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 M boss denies supercar collaboration with McLaren

The first time there was a McLaren Honda Formula 1 team, McLaren did some moonlighting with BMW on a supercar for all time, the F1. It just so happens that McLaren Honda is a thing again, and Car magazine recently ran a piece saying McLaren and BMW would get back together on another hopped-up coupe with roughly the same working agreement as before: BMW supplies a screaming V8, McLaren builds the body to go around it. Only this time the car would be a BMW model, not a McLaren, and be BMW's version of the next-generation McLaren 650S. The Car piece said that BMW head of R&D Klaus Frolich first got in touch with McLaren nine months ago, however, the head of BMW's M division, Frank van Meel, said he doesn't know anything about it. Mentioning every BMW exec referred to in the story, van Meel told Australia's Motoring, "I haven't had a phone call, [CEO] Harald Kruger hasn't had a phone call, and Klaus Frohlich hasn't had a phone call." The Car story said the reason BMW hasn't done a conventionally powered exotic recently is that former CEO Norbert Reithofer didn't want anything to eclipse the i8, the i brand, and the eco credentials the brand is charged with promoting. Changes in the executive suite – new CEO, new M boss, new R&D chief – were thought to meant changes in approach. Not according to van Meel, who gave those same i brand reasons to Motoring as then reasons BMW has no interest in a 750-horsepower, quad-turbo coupe. On top of that, after spending billions to move the game forward with in-house carbon fiber technology, van Meel asked, "I don't understand why we would need to work with McLaren for a supercar anyway. All of the technologies the story suggested are technologies that are core competences here at BMW and at M. Nobody in the world is more advanced with carbon-fibre than we are." The extent of the denial is so detailed that we're inclined to believe BMW on this one; cover stories usually stop at curt phrases like "We have no knowledge of that" or "We don't comment on future product." So you can put away your dreams of a McLaren F1 Part Two. For now. Related Video:

ROEV lets you use multiple charging networks with one account

It may be a textbook case of a first-world problem, but any EV driver who doesn't want to carry two or three plug-in vehicle charging station cards when one would do is about to get a little smile on their face. This morning at the LA Auto Show, the new ROEV Association was announced that will let EV drivers carry just the one card. While you would think the all-caps ROEV stands for something, none of the pre-announcement materials nor the website explain it that way. Instead, it seems to just be a play on rove, which makes a lot of sense. There are three charging networks involved in ROEV: Blink, ChargePoint, and EVgo. Conveniently, these are the three largest in the US and have a combined 17,500 public chargers across the country. If you've got an account with one of these three networks, once ROEV goes into effect (expected in the spring of 2016), you'll be able to use that card at any participating charger without signing up for another account. Your personal details are kept private, ROEV says, and the companies coordinate behind the scenes to make it work. Pricing details were not disclosed. Besides the three main charging networks, two automakers are also founding members of ROEV: BMW and Nissan. ROEV says that Audi and Honda have also have already joined the Association and the organization wants to pull in all EV stakeholders to make electric vehicle charging easy. Fans of EV technology will note that ROEV has nothing to do with promoting either the CHAdeMO or the SAE Combo (CCS) fast charging standard. The Leaf is a CHAdeMO car while the i3 uses CCS, for example. The charging networks, of course, provide both kinds of plugs and don't promote one over the other. Tesla and its Supercharger network are not involved in ROEV, but Tesla drivers can, of course, participate in ROEV.
