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.

BMW 2 Series specs leaked?

Thanks to spy shots from earlier in the year, we already know what the new BMW 2 Series will look like, but now we know a lot more about the coupe courtesy of an apparent BMW South Africa error and some quick-clicking enthusiasts. Though the information no longer appears to be posted on BMW's South African website, 2addicts.com managed to grab most of the details for the new coupe, including the model lineup, specs and most (if not all) of the options list for the upcoming replacement for the 1 Series.
Just like the latest 3 Series, the 2 Series model lineup starts at the 220i powered by a 2.0-liter inline four-cylinder, but the more exciting BMW figures to be the M235i with its 320-hp, 3.0-liter straight-six. With the automatic transmission, the info says that the M235i weights 3,240 pounds and will be able to accelerate from 0-62 miles per hour in 4.8 seconds - making it both lighter and quicker than the 135is currently offered in the US. The base 220i coupe should also be fun to drive with its 180 horsepower and sub-3,000 pound curb weight.
A quick side-by-side comparison of the dimensions for the base 220i with our current base 128i shows that the new coupe rides on a longer wheelbase (105.9 in. vs. 104.7 in.), is about two inches longer (174.4 in. vs. 172.2 in.) and is an inch wider (69.8 in. vs. 68.8 in.). 2addicts.com even shows available paint colors, interior trim options and lists pricing for South African-spec models. Head on over to the forum to check out all the info they have posted, but we expect the 2 Series to be unveiled at the Detroit Auto Show early next year.

Child cobalt miners: Automakers pledge ethical minerals sourcing for EVs

BERLIN - Leading carmakers including Volkswagen and Toyota pledged on Wednesday to uphold ethical and socially responsible standards in their purchases of minerals for an expected boom in electric vehicle production. Demand for minerals such as cobalt, graphite and lithium is forecast to soar in the coming years as governments crack down on vehicle pollution and carmakers step up their investments in electric models. To cover its plans for more than 80 new models by 2025, Volkswagen alone is looking for partners in China, Europe and North America to provide battery cells and related technology worth more than 50 billion euros ($59 billion). Talks with major cobalt producers, including Glencore, at VW's Wolfsburg headquarters last week ended without a deal. More than half of the world's cobalt comes from the Democratic Republic of Congo, a country racked by political instability and legal opacity, and where child labor is used in mines. On Wednesday, a group of 10 leading passenger-car and truck manufacturers announced an initiative to jointly identify and address ethical, environmental, human and labor rights issues in raw materials sourcing. The partnership dubbed "Drive Sustainability" consists of VW, Toyota Motor Europe, Ford, Daimler, BMW, Honda, Jaguar Land Rover, Volvo Cars and truckmakers Scania and Volvo. The alliance "will assess the risks posed by the top raw materials (such as mica, cobalt, rubber and leather) in the automotive sector," said Stefan Crets of the CSR Europe business network. "This will allow Drive Sustainability to identify the most impactful activities to pursue" to address issues within the supply chain.Reporting by Andreas Cremer.Related Video: Image Credit: Michael Robinson Chavez/The Washington Post via Getty Images Green BMW Ford Honda Jaguar Land Rover Mercedes-Benz Automakers Toyota Volkswagen Volvo Green Automakers Green Culture Electric Scania ethics mining
