Mini Cooper SE Convertible wheels made entirely from recycled aluminum

Mini has revealed an interesting fact about its limited-run Mini Cooper SE Convertible: It's the first production car with wheels made from 100% recycled aluminum. Despite sharing the same look as wheels available on the regular SE hatch, they're actually much more environmentally friendly. The wheels were developed with Swiss wheel manufacturer Ronal. The company sells aftermarket wheels under the Ronal and Speedline brands, and it supplies OEMs. And it's no stranger to more environmentally-friendly wheel production. It supplies wheels for the Audi E-Tron GT that are made using a smelting process that produces oxygen rather than carbon dioxide, and it now has a line of claimed carbon-neutral aftermarket wheels. But back to the Mini's wheels. Using all recycled aluminum has the obvious benefit of not requiring new aluminum to be manufactured. But the benefits are greater than just the raw material use. Mini points out that a major improvement in carbon emissions comes from being able to skip the electrolysis process for new aluminum manufacturing. Pure aluminum is extracted from aluminum oxide (which is in turn taken from the mineral bauxite). To do this large amounts of electricity are passed through molten solutions of aluminum oxide and cryolite (which takes energy to heat) across graphite cathodes and annodes. Not only does this use a lot of electricity that has its own carbon costs, the oxygen that separates from the aluminum bonds to the graphite annodes, yielding more carbon dioxide (which is why the production of those Audi wheels is also interesting). In total, Mini says the recycled wheel production reduces carbon emissions by 75%. More specifically, it estimates about 0.16 kilograms (0.35 pounds) per kilogram (2.2 pounds) of aluminum used. Mini also stresses that this process still maintains all the strength of conventional wheels, just in a greener way. And of course, the wheels themselves are recyclable again. Mini, and BMW more broadly, are looking at ways to upscale the process and to source suitable recyclable products, likely other old wheels from cars no longer on the road. Though neither company said anything about when we'll see fully recycled wheels more widely available. Related Video: MINI Electric Pacesetter inside and out

BMW M235i Racing takes to the track

Last month, BMW showed off a motorsports version of its new 2 Series Coupe called the M235i Racing. While that single image was obviously a rendering or design model, BMW Motorsports has now released a video showing the real deal being tested.
From what we can tell from beneath the camouflage, the wide-body fenders ­- to accommodate a 3.5-inch track stretch - are slightly different than the image BMW previously released. Still, the body is noticeably different from the stock coupe. The video, which is posted below, shows glimpses of the race-prepped interior, including a full FIA roll cage, but more importantly we get to hear the 333-horsepower engine and its throaty exhaust in action.

BMW moves car-sharing program from San Francisco to Seattle

BMW is shifting more focus towards mobility services, which include car sharing and ride sharing. A new service, called ReachNow, will start out from Seattle and expand to other cities later. At first, the main competitors are ZipCar and Car2go, but ReachNow will also have to battle Uber. In a number of European cities, BMW already operates under the DriveNow program, which is getting revamped to better suit the US marketplace. Up until December, BMW made DriveNow available to San Francisco customers, but was forced to pull out due to parking space issues that are characteristic to SF. Perhaps Seattle makes things easier for BMW, though parking in any major metro area is sure to present some level of difficulty. BMW's idea is to offer pay-per-use pricing for driving a BMW 3-Series, BMW i3 electric vehicle or a Mini, which can be picked up from a street corner either by a 30-minute reservation or on-the-go, depending of the user's needs. Flexibility is key, whether you need a car for just a short while or for a longer weekend trip. The Seattle fleet will consist of 370 vehicles distributed across town. Later on, the service will expand to offer taxi-like ride sharing, to compete with Uber. As the glimmer of car ownership has faded in big cities, BMW wants to make sure it can still put people behind steering wheels or in the back seats. Luxury vehicle ride sharing is also on the cards, seemingly as a way to balance out the decidedly utilitarian choice of cars currently available.
