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 almost ready to roll out new 2 Series cabriolet

The 2 Series is a relatively new member of the BMW family, having been spun off of the 1 Series (itself one of the company's youngest lines) just last year. So far the range has been split between the Active Tourer and the 2 Series Coupe, but soon the latter will breed a new compact convertible to take the place of the outgoing 1 Series cabriolet, and here we have our best look at it yet.
Spied with the most minimal camouflage and its top down while undergoing its final rounds of development testing, this pre-production 2 Series cabrio looks about ready for show time. While the Active Tourer is based on a different front-drive platform, this convertible is, as you might have guessed, essentially a 2 Series Coupe with a folding fabric roof. That means rear-wheel drive (or potentially all-wheel drive if BMW extends its availability from the coupe to the convertible) win either 228i or M235i specification - both of them turbocharged, the former with a 240-horsepower, 2.0-liter four and the latter with the 320-hp, 3.0-liter inline-six.
Considering that BMW got an approximately $8k premium for the 1 Series convertible over the coupe, expect the 2 Series cabrio to start at a little over $40k for the 228i and top out at around $53k for the M235i xDrive convertible. That is, assuming BMW offers it in that top spec, because at that rate we're getting perilously close to the $54,900 base price of the 435i convertible.

BMW 4 Series Gran Coupe caught without cladding

Like it or not, the majority of BMW 3 Series variants are on their way out, and the 4 Series models are hotly embroiled in the testing needed to replace them. We've now driven the basic 4 Series, seen spy photographs of the 4 Series Convertible and both versions of the M4 and today we get a better-than-ever look at the 4 Series Gran Coupe.
And, mostly dependent on your personal disposition towards four-dour coupes, that look should be a pleasant thing. The long, swooping Gran Coupe may be roughly similar in size to the related 3 Series GT, but it has been sculpted with beauty in mind rather than crossover function. We expect that those details still hidden by the body cladding here, mostly front and rear, can be filled in by simply remembering what the standard 4 Series looks like and squinting your eyes a bit. Subtlety is thy name, BMW variants.
As for the mechanicals, well, we expect to have the very same greasy bits under the hood and beneath the car that are found in the 4 Series lineup, too.
