Watch the BMW i8 get wrung out on the Ring

Been wondering where the heck the reviews of the all-new, plug-in-hybrid BMW i8 have been? After all, the car isn't exactly new, having debuted in concept form way back in September of 2009. In August of last year, we even tested a prototype of the new supercar. Despite that, though, we still haven't gotten a crack at the actual vehicle that will be sold to the public.
Well, we're happy to tell you that we're currently testing the i8 and will have a proper review for you soon. If, however, you're just aching for some coverage of the low-slung plug-in, we have a short video of it in action around Germany's famed Nürburgring.
Despite it's three-cylinder, turbocharged gas engine, the i8 sounds pretty angry as it laps the Ring. That is, until it has a little bit of a breakdown. According to the guys that caught the car on video, it appeared the i8 had a minor brake issue, and was parked on the side of the track for a good 15 minutes, with the driver pumping the brakes. We should probably just take this as proof, then, that manufacturers are actually using the Ring for testing, and not just messing about.

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.
