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.

Watch man destroy his M6 'lemon' with a sledgehammer and ax

Just to be clear, the owner of this BMW M6 isn't ready for another one. He and his friend destroyed the V10-powered coupe in anger at the entrance to the Frankfurt Motor Show in a decidedly public fashion. Bild and GT Spirit report that the owner was angry over mysterious quality and reliability issues that he claims BMW wasn't able to fix. What we have here, folks, is claimed to be a very expensive lemon.
As the story goes, owner Pourmohseni Hadi bought the 2007 M6 in 2008, and five years later, he is still complaining about mysterious vibrations, rattles and severe jolts during gear changes - the latter he says have caused passengers to become nauseous. The car was taken to several BMW repair shops in Italy and Hadi says he he has written a letter to the automaker about his issues, but the car was never fixed and the letter unanswered, he claims. What we don't know is how many miles the car has been driven and when all these problems started happening. The situation reminds us of a certain Lamborghini Gallardo from a couple years back.
While we understand Hadi's frustration, perhaps an M6 just doesn't suit his tastes. After all, we'd be lying if we said a perfectly functioning M6 of this generation wasn't bumpy over uneven surfaces and wouldn't make some passengers nauseous, with its stiffly sprung suspension and dizzying 500-horsepower V10. Anyone wanna bet his M6 was equipped with one of BMW's notoriously abrupt SMG single-clutch gearboxes?

2015 BMW S 1000 RR looks to retain sportbike supremacy

The BMW S 1000 RR is already a pretty potent member of the superbike ranks, but BMW is revealing a host of upgrades for this two-wheeled lightning bolt at the Intermot 2014 motorcycle show that should make it even faster.
The biggest additions to the latest 1000 RR are its new cylinder head, lighter valves and different intake cam to tweak even more power from the bike's 1.0-liter, four-cylinder engine, and BMW now rates it at a claimed 196 horsepower (or 199 horses if you go with the European measurement, converted from 146 kilowatts), a boost over the first-gen's 193 ponies, and 83 pound-feet of torque through a six-speed gearbox. Those adjustments would probably be enough to make the cycle a tick faster alone, but the Bavarian engineers also cut 8.82 pounds (4 kg) to bring the motorcycle's weight with a full tank of fuel to a feather-light 450 pounds. Much of that diet comes from the redesigned exhaust that cuts about 6.6 pounds off the scales.
Cradling that tweaked engine is a redesigned, lighter frame with fully adjustable springs. The bike also comes standard with Race ABS, stability control, seven-step variable traction control and three riding modes. In terms of styling, all of these changes are communicated through an updated fairing with repositioned, though still asymmetric, headlights.
