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 i5 could be a new kind of i PHEV

Just this month BMW North America CEO Ludwig Willisch made a point of saying "Not any time soon" to AutoblogGreen's question about the arrival of a BMW i5 - and that came after he clarified, in case we didn't know it, that no such model exists. But the rumors of its eventual appearance were swelled again by a report in Autobild that sticks more details and numbers on what could be the next offering in for the i brand. In February, Car magazine laid the i5 out as having a 245-horsepower four-cylinder engine in front, assisted by a 204-hp e-motor in the bow and a 90-hp e-motor in the stern, for about 544 total horsepower. Autobild claims the gas engine will have 218 hp, the front e-motor will have 150 hp and the rear will have 272 hp, for roughly 640 total horsepower. Where the two reports agree is that it - maybe called i5, maybe i7 - will be based on the China-market long-wheelbase 5 Series platform, it will incorporate cues from both the 7 Series and 6 Series Gran Coupe, and it will not be cheap: 100,000 euros ($105,686 US) is the estimate. The i8 starts at 130,000 euros in Germany. Weight for the i5 is figured to be around 3,300 pounds. Green Car Reports says what's important about the i5's drivetrain is that it's being maximized for electric running. Its evolution of the company's eDrive mechanicals will crank the ICE over only above 36 miles per hour, and even then, only in cases of "maximum power demand." Electric-only driving would offer a range of 78 miles, company officials suggesting that it could remain in that mode for "fully two-thirds of its usage cycle." Whenever a vehicle like this arrives, that is, which Autobild says could be in 2019.

Behind the Scenes of BMW's 'Drift Mob,' Part 2 [w/video]

After spending four days practicing about a dozen drift stunt moves in a parking lot for an upcoming BMW "Drift Mob" internet mini-film, Rhys Millen, Sam Hübinette, Dai Yoshihara, Rich Rutherford, and Conrad Grunewald are finally ready for show time. We are brought to the huge urban traffic circle to see the stunts performed midway through the day to observe for a couple of hours.
The undertaking is massive, with multiple cameras set up, scores of crew members, a helicopter filming from above, a rigged pickup for car-to-car shots, sidewalks lined with security and plenty of curious onlookers, and oh, yeah, a major intersection of a top world city shut down for an entire weekend.
The five drifting legends are nestled in their identical red BMW M235i coupes, which have been modified with special handbrakes but essentially nothing else you can't get on a stock version, and are listening to direction from director Mic Rodgers and stunt coordinator Riley Harper. We're basically given free rein of the set, to shoot the cars, the drivers, and at one point, even hopping in with Yoshihara for one of the admittedly more tame stunts. Even then, the g-forces are so severe that they flip our cameraphone's video recording from landscape mode to portrait. Yes, this is a pretty cool day to be reporting on cars, and as we said during our first installment of our behind the scenes coverage of Drift Mob, we're honored to be the only US media outlet here to tell the tale.
