper echelon of endurance racing. The R8R preceded the R8, which debuted at Sebring in 2000 and won that race, starting an amazing career for that car that included five more wins at Sebring. The R8 was followed by the R10, then the R15 and R18, and finally we wind up at today's R18 E-Tron Quattro - all winners, all dominant, all exciting to watch.

Audi A8 super high-tech headlight teased, whole car coming Aug 21

We have to wait one more week before we get to see the 2015 Audi A8 and S8, but it doesn't look like Audi is going to stay quiet until then. After releasing a pair of teaser videos over the last week, it has now released a first detailed picture of the new A8 revealing the trick Matrix LED headlight.
Between the high-beam and low-beam lights, the headlights contain 43 LEDs (not including those for the DRL/turn signal), but the innovative part of Matrix LED system is that a camera can control the high-beam lights - by either dimming them or shutting them off - when other vehicles are detected on the road to prevent the lights from distracting other drivers. Of course the big question remaining is if Audi can get these new headlights to pass the National Highway Traffic Safety Administration and its Federal Motor Vehicle Safety Standards. The taillights also get a cool design with 24 LEDs that use a sequential turn signal
As for the debut of the A8 and S8, we already knew the sedans would be unveiled on August 21 ahead of the Frankfurt Motor Show, but Audi finally made it officially official in a press release, which is posted below. Also be sure to check out the pair of teaser videos Audi has released for these cars recently.
