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 says yes to 1 Series M successor, no to M6 Gran Coupe with xDrive

If you're anything like us, the first half of that headline made you smile. The BMW 1 Series M Coupe was, without a doubt, one of our favorite cars from the past few years, and according to a BMW Blog interview, Dr. Friedrich Nitschke, head of the company's M division, has confirmed that a successor is in the works.
"We haven't made a decision yet, but the 1M coupe was so successful, that in my opinion, I am absolutely sure we will build a successor," Nitschke told BMW Blog. Currently, BMW only offers the M135i version of the new 1 Series hatch in Europe, which Nitschke says is "not a pure M car."
Moving elsewhere in the M range, BMW Blog asked about the M6 Gran Coupe that recently debuted at this year's Detroit Auto Show. The obvious competitors for this car will be higher-power versions of the Porsche Panamera and Audi RS7, but while both of those offer all-wheel drive, the M6 only sends power to its rear wheels.

BMW X4 reclaims dash of utility with Clemson student project [w/videos]

BMW seems willing to exploit every automotive niche it can find with creations like the four-door, 'crossover coupe' X4 and X6. Of course, these designs come with a compromise. That svelte fastback means that they just can't haul as much cargo as a more traditional, boxier hatchback. Fortunately, students at Clemson University's International Center for Automotive Research might have a novel solution: the engineering graduate program has turned the crossover into a unique pickup.
Dubbed Deep Orange 4 concept, this functional prototype has an enclosed cargo area with a sliding glass panel that opens up to expose a pickup bed if more room is needed. Think of it as the GMC Envoy XUV of German crossovers. This isn't just an X4 with its roof hacked off, though. The students actually started with an X3 and grafted on this top later in addition to the two barn doors for access to the bed.
To make this project even more impressive, this pickup-crossover could conceivably be produced. The graduate students conducted an in-plant analysis of BMW's manufacturing abilities and went back to the university to create a plan for a low-volume vehicle that could actually be built. "The students working on this phase of the project did an excellent job of keeping costs down while finding optimal integration opportunities," said Rich Morris, vice president of assembly at BMW Manufacturing, in the university's release.
