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 Coupe laps 'Ring in 7:52, bests outgoing M3

Comparing Nürburgring Nordschleife lap times is a bit of a black art, especially when looking at times officially set by manufacturers matched against other sources. Driver skill and weather conditions play a huge roll in determining a quality time. Still, it appears BMW fans have reason to celebrate because the new M4 Coupe beat the previous-generation M3 by 13 seconds in a recent test by Germany's Sport Auto magazine.
Sport Auto conducts what it calls the Supertest, where it runs performance cars around the 'Ring and the short course at Hockenheim to create its own database of comparable times. The M4 with a dual-clutch transmission, ceramic brakes and Michelin Pilot Supersport tires managed a quality 7 minutes 52 second lap around the 12.8-mile course, compared to 8:05 from the last M3, according to BimmerPost. The new coupe also beat the magazine's posted times for the Audi RS5 Coupe, which did it in 7:59, and Mercedes-Benz C63 AMG with an 8:01, but couldn't quite match the 7:44 set by a 911 Carrera S. Still, BMW must be somewhat pleased with these results of its new 425-horsepower coupe because it posted the magazine's cover and an image of the time on its official M Facebook page.
While the M4 apparently stands up to contemporaries and predecessors, new generations of the AMG and RS models are reportedly on the horizon. In other words, more tests will come.

BMW sets Guinness record for longest drift with new M5 [w/video]

In September of 2011, Chinese drifter Wang Qi broke the Guinness record for the world's longest sustained drift, doing 13 laps inside the Olympic Center Stadium in Tianlin, China for 5,802.3 meters. That was broken in February of this year by Abdo Feghali in Abu Dhabi drifting a new Chevrolet Camaro around a skidpad for 11,180 meters - almost seven miles. In March, BMW decided it wanted the record "back in the US," and set up a course at its BMW Performance Driving School near Greenville, South Carolina to get the job done. On May, 11 it was Mission Accomplished when Performance Center driver Johan Schwartz drifted an M5 around a skidpad continuously for 51.3 miles.
Despite that accomplishment, we're pretty sure that professional drifter Vaughn Gittin, Jr. isn't impressed. The way Guinness defines "drifting" can also describe a donut, which is effectively the kind of drifting that's been done for these last three records. BMW went even further by watering down the surface of the track, reducing the skill required and the need to change tires during the effort. On the other hand, you can't drift a car for long in a straight line, but perhaps there should be some clarification or classifications added to the milestones.
There's a short video below taken during the record-breaking run, and a press release from the company that did it.
