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.

Formula E gets wireless-charging BMW i8 safety car [w/video]

Racing series typically select a safety car appropriate to the kinds of racecars for which they'll be setting the pace. So you might find a Mercedes SLS pacing a Formula One grand prix, for example, and you're more likely to find a BMW M4 on duty at a DTM race and a Chevy Camaro or SS on an oval speedway for a NASCAR or Indy race. It would only stand to reason, then, that the FIA Formula E Championship kicking off next month in Beijing would press a plug-in into service as its safety car. But the organizers didn't go for your run-of-the-mill Nissan Leaf or Toyota Prius.
No, the safety car for Formula E will be a BMW i8 specially modified for the occasion. As you can see from the video below, the hybrid sports car packs a full roll cage, racing buckets with harnesses, special communications systems and on-board fire extinguishers. But that's not all.
In partnership with technological partner Qualcomm, the Formula E support fleet - including two examples each of the i8 and i3 - will feature inductive charging. So while one is out on the track, or at least sitting at the end of the pit lane waiting to be deployed - the other will be charging wirelessly. The vehicles are still pending FIA approval, and only one has been outfitted with the Qualcomm Halo wireless charging system (with the others to be retrofitted later), but they were all on hand for the recent practice race at Donnington Park.

Watch two championship-winning DTM cars from BMW go head-to-head

BMW recently had a little fun with two of the company's past DTM champions. Roberto Ravaglia and Bruno Spengler, winners of the 1989 and 2012 championships, respectively, both showed up at the world-famous Hockenheimring with their title-winning cars. The two swapped seats, with Ravaglia taking the helm of Spengler's BMW M3 DTM racer and Spengler sliding behind the wheel of Ravaglia's first-generation M3 racer in the classic BMW Bank livery, and headed for the track. Spengler got a 23 second head start in the first-gen M3 with Ravaglia chasing behind.
It didn't take long for the older hotshoe to sort out his new ride and close the gap. The short clip below follows the two as they make their way around the circuit, but the really interesting portion comes when the pair begin discussing what they like and don't like about each other's machines. You can check out the full video below for yourself.
