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 recalling all 2000-06 3 Series models over airbags in US, 1.6M globally

We just can't seem to get away from recalls involving the faulty airbag inflators supplied by Takata. There are already millions of vehicles in need of repair as a result of these ever-expanding campaigns, and BMW is adding another 1.6 million worldwide. The Bavarian automaker is issuing a recall for certain 3 Series models, including 574,000 of them in the US, to replace the passenger-side, front airbag inflator.
Specifically, the campaign covers 3 Series models from the 2000 through 2006 model years built between May 1999 and August 2006. "It's only the E46" generation of cars that are affected, which are now two model revisions old, according to BMW of North America spokesperson Matt Russell, speaking to Autoblog.
These models suffer the same problem as the rest of the vehicles with the faulty inflators. It's possible for the part to rupture during airbag deployment and possibly spray shrapnel at the occupant. However, according to BMW, the automaker isn't aware of any actual cases of this happening in any of its vehicles.

BMW pondering hardcore M4 to celebrate 100 years?

2013 is the year for Lamborghini, Aston Martin and the Porsche 911, but 2016 will be the year for BMW. That's when the Munich-based maker of the Ultimate Driving Machine will celebrate its 100th birthday, with what will probably be a year-long celebration. Part of that 365-day party will, reportedly, be an even hotter version of the new BMW M4, which is set to debut in January at the Detroit Auto Show.
Yes, according to Australia's Car Sales, the über-M4 has been hinted at by higher-ups at BMW's M division, who claim the rear seats will be removed, much like the M3 GTS, while other weight-saving measures will be used to try and bring the M4's weight below 3,000 pounds. There's no mention of engine mods, but if the M4's biturbocharged six is as good as we think it'll be, that's not a deal-breaker for us.
The lightening process on the so-called M4 GTS would involve replacing the hood and front fenders with parts made of carbon fiber, while the doors would switch from steel to aluminum. Besides the deletion of the rear seats, Car Sales is predicting lightweight racing buckets, with a carbon-fiber shell and a minimal amount of padding. Expect lots and lots of Alcantara, in place of leather.
