BMW Motorad reveals Concept Stunt G 310 in Brazil

BMW has been on a bit of a concept motorcycle bent lately, and each has taken a decidedly different approach from one another. The Motorad division did the Path 22 scrambler concept in June, the Concept 101 custom bagger in May, the Concept Roadster last year, and the Concept 90 retro racer the year before. Now it's at it again with the Concept Stunt G 310. As you might have guessed, the G 310 is a stunt bike. Its compact form is built around a single-cylinder engine canted rearwards with a rotated cylinder head to help optimize the weight balance. The intake was moved forward and the exhaust towards the rear, mounted under the seat, to enable the rider's freedom of movement. It has long travel in the suspension, but still rides on a short wheelbase – perfect for impressing the crowds. To that end, it was designed with collaboration from four-time stunt riding champion Chris Pfeiffer. It's also got a lockable throttle so the rider can take his hands off the controls (not advisable for the rest of us). The beefed-up secondary rear brake can be actuated by a squeeze of the finger. Axle pegs allow for additional foot-placement options, red crash bars protect the mechanical elements, and a specially designed "stunt tail" is milled from solid aluminum and provides an additional foot-hold. The shape is adorned with an eye-catching neon livery designed to give the impression of movement, even when it's sitting still. The bike will be unveiled in Sao Paulo, Brazil, at South America's preeminent motorcycle show. BMW Concept Stunt G 310 – Street. Style. Stunt. 06.10.2015 Munich/Sao Paulo. With the world premiere of the BMW Concept Stunt G 310 at South America's largest motorcycle show, BMW Motorrad is presenting a completely new side: the uncompromising interpretation of an aggressive and agile stunt bike based on a single cylinder study. Thanks to his experience as a four-times World and European stunt riding champion, Chris Pfeiffer, contributed to the realisation of the BMW Concept Stunt 310. "Stunt riding is a demanding and multi-faceted sport. Ideally you need a compact, agile bike which is also stable and robust at the same time. You have to achieve the ideal balance between aggressiveness and control", explains Chris Pfeiffer. Compact proportions, highest-level agility.

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, Ferrari, VW cars use tungsten mined by terrorists

Bloomberg Markets is reporting that BMW, Volkswagen and Ferrari have been using tungsten ore sourced from Columbia's FARC rebel terrorists. The extensive story focuses on Columbia's illegal mining trade and calls into question the provenance of the rare ore that is used not only in crankshaft parts production, but is also found in the world's computing and telecommunications industry for use in screens.
The ore is mined by the FARC (Fuerzas Armadas Revolucionarias de Colombia, or Revolutionary Armed Forces of Colombia - People's Army), and exported to Pennsylvania, where it is refined. The refined ore is then sent over to Austria, where a company called Plansee turns it into a finished product. Now, it's important to note that we aren't talking about the world's supply of tungsten here. In 2012, Plansee's American refinery purchased 93.2 metric tons of tungsten, valued at $1.8 million. That's peanuts, with the entire Colombian tungsten mining industry producing just one percent of the world's supplies.
That doesn't make indirectly supporting FARC any more acceptable, though. BMW, VW and Ferrari are all committed to not accepting mineral supplies from the Democratic Republic of Congo, which is also in the grips of a guerrilla insurrection funded, in part, by illegal mining. The same commitment would figure to extend to Colombian mining, but as BMW points out, it's difficult for a multi-national manufacturer to know where every item in its supply chain comes from. A company spokesperson says as much, telling Bloomberg, "These few grams out of the billions of tons of raw materials passing through the BMW supply chain are of no practical relevance."
