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 M5 turns 30, celebrates sideways

BMW has a secret, and it's not telling. The brand's M Power blog is celebrating the 30th anniversary of the M5 and is taking a look back at previous models of its Autobahn-storming sedan, but it says that it will end "with a surprise." The celebration kicks off with a short video showing the latest M5 making some smoky donuts.
The original M5 debuted in 1985 and was the company's most expensive model at the time. Still, it packed a 3.5-liter six-cylinder generating a claimed 282 horsepower (286 PS), which was rather potent in its day. The company touted it as the world's fastest production four-door sports sedan at the time.
BMW won't reveal the surprise until it has chronicled all five generations of the M5, but it wouldn't be shocking to see an anniversary edition model appear sometime later this year. Scroll down to check out the video of the muscle sedan celebrating its birthday the only way it knows how.

BMW jazzes up the Z4 with Pure Fusion Design package

While the new M3 sedan and M4 coupe may be the big news, they're not the only things that BMW has in the cooker. The Bavarian automaker has just announced a new special edition that serves to highlight the Z4 roadster.
Called the Pure Fusion Design package, the specially-equipped Z4 incorporates Nappa leather trim in ivory with brown stitching covering the seats, armrests and door panels. The lower dashboard is done up to match in white, with brown-accented black leather upper dash, window sills, sun visors and instrument surround. A brown leather line accents the interior, with Fineline wood trim.
BMW is offering the Z4 Pure Fusion Design in the unique shade of sparkling brown metallic pictured here, along with other available colors, and customers can combine the package with the M Sport pack as well. Scroll down for the full press release.
