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 brings first diesel 7 Series to US with $82,500* 740Ld xDrive

After almost 40 years on the market, there are probably few things the BMW 7 Series hasn't offered, but when it comes to the US market, one of those things just happens to be a diesel engine. That is all about to change, however, as BMW announced that it will unveil the 2014 740Ld xDrive at the Chicago Auto Show before sales commence later in the spring.
Offered only on long-wheelbase models with standard all-wheel drive, the new diesel 7 is powered by BMW's 3.0-liter inline-six producing 255 horsepower and a stout 413 pound-feet of torque peaking between 1,500 and 3,000 rpm. While BMW has yet to release any type of fuel economy figures, it did say that its diesel technology is usually good for an improvement of 25 to 30 percent over the gas models - just for fun, that means that the 740 Ld xDrive could get as much as 24.7 miles per gallon in the city and 36.4 mpg on the highway, but that's just doing the math and there is nothing official behind those numbers. Acceleration will take a little longer than in the 740Li xDrive (shown above) with BMW stating 6.1 seconds from 0-60 compared to 5.4 seconds for the gas model.
Another small increase over the gas version will be in price, with the 740Ld xDrive getting a starting MSRP of $82,500 (*not including $925 for destination), which is just a $1,500 bump over the 740Li xDrive. For comparison, the Audi A8L TDI starts at $78,800, while the previous-gen Mercedes S350 Bluetec was priced at $93,000. Scroll down for more info on the new diesel-powered 7 Series, and stay tuned to our live coverage from Chicago in a couple weeks as we'll have live images and hopefully more info.

BMW M235i Racing takes to the track

Last month, BMW showed off a motorsports version of its new 2 Series Coupe called the M235i Racing. While that single image was obviously a rendering or design model, BMW Motorsports has now released a video showing the real deal being tested.
From what we can tell from beneath the camouflage, the wide-body fenders ­- to accommodate a 3.5-inch track stretch - are slightly different than the image BMW previously released. Still, the body is noticeably different from the stock coupe. The video, which is posted below, shows glimpses of the race-prepped interior, including a full FIA roll cage, but more importantly we get to hear the 333-horsepower engine and its throaty exhaust in action.
