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 offering glitch fix for i3 with range extender

The BMW i3 has received quite a bit of acclaim since its release, with the electric powertrain grabbing a spot on Ward's 10 Best Engines list and the high-tech machine earning the nod as 2015 Green Car of the Year. However, Consumer Reports uncovered a vexing problem with the range-extended version of the hatchback that has plagued it until a recent software update. While CR was driving the range-extended i3 last year, it discovered that when the internal combustion engine was running during low states of charge, hard acceleration could suddenly cut back with no warning to the driver. This was especially problematic when passing. BMW knew about the issue and promised a software update in the spring. That improvement is now available. BMW spokesperson David Buchko tells Autoblog that the software update adds a percent-of-charge indicator to all models of the i3 to let drivers know just how much juice is left. For the range-extended model, it also provides a warning of possible power reduction when the charge reaches two percent. According to Consumer Reports, the revision lets the car anticipate needing more reserve power based on the topography from the navigation system, as well. For any i3 drivers who want the upgrade, they need to visit a dealer for installation, according to Buchko, but it should be come at no cost to owners. Related Video:

BMW 3.0 CSL Hommage evokes classic 1970s Bimmer design

BMW enjoys taking advantage of the annual Concorso d'Eleganza Villa d'Este as an opportunity to re-imagine some of company's vintage shapes in modern ways with concepts like the M1 Hommage, 328 Hommage, Concept 90 motorcycle, and even last year's Mini Superleggera. This year's event on the shores of Lake Como is no different, and the Bavarian brand is celebrating one of its great sports coupes from the 1970s with the BMW 3.0 CSL Hommage. Bathed in a shade called Golf Yellow that perfectly evokes the era of the original, the Hommage's design seems to incorporate a few cues from the current 6 Series into the classic look of the 3.0 CSL. However, the front end is actually a little ungainly to our eyes due to the massive grille, and the fenders that fold up over the hood. The laser headlights are a great touch because their X-shaped centers are inspired by old racecars. The design improves significantly in profile and really starts to show the inspiration from the original 3.0 CSL. This concept has some beautiful rear haunches, and the big, creased fenders lead the eye to the massive rear wing. The back end also maintains much of the vintage design, including the roof spoiler, but the shape gets modern touches. So while the source of this inspiration was a bit angular, the lines have been gently curved for the Hommage. Of course, a CSL must be lightweight, as signified by the last letter in its name. Where the original uses aluminum and Plexiglas to shed pounds, the Hommage uses carbon-fiber-reinforced plastic parts throughout the body. The interior is also made from CFRP, and occupants sit in quilted racing buckets. An especially cool touch is the V-shaped cross-member at the back that evokes the look of a roll cage, while being a bit more artistic. The only indication that BMW is giving about the 3.0 CSL Hommage's powertrain is that it uses an inline six with eBoost, but as a concept the engine doesn't really matter, anyway. Get a good look at the whole design in the gallery above. BMW 3.0 CSL Hommage. Racing flair with a touch of class. Munich/Cernobbio. Amid the audacious design studies and automotive beauties from a bygone era gathered at the Concorso d'Eleganza Villa d'Este, the BMW Group presents its new BMW 3.0 CSL Hommage – and in the process makes a pretty formidable statement of its own. This model is the BMW Design Team's tribute to the 3.0 CSL, a timeless classic and iconic BMW Coupe from the 1970s.
