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.

2014 BMW i3

A Purer Than Ever Sort Of Driving Pleasure
This all started back in 2007 when the megacity urbanization trend hit full stride and BMW began brainstorming the 2020 future of mobility. The product was thus originally called the BMW MegaCity vehicle. Then the 'i' division of BMW was officially born in 2011, and we have since been exposed to various "leaked" images and official prototype unveilings of both this i3 and the i8 eco sports car. The latter (called i12 in the halls of Munich) was originally called the Concept Vision Efficient Dynamics and presented as a diesel-hybrid.
The time is now upon us for the market launch of the plug-in i3 (called i01 internally). The wider motoring public already has its opinions and BMW is listening to all of them, so there's a bundle of nerves around these limited drives of the i3 for a select few members of the media, Autoblog included. We came to an airfield outside of Munich and were handed an i3 test car to drive around a set course filled with blue- and white-striped cones. BMW tech experts were everywhere and some of the discussions around the various technical displays even got a little heated.

Are you a BMW M4 GTS track car in disguise?

BMW is always happy to extract a little bit more gumption out of its M cars, just look at the latest 30th anniversary M5 or even the earlier CSL variants of the M3 for proof. Now, It looks like we might be getting the first glimpse of an even hotter M4, and it's wearing very interesting livery.
Our spies recently shot this M4 that could preview a future GTS version. It's all done up in MotoGP decals, but that might just be a ruse. This car sports a camouflaged lower air dam and rear wing, but those parts don't appear to be from an actual series safety car. The chin spoiler seems larger, and the rear wing is completely different. You can also spot an obvious Recaro logo on the driver's seat in one of the photos. Plus, the BMW emblem is removed at the back.
The disguised changes and odd choice of decals make this prototype incredibly weird. A BMW exec said at the beginning of the year that there were "no plans whatsoever to make a lighter, harder version just yet," of the M3 or M4, despite earlier rumors to the contrary. Check out the gallery to see what you think this is.
