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

BMW 5 Series Gran Turismo won't be a one-and-done model

The BMW 5 Series Gran Turismo seems like a model without a real segment to fit into. It doesn't quite match the mold for the swoopy four-door coupe niche like the Porsche Panamera or the brand's own 6 Series Gran Coupe. However, the vehicle isn't really a station wagon to appeal to those utilitarian buyers, either. Despite this identity crisis, BMW is reportedly prepping another GT for the next-gen 5 Series platform. According to German magazine Auto Motor und Sport, the 5 Series GT somehow has been a big enough sales success in the US and China to warrant another model. The next one would allegedly arrive in 2016, which is the about the same size as the future 5 Series sedan. The magazine speculates the new GT could lose about 221 pounds in the transition and be offered with four- and six-cylinder powertrains, plus a plug-in hybrid with an electric driving range estimated at around 19 miles. Globally, China is actually the larger 5er GT market than the US. According to IHS senior analyst Stephanie Brinley to Autoblog, the variant sold 21,089 units worldwide in 2013 (2014 is still being tabulated), and that represented about 5.7 percent of the 370,930 total sales for the 5 Series. China bought 42 percent of the world's GTs, compared to about 10 percent of the mix from the US. Europe, meanwhile, took about 29 percent of them that year. While the GT's sales figures make up just a fraction of the overall 5 Series, the variant is still a moneymaker for BMW, and IHS forecasts a second generation, too. "The 5 Series range as a whole is stronger for having this product, and it's very likely that the company's profit margin is higher on the GT, even with the cost of some dedicated sheetmetal and tooling," said Brinley.

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.
