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.

Recharge Wrap-up: Nissan Leaf in Puerto Rico, BMW i3 REx tax-free in NJ, BC2BC cancelled [UPDATE]

*UPDATE: Nissan has released a video of the Leaf in Puerto Rico, so we've embedded it below. Envia Systems will develop battery technology for United States Advanced Battery Consortium (USABC), a subsidiary of the United States Council for Automotive Research (USCAR). The $7.7 million contract, co-funded by the US Department of Energy (DOE), involves a 36-month development program focusing on high-energy cathode and anode material for lithium-ion batteries and pouch cells for electric vehicles. The goal, of course, is to create better energy storage for less money in an effort to make commercial EVs more efficient and affordable. For the DOE, this also equates to energy security, energy independence and national security. Read more in the press release at the bottom of the page. The US and China have agreed to work together more closely on EVs, energy and climate issues. US Secretary of Energy Ernest Moniz went to Beijing for the sixth US-China Strategic and Economic Dialogue to meet with leaders. While there, Moniz and Wu Xinxiong of China's National Energy Administration (NEA) signed a memorandum of understanding allowing the DOE and NEA to share information regarding oil reserves. The groups will meet yearly to learn more about how each other manages petroleum stockpiles and policy. Moniz also met with Minister Miao Wei of the Chinese Ministry of Industry and Information Technology and signed an MOU to cooperate on electric vehicles and "related technologies," including the "inter-operability of electric vehicles." Read more at the Energy Department website. August's BC2BC all-electric vehicle rally, billed as the largest gathering of electric vehicles, has been cancelled. The event, which was to include a drive up the entire coast from Mexico to British Columbia with smaller events along the route, failed to bring in the needed sponsorship to hold the rally for its third year. A Facebook post from organizer Tony Williams also cited loss of venue and lack of support from automakers - "particularly Nissan and Tesla" - as hardships. The event was scheduled to take place August 9 through 17, with only battery electric vehicles invited to take part - no plug-in hybrids or range-extended vehicles. Williams said he'd only try a similar event in the future if sponsorship were provided up front. Read more at Green Car Reports. The Nissan Leaf will finally go on sale in Puerto Rico.

Tesla, BMW and Nissan meeting in secret to discuss charging tech

It's interesting what's happening in the electric vehicle field. It used to be that BMW and Tesla were competitors. Then – and of course they're still competing, especially in the public mind – they were working together on ... something. Maybe. And now, the Financial Times reports that the two luxury automakers are meeting with Nissan. Again, maybe. The scuttlebutt is that the three companies are interested in working together on something to do with charging electric vehicles, potentially a global recharging standard. Currently, when it comes to fast charging, BMW uses the SAE Combo standard, Nissan uses CHAdeMO and Tesla uses its own Superchargers. The meeting was prompted by Tesla opening of all of its patents the other day, FT says. Speaking during the recent annual shareholder meeting, Musk said he was "more than happy to have other manufacturers" use Tesla's Superchargers but that, "there is no other electric car that can accept anything close to 135 kilowatts." Let's assume the technical hurdle can be overcome. With any potential patent/licensing problems out of the way, these discussions with BMW and Nissan might be revolving around this other angle that Musk mentioned: "They (other automakers) just have to contribute to the capital cost, so figure out what percentage of the time are their cars using the Supercharger network and then they can make a contribution proportionate to their customer usage of the Supercharger network." That certainly sounds like something that could take some time to figure out.
