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 M3 driving off cliff is a chilling PSA

We're a little shocked that the unnamed owner of this cliff-diving E46 BMW M3 would upload the in-car footage of his accident to YouTube. Not only that, he uploaded two videos: raw footage of his roll down the cliff (it looks like somewhere in the Southwest, maybe Arizona) and a tribute video for his BMW that suffered the most severe consequences of understeer. Not only does uploading the videos leave him wide open for judgment by fellow enthusiasts (just read the YouTube comments), but we imagine if the police and his insurance company somehow don't know about the incident already, they will shortly. Scroll below to view for yourself.
The raw footage shows the sort of driving that led to the M3's violent tumble, and it serves as a good public service announcement reminder for everyone out there: Just like the Spengler's streams, double yellow lines aren't meant to be crossed. Also, hard driving is one thing, but hammering on public roads at speeds clearly above your skill levels as a driver is not only a recipe for legal trouble, it's a script for ruining your car at the very least, if not your life.

BMW X3 spied with nip and tuck nearly complete

With the style-driven BMW X4 coming along in development, it looks like some of the forthcoming crossover's design could trickle over to its utilitarian sibling, the X3. Captured in these spy shots, it appears that the 2015 BMW X3 is preparing for a minor facelift, and from what we can tell, the biggest change will center on the CUV's headlights.
There is plenty of camouflage on the front and rear fascias to suggest updates will occur there, too, but we can definitely tell that the X3 will be getting LED-equipped headlights - at least as an option, anyway. The halos are slightly different from the current offering and there is also an LED strip above the headlights used as turn signal indicators. Another interesting thing we notice in these pictures is the nub at the bottom of the grille (also visible in recent X4 spy shots). While this could be some sort of test sensor for this prototype, it could also be a front-mounted camera for a possible parking assist system.
We don't expect any changes to the powertrain and we're not sure what updates could be in store for the interior, but we're guessing that that the 2015 X3 will debut shortly after the X4 goes on sale next year.
