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.

More details emerge on hotter BMW i8S coming next year

The BMW i8 recently won the Autoblog Technology of the Year award, and it's going to get even better. In October, Automobile magazine reported that BMW's i brand is working on an i8S that would be stiffer and more powerful, and celebrate the marque's centenary in 2016. At the time, one of two power unit combinations was suggested, either one of them good for more than 500 horsepower. Car magazine has added more info on the coupe said to be called Project M100, saying that in addition to being a birthday gift for BMW, it will also be a going-away statement to current chairman Norbert Reithofer, who is expected to retire in 2016 or 2017. It will also be so thoroughly reworked that there will be plenty of daylight between it and the standard i8: a more integrated carbon fiber and aluminum chassis, a wider range of materials used in the build, a larger luggage bay due to the omission of rear seats, a more aggressive suspension supporting heartier brakes and wider tires, and - perhaps - a different aero and ground-effects package to be visually different and make the most of the alterations. As for that power unit, Car says that the two options mentioned by Automobile are still under consideration, being either a 2.0-liter twin-turbo four-cylinder with 320 horsepower and a 204-hp electric motor, or a 3.0-liter straight six with 480 hp and an electric motor with 109 hp. Either choice gets an integrated starter motor good for another 27 hp, and a total torque number of roughly 520 pound-feet, 100 additional lb-ft than the current car. Word is that it will be shown for the centenary in 2016 then go on sale by the end of 2017.

Mercedes chief invites Audi, BMW to compete in F1

Mercedes-Benz didn't just win the Formula One World Championship in 2014 – it positively dominated it. The team won all but three of the grands prix this season, scoring a one-two finish at more than half of them and landing at least one car on the podium at every race without exception. It goes without saying, then, that the German automaker thrives on competition, but now it's welcoming even more. Speaking with Germany's Sport Bild at its homecoming celebration in Stuttgart, Daimler chief Dieter Zetsche welcomed Mercedes' biggest rivals Audi and BMW to join it on the F1 grid. Noting that the three German brands share some 80 percent of the market for luxury automobiles, Zetsche said that F1 would make a natural arena of competition for Mercedes, Audi and BMW to fight for top bragging rights. The three currently compete against each other in front of home audiences in the DTM touring car series – effectively Germany's equivalent to NASCAR – but of the ten races held this year, the majority were in Germany itself, and all of them took place in Europe. BMW last competed in F1 when it bought the Sauber team in 2006, but withdrew from the series in 2009. Despite its progenitor Auto Union having fielded the famous Silver Arrows in pre-war grand prix racing, Audi has never been a player in modern F1 racing, though recent rumors have linked it to a potential foray – spurred by the arrival of sister-company Porsche on its home turf at Le Mans, the departure of several of its key endurance drivers and the hiring of former Scuderia Ferrari chief Stefano Domenicali. Porsche had similarly considered an F1 program before getting the go-ahead to compete with Audi at Le Mans. As for the prospect of Mercedes competing in other international racing series, Zetsche added that year-long preparations for 24 hours of racing at Le Mans didn't present a good cost-benefit ratio in his estimation, but that Formula E (where Audi currently supports a quasi-works entry) would be worth a closer look.
