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.

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.

BMW's DTM champ swaps rides with Mini's Dakar winner

BMW may not race in F1 any longer, and it doesn't compete with Audi and Porsche in the LMP1 class at Le Mans. It even shut down Mini's short-lived effort on the World Rally Championship. But that doesn't mean it doesn't race at all. In fact it's the current reigning champion both in DTM and at Dakar. So to highlight its varied motorsport programs, the German automaker had two of its top drivers swap rides. German driver Martin Tomczyk, who won the DTM title in 2011 and now drives for BMW, took to Nasser Al-Attiyah's Mini All4Racing Countryman on the sand dunes of Dubai. Meanwhile the Qatari driver, who has won the Dakar Rally two times now, took to the wheel of Tomczyk's BMW M4 DTM around Oschersleben in Germany. They even repeated the game of musical chairs at Hockenheim over the weekend. If anything, the promo clip shot by Red Bull just goes to show how different the varied racing machinery can be, and the challenges posed to racing drivers switching between disciplines. But lessons aside, it's a cool clip, so check it out above. Two champions swap cockpits: Martin Tomczyk drives the MINI ALL4 Racing, Nasser Al-Attiyah the BMW M4 DTM. Munich (DE), 1st May 2015. From asphalt to sand and back again: BMW DTM driver Martin Tomczyk (DE) and MINI ALL4 Racing ace Nasser Al-Attiyah (QA) both entered unfamiliar territory and took each other's cars for a test drive. As part of a video shoot for BMW Motorsport Premium Partner Red Bull in Dubai (AE), Tomczyk, a proven master of his trade on asphalt as the 2011 DTM Champion, took the wheel of the MINI ALL4 Racing, with which X-raid has won the famous Rally Dakar the last four years. During DTM testing in Oschersleben (DE), Al-Attiyah was given the opportunity to drive Tomczyk's BMW M Performance Parts M4 DTM. Two wins at the Rally Dakar are just some of the successes the rally driver from Qatar has had to date. He followed up his first victory in 2011 by winning in the MINI ALL4 Racing in January 2015. "Driving the MINI ALL4 Racing through the sand and over the dunes in Dubai was a fascinating experience and was so much fun," said Tomczyk. "The car has an incredible amount of torwue – and the test in the dunes was an amazing adrenalin rush even for an experienced race driver such as myself. It's totally different to driving on a circuit.
