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.

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 launches new M Performance accessories for M5, M6

Those looking to make their stock BMW look like an M model might be interested in an M Sport package. But those who already drive an M model and want that extra bit of attitude to take it over the top look towards the M Performance Accessories catalog, to which BMW has just added a new range of add-ons for the M5 and M6.
The new range of accessories include a titanium exhaust from Akrapovic that's 22 pounds lighter and an extra bit throatier than the stock unit. BMW's also offering a carbon-ceramic brake kit and 20-inch alloys to accommodate them, as well as a carbon aero kit, carbon interior trim and those trademark stripes for the truly extroverted BMW performance enthusiast.
You can check them out in the gallery above and the press release below to see what Martin Tomzczk, the DTM driver sponsored by BMW M Performance Accessories, chose for his matte black M6 Gran Coupe daily driver.
