Electric living with a BMW i3

Rarely in the 27-plus years I've been testing and writing about cars has any vehicle changed this much from my initial impression until I was later able to spend more time in one. Nearly two years ago, I got a brief test drive of the then-new BMW i3 EV on a selection of both flat and hilly, curvy roads west of Los Angeles the day before LA Auto Show press days. My impressions at the time were mixed: polarizing exterior and interior designs but roomy, easily accessible rear cabin; great twisty road handling but somewhat brittle rough-road ride; good performance but annoyingly strong (always on) regenerative braking. And there was no opportunity to test one with the optional range-extender (which BMW calls a "REx") engine. So I wanted an extended experience in a REx-equipped i3, and recently got one. And, I'm here to report that, driving it for a week like I owned it, the quirky i3 soon won me over. The quirky i3 soon won me over. The $42,400 BMW EV's unique, lightweight "LifeDrive" architecture features a Carbon Fiber Reinforced Plastic (CFRP) passenger cell on an all-aluminum chassis. Powered by a 22-kWh lithium-ion battery pack, its 170-hp AC synchronous motor spins out a healthy 184-pound-feet of torque through a single-speed transmission and offers three drive modes: Comfort, Eco Pro (which BMW says adds roughly 12 percent of range) and Eco Pro+ (another 12 percent). The optional rear-mounted 647 cc (0.65-liter) in-line 2-cylinder REx engine drives an electric generator, never the wheels. It increases the sticker price to $46,250 and curb weight from 2,860 pounds to 3,130 lb., and that 270-lb. weight penalty reduces its electric-only range from 81 to 72 miles and EPA-rated combined (gas-equivalent) fuel economy from 124 to 117 MPGe, and slows its 0-60-mph acceleration from 7.0 to 7.8 sec. But it nearly doubles the i3's official EPA-rated total range from an EV-only 81 miles to an EV-plus-gasoline 150 miles. The i3 arrived (from roughly 90 miles away) with its battery depleted but an indicated 75 miles of gas-powered range remaining. Wanting to experience it REx-only at first, I drove it on a 9.6-mile local trip and found little difference in sound or performance from what I recalled from that California battery-only test drive. When I returned home, however, the indicated gas range was just 55 miles, so I had used 20 miles of projected range in less than 10 local miles. My initial impressions were good, with a few quibbles.

BMW Vision Future Luxury Concept is bold and beautiful in Beijing

BMW officially unveiled the Vision Future Luxury Concept today (or is it tomorrow?) at the 2014 Beijing Motor Show, giving the world's media an in-the-flesh look at not only a future design theme for the brand, but a rumored flagship model.
This is a looker in person, thanks to its Pininfarina Gran Lusso Coupe-inspired design, and it's not too difficult to imagine it in production car form, with smaller wheels, larger mirrors and the other minor transformations that take place from drawing board, to auto show and, finally, to assembly line. In general, it seems like there are more than a few parts of this vehicle that are ready for production.
We didn't talk about it in our initial post, but it bears mentioning that this particular concept is wearing an eDrive badge on its backside, indicating that under the Vision Future Luxury's long hood is some form of plug-in-hybrid propulsion. It's anyone's guess as to what engine, battery and motor combinations BMW is playing with, although it does seem questionable whether BMW would launch a PHEV flagship to do battle with a top-rung variant of the Mercedes-Benz S-Class (which will likely use V12 power).

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
