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 offering glitch fix for i3 with range extender

The BMW i3 has received quite a bit of acclaim since its release, with the electric powertrain grabbing a spot on Ward's 10 Best Engines list and the high-tech machine earning the nod as 2015 Green Car of the Year. However, Consumer Reports uncovered a vexing problem with the range-extended version of the hatchback that has plagued it until a recent software update. While CR was driving the range-extended i3 last year, it discovered that when the internal combustion engine was running during low states of charge, hard acceleration could suddenly cut back with no warning to the driver. This was especially problematic when passing. BMW knew about the issue and promised a software update in the spring. That improvement is now available. BMW spokesperson David Buchko tells Autoblog that the software update adds a percent-of-charge indicator to all models of the i3 to let drivers know just how much juice is left. For the range-extended model, it also provides a warning of possible power reduction when the charge reaches two percent. According to Consumer Reports, the revision lets the car anticipate needing more reserve power based on the topography from the navigation system, as well. For any i3 drivers who want the upgrade, they need to visit a dealer for installation, according to Buchko, but it should be come at no cost to owners. Related Video:

Consumer Reports' first motorcycle reliability report finds Japanese brands ahead

Consumer Reports has released its first ever study of motorcycle reliability, and students of its ratings on cars might notice a suspicious similarity - Japanese brands require fewer repairs than the leading American or German brands.
The study analyzed the reliability of 4,680 bikes owned by CR subscribers and found that Yamaha had the best ratings, with just one in ten bikes built between 2009 and 2012 requiring a repair over a four-year period. The makers of the R1 and R6 sport bikes were closely followed by Kawasaki and Honda, while one out of every four of the rumbling bikes from Harley-Davidson experienced an issue. BMW had the worst rating of the brands represented, with one in three bikes having problems.
According to CR, neither Suzuki nor Triumph owners provided enough information for a reliable rating. Based on the responses received, though, Suzuki would have finished with the other Japanese brands and Triumph, being English, would have been one of the less reliable makes.
