Recharge Wrap-up: E15 could help smog woes, MPG average at all-time high

A new study shows that using an E15 blend instead of regular gasoline would reduce smog in Chicago. Increasing the availability of the 15-percent ethanol blend could help reduce carcinogenic air pollution and improve air quality, particularly on the city's South Side. The study found that E15 reduces the risk of cancer by 6.6 percent. It also reduces greenhouse gas emissions 1.5 percent compared to a 10-percent ethanol blend. Read more at Domestic Fuel.

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.

2014 BMW X5 recalled over faulty child-safety locks

BMW is set to recall some 6,400 of its new-for-2014 X5 SUVs built between December 12, 2013 and March 10, 2014 due to concerns that the child safety locks, if set, might deactivate without warning. The problem affects only those vehicles with the automatic soft-closing option.
According to the bulletin issued by the National Highway Traffic Safety Administration, the lock mechanism on the rear doors "may not have been manufactured to correct tolerances," meaning the safety locks could disengage with a simple pull of the door handle. Basically, with a pair of tugs, the rear doors could be opened from the inside, regardless of child safety locks.
BMW is in the process of notifying owners of affected vehicles. Any necessary repairs will be conducted free of charge. Take a look below for the official press release from NHTSA.
