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 John Cooper Works wears a racing suit for the Nurburgring

Mini is returning to the Nurburgring 24 Hours, one of the most grueling races in the world, after a decade-long hiatus. The BMW-owned British firm is supporting a private team called Bulldog Racing that's entering a heavily-modified John Cooper Works Hardtop into the event. The track-bound hatchback doesn't look, sound, or feel like a standard John Cooper Works Hardtop. Several modifications were made to prepare it for the race, including fitting the turbocharged, 2.0-liter four-cylinder engine normally found in the Clubman and the Countryman. It develops 306 horsepower and 330 pound-feet of torque, and it spins the front wheels via an eight-speed automatic transmission with an integrated differential lock. For context, the standard John Cooper Works Hardtop is rated at 228 horsepower and 236 pound-feet of torque. The engine slurps fuel from a bigger, 26-gallon tank and it exhales through a modified exhaust system. Dialing in more power wouldn't be much use without suspension and braking modifications to keep it in check. To that end, the Hardtop gains an adjustable suspension system, reinforced Uniball bearings for all moving chassis and suspension parts, and more powerful brakes from BMW M Performance. Bulldog Racing also installed a full body kit that looks like the one worn by the John Cooper Works GP, which is limited to 3,000 units. It includes a front splitter, flares over the wheel arches, an adjustable rear wing, and a rear diffuser. There's more than initially meets the eye: we're told that the underbody is completely covered as well. Makrolon windows replace the production car's glass units to reduce weight. Inside, you won't find many components that still carry a Mini parts number. Open the driver's door, which now features a carbon fiber panel, and hop over the full roll cage to settle into an OPM racing seat that faces a KMP quick-release steering wheel. The digital instrument cluster and, somewhat surprisingly, the infotainment system's screen remain, but the rear seats and most of the trim pieces have been removed. Bulldog Racing will continue to fine-tune the track-bound Hardtop in the coming weeks. Some tests will be performed on the Nurburgring, while others will take place on the private test track that BMW operates near Miramas, a town in the south of France. The hot hatch is scheduled to make its competition debut at the 50th edition of the Nurburgring 24 Hours taking place in Germany from May 26 to 29.

Mini prepping new John Cooper Works convertible

Those enamored by a Mini's spritely handling and retro styling but looking for that extra performance edge have had a succession of John Cooper Works models to choose from, straight through to the latest version unveiled this week in Detroit. And now, Mini appears to be preparing a JCW version of the new convertible. Spied undergoing cold-weather testing in Scandinavia, this Mini prototype appears to be wearing the tell-tale signs of a JCW model, combined with the folding fabric roof of the convertible model. Mini has yet to reveal the convertible version of the latest, third-generation Cooper, but while we're expecting it to take a similar approach to the outgoing model – with four seats and a soft top stacking up in the back when open – there's always the chance that, with the demise of the two-seat Roadster model, the roof on the new cabrio will fold more flush with the rear deck. Since this prototype, like the previous one we saw over a year ago on a flat-bed truck, has its roof up, it's impossible to say at this point. What we can see is that this prototype, though decked out in swirly camouflage, is wearing the upgraded body kit of the new JCW hatch, including the flared wheel arches, big air vents and dual central exhaust tips. The wheels, though wearing snow tires appropriate to the climate, fill those flared fenders well, and are in turn packed with what look like pretty big brakes. Expect the 2.0-liter turbo four to pack the same 228 horsepower and 236 pound-feet of torque as the hardtop version, only with the added thrill of wind in your hair. Of course, if Mini is indeed preparing to launch a JCW version of the new convertible, there's nothing to say it won't do the same with the four-door Hardtop, the upcoming Clubman wagon or any other body-style in the new range.
