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 celebrates 30 years of M5 with 600-hp super sedan

It's been 30 years since BMW rolled out the first M5, and while displacement and cylinder count may have fluctuated over those past three decades, output has only increased. The first-generation E28 M5 packed a 3.5-liter inline-six with 252 horsepower and 243 lb-ft of torque. The second-gen E34 model that followed added an extra 100 cc (and later 200 more) to produce 310 hp and 266 lb-ft. The E39 followed with a 4.9-liter V8 churning out 394 hp and 369 lb-ft, replaced by the award-winning 5.0-liter V10 in the E60 with its 500 hp and 380 lb-ft before BMW rolled out the latest model with a 4.4-liter V8, its twin turbos making up for the two dropped cylinders and 600 cc of displacement to produce 560 hp and 502 lb-ft of torque. But even that's being left in the dust by the new special edition you see here.
The 30th Anniversary Edition BMW M5 packs that same 4.4-liter twin-turbo V8, but cranks the output up to a nice, round 600 horsepower and a solid 516 lb-ft of torque to go with it. That makes it more powerful, not only than any M5 that's come before it, but also any of its rivals. The Jaguar XFR-S and Audi RS6 Avant (the latter only available as a wagon and not in North America) both lag behind this ultimate of Ultimate Driving Machines; only the Mercedes-Benz E63 AMG trumps it on torque (but not on power), with 531 lb-ft in stock form and 590 in the S-Model.
As a result, the 0-60 time drops from a quoted 4.2 seconds in the stock M5 to a scant 3.7 in the 30th Anniversary edition (just one tick behind that twistier E63 S). The special M5 also comes with the Competition Package as standard, as well as a dedicated control module for the Active M Differential, a special Frozen Dark Silver matte finish, 20-inch alloys and black chrome badges. Special badges abound inside as well, where you'll also find black leather and Alcantara upholstery and aluminum trim. There'll even be a dedicated one-day course offered to owners at The Thermal Club in Palm Springs, CA, to further sweeten the deal.

Audi overtakes BMW as adulterers' favorite car brand

As Audi hopes to surpass BMW as the top-selling luxury automaker, sometimes it has to look at the small victories, too. For instance, IllicitEncounters.com - a UK dating site for married folks (also known as adultery) - is reporting that a recent poll shows that more people willing to cheat on their spouses drive an Audi. Last year, this same poll showed that BMW was the car-of-choice for adulterers.
With Audi on top (pun intended) and BMW bumped to number two, Mercedes-Benz, Volvo and Volkswagen round out the top five car brands owned by unfaithful wives and husbands. Check out the poll over at IllicitEncounters.com, but be sure to clear your browser history afterward. You know, just to make sure your spouse doesn't get the wrong idea about the websites you visit.
