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.

Audi leading rival BMW in worldwide luxury sales race

If you thought competition among the German luxury automakers was hot before, it looks like things are just getting started. For the first two months of the year, Audi has sold more cars than BMW worldwide by just 383 cars.
Audi claims to have sold 242,400 vehicles through February, up 9.3 percent from last year, compared to 242,017 units from BMW, up 8.9 percent, in the same period. While the advantage is tiny, its implications could be huge because Bimmer has been the leader in the premium car segment for the last nine consecutive years. Mercedes-Benz lags behind them somewhat at 229,630 vehicles through February. According to Bloomberg, at this time last year Audi had sold 429 fewer cars than BMW.
The growth is all part of Volkswagen Group's goal to become the world's largest automaker. It currently ranks in second when its heavy truck businesses are considered. The German automotive giant also wants to be the world's leading premium carmaker. "Competition in the premium segment is more intense than ever," said Audi CEO Rupert Stadler to Bloomberg.

2014 BMW 4 Series drops its top, priced from $48,750*

BMW will debut its new 2014 4 Series Convertible at the Los Angeles Auto Show in November, and after seeing plenty of spy shots and, most recently, some leaked images, we now have all the official details. To no one's surprise, the 4 Series convertible is, essentially, a topless version of BMW's new-for-2014 4 Series coupe, and will be offered in the United States in the same 428i and 435i guises.
On the base end, that means the 428i Convertible arrives with the company's 2.0-liter turbocharged inline four-cylinder engine, good for 240 horsepower and 255 pound-feet of torque, and available with either rear- or all-wheel drive. BMW says the 428i will sprint to 60 miles per hour in a respectable 6.2 seconds. For folks in need of more thrust, BMW will happily sell you a 435i Convertible, available only with rear-wheel drive, powered by a 3.0-liter, twin-turbocharged inline-six that produces 300 hp and 300 lb-ft of twist. Hitting 60 mph in the 435i will take roughly five and a half seconds with the standard eight-speed auto. Curiously, BMW did not mention anything about a six-speed manual transmission for either model, so looks like this droptop might be an auto-only affair. We've contacted BMW for confirmation, so we'll keep you posted.
Like the 3 Series Convertible it replaces, the 4 Series uses a three-piece folding hardtop configuration, and BMW says that added sound deadening reduces audible wind noise by about two decibels. Folding the automatic roof takes just 20 seconds, and can be done at speeds up to roughly 11 mph. For chilly, top-down driving (something we're big fans of), there are now three-temperature neck warmers for the front seats - just like what Mercedes-Benz offers with its AirScarf system.
