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 stretches out with new Hardtop 4 door [w/video] [UPDATE]

UPDATE: Information on US availability, specification and nomenclature added to the updated text below.
Few automakers have managed to spin off as many variants of essentially one vehicle as Mini has. The second generation produced even more versions than the first, and now that the third generation is upon us, the process is starting all over again. The jury may still be out on whether parent company BMW will roll out as many body-styles of this latest Mini as it did with the last, but here's our first indication.
Following the introduction of the new three-door Mini hatchback at the LA Auto Show, the Anglo-Saxon marque has introduced a new five-door model. Or four-door, depending on which Mini office you're speaking to: while this new model - an addition to the lineup and not a direct replacement for anything previously offered - is called the Mini 5 door by the factory, here in the US it's called the Mini Hardtop 4 door. Whatever you call it, though, this new Mini is essentially the same as the three-door model (or two-door model with a tailgate), only with - you guessed it - two extra doors. The new Clubman will be a separate model altogether.

Xcar takes the Mini Challenge, and it sounds awesome

The third-generation Mini is well and truly on sale in markets across the world. The new four-door model should be arriving soon, if it isn't already on sale in your neck of the woods, and the latest John Cooper Works model made its official debut just a few weeks ago at the 2015 Detroit Auto Show. We aren't going to be talking about any of those right now, though. That's because our chums at Xcar took it upon themselves to sample the third-generation Mini Challenge racecar, a 275-horsepower, hardcore, fully committed competition version of the otherwise adorable Mini Cooper S. At roughly 30,000 British pounds (about $45,200 at today's rates) there's a lot to like about the Challenge car. Aside from a gutted cabin and aggressive aerodynamic kit, the racer has been fitted with slick tires, a Quaife sequential gearbox, adjustable dampers, Alcon brakes and a consequently lower curb weight – under 2,600 pounds with an average-sized driver. It's fair to say the Challenge driving experience figures to be unlike your typical road-going Mini. And considering that, we think the folks that built the car, Total Track, have fulfilled their promise of delivering a "touring car experience at a fraction of the cost." Have a look at the Xcar video and let us know what you think. Be sure to crank up your speakers, because the Challenge sounds excellent.
