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.

Senior VP Hildegard Wortmann says BMW's electric journey is just beginning

Anyone who questions BMW's effort or sincerity on electrified vehicles should have a chat with Hildegard Wortmann, the German automaker's senior vice president over product management for automobiles and aftersales. I was fortunate to do just that at the Detroit North American International Auto Show earlier this year. ABG: Where might BMW go with electrified vehicles beyond your i3 urban EV and i8 high-performance hybrid sports car? "That [regulatory] train has left the station" - Hildegard Wortmann HW: I think a big advantage is that we now have two bookends: BMW i [green] and BMW M [high performance]. We can use those bookends to foster the BMW brand in total. Are electrified vehicles the answer to CAFE and European regulations? Is that the future? We don't know, but that [regulatory] train has left the station. To achieve all of these regulations worldwide, there is no way to do it without electrification. That is why the activities of BMW i are not just to launch new products. They are our build-up in competence for learning and gaining experience in electrification. We will use those learnings for the total BMW brand. Technology-wise, we now have a really good understanding of what to do, what not to do, how to work with this and how to get a lot of learnings from the infrastructure and everything that goes with it. And depending on how quickly the market takes off, we can scale it and use it across the range. We will use the competence we will have in vehicle electrification for more than just BMW i. There will be other derivatives and electrification of other products. ABG: Do you see BMW offering pure EVs with larger batteries for greater range? HW: That's a big feature of the Tesla. The question is to find the best balance [of range vs. battery size, weight and cost]. On the i3, we tried to have the right balance between how much range customers need for daily driving and how much battery we put in there. The market will show us. We have over a million kilometers driven by consumers in the Mini E and ActiveE and a fairly good understanding that those people are not driving that much. Putting a really big battery with all that weight into a car that is meant for urban mobility does not make sense. ABG: What about extended-range EVs beyond the i3's optional small range extender engine? "This whole EV movement is in its very early stages." HW: This whole EV movement is in its very early stages.

2013 Nissan GT-R and 2013 Alpina B6 mix it up on track and street

Here we have Autocar making an unforeseen comparison: the Nissan GT-R against the Alpina B6 at Brands Hatch and on public roads. Steve Sutcliffe clobbers the circuit in the 3,828-pound, all-wheel-drive sports car, then sees how well the 4,114-pound, rear-wheel drive grand tourer does against it.
Sutcliffe says there are quite a few similarities between the two cars, but that's really only on the spec sheet. The Nissan's got two turbos attached to its 3.8-liter V6, 542 horsepower and 465 pound-feet of torque. The Alpina's got two turbos attached to its 4.4-liter V8, 532 hp and 528 lb-ft. But one's brief is to be a monster on the track, the other on the boulevard, and if there's anything the video demonstrates, it's each car's focus.
