BMW rethinks all-wheel-drive M cars

BMW M hasn't been able to decide whether it wants to jump on the all-wheel-drive bandwagon or not (with the exceptions of the X5 M and the X6 M, which are based on AWD architecture). That might be changing though, since M's president Friedrich Nitschke recently realized that 70 to 80 percent of Mercedes-Benz E63 AMGs are ordered with all-wheel drive. Earlier this year, Nitschke said that there were no new AWD M models planned, so this comes as somewhat of a surprise.
"On our cars we are thinking of all-wheel drive, but it won't come before we get the successor of the M5 and M6," Nitschke said in a Motoring report. "That's the timing and it's not practical to react in the current life cycles."

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.

Rinspeed previews Budii concept ahead of Geneva show

Every year Frank Rinderknecht and his team at Rinspeed come to the Geneva Motor Show with another fantastical concept car, and next year's will be no exception. Though the show may still be several months away, the Swiss outfit is already giving us a glimpse of what to expect. Rinspeed's latest project is called the Budii, and it aims to "redefine the relationship between man and machine." As you might have guessed, that means driverless technology. Specific details at this point are limited, but the design calls for an electric vehicle with an adaptable cabin featuring drive-by-wire steering wheel. That wheel can swing out of the way to the center of the dashboard or to either side, should driver or passenger (as blurred as those rigid concepts become in this case) wish to take control. Beyond that we don't know much at this point, but the image above seems to indicate it'll be based on the BMW i3. Meanwhile the long list of partners and suppliers suggest it'll feature a design by Mansory, a Harman infotainment system and a Carl F. Bucherer analog clock embedded in the dynamic dashboard. 2015 Geneva Motor Show Rinspeed exhibits "Budii" at the 2015 Geneva Motor Show: "We need to redefine the relationship between man and machine" As far as Swiss automotive visionary Frank M. Rinderknecht is concerned, the breakneck speed of technical developments forces us to redefine our relationship with the automobile. The farsighted Swiss says: "Until now, what we have primarily associated with auto mobility was freedom and individuality. And - consciously or unconsciously - we are prepared to pay a high price in many regards for these privileges. We need only look at the accident statistics." Autonomous driving undoubtedly offers the opportunity to drastically diminish some of the drawbacks of private transport. For example, the number of traffic accidents could drop worldwide. But although it will be less prone to err than humans, even the best technology will not be perfect. "That is something we will have to accept," believes the boss of Rinspeed, the Swiss automotive powerhouse of ideas.
