BMW shows up-armored X5 concept and we can't get near it

BMW has brought a slightly different concept vehicle to the 2013 Frankfurt Motor Show. Rather than something that foreshadows a future product or a new design direction, the Munich-based manufacturer has brought an X5 that's designed to be shot at. It's called the Concept X5 Security Plus. The Concept X5 name is a bit misleading, though. It's based on the 2014 X5, while BMW already builds an armored CUV, called the X5 Security. The concept tag has to do with the "Security Plus" part.
Engineered to be compliant with VR6 security standards - the current X5 Security is for VR4 standards - the Concept X5 will quite happily shrug off direct attacks from an AK-47. Thanks to sealed joints, high-strength steel moldings, high-performance steel body panels and special, polycarbonate-coated security glass, Kalashnikov's finest, whether used as a firearm or as a melee weapon, would be useless against this X5.
Built alongside the standard X5 in BMW's Spartanburg, SC factory, the X5 is shipped to a BMW facility in Toluca, Mexico for installation of the armor and security features. The company claims this delivers a more thoroughly engineered protective solution than aftermarket retrofitting.

BMW X4 slantback is nearly here

Another day, another new BMW spied. Sometimes it feels like Bimmer is developing so many new models that in the future, every buyer will get their own unique car. The latest one spied is the upcoming BMW X4 that was launched as a concept nearly a year ago. The Bavarians still see a need to camouflage the rear end of its prototypes, though.
As you can see, the production version is hewing very closely to the concept. If you peer around the camo, the headlights have the same shape, but the foglights are a new addition. The rear roofline seems quite similar to concept, too, but the back end is still somewhat more mysterious because the masking and dirt hide a lot. Still, it doesn't seem like the production model is going to be radically different from the concept based on the previous test cars we spied in the past. It also strikes us as very similar in size and form to the already available 3 Series Gran Turismo, with which it is expected to share a great deal.
Our wait might not be very long to see the midsize German CUV undisguised, because the X4's debut is rumored for the New York Auto Show on April 16 with a reveal as early as March 14.

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.
