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.

BMW dismisses Tesla tie-up talk

Despite recent rumors to the contrary, don't expect to see much collaboration between Tesla and BMW in the near future. Based on some rather prickly statements from the German automaker, Elon Musk might have even burnt some bridges in Bavaria with his latest proclamations. The spat stems from Musk's recent interview with German magazine Der Spiegel where he discusses future collaboration with BMW on "battery technology or charging stations" and the possibility of a battery factory in Germany. But apparently, any future tie-ups are news to the Bavarian automaker. In an interview with the German business publication Wirtschafts Woche, an unnamed spokesperson for the company claims Musk said it all for PR value and swats down most of the statements. BMW has no intention of acquiring Tesla shares, and they aren't working together on any tech. There's not much chance for future cooperation on a battery factory in Germany, either. BMW believes that the cells can just as easily be purchased from suppliers, like other auto parts. The one slight concession is that the spokesperson said that the German automaker would be willing to supply Tesla with carbon fiber. That's not an exclusive offer, though, and the company is open to negotiate such a deal with any interested automaker.

2015 BMW 2 Series Convertible will flip its lid for $38,850

For the most part, they look almost identical to their coupe versions, except that they now boast an electrically folding soft top.
BMW is dropping the top of the 2 Series in early 2015 in the US with convertible versions of the 228i and M235i. They'll make their world debut at the Paris Motor Show later this year and will show their faces on this side of the pond at the 2014 Los Angeles International Auto Show.
