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 rethinks all-wheel-drive M cars

BMW M hasn't been able to decide whether it wants to jump on the all-wheel-drive bandwagon or not (with the exceptions of the X5 M and the X6 M, which are based on AWD architecture). That might be changing though, since M's president Friedrich Nitschke recently realized that 70 to 80 percent of Mercedes-Benz E63 AMGs are ordered with all-wheel drive. Earlier this year, Nitschke said that there were no new AWD M models planned, so this comes as somewhat of a surprise.
"On our cars we are thinking of all-wheel drive, but it won't come before we get the successor of the M5 and M6," Nitschke said in a Motoring report. "That's the timing and it's not practical to react in the current life cycles."

BMW 4 Series Gran Coupe spotted wearing minimal camo, M Sport pack

The new BMW 4 Series is essentially the coupe version of the latest 3 Series. So it would stand to reason that the four-door version of the 4 Series, in turn, would be the 3 Series - right? Well, yes and no.
Just as BMW offers both a 5 Series sedan and a four-door version of the 6 Series called the Gran Coupe, so, too, will its 4-Series family expand. So following the release of the new 4 Series Convertible, here we have the latest batch of spy shots showing the upcoming 4 Series Gran Coupe - which in turn should not be confused with the hunchbacked 3 Series Gran Turismo, which is more of a sporty wagon than a four-door coupe.
The nearly ready test vehicle pictured here is wearing only minimal camouflage to hide some last few details, but also appears to be wearing the M Sport package that will bridge the gap (at least, visually speaking) between the base models and the M4 Gran Coupe that is all but certain to follow.
