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

2015 BMW M4 Coupe ditches some doors, gains some grunt

If you saw our earlier post about the hot new BMW M3 Sedan and were about to call blasphemy for no coupe version, just settle down, silly. Remember: BMW now badges its two-door 3 Series models with the number four, and thus, meet the 2015 M4 Coupe. Looks hot, right?
So yeah, it's pretty much just the M3 with two less doors, but that doesn't make it any less important - or potent. Power comes from a turbocharged, 3.0-liter inline six-cylinder engine, sending 425 horsepower and 406 pound-feet of torque to the rear wheels via either a six-speed manual or seven-speed dual-clutch transmission. You know, the usual.
Not only is the M4 more powerful than the M3 Coupe it replaces, it's a good deal lighter, too. BMW has managed to cut 176 pounds of weight out of the M4, and that means, with the increased output numbers, that the M4 will scoot to 60 miles per hour in 3.9 seconds with the DCT or 4.1 seconds with the do-it-yourself tranny. Either way, that's not what we'd call slow.

BMW i8 named Autoblog's 2014 Technology of the Year [w/video]

The winner of Autoblog's 2014 Technology of the Year award was given this year for not just one technology, but for how a suite of technologies worked together to make one impressive vehicle. The BMW i8 was named the winner Wednesday night at the Belasco Theater in downtown Los Angeles, just outside the Los Angeles Auto Show. Autoblog's editorial staff agreed that the i8, which drew crowds of attention during our testing days, represents a future of driving that we can't wait to see happen. "I do believe that green vehicles solve a very fundamental problem, and if a car like the i8 can get a rich man with good knees (to get in and out of the car) to drive something with a plug instead of a 12-mpg sports car, then mission accomplished," says Sebastian Blanco, editor of AutoblogGreen and one of our judges. The panel reviewed nearly 50 qualified submissions from readers, editorial staff and industry, the panel of judges named the following as finalists: Dodge's SRT Performance Pages (read more here) The Subaru Eyesight forward collision warning system (read more here) The Performance Data Recorder in the 2015 Chevy Corvette (read more here) The 1.0-liter Ecoboost engine from Ford (read more here) Chrysler's 3.0-liter EcoDiesel V6 engine (read more here) Ultimately, we picked the car that excited us the most. The BMW i8 has a throaty exhaust note when accelerating. It's got carbon fiber, and a plug-in hybrid system that uses a small 1.5-liter three-cylinder engine and an electric motor. It has through-the-road all-wheel drive, and in Europe it'll come with laser beams for headlights. All that, and it's a massive eye catcher. People stop and stare when they see this car, for good reason. It's simply gorgeous. For a more in-depth look at our testing of the car, click here.
