BMW i3, i8 sales strong enough to reach almost 17,800 in 2014

BMW makes its futuristic i brand vehicles – the i3 and i8 – at a plant in Leipzig, Germany. But the customers most willing to buy one of these plug-in cars live in the country where the lightweight carbon fiber used in the body structure is made: the United States. Speaking at the Detroit Auto Show this week, Ian Robertson, member of the Board of Management at BMW AG, said, "The US is already our largest market for our electric vehicles, the BMW i3 and BMW i8. Worldwide, we sold close to 18,000 BMW i models last year. Nearly three-quarters of these sales occurred in the second half of the year, when the global rollout – including the US – really got underway. Demand for these vehicles continues to be high and I'm delighted that we've been able to increase production to meet that demand." That sounds great, but the numbers aren't huge. BMW sold 6,092 i3s and 555 i8s (for a total of 6,647 i vehicles) in the US last year. Globally, BMW sold over two million vehicles in 2014, and 17,793 of those were plug-in i vehicles (16,052 of the i3 and 1,741 i8s). The production increase wasn't huge. BMW was making just 10 i8 vehicles a day at the beginning, but doubled that to 20 last fall. Since last spring (around April or May), the company has been making over 100 i3s a day, BMW spokesperson Verena Von L'estocq tells AutoblogGreen. Getting production right this first year has meant slow going, but "We're comfortable now," she said, adding that BMW expects more production increases in the future. Related Video:

LA Design Challenge invokes biology for 2025 concepts [w/poll]

Participants in the annual LA Design Challenge always manage to come up with edgy, wacky designs for future vehicles, but with a theme of "Biomimicry and Mobility: 2025" this year's crop of cars might be the quirkiest we've ever seen. As usual, automotive designers from around the world participated in this year's competition, and all the designs will all be unveiled next week during the LA Auto Show with a winner being announced on November 21.
Chinese automakers made a strong showing with Qoros, SAIC Motor, JAC Motors (the company responsible for the Ford F-150 clone) and Changfeng all bringing interesting takes on the biology, human intelligence and sustainability theme. One of the more innovative ideas among these automakers is the Qoros Silk Road System allows autonomous vehicles to drive in packs similar to how ants travel. Speaking of ants, the SAIC Motor Mobiliant (shown above) gets its design from the shape of an ant's body, and, like the insect, it can climb building acting as a personal elevator as well. The JAC Motors design also merges vehicle and building design, while the Changfeng LaBrea inspired by the design of muscle fibers.
Other entrants include Subaru and US-based design teams for BMW, Toyota and Mazda. BMW's duo of concepts mimic plant and animal life. The LA Subways concept acts as a submersible, single-person vehicle to take advantage of the LA river, with a shape similar to an Ocean Sunfish. The Sustainable Efficient Exploratory Device (SEED) imitates the shape of a seed pod, and uses propulsion methods inspired by a shark, dragonfly and a water bug. Mazda's Auto Adapt might be the most car-like concept of the bunch, while the Subaru Suba-Roo and the Calty-designed, Toyota e-grus are the most mind-blowingly awesome.

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
