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.

2015 BMW X4 is a budget X6

We won't argue that crossovers are hugely successful vehicles, with automakers working to provide functional CUVs in a wide range of sizes. But over at BMW, things are just getting out of hand, as evidenced by this new X4 "Sports Activity Coupe" that debuts here at the 2014 New York Auto Show.
BMW is seeing fit to offer vehicles in even the most niche of niches, and the X4 is no exception. Want proof? Have a look at the X4, and the compare it to the X3, the 3 Series Gran Turismo, the 3 Series Sport Wagon, and the 4 Series Gran Coupe. Aside from marginal differences in things like ground clearance and the exact slope of the hatchback, what, exactly, is the difference?
Like the other models we just mentioned, the X4 is powered by either a 2.0-liter turbo-four with 240 horsepower or a more powerful, 3.0-liter turbo-six with 300 horsepower, and unsurprisingly, power is sent to the ground exclusively via the company's xDrive all-wheel-drive system. An eight-speed automatic transmission is the sole gearbox available with either engine. All sounds very familiar, right?

This is the BMW Z4 GTE that will wear the Roundel in ALMS

The Speedweeks at Daytona International Speedway are a month of racing and reveals, with the season's metal going for the flag at races like the Rolex 24 at Daytona and other cars being introduced to the public. In the latter category is the BMW Z4 GTE (click the image above to enlarge) joining the American Le Mans Series GT class this year with BMW Team RLL (Rahal, Letterman and Lanigan). This machine replaces the M3 GT that completed four years of service and won the class title in 2010 and 2011. Naturally, the team is tempering expectations for the Z4 GTE by repeating the fact that it sees this season as a development year.
BMW Team RLL drivers for its two cars will be Bill Auberlen and series rookie Maxime Martin in the No. 55, aided by Jörg Müller for the endurance races at Sebring and Road Atlanta. The No. 56 car gets Dirk Müller on a full-time basis, Joey Hand when he's not competing in the DTM series, and John Edwards when Hand isn't available. Uwe Alzen will help out with driving duties in the No. 56 at endurance races.
