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 reveals new X5 Security Plus in Moscow

A major player in the Russian market, BMW is heading to the Moscow Motor Show this month with a slew of local debuts... most of which we've already seen. But among all the new models making the trek from Bavaria to Moscow will be the new X5 Security Plus.
In a new-model launch that will surprise exactly no one, BMW's latest armored vehicle upgrades the X5 with enhanced protection for oligarchs against Chechen rebels, AK47-touting gangsters and missiles randomly falling on Crimean highways. Now meeting the VR6 standard of ballistic protection, the new X5 Security Plus incorporates reinforced bodywork, seats and joints, along with bulletproof glass.
Of course all that reinforcement (not to mention the jars of beluga caviar and bottles of Stoli in the glovebox) will come with a weight penalty, but the 4.4-liter twin-turbo V8 ought to do the trick, driving 450 horsepower through BMW's xDrive all-wheel-drive system to get the vehicle's occupants out of a war zone in a hurry.

Ward's Automotive Ten Best Engines of 2014 dominated by diesels, turbos

With the Car and Driver Ten Best decided, the North American Car and Truck of the Year finalists announced and Cadillac, Ram and Subaru chalking up wins with Motor Trend, it's fair to say that the automotive awards season is in full swing. The next set of trophies to be handed out will be from Ward's Automotive, which has announced the winners of its 2014 10 Best Engines.
The latest contest was marked by the widespread emergence of diesel power and the continued success of turbocharged engines. There was even an electric motor on this year's list. In fact, only three of the ten winners were naturally aspirated and only two winners returned from last year.
"We weren't looking to throw the bums out, as they might say about an election. We were just really impressed with the flood of new powertrains," said Ward's Automotive Editor-in-Chief Drew Winter. Those new powertrains include the 83-kilowatt electric motor from the Fiat 500e, the 1.0-liter, EcoBoost three-cylinder from the Ford Fiesta and the 2.0-liter turbodiesel from the Chevrolet Cruze.
