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.

Creative minds build lightweight Lambos and Bugattis with cardboard and pedals

As manufacturers continue their quests to reduce the weight of their vehicles, they switch out heavy steel for lighter materials such as aluminum, carbon fiber, titanium, and sometimes even magnesium. But they've been ignoring a cheap alternative that is widely available: cardboard. Leave it to two visionaries from Vietnam to crack the code and build supercars and superbikes out of the versatile paper product. Vietnamese YouTube channel NHET TV, via CarScoops, might only have a year under its belt, but in that short amount of time, it has amassed more than 350,000 subscribers. What initially started out as a random collection of harmless pranks, trolls, and makeshift time-killers has blossomed into an entertaining channel of ultra-low-budget car and motorcycle builds.  The first video posted is a paper plane competition, but the second video shows the first appearance of a vehicle, a Ducati Panigale made out of cardboard and a bicycle. This isn't like Paper Mario with a two-dimensional silhouette, it's a close-enough three-dimensional replica. That project was admittedly pretty rough, but the work has only improved as the channel has matured.  Throughout the past year, NHET TV has stuck with high-performance transportation for inspiration. They've built projects that mimic a Lamborghini Sian, a Lamborghini Aventador SVJ, a Ferrari LaFerrari FXX K, a Bugatti Chiron, a BMW S 1000 RR, and a Yamaha YZF-R6, among others. Some of the builds, such as the Bugatti, go beyond the typical cardboard-body-on-bicycle-frame. As seen in the video below, the NHET TV built a tubular frame for the car using spare bike parts that they welded together. The Bug even has a custom steering column and steering wheel, though the high-quality model continues to use bike chains and pedals for power. The SVJ might be the most advanced vehicle, as it has a real engine for power and has custom reverse gearing. These guys are creating fun out of the limited resources they do have, and that's what right now is all about. Enjoy the videos below and watch more on the full NHET TV channel.
