The next-generation wearable will be your car

This year's CES has had a heavy emphasis on the class of device known as the "wearable" – think about the Apple Watch, or Fitbit, if that's helpful. These devices usually piggyback off of a smartphone's hardware or some other data connection and utilize various onboard sensors and feedback devices to interact with the wearer. In the case of the Fitbit, it's health tracking through sensors that monitor your pulse and movement; for the Apple Watch and similar devices, it's all that and some more. Manufacturers seem to be developing a consensus that vehicles should be taking on some of a wearable's functionality. As evidenced by Volvo's newly announced tie-up with the Microsoft Band 2 fitness tracking wearable, car manufacturers are starting to explore how wearable devices will help drivers. The On Call app brings voice commands, spoken into the Band 2, into the mix. It'll allow you to pass an address from your smartphone's agenda right to your Volvo's nav system, or to preheat your car. Eventually, Volvo would like your car to learn things about your routines, and communicate back to you – or even, improvise to help you wake up earlier to avoid that traffic that might make you late. Do you need to buy a device, like the $249 Band 2, and always wear it to have these sorts of interactions with your car? Despite the emphasis on wearables, CES 2016 has also given us a glimmer of a vehicle future that cuts out the wearable middleman entirely. Take Audi's new Fit Driver project. The goal is to reduce driver stress levels, prevent driver fatigue, and provide a relaxing interior environment by adjusting cabin elements like seat massage, climate control, and even the interior lighting. While it focuses on a wearable device to monitor heart rate and skin temperature, the Audi itself will use on-board sensors to examine driving style and breathing rate as well as external conditions – the weather, traffic, that sort of thing. Could the seats measure skin temperature? Could the seatbelt measure heart rate? Seems like Audi might not need the wearable at all – the car's already doing most of the work. Whether there's a device on a driver's wrist or not, manufacturers seem to be developing a consensus that vehicles should be taking on some of a wearable's functionality.

BMW i introduces home energy storage using i3 batteries

What happens when you take the battery out of a BMW i3 and put it into a grid-connected box? According to BMW, you get a home energy system that, "integrates seamlessly with charging stations and solar panels." It should also give i3 owners a bit more value out of their used cars, if BMW ever explains how they can sell their cars or the batteries back to the company for use in a system like this. Announced at the EVS29 event in Montreal today, BMW's stationary energy storage system solution uses i3 batteries to store excess electricity when available for use in power outages or when demand is high. While the system uses new 22- or 33-kWh i3 packs now, it "can be expanded to incorporate 2nd Life Batteries as they become available in the market." BMW says that the average US household used 15-30 kWh of electricity a day in 2014, so the BMW's packs would hold enough juice for a day or two, depending on the situation. Currently, BMW is testing out repurposing used Mini E batteries in a solar electric grid system at the BMW Group Technology Office in Mountain View, California.

The BMW i3 battery system – from the power source of the Ultimate Driving Machine – is integrated into an intelligent storage solution for residential and commercial applications. Montreal, Quebec June 21, 2016. ... BMW i, a leader in innovative electromobility since 2011, announced a stationary energy storage system solution integrating its BMW i3 vehicle battery at the Electric Vehicle Symposium & Exhibition 29, making it the first automotive manufacturer to utilize a complete automotive high-voltage battery for energy storage. The battery storage system electrified by BMW i, enables customers to more fully realize their commitment to sustainability – and to take the next step towards energy independence. With this system, which integrates seamlessly with charging stations and solar panels, customers can offset peak energy costs and also enjoy the added security of an available backup energy supply during power outages. The system utilizes BMW i3 high-voltage batteries and can be expanded to incorporate 2nd Life Batteries as they become available in the market. This strategy will extend the useful life of the battery for the owner, even beyond in-vehicle use.

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.
