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 X7 rumored to get BMW's best interior, 130,000-euro price

Spanish outlet Motor.es has some info on the coming BMW X7, the sport activity vehicle that will take the Munich brand to the penultimate SUV segment. Unnamed sources said BMW has been working on both the X7 and the future Rolls-Royce all-terrain vehicle for almost two years, and that in BMW guise it will ride on the CLAR (CLuster ARchitecture) platform that will make an appearance later this year under the new 7 Series. The Rolls-Royce, on the other hand, will get its own aluminum spaceframe. The two vehicles will share components, though, which are now being tested. Running gear and engines will borrow from the X5 and X6 tool chests, with rear- and all-wheel-drive configurations mooted and engines ranging from the TwinPower 3.0-liter six-cylinder to an uprated version of the 6.0-liter V12 in the 760iL. The 4.4-liter V8 is mentioned as the middle child and perhaps the base for an X7 M, should one be made. A plug-in hybrid offering could swipe the unit from the X5 xDrive40e PHEV, good for 55MPGe in that current application. The interior, we're told, will be the nicest seen on any BMW, said to surpass that of the new 7 Series. We'll have to wait two years to find out how close all of that is to the mark, but the tidbit that might need some salt sprinkled on it right now is the predicted price: Motor.es says 130,000 euros in Europe, to start. That's not the first time a sky-high price has been predicted, but a leap that far beyond the six-figure mark would readjust all of our expectations for the vehicle when an X5 cost 53,700 euros in France and an X6 costs 70,900 euros. Other outlets predict US pricing to start from around $60,000; the X5 costs $53,900 here, the X6 is $59,600.
