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: i8 sold out, i3 records 10k orders

Just in case anyone was wondering how plug-in BMW cars would be received, the answer is apparently "quite well." After speaking with BMW's global sales chief last week at the LA Auto Show, Reuters has learned that the plug-in hybrid i8 sports coupe is already sold out for its first year on the market.
There is no word as to how many i8s BMW sold, but the first example was delivered to a customer last week in Germany. As for the all-electric/range-extended i3 hatchback, the automaker has received more than 10,000 orders for this model before it even goes on sale. Likewise, we don't know how many BMW plans to sell, but we do know they'll be showing up in the US before next summer.
We've already spent some time behind the wheel of both plug-in BMWs, and you can check out our first drive of the production i3 and our first drive of an i8 prototype.

BMW M6 amped up for track duty by Risden

Risden Engineering is a bit of an unknown, if we're being completely honest - we have yet to report on the company to date, and its corporate website is really an information desert save for the name and a few email addresses. Even the press release that we requested from Risden's contact person is short and vague. That's all pretty much okay with us as long as the shadowy tuners, you know, make good on this sweet-looking BMW M6 racecar thing.
Dubbed the Risden 6R, we're told that the M6 modification will result in a vehicle that is more adept at track work, while still being street-legal. In terms of specifics, we read that a full aero kit will be involved, with one fixed and one retractable rear wing (hard to miss). There are obviously new wheels, and the company has also added a fully adjustable suspension, a four-point roll bar and a new braking system - all while reducing curb weight overall.
Apparently more details are to follow after the 6R's official release in the first quarter of 2013. We wait with bated breath.
