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

Alpina B4 coupe will be your subtle M4

We're big fans of Alpina here at Autoblog - the BMW tuner has created some seriously delicious products in the past, and recently tuned the diesel-powered 3 Series wagon to create the D3 Bi-Turbo. What we like most about Alpina is how the cars only look subtly more aggressive than stock, yet they pack a real wallop under the hood.
Take this B4 Coupe, recently spotted testing at the Nürburgring. It looks pretty tame compared to the normal 435i, the only visual additions being the Alpina-standard 21-spoke wheels, modified front lip and rear wing spoiler. But under the hood, Alpina is reportedly working on a tuned, twin-turbo straight-six that produces something like 410 horsepower. That means the B4 should be good for a 0-62 time of 4.2 seconds, with a top speed around 190 mph. Rear-wheel drive will be standard, though our spies suggest that Alpina could also use all-wheel drive here in the B4.
We have no doubt that the next BMW M4 will be super hot, but for those seeking a bit more stealth and exclusivity, this Alpina B4 certainly looks the business. Check it out in our gallery above.

BMW adds new entry-level 320i model, priced from $33,445*

Fans of the new BMW 3 Series here in the US have likely been waiting for one of two models to arrive: the new M3 or the diesel-powered 335d. Well... keep waiting just a little bit longer. Here at the Detroit Auto Show, BMW is showing off the new entry-level 320i that will join the 3 Series lineup this spring, and rather than bringing added performance or efficiency, this car is boasting affordability above all. The 320i has been on sale in other markets since the current-generation 3 Series was introduced, but it goes on sale in the US with a starting price of $33,445 (*)including $895 for destination, which is $3,405 less than the current starting price of BMW's well-liked sedan.
In other countries, the 320i uses either a 1.5- or a 2.0-liter inline-four (both turbocharged), and the US version of the car will be getting the latter engine producing 180 horsepower and 200 pound-feet of torque. For comparison, the current 328i, which uses this same engine, produces 240 hp and 255 lb-ft of torque. As expected, performance of the 320i will suffer with BMW estimating a 0-60 mile-per-hour time of 7.1 seconds, but it still has the same 130 mph top speed as the 328i. Oddly enough, despite the lower output, BMW's expected fuel economy for the 320i equipped with rear-wheel-drive and the eight-speed automatic transmission actually matches that of the current 328i with 23 miles per gallon city and 33 mpg highway, and those numbers are actually lower than the 328i with the manual gearbox.
It sounds like most of the usual 3 Series options will be available on the budget-minded 320i, including the choice of xDrive all-wheel drive, BMW Assist and numerous packages including a Sport pack and Premium pack.
