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.

BMW i8's three-cylinder sounds like it's shaping up quite nicely

We've run across some rather interesting news... or perhaps we should say interesting sounds. The folks from Bimmerpost have scrounged up a short video showing a preproduction BMW i8 running through a few gears in Sport mode at a quick pace, and if you were concerned that the somewhat eco-friendly nature of the upcoming German sports car would neuter its ability to stir the aural senses, fret not.
Judging by the lovely noise coming from the engine compartment of the i8 in the video, BMW's expertise in tuning high-strung, small-bore engines - remember, BMW Motorrad has quite the penchant for well-conceived motorcycle engines - has come through loud and clear. Now, it's worth mentioning that BMW's controversial Active Sound technology will be included with the i8, so the production car may not sound exactly like this version, which is running with the tech disabled. Owners won't have the ability to disable Active Sound on production i8s.
In related news, Bimmerpost reports that BMW will equip the i8 with an external Active Sound Design system to go along with its Pedestrian Protection System. That means those on the outside will likely hear piped engine recordings from the rear and a sort of "howl" from the front in order to warn pedestrians that the otherwise quiet (when running on electricity, that is) car is approaching. It will also feature technology that can stop the car before contacting a pedestrian.

2015 BMW Alpina B6 Gran Coupe challenges the M6 in New York

Despite being a well-respected outfit for decades, Alpina remains something of a mystery to many stateside BMW fans. In Europe, Alpina has established itself as a first-rate source for breathed-upon high-performance Bimmers, and it's looking to continue picking up traction on our shores. The US has received a handful of Alpina models through BMW factory channels, namely the 7-Series-based B7, and now we're getting another fast four-door with the debut of the BMW Alpina B6 xDrive Gran Coupe at today's 2014 New York Auto Show.
The B6 Gran Coupe stands as an interesting sibling to the factory's M6 Grand Coupe. Both are propelled by a 4.4-liter twin-turbo V8, but the tunes are quite different. The Alpina produces 540 horsepower and 540 pound-feet of torque, which is 20 hp less than the M6, but with 40 lb-ft more torque. An eight-speed automatic and all-wheel drive mean that the B6 is about half a second quicker to 60 miles per hour than BMW's own creation. Plus, the B6 has an unrestricted top speed of 198 mph, making it one seriously rapid 6 Series Gran Coupe.
The sport sedan also wears other Alpina goodies like 20-inch versions of the brand's 21-spoke wheels and exclusive color options. The B6 Gran Coupe goes for $118,225 (including destination), and will be available through BMW dealers immediately after the auto show ends. More info about the B6 is in the release below.
