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's next-century concept mentions no powertrain, and we're sad

So the Ultimate Driving Machine might soon become the Ultimate Machine Driver. We get it, that's the way things are moving. For its part, BMW still plans to involve a driver in its next-century designs, as foretold by the Vision Next 100 concept it unveiled at its centenary celebration kickoff event. But what gets us is that BMW, Bayerische Motoren Werke, the company known for delivering some of the most sorted powertrains – gasoline and otherwise – over the last century makes no mention of the future of propulsion when presenting its idea of the next 100 years on the road. Maybe it's the fact we just don't know what will power our cars even 10 years down the line; locking into one concept or another could look bad in hindsight. But the whole, er, concept of a concept is to look at what might be possible, not avoid sticky issues. Where are the in-hub motors, the wireless charging mats, the onboard fusion reactors we were promised in Back to the Future Part II? This is an opportunity to offer innovative solutions. Skipping over the power was a mistake, and one that makes me a little disappointed in the company. I'd have liked to see BMW go big with a bold prediction, or even just admit that gas will be gone and some form of electrification will take its place by 2116. We're okay with electric motors as long as they don't drain the life out of cars, and they don't have to, which is something companies like Tesla and even BMW have proven. Here's hoping one of BMW's other centenary concepts will pick up where the Vision Next 100 fell short.

2015 BMW 228i Convertible

BMW history is littered with small, four-seater convertibles that offer style, spirited performance and driving flexibility. These days it's the 2 Series range, not the 1 or the 3, that carries on the droptop-driver's-car tradition, and the 2015 228i Convertible will the first flavor of it to hit US shores. With prices starting in the upper $30k range, conservative but attractive exterior styling and just enough interior comforts and amenities to feel like a true-luxury player, the 228i makes a strong initial case for itself as either a first or second vehicle. Concurrent with my First Drive of the 2015 BMW X6 M, the Germans brought along their new 2 for testing along some pretty mellow Texas driving routes outside of Austin. With roads that ranged from sweeping country lanes to small town streets, and weather changing handily from cold and misty to bright and warm, I got a good sample of what the new open-top 2 can do. Drive Notes I'll admit to getting behind the wheel of the 228i convertible with a bit of a bias: the old 1 Series line, including the droptop, was amongst my favorite BMW models in years. In terms of overall character, this 2 Series has mellowed a lot versus the chuckable, cheerful 1er. The steering response isn't quite so whip-fast, and the longer wheelbase means it's less willing to rotate overall. Of course, the 2, especially in convertible form, does feel better suited for the stereotypical small, premium convertible driver, too. Ride quality over our mostly smooth-road drive route was placid and controlled, and steering still felt steady and weighty on center and with lock added in. The car also offers really well-sorted protection from wind buffeting and noise, both with the top raised and lowered. I drove topless on the highway and on surface streets, and was impressed at how cozy I felt with the wind deflector erected and the windows up. Cold-weather convertiblers should do well with this BMW (especially when the xDrive AWD car launches, later in the year). Erect the folding soft top – a feature that's available at speeds up to 30 miles per hour – and the NVH experience is transformed. BMW says that the top-up wind noise has been reduced "by half" versus the 1 Series – a fact that I had no trouble believing after the first few seconds. Wind rush is basically eliminated with the roof raised, and the car becomes a downright conversational space thusly set up.
