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 makes the M4 extra special with a huge wing

BMW has all of the bases covered in its lineup, especially when it comes to its 4 Series models. Don't like going to the track? There's the BMW 430i and 440i, which are available as a coupe and gran coupe. Drivers looking for a track-friendly car that can also be used on the road will be steered toward the M4. BMW even built the hardcore M4 GTS for drivers that spend all of their time on a track. Now, it looks like BMW is trying to bridge the gap between the M4 and the M4 GTS with a special-edition model. Our photographers caught BMW testing an M4 with some extreme aerodynamic components around the Nurburgring. With its aggressive front end, massive wing, and sporty rear diffuser, the prototype M4 appears to be similar to the special-edition M4 Competition Sport that BMW released in Spain. The Spain-only special edition was marketed as a softer version of the M4 GTS with less power and usable rear seats. With a similar look and visible rear seats, this prototype indicates a similar track-focused special edition model. Since the M4 is only a few years old, it's unlikely that BMW is testing a new model, but the automaker could be testing aerodynamic components for a refreshed model down the road. A cheaper, more usable M4 GTS, though, would be the perfect car to round out BMW's current lineup. Related Video:

BMW i3 called 'most revolutionary car' since Ford Model T

The Ultimate Driving Machine, or at least one of them, may also be the Ultimate Engineering Success. Consultant Munro & Associates, which specializes in automotive tear-down analysis, pretty much said as much when taking an under-the-skin look at the BMW i3 plug-in. In short, the firm liked what it saw. Presenting at Detroit's Plastic's in Automotive conference this week, Munro CEO Sandy Munro called BMW's first mast-produced plug-in model the most revolutionary car "since Henry Ford's Model T." The car earned big points for its substantial uses of materials that are both lightweight (key for any plug-in's range) and recyclable. BMW has touted these advantages all along. In late 2013, the German automaker went as far as saying its use of carbon fiber reinforced plastic (CFRP) would reduce customer costs related to both repair and insurance. The i3 went on sale in the US last May and, by the end of the year, moved more than 6,000 units here. It sold almost 17,800 The i3 last November also was named the Green Car of the Year at the Los Angeles Auto Show, beating out models such as the compressed-natural-gas-powered Chevrolet Impala B-Fuel and the Audi A3 TDI diesel. Munro made news earlier this week when it offered a free i3 for anyone who bought the master- or OEM-level version of the report, though the report isn't cheap and that offered disappeared once Munro made his presentation. Check out Munro & Associates' press release below. Munro Discusses Groundbreaking Technology Finds from BMW i3 Teardown at Plastics in Automotive Conference; Offers New BMW i3 for Purchasers of Master-level Report DETROIT, Jan. 14, 2015 /PRNewswire/ -- During today's Plastics in Automotive Conference in Detroit, Sandy Munro, CEO of Munro & Associates, Inc., discussed – for the first time publicly – his consulting firm's findings from its extensive deep-dive teardown, costing and benchmark study of the BMW i3 urban electric car. During his presentation, "Deconstructing the BMW i3: Groundbreaking Technology and the Composite Car," Munro discussed the carbon fiber life module, polymer components, recyclability and safety of what he considers to be "the most revolutionary car in terms of creative engineering and manufacturing since Henry Ford's Model T." During the presentation, Munro focused on four crucial aspects of the BMW i3: the manufacturing of its carbon fiber life module; its polymer components; recyclability; and safety.
