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

BWM 135i with M3 V8 engine swap combines two things we miss the most

If you've ever listened to the Autoblog Podcast, you've doubtlessly heard my views on the BMW 1 Series M Coupe. I don't much care for it. That's not to say it's bad, so much as it just isn't what an M car should be. Steven Ewing, Seyth Miersma and a number of other Autoblog staffers think I'm crazy (It's true, he is crazy –Ed.), but whatever. My position on the 1M would be dramatically different, however, had it been fitted from the factory with the truly fantastic 4.0-liter V8 from the E92 M3 (the last great M car, in this writer's humble opinion). Matt Farah of Drive took to the wheel of a 135i that's been completely reworked by Performance Technic and is owned by Marco Svizzero. The car required a salvageable E92 and what we imagine is an incalculable amount of wrench time, with the result being, as Farah says, "possibly the best BMW you could build at any price." Oh, and it sounds absolutely delicious. Check out the car in action.

2015 BMW M4 gets initiated into the club

It's easy for enthusiasts and traditionalists to give BMW a hard time these days, what with its plans to add more front-wheel drive models and seeming move away from more emotionally connected cars. However, the push for perfection that underscored its old Ultimate Driving Machine motto is still in there, especially in its M models. In fact, the first M4 recently made it to US shores, and the company thought the only appropriate way to celebrate was to introduce its new coupe to some of its high-performance forefathers.
The M4's initiation into the M car brotherhood involved bringing together no fewer than 52 classic and newer models - including four racecars and many privately owned vehicles - to an empty parking lot and letting the coupe drift and slalom around them to say hello. According to BMW, there was a combined 11,566 horsepower on hand. It takes a pretty trusting owner to stand back and watch as a brand-new vehicle slides its tail out with the rear wheels smoking within feet of their pride and joy. Stay tuned until the end where the owners and their cars get a shout out in the credits. Scroll down to read BMW's press release about it.
