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.

134K BMW 5 Series recalled for taillight issue

BMW is voluntarily recalling 134,100 cars due to a faulty ground terminal in the taillight bulb carriers, causing the sudden failure of brake lights, turn signals and reverse lights. The recall covers 2008 through 2010 5 Series models produced between March 1, 2007 and December 31, 2009, and includes everything from the 528i to the mighty, V10-powered M5. It's unclear if this recall is limited to sedans or extends to the 5-Series Touring.
There have been no reported cases of injuries, fatalities or crashes associated with the taillight issue. BMW will be issuing recall notices to affected owners in the coming weeks, asking them to report to dealers so that the bulb carriers on the taillights can be replaced. All repairs are, naturally, free of charge. Scroll down for the official recall notice from the National Highway Traffic Safety Administration.

BMW to follow Honda back into F1?

The economic downturn wrought devastating effects on motor racing. Formula One alone lost half its engine suppliers when Honda left at the end of the 2008 season, and both BMW and Toyota followed at the end of 2009. But things are looking up again. Cosworth may have dropped out this season, reducing the engine suppliers to three: Ferrari, Renault and Mercedes, the latter of which admits that it may have left had the engine formula not changed. But Mercedes has stayed and is dominating the championship. Honda is coming back next season. And word around the paddock is it may not be the only one.
According to Giancarlo Minardi - founder of the team now known as Scuderia Toro Rosso - BMW engineers have been conspicuously spotted lately at F1 test sessions and grands prix, lending to speculation that the new engine regulations may entice the Bavarian automaker back into the series. According to Minardi, BMW's marketing division is pushing for the automaker's return to F1, with the board slated to make a decision in May. BMW would be more likely to consider an engine-supply deal rather than taking a team over like it had with Sauber, but with which team or teams it might collaborate remains a big question mark at this point.
As if that's not enough, Ford is said to be considering taking over Cosworth's aborted V6 turbo engine program to take both outfits back into the sport as well. Cosworth supplied F1 engines under the Ford banner for years, but returned under its own name for four seasons from 2010 through 2013 before shuttering its program to develop an engine to meet the new regulations adopted this season.
