Bmw: M3 on 2040-cars

BMW M2, we're happy to see you

I recently spent some time behind the wheel of the BMW M235i and, well, I didn't love it. Sure, it's a great car, but I just didn't truly bond with it the way I have with previous M cars. What I had hoped for was a proper successor to the 1 Series M Coupe I fell in love with in 2011, but what I got instead was just a sporty 2 Series that didn't exactly stir my emotions in the same way.
But now there's this: the honest-to-goodness BMW M2. Previously, spy photographers captured a development-mule M2, but this is the real thing, in its full prototype body. Notice the aggressive front fascia that mimics the M3/M4, the more more robust wheel/tire package, and the M-standard quad exhaust outlets around back. This thing sure does look the business.
Details are slim as of this writing, but rumors suggest power will come from BMW's now-ubiquitous N55 turbocharged 3.0-liter six, with output somewhere in the 360- to 380-horspower range. The seven-speed M dual-clutch transmission seems like a good fit here, too. As does a six-speed manual transmission (here's hoping).

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 M3 and M4 leak ahead of Detroit debut

Images of the overhauled BMW M3 sedan and M4 coupe have leaked ahead of a debut at next month's Detroit Auto Show, along with option sheets and some specs.
Both wear the standard hallmarks of BMW's M division. There's a subtle power dome in the hood, along with the requisite M3/4-branded strakes on the front fenders. The front and rear fascia are more aggressive than what we've seen in the 3/4 Series M Sport package, as well. Split-five-spoke wheels mean the neither car will stand out in the family portrait and those gold calipers, meanwhile, signify what has been rumored for some time - the M3 and M4 will be getting carbon-ceramic brakes.
The cabin is home to the standard suite of M accoutrements, including a new steering wheel and more heavily bolstered seats. Special trim, including carbon fiber, will be available to further set these cars apart from the standard models.
