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.

BMW recalling a grand total of three X3s over instrument panel defect

We've seen big recalls and we've seen small ones. Some involve millions of vehicles, and some - like the Infiniti Q50 recall on which we reported just the other day - involve just a couple dozen. But this has to be the smallest recall we've seen yet.
"Due to a production process error" in the BMW X3, states the National Highway Traffic Safety Administration in the notice below, "the team seam on the instrument panel was not manufactured correctly." Big friggin' whoop, you say? Well, NHTSA points out that it could hinder the deployment of the airbag and send fractures flying everywhere.
The problem was discovered in a select few examples of the 2013 BMW X3 - both xDrive 28i and 35i models - manufactured in the later part of February this year. And by "select few," we literally mean a few - as in three. Three examples are being recalled. If you happen to be one of those three owners, expect to hear from your local dealership.
