2015 BMW 2 Series Convertible will flip its lid for $38,850

For the most part, they look almost identical to their coupe versions, except that they now boast an electrically folding soft top.
BMW is dropping the top of the 2 Series in early 2015 in the US with convertible versions of the 228i and M235i. They'll make their world debut at the Paris Motor Show later this year and will show their faces on this side of the pond at the 2014 Los Angeles International Auto Show.

BMW recalling nearly 570,000 1 Series, 3 Series and Z4 models over electrical issue

BMW is recalling roughly 570,000 vehicles in the United States and Canada due to faulty battery cable connectors that can fail, causing the engines in these cars to stall. Of the nearly 570,000 affected vehicles, just over 504,000 are here in the US.
The affected vehicles include 1 Series coupes and convertibles (both 128i and 135i) from the 2008 to 2011 model years; 3 Series sedans, coupes, convertibles and sport wagons (both 328i and 335i) from the 2007 to 2011 model years; and Z4 roadsters from the 2009 to 2011 model years.
According to the National Highway Traffic Safety Administration, "the connector for the positive battery cable connector and the corresponding terminal on the fuse box may degrade over time," which can eventually lead to a break in the electrical connection and a loss of power in the vehicle. If the car loses power, the engine can stall, which could possibly lead to a crash. The Detroit News reports that BMW knows of one minor collision in Canada as a result of this problem, but no injuries.

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.
