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's plans for next plug-in i model, due after 2020

BMW entered the fight in the green car ring with gusto thanks to the one-two punch of the i3 and the i8. However, it seems that there could be a wait ahead before the German's i sub-brand is ready to land another strike at the market. "We are still in the strategic research phase where we brainstorm," Klaus Frohlich, BMW Group development boss, said to Automotive News Europe about the future vehicle. He indicated the next new model to bear the i prefix wouldn't arrive until after 2020. Frohlich also underscored that the sub-brand's products wouldn't be based on a standard BMW product. The German brand was at one point rumored to have a model called either the i5 or i7 on the way that would have added a plug-in hybrid drivetrain to the 5 Series. Frohlich's statement would seem to invalidate that possibility. Although, there's nothing stopping the vehicle from carrying regular BMW branding in the vein of the X5 xDrive40e PHEV. The current i-badged models won't just stagnate on the market in the meantime, though. "We have a minimum 20 percent battery density improvement every three years, thus over the i3 and i8's life cycle, we will offer more performance, more range or a combination of the two," Frohlich said to Automotive News Europe. Sadly, current owners won't be able to upgrade to the improved parts, though. Rumors about a third i sub-brand model go back years with much of the talk swirling around the i5. In addition to the speculation about a 5-Series-based version, there was also supposed to be a stretched variant of the i3 with that name, possibly even with a hydrogen fuel cell version. Although, BMW claimed the vehicle was purely "hypothetical." Related Video:

BMW dishes on 'lightweight' 2014 M4

BMW's M cars are not what we'd call featherweights. Sure, the big, bruising twin-turbocharged V8s deliver a lot of power, but the fact of the matter is that more weight often equates to less fun.
Which is why we're so excited over a recent sit-down the blokes at Top Gear had with BMW's product manager for small and medium cars, Matt Collins. The chat led to talk of the M3 Coupe replacing M4. Collins confirmed that, yes, the new M4 would be turbocharged. The new engine will also be a six-cylinder, which should make purists happy.
