BMW X4 tunes up its crossover game in Germany

Except for the fancy wheels and the overly expressive fascias, the production version of the BMW X4 looks like it will carry over practically untouched from what we saw in the X4 Concept several months back. With the same fastback roofline as the concept, these spy shots show that the X4 is taking shape to be a baby version of the BMW X6.
Sharing the same platform as the X3, the lower and wider X4 will be positioned slightly more upmarket - as is the case with the X5 and X6. We hear that this could mean that the X4 will ditch the X3's base engine to give an even sportier feel right out of the gate, but word has it that an M version will being showing up down the road as well.
BMW has already revealed what it plans to show off at the Frankfurt Motor Show (i3, 4 Series Coupe, next-gen X5, refreshed 5 Series, X5 Concept eDrive plug-in hybrid and Concept Active Tourer Outdoor), so barring any surprised we definitely won't be seeing the X4 there. At this point, with as close to production as these images would have us believe, our best guess would be that we'll see the X4's official unveiling happen either at LA or Detroit.

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 i8 official images leak ahead of Frankfurt [w/video]

The new BMW i8 plug-in electric supercar isn't set to make its official debut until September 10, when it will glide onto the Frankfurt Motor Show stage amidst a sea of flash photography. Of course, that isn't so true in today's world, where debuts are always preceded (often carefully) by "leaks."
Take this trio of images of the BMW i8 - there's just enough of the exterior on display in the profile shot to draw attention, without showing important styling points that might be present on the front or back of the car. The same goes for the video attached below. The cabin shot is cool, but isn't particularly earth-shattering when it comes to BMW interiors. As for the skeletal shot, we can see the 1.5-liter, turbocharged engine positioned between the rear axles, the battery pack found in what would be the transmission tunnel and the front-mounted electric motors.
We'll have a full set of live images when the BMW i8 makes its debut in Frankfurt next week. Until then, have a look in the gallery and at the video below, and let us know what you think of BMW's next big thing.
