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 M3 Sedan, M4 Coupe are officially revealed [w/video]

The new 3.0-liter inline-six makes 425 turbocharged horsepower from 5500 rpm all the way up to 7300 rpm.
BMW has announced the 2015 M3 Sedan and M4 Coupe, high-performance versions of the new 3 Series and 4 Series that launched this year. The new Ms have stirred controversy in a variety of ways, but one must remember that the M cars traditionally don't follow a specific mold.

2014 BMW M235i

We know a number of BMW owners who reside in the Munich brand's core demographic - upper-five- and six-figure professionals who like to keep their automotive brand credentials as highly respected among their peers as their alma maters or the letters after their names. Before heading to Las Vegas to drive the new M235i, we asked four of those owners, "What did you think of the E30 3 Series?" Although phrased differently, every one of them had the same answer: "What's that?"
You can counter that we just happened to query a tiny and ignorant sample size, and it's possible that you're right. Nevertheless, in every case,we were speaking to BMW's core demographic, the increasing legion of buyers who have fostered another year of record growth and are responsible for BMW retaining its global luxury title for nine straight years. Question that, and we'll refer you to BMW's marketing department, its several hundred PowerPoint slides and several thousand pages of research that prove the point.
That second-generation E30 3 Series built a name, a brand and an entire segment by defining BMW-ness as superlative driving dynamics meets luxury - shortened to the phrase, "The Ultimate Driving Machine." Thirty years later, just being a part of BMW-ness and luxury is enough for the majority of buyers. The superlative handling, that's optional, and 150 hairy guys meet every Tuesday to keep the old religion going, light torches, sing dirges to the siren long gone and bang on their keyboards about the apostasies of modern buyers.
