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.

Why are all US-bound BMW i3 EVs with range extenders stuck at port?

The first BMW i3 EVs have been delivered in the US, but in a quirk of the rules, none of them have been the range-extended versions. Long-time BMW electric vehicle driver Tom Moloughney discovered this fact the hard way. His i3 REx has been sitting at a New Jersey port for over a week and he's getting impatient. The problem is something Moloughney calls a "Monroney Hold." So, instead of sitting there fuming, Moloughney did a bit of research and discovered that the problem is something he calls a "Monroney Hold." He says that "the EPA certification has not been completed so BMW doesn't have a Monroney label (window sticker) to post in the window before the car leaves the port, which is required by law. The range extender option changes (shortens) the car's electric range, and also requires an official MPG rating so BMW couldn't use the same Monroney label as they did for the all electric i3." You can read more on his website, but it turns out that the story isn't so simple. For one thing, the EPA testing has been finished. Washington State representative Chad Magendaz told Moloughney that he asked the EPA for an official statement and got the following from Linc Wehrly, Director of the Light-Duty Vehicle Center Compliance Division: "EPA tested the i3 REx and provided the results of that testing to BMW on May 13th. EPA is not aware of anything that would prevent BMW from importing the vehicles since May 13th." Then there's the official word from BMW. Spokesman Dave Buchko told AutoblogGreen that: We are moving as quickly as possible to release the first BMW i3 Range-Extender models to BMW i Centers. Receipt of test data from the EPA is one step, but not the final step, in the process of receiving certification from the EPA. Rules do not permit the release of vehicles for sale until EPA labels are finalized, produced and affixed to any vehicle. Barring any unforeseen delays, we expect that to happen by the end of this week. We have never certified a vehicle like this before. We are taking every precaution to make sure that everything is done in a timely, but more importantly correct manner. In that Monroney labels cannot be produced until the EPA certification process is complete, the characterization [of a "Monroney Hold"] is not technically incorrect, but there is more to it than that, as is often true in life. On a lighter note, BMW donated a loaded i3 to Brad Pitt's Make It Right charity foundation as a fundraiser. Read about that below.
