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.

Formula E gets wireless-charging BMW i8 safety car [w/video]

Racing series typically select a safety car appropriate to the kinds of racecars for which they'll be setting the pace. So you might find a Mercedes SLS pacing a Formula One grand prix, for example, and you're more likely to find a BMW M4 on duty at a DTM race and a Chevy Camaro or SS on an oval speedway for a NASCAR or Indy race. It would only stand to reason, then, that the FIA Formula E Championship kicking off next month in Beijing would press a plug-in into service as its safety car. But the organizers didn't go for your run-of-the-mill Nissan Leaf or Toyota Prius.
No, the safety car for Formula E will be a BMW i8 specially modified for the occasion. As you can see from the video below, the hybrid sports car packs a full roll cage, racing buckets with harnesses, special communications systems and on-board fire extinguishers. But that's not all.
In partnership with technological partner Qualcomm, the Formula E support fleet - including two examples each of the i8 and i3 - will feature inductive charging. So while one is out on the track, or at least sitting at the end of the pit lane waiting to be deployed - the other will be charging wirelessly. The vehicles are still pending FIA approval, and only one has been outfitted with the Qualcomm Halo wireless charging system (with the others to be retrofitted later), but they were all on hand for the recent practice race at Donnington Park.

Motorweek remembers the Bimmers that made us all fall in love

The enthusiast's tied-in-knots relationship with BMW makes the Bavarians one of those brands especially ripe for nostalgic flights. That's why as soon as we saw the opening shot of Motorweek's review of the 1986 BMW 325e and a 635Csi, we let out a long sigh and thought, "Ahhhhh, I remember those days..." The two red barons were the new entries for the year, the 325e offering a couple of extra doors for the first time, the 635CSi rounding up the powerplant's displacement compared to the 633CSi that preceded it. The inline six-cylinder in the current 335i sedan gets on with 300 horsepower; 28 years ago, the 325e made do with a 2.7-liter inline six offering 121 hp, taking 9.3 seconds to get to 60 miles per hour from a standstill. That's four seconds more than today. Those willing to pay $41,000 for the 635CSi got a 3.4-liter inline six with 182 hp, and Motorweek praised it as a "confident handling car that does feel big and clumsy at times." The more things change, you know... Check out the video for a reminder of how BMW got to be what it is, and to hear the most unusual use of the word "oriental" we've heard in a while.
