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.

2014 BMW 4 Series

Because Four Is Greater Than Three
Say what you will about the name 4 Series, there is a method to BMW's madness. On one hand, it's easy enough to just buy into the logic that odd numbers are reserved for sedans and wagons, and that even numbers are reserved for coupes and convertibles. On the other hand, consider the idea that the higher numbers are used to separate the more dynamic, more engaging vehicles that use the same platform. It's that sort of separation that differentiates the 6 Series so nicely from its 5 Series roots, after all. And if we're being cynical, it also allows BMW to charge a bit more money for its lower-volume offerings.
So with the new two-door version of the 3 Series, BMW has gone the route of strengthening the dynamic virtues of its F30 chassis to create a car that's more removed from its sedan kin than one might think. And after spending some time with the new 4 Series on the roads around Lisbon, Portugal, as well as the famous Circuito do Estoril racetrack, it's increasingly clear that calling this car a 3 Series Coupe simply wouldn't be fair.

BMW readying impressive track-focused M Power App

There are a lot of questionable automotive apps that people put on their smartphones these days, but BMW has created what could be one of the most useful and integrated car apps ever. The new M Power App, which will be available this summer only for Apple iPhones, allows BMW owners a whole new way to record their performance on the street or on a track. During the launch of the recent BMW M6 Gran Coupe, BimmerPost was able to get a full demonstration of how this new app works.
Far more involved than the current M Power Meter, the M Power App records data from in-car sensors and acts as a telemetry tool to allow drivers to see how they did on a particular track. Aside from an overlay on a track map showing acceleration and braking applications as well as head-to-head comparisons, the app also shows a line graph of everything from brake and throttle inputs to g-force, fuel mileage and engine speed. A small visual on the screen also shows steering angle, and lap times and speeds can all be stored as well. The data can even be shared with others, whether for bragging rights or instruction purposes.
This app works on any newer BMW equipped with the BMW Apps option, but the phone must be tethered to the car and the data understandably cannot be viewed while driving. Scroll down for the video demonstration recorded recently at Austin's Circuit of the Americas.
