Alpina XD3 Bi-Turbo offers facelifted looks, diesel-powered 4.9-sec 0-62 sprint [w/video]

I've always thought it would be fascinating to look at the psychographic data of Alpina's customer base. While the company's high-zoot rendition of BMW 7 and 5 Series sedans makes plenty of sense, I don't quite understand the appeal of the still-expensive tunes, further down the range. Enter the European-only Alpina XD3 Bi-Turbo, which made its debut here in Geneva today. The XD3 has been around for a bit, but this year it's refreshed to coincide with the BMW X3's own nip-tuck. The result is essentially a new front and back fascia on the same, ginormous Alpina wheels that make the brand's products instantly recognizable. For anyone that covets huge diesel performance in a small SUV-shaped package, that's a good thing. The XD3 pushes a whopping 516 pound-feet of torque and 345 horsepower out of its 3.0-liter, biturbo sixer, all good for a 0-62-mile-per-hour sprint of just 4.9 seconds. Which is quick by any measure. Still, the privilege of driving the fast, high-center-of-gravity Bimmer doesn't come cheaply – Alpina would like just over 69,000 euro ($77,000 by today's rates) for each example. That kind of coin will buy a European equal performance in the form of a Porsche Macan diesel, or any number of non-SUV performance rides, too. It takes a special mind, I suppose... Related Video:

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

2015 BMW M3 squares off against Alpina D3 in gas vs. diesel throwdown

There was a time when diesel meant one of two things: This vehicle's owner either wants to save some money at the pump or needs to haul massive loads. It definitely did not mean that the owner of said machine wanted to drive fast, but that perception has slowly but surely been changing over the last several years, with automakers from Volkswagen and Ford to Audi and BMW offering spiced-up versions of their high-compression, turbocharged diesels.
It's that last automaker we mentioned that's the subject of the video you'll see down below. One bright-blue BMW M3 was procured by the Brits at Autocar, and it was lined up against a deep-black Alpina D3 (which we sadly can't buy in the US) in a spate of tests, including acceleration, stopping, sound and lap times on a closed circuit. The results, which we won't spoil for you, were enlightening, and were followed up by personal impressions from the man behind the wheel.
We know you're curious. All it takes to find out which of these 3.0-liter, twin-turbo-powered 3 Series variants came out on top is to scroll down below and watch. You know what to do.
