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 offering Track Handling Package for 2 Series

After getting a chance to drive the BMW M235i earlier this year, we mentioned our regret at not being able to sample the lighter and less powerful 228i Coupe. We'd like to have seen how close the latter could get to the former, noting that "there's a lot of room for upgrades with the $11,000 retail difference." BMW is closing that performance gap slightly, announcing that a Track Handling Package will join the options sheet for the 2015 228i Coupe.
The group bolts on Variable Sport Steering, Adaptive M Suspension and M Sport Brakes behind new 18-inch lightweight wheels wearing Michelin Pilot Super Sport tires. There's no change to the 240-horsepower four-cylinder, but a coupe so equipped should be able to do plenty more with the horses it has thanks to a faster steering rack, sharper handling due to additional sensors and a ten-millimeter drop in ride height, and larger brakes and discs.
BMW has used the New York Auto Show as a venue to introduce the new Track Handling Package, and it will roll onto showroom floors in July and pricing will be announced sometime between now and then. Takers can get it with both the six-speed manual and eight-speed Sport Automatic, see it in the high-res image gallery above, and read about it in the press release below.

2013 Nissan GT-R and 2013 Alpina B6 mix it up on track and street

Here we have Autocar making an unforeseen comparison: the Nissan GT-R against the Alpina B6 at Brands Hatch and on public roads. Steve Sutcliffe clobbers the circuit in the 3,828-pound, all-wheel-drive sports car, then sees how well the 4,114-pound, rear-wheel drive grand tourer does against it.
Sutcliffe says there are quite a few similarities between the two cars, but that's really only on the spec sheet. The Nissan's got two turbos attached to its 3.8-liter V6, 542 horsepower and 465 pound-feet of torque. The Alpina's got two turbos attached to its 4.4-liter V8, 532 hp and 528 lb-ft. But one's brief is to be a monster on the track, the other on the boulevard, and if there's anything the video demonstrates, it's each car's focus.
