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.

See the BMW 3 Series morph through history in this animation

The BMW 3 Series is now over 40 years old, and the folks over at Donut Media have put together a very cool animation to commemorate its four decades on the road. The minute-and-a-half-long video shows some of the highlights of the 3er's career, with the side view morphing from the super-basic 1975 E21 316 to the Group 5 racecar based on the same chassis, and up to the current F80-body M3 in Austin Yellow, with stops along the way highlighting different body styles from each of the car's six generations. The color names are at least as interesting as the little info callouts scattered around the video, and the sound bites of racing commentary are a definite treat, so be sure to have your speakers on. Another plus is that you can halt the video between morphing and create some very weird looking BMWs. As a bonus, the creators offer posters of the iconic German cars. It's another clip in a series from Donut Media that brought us an earlier 911 evolution video, so be sure to watch that one as well for a quick automotive history recap. Donut Media is also asking for suggestions on what to morph next. You can leave your ideas in the YouTube comments.

Self-driving cars' problem (besides making them work): Too many players, not enough profit

For an detailed, interactive graphic about the many players in autonomous cars, click here. FRANKFURT/DETROIT — BMW and Daimler, the world's top luxury carmakers, have announced alliances with suppliers, talking up the virtues of having a bigger pool of engineers to develop a self-driving car. But another motive behind these deals, executives and industry experts told Reuters, is a concern that robocars may not live up to the profit expectations that drove an initial investment rush. Carmakers are increasingly looking to forego outright ownership of future autonomous driving systems in favor of spreading the investment burden and risk. The trend represents a clear shift in strategy from little more than a year ago when most automakers were pursuing standalone strategies focused on tackling the engineering challenge of developing a self-driving car, rather than on the business case. "Although it is a substantial market, it may not be worth the scale of investments currently being sunk into it," said a board member at one of the German carmakers, who declined to be identified because the matter is confidential. Dozens of companies — including carmakers and tech firms like Google and Uber — are vying for a market which, according to consulting firm Frost & Sullivan, will only make up about 10 to 15 percent of vehicles in Europe by 2030. There are sure to be losers. "It's impossible for me to believe there will be 50 successful autonomous vehicle software producers," said John Hoffecker, global vice chairman of Michigan-based consulting firm AlixPartners. In July last year, BMW became the first major carmaker to abandon its solo development of self-driving cars in favor of teaming up with chipmaker Intel and camera and software manufacturer Mobileye to build a platform for autonomous cars technology by 2021. The decision followed a trip by senior executives to visit startups and suppliers to gauge BMW's competitive position. "Sitting at other companies, one rattles off the technological challenges and safety aspects, and you come to realize that many of us are swimming in the same sludge," Klaus Buettner, BMW's vice president autonomous driving projects, told Reuters. "Everybody is investing billions.
