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 225xe and 330e get official ahead of Frankfurt

BMW is going green at the 2015 Frankfurt Motor Show with the launch of the 225xe and 330e plug-in hybrids, but the Bavarians are spilling the beans about them early. The models are the latest to use Bimmer's eDrive tech that's derived from the i3 and i8. The modular system allows the automaker to roll out PHEVs through its range. For the new 225xe, eDrive makes for an all-wheel drive, PHEV version of the brand's usually front-wheel drive wagon. Other than the door hiding the charging point, the vehicle looks the same as other versions. Underneath the skin, it uses a 134-horsepower, 1.5-liter turbocharged three-cylinder to spin the front-wheels through a six-speed automatic. An 87-hp electric motor with a 7.7-kWh lithium-ion battery turns the rear, and the result is a total system output of 221 hp and 284 pound-feet. BMW claims a sprint to 60 miles per hour in 6.7 seconds, but this 2 Series shines in fuel economy with between 112 and 118 miles per gallon on the European cycle. Multiple driving modes let the driver find the right mix of power and mileage, but the electric range is only 25 miles. Like the standard version, there's no chance of the 225xe coming here, but prices in Germany start at 37,800 euros ($42,050, at current rates) later this year. For buyers wanting BMW's iconic 3 Series as a PHEV, there's the 330e. Again, the only major styling difference is the charging door on the front fender. Its 87-hp electric motor and 181-hp, 2.0-liter turbocharged four-cylinder both send power to the rear wheels. The result is a total system output of 248 hp and 310 lb-ft. The 330e maintains a 50-50 weight distribution, and fuel economy on the European cycle is rated between 112 and 124 mpg. Even with that efficiency, the 330e can get to 60 in 6.1 seconds. The 7.6-kWh lithium-ion battery allows for 25 miles of EV range, too. BMW's gargantuan press release goes into exhaustive detail about every technological element in the two new models. You can check out all of those details below ahead of the Frankfurt reveal, below. BMW eDrive – the latest generation. 1. BMW eDrive technology. Setting a new benchmark for efficiency. The innovative BMW eDrive technology in the new BMW 225xe and new BMW 330e once again underlines BMW's leading role in the premium segment when it comes to powertrain electrification. BMW eDrive technology includes a number of cutting-edge plug-in hybrid components and makes a significant contribution to reducing fuel consumption and emissions.

Upcoming new Alpina B7 teased

BMW does not make an M7. It never has, despite rumors, trademark filings, and the actual desires of the people that would build such a car. That means that while we're stuck waiting for BMW to see how foolish not building an M is, the most potent 7 Series you can get wears an Alpina badge on the nose. Meet the newest version of that car... sort of. BMW and Alpina haven't taken the wraps off the next B7 just yet, opting instead for an opera-accompanied teaser of the new car undergoing track testing. The car is lightly camouflaged – there's enough to make it clear it's a 7 Series, but not so undisguised as to reveal too much of the Alpina bodywork. There's a more aggressive bumper, a meaty rear spoiler, and sharper side sills, along with what are probably Alpina-specific wheels, but more precise details are hard to discern. What isn't difficult to pick out, though, is ear-tingling exhaust note. The last two Alpina B7s have built on the standard 7 Series' engine, and this new model likely won't be any different. That should mean a breathed upon 4.4-liter, twin-turbocharged V8 which goes well above the unfettled car's 445 horsepower and 480 pound-feet of torque. The extra power, along with the donor car's new lightweight carbon-fiber passenger cell, should make for tantalizing performance capabilities. The current 750i xDrive takes 4.3 seconds to make the sprint, and the B7 model that this new machine will replace hits 62 in 4.6. We'd expect the upcoming B7 will do better. The teaser from BMW and Alpina doesn't indicate when the new model will debut, but we'll eat our proverbial hat if it doesn't happen in Geneva. Related Video:
