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.

2014 BMW Z4 offers minor refinements with a majorly orange wrapper

The redesigned BMW Z4 was rolled out onto the show floor at the Detroit Auto Show, with the example in question being an sDrive35is variant, with the just-less-than-screaming Hyper Orange Package. The exclusive colorway includes the metallic orange paintjob, as well as trim-specific seats, stitching and accents for the interior. More importantly, the 35is driveline means that you'll find a high-output version of the turbocharged 3.0-liter N54 engine, here outputting 335 horsepower and 332 pound-feet of torque, and a 7-speed DCT gearbox.
Two slightly less ferociously powered versions of the Z4 will be available for the new model year, too (both familiar). The Z4 sDrive35i is good for 300 hp and 300 lb-ft, while the still-potent sDrive28i features a 2.0-liter turbo four-cylinder making 240 hp and 260 lb-ft.

Hamann M6 Gran Coupe is all flared and shiny

Oh, Hamann. After rolling out the ridiculously pink Mystère at this year's Geneva Motor Show, the tuning company has worked its mirror-finishing magic on the BMW M6 Gran Coupe, debuting this, the aptly named "Mirror" at the Frankfurt Motor Show. It sure is shiny, and a full 40 millimeters wider than the standard M6 GC.
Hamann says that the, um, "tailor-made suit" exterior treatment is made up of a new front bumper spoiler with large air intakes, side skirts, a new rear spoiler, and wing extensions out back. And the end result is... well, let's just call it noticeable. The special BMW rides on unique 21-inch wheels and sits a full 25 millimeters closer to the ground, as well.
As far as we can tell, Hamann hasn't upgraded the M6's 4.4-liter twin-turbo V8 at all, though there's a new sport exhaust system that "depending on the application area, either noisily announce its presence or purr sportily." Sounds like it's as loud as its newfound appearance.
