BMW recalling 1 Series ActiveE over bad drivetrain housing

There are always growing pains when automakers introduce new technologies. BMW is learning this with the electric powetrain used on the 2011 BMW ActiveE. According to the National Highway Traffic Safety Administration, about half of the all-electric 1 Series coupes currently in the hands of the public are being recalled for a potential problem that could leave the cars stranded.
With 700 ActiveE models running around the US, 360 of these cars have insufficient sealing between the electric motor and transmission, which could lead to premature wear to the connection between the two, which in turn could result in a loss of propulsion. BMW started notifying affected owners by phone earlier this month.
While no automaker wants a recall on its hands, it's much better for BMW to learn such a lesson now on the low-production, lease-only ActiveE ahead of the car's successor, the BMW i3, which is expected to be a much higher-volume EV. Scroll down for the official recall notification.

BMW X4 reclaims dash of utility with Clemson student project [w/videos]

BMW seems willing to exploit every automotive niche it can find with creations like the four-door, 'crossover coupe' X4 and X6. Of course, these designs come with a compromise. That svelte fastback means that they just can't haul as much cargo as a more traditional, boxier hatchback. Fortunately, students at Clemson University's International Center for Automotive Research might have a novel solution: the engineering graduate program has turned the crossover into a unique pickup.
Dubbed Deep Orange 4 concept, this functional prototype has an enclosed cargo area with a sliding glass panel that opens up to expose a pickup bed if more room is needed. Think of it as the GMC Envoy XUV of German crossovers. This isn't just an X4 with its roof hacked off, though. The students actually started with an X3 and grafted on this top later in addition to the two barn doors for access to the bed.
To make this project even more impressive, this pickup-crossover could conceivably be produced. The graduate students conducted an in-plant analysis of BMW's manufacturing abilities and went back to the university to create a plan for a low-volume vehicle that could actually be built. "The students working on this phase of the project did an excellent job of keeping costs down while finding optimal integration opportunities," said Rich Morris, vice president of assembly at BMW Manufacturing, in the university's release.

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.
