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 i8 with 500+ horsepower in the cards?

While BMW makes plenty of machinery to keep enthusiasts interested, its most enticing models are often based on more ordinary ones. That's what made the arrival of the i8 so captivating, emerging as the first stand-alone BMW sports coupe since the M1. But if its dual purpose - trying its best to both embrace the earth and traverse it rapidly - somehow left you disappointed, the next development could prove to fix that.
According to Automobile, BMW is working on a more potent i8S model. The hardcore version of the hybrid sports car would offer more power and a stiffened chassis to make it that much more aggressive. The Bavarian automaker is reportedly still evaluating two potential powertrain options: The first would pair a 2.0-liter twin-turbo four-cylinder good for 320 horsepower to an electric motor with another 204 hp. The second would use a 3.0-liter straight six with 480 hp and an electric motor with 109 hp. Both would be mated to a nine-speed dual-clutch transmission and an integrated starter motor packing an extra 27 hp.
Either way, we'd be looking at a combined output well in excess of 500 horsepower - far more than the existing i8's 228-hp turbo three and 129-hp electric motor - dropping the 0-62 time down from 4.1 seconds to an estimated 3.5. Couple that to a more advanced carbon chassis, wider tires and other goodies, and the i8 would be transformed into a far more capable performance machine than it already is.

Can the government mechanically force you to wear your seatbelt? [w/poll]

The National Highway Traffic Administration is considering the use of ignition interlocks in vehicles that would require the seatbelts of occupied seats to be fastened in order to drive the car, Automotive News reports, four decades after Congress moved to prevent manufacturers from installing them in cars sold in the US market. Following a transportation bill passed last year that lift some of the restrictions on seatbelt interlocks, automakers such as BMW are considering the benefits of using them in future cars. Now, before you go crying about your lost freedom, keep reading.
BMW said in an October 2012 petition that the use of seatbelt interlocks would allow the company to make lighter and more spacious vehicles, if the devices could be used in lieu of unbelted crash tests. The crash test has required the addition of bulky safety features, such as knee bolsters, that aren't as necessary when occupants are buckled up, especially when considering the dizzyng list of safety features that come standard on today's cars. Europe, which has a higher rate of seatbelt use than in the US, doesn't perform unbelted crash tests on cars sold there.
