BMW to offer carbon fiber wheels in a year or two

The Citroën SM sat on the first set of production glass fiber and resin wheels in 1972 when parent company Michelin developed the exotic hoops in order to take the SM rallying. It wasn't until 2008 that we got the first all-carbon-fiber wheel for passenger cars in the form of a prototype model from Weds Sports in Japan that remained a prototype. Australian company Carbon Revolution followed that a year later with its CR-9 all-CF wheel, first introduced on the Shelby Ultimate Aero and now available for independent purchase for about $15,000 per set. BMW could be the first OEM to offer entire wheels in carbon fiber reinforced plastic in two years.
The wheels - either all-CFRP or using a CFRP rim and alloy spokes - were shown off during BMW's Innovation Days in Munich and are products of the development work done on its i-branded cars. The full-CFRP wheel is 35-percent lighter than a forged alloy wheel, the hybrid alloy and CFRP wheel is 25-percent lighter, making for a decent drop in unsprung rotating weight. As demonstrators during a tech day the wheels aren't yet in the pipeline for production and EU approval, but an article in Auto Express claims that they could be on the market as soon as two years from now.
Other possible parts include a full carbon fiber steering wheel and propeller shaft, the latter of which is coming as a single-piece component on the new M3 and M4. BMW is also talking up its use of secondary carbon fiber - waste material from i3 and i8 production - that can be used for items like IP support structures, seat frames and spare wheels in place of traditional metals like aluminum and magnesium. There's an excerpt of the Innovation Day press release below with more details.

2015 BMW X4 gets its small-screen debut

It's easy to dismiss the 2015 BMW X4. On one hand, the high-style crossover seems more like a boardroom decision than a practical one. In a world with the 3 Series, 4 Series, X3, 3 Series GT and 4 Series Gran Coupe, is BMW really being inundated with requests for a baby X6? Of course, when we finally got behind the wheel of the CUV for our First Drive, it proved rather entertaining, and certainly the X6's global sales success suggests that it's worth the relatively low-cost risk for the Bavarian automaker.
Now, it's the general public's chance to weigh in on the latest crossover Bimmer and vote with their dollars. The X4 is just hitting showrooms in the US, and BMW is beginning its marketing campaign for it with the slogan "Embrace the Unknown." The first TV ad shows off the CUV driving through the world's major cities as they undulate like the rolling ocean. A woman flatly says phrases starting with "Go," while a synth-heavy score plays underneath that wouldn't be out of place over the end credits in an '80s sci-fi movie.
Visually, it's actually kind of a cool ad and evokes some of the special effects from Inception. Focusing on an urban atmosphere is probably a good idea, too, because the percentage of X4s going offroad is likely to be in the low single digits, if that. Now, let's see if BMW buyers are willing to embrace the unknown of the X4. Scroll down to watch it for yourself.

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.
