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.

2014 BMW Z4 sDrive35is

The BMW Z3/Z4 roadster has never really had a widespread following because it has either been too humble and small a roadster (albeit with some fun and very low-volume M editions) or it has been - in this E89 generation - too casual an image leader with no racier aspirations. The current 480-hp Z4 GTEs don't count, since they are as stock a Z4 as today's Pamela Anderson is the same blonde actress we knew as Heidi on Home Improvement. You know, sort of like those ever-so-slightly modified Toyota Camry coupes competing in NASCAR.
The ultimate highpoint for the BMW Z roadster franchise was at the very start of its life in the mid-90s, in the James Bond film GoldenEye with Pierce Brosnan. The Stinger missiles that Q's team installed behind the Z3's headlights were never fired, and BMW never even offered this self-defense package as an option. Yet another case of the ol' bait and switch.
And in all these subsequent years of Z3s and Z4s strutting their long-hooded stuff, the little sporting Bimmer could really have used a live Stinger missile or two to spice things up. The current Z4 exists, it is pretty dang sexy, and BMW seems content to let it linger there. We just drove the new midlife version of the roadster near BMW headquarters in Munich, and it served to reinforce our feelings.

First BMW i8 in US sells for $825,000

Here are some numbers. The standard BMW i8 starts at starts at $135,700. The first i8 in the US was auctioned off at the Pebble Beach Concours d'Elegance this past weekend and the auctioneers, Gooding & Company, said before the gavel was lifted the fist time that they expected the i8 with unique Frozen Grey Metallic and other upgrades to raise between $150,000 and $200,000 for the Pebble Beach Company Foundation. Turns out, the car eventually sold for $825,000 to an unnamed buyer. Along with the honor of having the first i8 on these shores, the special plug-in hybrid comes with Dalbergia Brown leather upholstery, a set of Louis Vuitton luggage and something called a "professional edition" charging station along with laser headlights (subject to regulator approval). A number of other i8s were delivered to a few wealthy car shoppers who managed to make their way to Pebble Beach over the weekend, including automotive guru Roger Penske and Nest CEO Tony Fadell. The special edition was presented at the auction by Jay Leno and BMW North America president and CEO, Ludwig Willisch. You can't put a price on that. Just kidding. You can, and it's apparently $825,000.
