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 M3 driving off cliff is a chilling PSA

We're a little shocked that the unnamed owner of this cliff-diving E46 BMW M3 would upload the in-car footage of his accident to YouTube. Not only that, he uploaded two videos: raw footage of his roll down the cliff (it looks like somewhere in the Southwest, maybe Arizona) and a tribute video for his BMW that suffered the most severe consequences of understeer. Not only does uploading the videos leave him wide open for judgment by fellow enthusiasts (just read the YouTube comments), but we imagine if the police and his insurance company somehow don't know about the incident already, they will shortly. Scroll below to view for yourself.
The raw footage shows the sort of driving that led to the M3's violent tumble, and it serves as a good public service announcement reminder for everyone out there: Just like the Spengler's streams, double yellow lines aren't meant to be crossed. Also, hard driving is one thing, but hammering on public roads at speeds clearly above your skill levels as a driver is not only a recipe for legal trouble, it's a script for ruining your car at the very least, if not your life.

2014 BMW 4 Series Coupe images leak out

Because embargoes were apparently made to be broken, images of the 2014 BMW 4 Series coupe have leaked onto the Internet ahead of the car's official debut thanks to Car Design News' Facebook page. As you'll recall, the 4 Series is the replacement for the outgoing 3 Series coupe, its nomenclature falling in line with the rest of BMW's lineup, where coupes and convertibles will be set apart from their sedan counterparts by one number.
As we can see in the photos, the 4 Series takes a lot of its design cues from the 3 Series on which it is based, but there's a lot more in the way of attractive body sculpting, and this production model stays true to the original 4 Series Coupe Concept that we saw at the Detroit Auto Show earlier this year.
We don't have official details to divulge just yet, but we can discern from the photos that the range-topping coupe will be the 435i model, likely powered by BMW's turbocharged 3.0-liter inline-six from the 335i. There will no doubt be a 428i model with a 2.0-liter turbo-four underhood, and we expect BMW to offer its xDrive all-wheel-drive system on both models. Much like the 3 Series, a variety of trim levels will be on offer, including a top-spec M Sport trim that you can see painted in Estoril Blue here.
