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 M5 spied as camouflage striptease continues

The facelifted BMW M5's striptease continues. The latest spy images of the super sedan show even more headlight and taillight details, on top of more overt signs of this car's character. Our first spy photos of the M5 showed a car with production 5 Series wheels and tiny quad exhaust pipes. The next set got sportier black wheels. But the latest shots depict a machine that gets the current M5 Competition Package's black wheels along with BMW M's trademark blue calipers, just like the current car. It also ditches the camouflage on the pillars, roof rails, and rear windows. Beyond those changes, stripping away some of the camouflage has shown modest tweaks. We're finally getting a good look at the updated, squared-off LED running lamps and the tweaked front fascia. Updates are even more minor in back. But there may be something more drastic at play with the taillights. Studying these shots, we can't really see any detailing in the rear lamps. There's a similar thing going on between the normal LEDs on the BMW M4 and the OLED units in the new M4 GTS. Backing up this speculation is a single shot of one of the rear turn signals illuminated. It doesn't look quite like the current car's signal, but we can't be certain. It's possible that the shots and the camouflage might be playing tricks on our eyes. And since this is the first time we've seen the updated M5 with production taillights, there's no real basis for comparison. Still, BMW's tantalizing new OLED tech is sure to proliferate beyond the M4 GTS. We just can't yet be certain if it's coming to the next M5. Related Video:

Upcoming new BMW X6 leaks out ahead of full reveal

The X5 may have been the first BMW crossover on the market when it arrived in 2000, opening the door to more high-riding Bavarians to follow, but it's been replaced twice over now. The X3 is on its second generation, and with the X1 having been introduced in 2009 and the X4 soon to hit showrooms, that makes the X6 - introduced in 2008 - the oldest crossover in the BMW lineup. But it won't be for much longer.
Soon BMW will reveal the all-new X6, based on the latest X5 but with that tell-tale slanted roofline. But before it gets the chance, a handful of images have leaked their way all over the Internet to give us an advance look at what to expect.
The overall shape of the new X6 comes across as familiar, if a bit less of an awkward take on the vehicle that (for better or worse) launched the crossover coupe segment. Up front the twin kidney grilles and headlights are larger, in keeping with the latest BMW design language, and the bumper less horizontal and more dynamic. Towards the back there's a sharp crease above the wheel arch blending into the more rakishly shaped tail lights, while the metallic vent behind the front wheel arch lends the flank an even sportier appearance.
