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.

Hamann M6 Gran Coupe is all flared and shiny

Oh, Hamann. After rolling out the ridiculously pink Mystère at this year's Geneva Motor Show, the tuning company has worked its mirror-finishing magic on the BMW M6 Gran Coupe, debuting this, the aptly named "Mirror" at the Frankfurt Motor Show. It sure is shiny, and a full 40 millimeters wider than the standard M6 GC.
Hamann says that the, um, "tailor-made suit" exterior treatment is made up of a new front bumper spoiler with large air intakes, side skirts, a new rear spoiler, and wing extensions out back. And the end result is... well, let's just call it noticeable. The special BMW rides on unique 21-inch wheels and sits a full 25 millimeters closer to the ground, as well.
As far as we can tell, Hamann hasn't upgraded the M6's 4.4-liter twin-turbo V8 at all, though there's a new sport exhaust system that "depending on the application area, either noisily announce its presence or purr sportily." Sounds like it's as loud as its newfound appearance.

Behind the scenes of BMW's 'Driftmob' [w/videos]

All this, for one minute and 47 seconds of action-packed footage with no official plot.
We arrive in Cape Town, South Africa, on the third and final practice day for the drivers of a BMWStories internet video called The Epic Driftmob feat. BMW M235i. We are immediately whisked to a large, empty parking lot on the outskirts of Cape Town, where tires are squealing and chunks of rubber are flying as five red BMW M235i coupes churn up more smoke than a California wildfire. And the smell - it smells like heated metal, the kind of thing rev limiters are made for. Times five.
