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 reveals new X5 Security Plus in Moscow

A major player in the Russian market, BMW is heading to the Moscow Motor Show this month with a slew of local debuts... most of which we've already seen. But among all the new models making the trek from Bavaria to Moscow will be the new X5 Security Plus.
In a new-model launch that will surprise exactly no one, BMW's latest armored vehicle upgrades the X5 with enhanced protection for oligarchs against Chechen rebels, AK47-touting gangsters and missiles randomly falling on Crimean highways. Now meeting the VR6 standard of ballistic protection, the new X5 Security Plus incorporates reinforced bodywork, seats and joints, along with bulletproof glass.
Of course all that reinforcement (not to mention the jars of beluga caviar and bottles of Stoli in the glovebox) will come with a weight penalty, but the 4.4-liter twin-turbo V8 ought to do the trick, driving 450 horsepower through BMW's xDrive all-wheel-drive system to get the vehicle's occupants out of a war zone in a hurry.

Upcoming new Alpina B7 teased

BMW does not make an M7. It never has, despite rumors, trademark filings, and the actual desires of the people that would build such a car. That means that while we're stuck waiting for BMW to see how foolish not building an M is, the most potent 7 Series you can get wears an Alpina badge on the nose. Meet the newest version of that car... sort of. BMW and Alpina haven't taken the wraps off the next B7 just yet, opting instead for an opera-accompanied teaser of the new car undergoing track testing. The car is lightly camouflaged – there's enough to make it clear it's a 7 Series, but not so undisguised as to reveal too much of the Alpina bodywork. There's a more aggressive bumper, a meaty rear spoiler, and sharper side sills, along with what are probably Alpina-specific wheels, but more precise details are hard to discern. What isn't difficult to pick out, though, is ear-tingling exhaust note. The last two Alpina B7s have built on the standard 7 Series' engine, and this new model likely won't be any different. That should mean a breathed upon 4.4-liter, twin-turbocharged V8 which goes well above the unfettled car's 445 horsepower and 480 pound-feet of torque. The extra power, along with the donor car's new lightweight carbon-fiber passenger cell, should make for tantalizing performance capabilities. The current 750i xDrive takes 4.3 seconds to make the sprint, and the B7 model that this new machine will replace hits 62 in 4.6. We'd expect the upcoming B7 will do better. The teaser from BMW and Alpina doesn't indicate when the new model will debut, but we'll eat our proverbial hat if it doesn't happen in Geneva. Related Video:
