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 M4 Concept beckons the new golden child of M cars

Ushering in the next-generation of two-door M performance cars for BMW, the new M4 Concept was officially unveiled at the Pebble Beach Concours d'Elegance last night after an unceremonious embargo leak yesterday afternoon. The reality of the fact that we will never again have a new M3 Coupe is a little easier to deal with after browsing the M4 Concept's sleek and sporty lines.
As was the case with the Concept 4 Series Coupe, we expect the this M4 to transition from concept car to production coupe with very few changes. Among the features we's bet against making it into production include the front splitter and the exhaust tips - both made from carbon fiber. Other notable details are the aero-shaped mirrors, the subtle M stripes on the carbon fiber roof and the 20-inch wheels exposing big six-piston from brakes. If it were up to us, we'd say bring this car to production as is - except for the paint color.
There is still no word on the M4's powertrain or if it will even offer a manual geabox, but we would imagine that we'll be seeing this car in production form, complete with all of those details at the LA Auto Show.

BMW M4 sheds some camouflage for latest test run

Last time we saw the upcoming BMW M4 out testing, it was heavily clad with camouflage and decidedly homely looking (as most early development mules are). But in this latest set of photos, the M3 coupe successor has started to come into its own skin, and we're seeing a shape more closely akin to that of a rendering we brought you a few months back.
Unsurprisingly, the M4 coupe looks very similar to the 4 Series Concept that BMW debuted at the Detroit Auto Show earlier this year. And while non-M version of the 4er will likely look a bit more sedate, these spy shots clearly show an aggressive front fascia, large wheels and the usual quad-exhaust rounding out the rear end.
Naturally, the M3 sedan will launch before this M4 coupe (and convertible), and powertrain details are still unclear as of this writing. We understand that the current M3's naturally aspirated V8 will be axed in favor of some sort of turbocharged six-cylinder engine, and we've heard plenty of rumors as to what, exactly, it might be, but we have yet to hear any official confirmation.
