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.

Even 'Ring taxi drivers need to respect the Green Hell

The Nürburgring Nordschleife has the reputation as one of the most difficult tracks in the world to master - deservedly so. With 14 miles of roadway and about 160 corners over a massive amount of elevation change, the amount of grip can change from turn to turn. As the driver of the famous BMW Ring Taxi learned this weekend after a shunt into the barricades, the 'Ring can bite unsuspecting pros just as easily as amateurs.
The video of the incident below shows the M5 oversteering right into the wall as a phalanx of Porsche models arrive behind it. According to Bridge to Gantry, a website that specializes in news about the 'Ring, the taxi's passengers were picked up by another Ring Taxi and driven off with a fantastic story to tell their friends back home. "The accident happened at low speed, there were two passengers in the car, but no one had at any injuries," said BMW spokesperson Cypselus von Frankenberg to Autoblog via email.
The crash also closed track for over an hour to clean up and to haul the stricken BMW away. When a driver making a living from driving lap after lap at the Nordschleife has a crash even as seemingly minor as this one, it just goes to show why the course has the nickname 'The Green Hell.'

1972 BMW 1602e EV concept looks glorious

Pretty sweet. That's a first impression of one cherry-looking experimental electric vehicle from BMW from way back in the day. Or at least from someone who for a time drove a '74 2002. A gas-powered one, that is. BMW built two experimental vehicles in 1972 based off of the old 1600 (which evolved into the 2002) model and even showed them off during the Munich Olympic Games of that year. BMW strung together a dozen typical car batteries and linked them to an electric motor made by Bosch. The result was a battery pack that weighed about 770 pounds (A quick modern-day comparison: a Nissan Leaf battery pack weighs about 480 pounds). Bimmer recently posted a two-and-a-half minute video about the project. The clip doesn't say how far those cars could go on a single charge, but did use to the vehicles to "escort" long-distance running competitions at the Munich Games, since there was no exhaust to choke those athletes out. The timing is fortuitous, of course, as the German automaker looks to continue to gain more goodwill from the green-car set through its new "i" sub-brand of plug-in vehicles, including the i3 electric vehicle and the i8 plug-in hybrid.
