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 reveals X4 M40i performance crossover

The first details and images of the new BMW X4 M40i leaked out Tuesday, and now the Bavarian automaker has released all of the information on its new performance crossover. The latest model in BMW's M Performance line offers an array of upgrades over the existing X4, and they start under the hood. That's where Munich fitted a new 3.0-liter turbocharged inline six based on the one found in the X4 xDrive35i (whose place this model takes at the top of the X4 lineup). The engine is tuned to deliver 355 horsepower and 343 pound-feet of torque. In addition to the twin-scroll turbocharger, the engine also boasts variable cams and valves, as well as a high-precision injection system. This translates to a 0-60 time of 4.7 seconds – a figure which BMW cites as "best-in-class." Power is channeled to all four corners through an eight-speed automatic transmission and a re-calibrated xDrive system that's biased to the rear wheels. Naturally the suspension has been upgraded as well, with increased camber, stiffer springs, reinforced stabilizers front and rear, and active dampers. The steering rack has also been retuned. You'll be able to tell the M40i model from lesser X4s by its enhanced appearance. Though the aero kit looks largely the same as the stock version, BMW has fitted the M Performance model with metallic accents, 19- (or available 20-) inch alloys wearing Michelin Pilot Super Sport rubber, and a variable sport exhaust. Inside, it's also upgraded with a unique steering wheel, shifter, sports seats, and specific badging. This adds up to a crossover that may not be a full-on M model, but promises up the performance quotient significantly over the rest of the X4 line. THE NEW BMW X4 M40i - World premiere of the new inline 6 cylinder TwinPower Turbo engine. - Intelligent BMW xDrive: four-wheel drive with rear-wheel-drive characteristics. - A sporty chassis specifically tuned to M Performance specifications. Woodcliff Lake, N.J.- September 30, 2015... Today, with the introduction of the new BMW X4 M40i, the successful BMW X4 has gained a new top model.

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.
