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 details Concept X5 eDrive ahead of New York debut

Already weighing more than most other types of vehicles and with the space to accommodate the extra equipment, crossovers and SUVs arguably make for one of the more ideal platforms to transform into a hybrid. And there have been a handful of them - like the Audi Q5, Infiniti QX60/Nissan Pathfinder, Porsche Cayenne/Volkswagen Touareg, Lexus RX450h/Toyota Highlander and Cadillac Escalade/Chevy Tahoe/GMC Yukon - but by and large the majority of hybrids on the market are sedans and hatchbacks. BMW, however, looks poised to join the minority with the X5.
The Bavarian automaker showcased the X5 eDrive concept at Frankfurt last year, and as promised, has now revealed the followup it will present at the New York Auto Show in just a few days. The new Concept X5 eDrive, as BMW has now revealed, pairs a 2.0-liter turbo four good for 245 horsepower to a 95-hp electric motor to deliver a combined 340 horsepower. Its lithium-ion battery can power it for up to 20 miles and at speeds up to 75 miles per hour before the gasoline engine needs to kick in. All that without sacrificing the vehicle's utility, maintaining an almost perfectly flat loading floor with 40:20:40 split-folding rear seats, and without sacrificing much on performance, either: with a 0-62 time of seven seconds flat, the X5 eDrive concept is quicker off the line than the production X5 with the 2.5-liter turbodiesel and just a tenth off of the 3.0-liter turbodiesel.
With the full technical details now released (you can delve into it all in the press release below), the only question remains when BMW will actually put the X5 eDrive into production. Given its appearance in New York, though, we gather that whenever it does reach showrooms, it'll reach American ones as well.

Check out the trick way you access the tire valve on this BMW Alpina B6

The wheels are one of the first things you notice when checking out the 2015 BMW Alpina B6 xDrive Gran Coupe. The 20-inch aluminum alloy rollers have 21 spokes that spray out from their hubs, creating one of Alpina's signature design features. But there's also plenty of function to go along with the stylistic form of this hotted-up BMW 6 Series Gran Coupe.
By rotating the Alpina roundel and unlocking the center hub, you gain access to the tire valve and bolts, which are hidden inside. They're literally kept under lock and key, and they protect your Alpina's wheels from the elements and theft. This unique center-fill system employing a hollow spoke isn't a new setup for the favored BMW tuner, but since Autoblog had one in our offices this week, we thought we'd take the opportunity to show the unique mechanism in case you haven't seen it before. Check it out in our brief video below.
