BMW broadens engine bolt recall to nearly half-million cars worldwide

Almost one month ago, we reported on a BMW investigation into a potentially defective bolt that lived in the company's VANOS variable valve timing system. At that point, the potential recall was seemingly limited to Chinese-market cars; the company was filing a recall application with Chinese officials.
Today, Bloomberg is reporting that the engine bolt issue has expanded into a recall for several world markets, involving some 489,000 vehicles. BMW was able to verify that report to Autoblog, while also providing a great deal more detail about the issue and vehicles affected.
The recall affects vehicles powered by N55 inline six-cylinder gasoline engines equipped with VANOS and Valvetronic technologies. 1 Series, 3 Series, 5 Series and 5 Series Gran Turismo, X3, X5, X6 and Z4 models from the 2010 to 2012 model years are included, as is the 2012 6 Series.

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 i3 called 'most revolutionary car' since Ford Model T

The Ultimate Driving Machine, or at least one of them, may also be the Ultimate Engineering Success. Consultant Munro & Associates, which specializes in automotive tear-down analysis, pretty much said as much when taking an under-the-skin look at the BMW i3 plug-in. In short, the firm liked what it saw. Presenting at Detroit's Plastic's in Automotive conference this week, Munro CEO Sandy Munro called BMW's first mast-produced plug-in model the most revolutionary car "since Henry Ford's Model T." The car earned big points for its substantial uses of materials that are both lightweight (key for any plug-in's range) and recyclable. BMW has touted these advantages all along. In late 2013, the German automaker went as far as saying its use of carbon fiber reinforced plastic (CFRP) would reduce customer costs related to both repair and insurance. The i3 went on sale in the US last May and, by the end of the year, moved more than 6,000 units here. It sold almost 17,800 The i3 last November also was named the Green Car of the Year at the Los Angeles Auto Show, beating out models such as the compressed-natural-gas-powered Chevrolet Impala B-Fuel and the Audi A3 TDI diesel. Munro made news earlier this week when it offered a free i3 for anyone who bought the master- or OEM-level version of the report, though the report isn't cheap and that offered disappeared once Munro made his presentation. Check out Munro & Associates' press release below. Munro Discusses Groundbreaking Technology Finds from BMW i3 Teardown at Plastics in Automotive Conference; Offers New BMW i3 for Purchasers of Master-level Report DETROIT, Jan. 14, 2015 /PRNewswire/ -- During today's Plastics in Automotive Conference in Detroit, Sandy Munro, CEO of Munro & Associates, Inc., discussed – for the first time publicly – his consulting firm's findings from its extensive deep-dive teardown, costing and benchmark study of the BMW i3 urban electric car. During his presentation, "Deconstructing the BMW i3: Groundbreaking Technology and the Composite Car," Munro discussed the carbon fiber life module, polymer components, recyclability and safety of what he considers to be "the most revolutionary car in terms of creative engineering and manufacturing since Henry Ford's Model T." During the presentation, Munro focused on four crucial aspects of the BMW i3: the manufacturing of its carbon fiber life module; its polymer components; recyclability; and safety.
