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.

Daimler, Toyota, BMW to lead $10-billion hydrogen investment

Daimler, BMW, and Toyota are leading a group of 13 companies pledging to invest more than $10 billion during the next five years to spur enough infrastructure-building and technology advancements to get more of the general public to buy hydrogen fuel-cell vehicles. The automakers, which also include Honda and Hyundai, as well as companies such as Shell, AirLiquide, Linde Group, and Total SA, are part of what they're calling the Hydrogen Council. The group made its announcement in Davos, Switzerland, on Tuesday. The Hydrogen Council will pledge to accelerate its rate of hydrogen-related investments, which currently stand at about $1.5 billion annually. The coalition says its work represents a continuation of the 2015 Paris Agreement, in which many of the companies agreed to address the issue of climate change. The group says that hydrogen, which emits water vapor when used in fuel-cell vehicles, "can play an important role in the transition to a clean, low-carbon, energy system." The Hydrogen Council also vowed to push global governments to accelerate public investment in hydrogen-related infrastructure. Relative to other drivetrain technologies, hydrogen fuel-cell vehicles are in their relative infancy in terms of adoption because of the high cost of both building fuel cell vehicles and setting up a hydrogen-refueling infrastructure. Toyota is the only automaker that sells a production fuel-cell vehicle in the US. The Japanese company, which introduced its Mirai domestically in late 2015, sold 1,034 of them in the US last year. Daimler subsidiary, Mercedes-Benz, used Tuesday's announcement to remind people that it would start selling its GLC plug-in hydrogen fuel-cell crossover this year. There are only 33 publicly accessible hydrogen refueling stations in the US, including 30 in California, and one each in Connecticut, Massachusetts, and South Carolina, according to the US Department of Energy. By comparison, there are more than 15,000 electric-vehicle charging stations with almost 40,000 outlets in the US.

Alpina D3 Bi-Turbo torquing its way toward Frankfurt

Few tuners benefit from the kind of factory support that Alpina does, giving the pseudo-aftermarket firm nearly as much official status as BMW's own M division. And this is its latest product.
Set to debut, as expected, at the Frankfurt Motor Show this week is the new Alpina D3 Bi-Turbo, which you can consider, for all intents and purposes, the diesel M3 that BMW never built. While the outgoing D3 (which was Alpina's best-selling model) used a four-cylinder engine, Autocar reports that the new model packs a 3.0-liter, twin-turbo inline-six diesel to drive a respectable 345 horsepower but a mammoth 516 pound-feet of torque to either the rear wheels or all four through the optional availability of xDrive. (European buyers will also be able to choose between sedan and wagon bodystyles.)
The engine is the same as you'd find in the XD3 and D5 (Alpina's diesel performance versions of the X3 and 5 Series, respectively), but in the lighter 3 Series form can propel the D3 Bi-Turbo up to 62 miles per hour in 4.6 seconds and on to an Autobahn-crunching top speed of 173 mph. And as per Alpina tradition, visual cues are minimal, with a subtly optimized aero kit and 19- or available 20-inch alloy wheels. Unfortunately, the 7 Series-based B7 is the only Alpina we get on this side of the Atlantic, but an oil-drenched performance enthusiast can dream.
