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

Mini might build a sedan because it's running out of shapes

Rumors suggest we could soon see a Mini with a trunk to haul your junk. Autocar cites unnamed insiders who claim the sedan is part of the brand's plan for upmarket growth. There's even a possibility the new model could use the Riley moniker in reference to the Elf (pictured above) from the 1960s, which was a Mini with a tiny trunk. The Mini sedan would use BMW's front-wheel-drive platform that underpins the X1 and Clubman and might share the wheelbase and frontend styling with the Clubman as well, according to Autocar. Mini's execs think the four-door would perform especially well in North America and China, where there's less demand for hatchbacks. Ralph Mahler, vice president of Mini's product management, hinted at the possibility of the four-door to Autocar. "For example, in Asia and the US, the sedan segment is very big. This is very interesting to us, of course," he said. Mahler admits that many people don't know about the Mini-based vehicles with trunks from the '60s, like the Riley Elf, so it would be hard to market the new model on that heritage. This could be the perfect time to add a Mini sedan to the lineup, and it might not be a completely new idea for the brand under its BMW stewardship; a rumor from 2012 shows that Mini's bosses considered a four-door at least once before. The company launched new versions of its Hardtop, Convertible, and Clubman, and even added four-door and all-wheel-drive versions of the Hardtop to further blur the lines between that car, the Clubman, and the Countryman. The next-generation Countryman crossover should debut later this year, and the brand reportedly cancelled the Superleggera Vision roadster and Rocketman compact, as Mini has chosen to go big with its new models and its lineup breadth. There are only so many versions of a hatchback a company can make, and the short-lived Mini Coupe wasn't exactly a huge success. If Mini is going to try a new body style, a sedan actually makes some sense, even if we'll probably prefer the look and practicality of the hatches. Related Video:

X1, 3 Series power BMW back into global luxury autos sales lead

BMW managed to eke ahead of Audi for the global luxury sales crown in February. According to Bloomberg, BMW saw deliveries swell by 7 percent in February, besting the 3.2 percent jump enjoyed by Audi and giving BMW a 407-unit delivery lead over its rival last month. Mercedes-Benz, meanwhile, continued to falter, with the brand selling some 37,229 fewer machines than BMW, whose factories are running at full capacity to keep up with demand. Models like the X1 (shown above) enjoyed a sales increase of 40 percent in February while the company's bread-and-butter 3 Series jumped by 26 percent.
Mercedes-Benz hopes to stem its continued market share loss with the addition of the entry-level CLA sedan to its portfolio in April. The company is set to roll out an updated version of its cash-cow E-Class at the same time, and a new-generation S-Class will follow along shortly thereafter. Meanwhile, the company is increasing production to meet demand for its A and B-Class models.
