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 dishes on 'lightweight' 2014 M4

BMW's M cars are not what we'd call featherweights. Sure, the big, bruising twin-turbocharged V8s deliver a lot of power, but the fact of the matter is that more weight often equates to less fun.
Which is why we're so excited over a recent sit-down the blokes at Top Gear had with BMW's product manager for small and medium cars, Matt Collins. The chat led to talk of the M3 Coupe replacing M4. Collins confirmed that, yes, the new M4 would be turbocharged. The new engine will also be a six-cylinder, which should make purists happy.

BMW reveals i8 Concours d'Elegance Edition ahead of Pebble Beach

If you want to be among the first owners in the United States of the new BMW i8, the Pebble Beach Concours d'Elegance will be the place to be next Saturday. That's where Gooding & Company will auction off this one-of-a-kind hybrid supercar.
The BMW i8 Concours d'Elegance Edition was previously slated to be the very first i8 in North America, but has now apparently been downgraded to the guarantee of being among the firsts. In any event, it packs a series of special touches to make it unique. For starters, it's decked out in matte grey with unique brown leather upholstery, blue accents and Pure Impulse Tera World trim, with BMW i8 logos embossed into the headrests, special treat plates and the signatures of several key BMW personnel on the rear parcel shelf.
Pending government approval, it's set to be the first vehicle in the US fitted with laser headlights, and comes equipped with a special key, Louis Vuitton luggage and a "professional edition" BMW Charging Station. Scope out all the details in the press release below and take a closer look in the gallery above.
