BMW performance engineering boss wants an M7

Audi has the S8, Mercedes has the S63 AMG and Jaguar has the XJR, but BMW has always held that an M7 wasn't justified, leaving its associated Alpina line to tackle that market with the B7 (pictured). The chief engineer at the M division, however, feels otherwise.
Speaking to Autocar, the BMW M development chief Albert Biermann indicated that he would like to see the M division do a performance version of the 7 Series to compete with the above-mentioned models, but that there are no current plans in place to do so. Neither did he specify what kind of engine it would have, or if it would be badged, for that matter, as an M7 or an M Performance model.
The latter is the approach which the M division is reportedly taking with performance versions of BMW crossovers beyond the X5 M and X6 M, such as the X3 and upcoming X4. The division is also said to be developing a performance-tuned xDrive system to compete with AMG's new all-wheel-drive models, as well as a potential M3 GT to join the new M3 sedan and M4 coupe with a slantback bodystyle.

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.

2015 BMW X6 keeps it weird

Say what you will about the BMW X6 - odd and ugly as it may be, it's actually been sort of successful for the German automaker. BMW has now sold some 250,000 examples of the X6 since its launch, and the company's fastback-crossover-coupe-whatever-thing gets a host of meaningful updates for the 2015 model year while not straying from its original mission.
Aside from its revised styling, most noticeably set apart by its larger, X5-inspired headlamps, the biggest update for the US-spec X6 is the addition of a rear-wheel-drive model, the sDrive35i. This trim joins the all-wheel-drive xDrive35i and xDrive50i, and since you should all be capable of decoding BMW's weird naming structure by now, you know this means the X6 will be offered with a choice of 3.0-liter turbocharged six-cylinder and twin-turbo 4.4-liter V8 engines. Fuel economy figures have not been released yet, but BMW says the new powertrains are more efficient than before, mated exclusively to an eight-speed automatic transmission regardless of cylinder count.
Look for the updated X6 to hit US showrooms this fall, following its debut this week in Paris. Expect pricing to be revealed closer to the model's on-sale date. Have a look below for all of the details.
