Tesla only 8th greenest automaker, BMW is best, says Newsweek

We imagine some readers will be surprised by this. Newsweek has just put out its rankings for the top "green" companies in the world, and while Tesla Motors chief Elon Musk can crow about how green his electric vehicles are, the company as a whole apparently falls behind some traditional automakers. Quite a few of them, actually. In Newsweek's Global 500 list of the greenest 500 largest publicly-traded companies in the world, BMW ranked best among automakers at Number 26. Not surprisingly, Toyota was close behind at 35, while Nissan came in at 152. What's a little more puzzling is that Tesla fell behind Ford (178), and General Motors (289). That's a lot of pickups versus a few Model S EVs. Go figure. Then came Hyundai (306) and Honda (316), which are a little more palatable. Tesla? It came in at 431. Newsweek's measurement standards include eight categories that include a lot of verbiage and involve things like energy productivity (which is defined as revenue in US dollars divided by total energy consumption), greenhouse-gas emissions productivity (revenue divided by GHG emissions), water usage, waste levels and something called "green revenue" (revenue derived from products that "contribute positively" to the environment). Newsweek says that its results are reproducable by a third party. Take a look at the list here and find the details on how the numbers are compiled here.

Audi leading rival BMW in worldwide luxury sales race

If you thought competition among the German luxury automakers was hot before, it looks like things are just getting started. For the first two months of the year, Audi has sold more cars than BMW worldwide by just 383 cars.
Audi claims to have sold 242,400 vehicles through February, up 9.3 percent from last year, compared to 242,017 units from BMW, up 8.9 percent, in the same period. While the advantage is tiny, its implications could be huge because Bimmer has been the leader in the premium car segment for the last nine consecutive years. Mercedes-Benz lags behind them somewhat at 229,630 vehicles through February. According to Bloomberg, at this time last year Audi had sold 429 fewer cars than BMW.
The growth is all part of Volkswagen Group's goal to become the world's largest automaker. It currently ranks in second when its heavy truck businesses are considered. The German automotive giant also wants to be the world's leading premium carmaker. "Competition in the premium segment is more intense than ever," said Audi CEO Rupert Stadler to Bloomberg.

New BMW i3-like Visio.M EV concept uses lightweight resin

It's not a new version of the BMW i3, but an updated version of a lightweight concept car from SABIC, BMW, the Technical University of Munich, Daimler and others does bear a certain resemblance to the well-designed plug-in city car. From the black "glass" in the hatch to the angled line tail lights to the up-and-down window line, you can see a sort of family resemblance (see an i3 comparison photo here). And, of course, they both have an electric powertrain. But the changes made to the new lightweight urban electric concept vehicle is more of an exercise in what's possible rather than a way to evolve the i3 and i8 into a broader i family of vehicles. Even so, what we see here is interesting, since SABIC found all sorts of new ways to take weight out of the car as part of the Visio.M (Visionary Mobility) project, which was first announced in 2012. Let's start with the window material, which as you might guess from the quotation marks above, is not made of glass but is instead SABIC's Lexan polycarbonate (PC) resin plastic. The lower weight (the PC helps shed about 29 pounds) adds two miles of range while the PC resin has better thermal conductivity compared to glass and so does even more because the HVAC system can be more efficient. According to SABIC's computational fluid dynamics analysis, an extra 9-10 miles of range, in fact. Without the battery, this concept weighs just 992 pounds. Remember, BMW already made a lot of weight-reduction measures in the i3 thanks to carbon fiber reinforced plastic, so to make the "glass" lighter would only help boost efficiencies on a production vehicle that uses a resin like this. Read more below. SABIC's LEXAN™ resin delivers weight savings and thermal efficiency for new ultra-lightweight electric car concept developed by BMW-led Visio.M Consortium Munich, October 20, 2014 Today, at the Technical University of Munich (TUM), BMW, Daimler, TUM scientists and a consortium of industry participants showcased a lightweight urban electric concept vehicle with various advances, including an all-plastic design of the car's windows. The windows are made of LEXAN resin, a polycarbonate (PC) material, and coating technologies from SABIC, a leading developer of PC glazing for automotive windows and many other thermoplastic solutions for the automotive industry.
