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.

Mini might build a sedan because it's running out of shapes

Rumors suggest we could soon see a Mini with a trunk to haul your junk. Autocar cites unnamed insiders who claim the sedan is part of the brand's plan for upmarket growth. There's even a possibility the new model could use the Riley moniker in reference to the Elf (pictured above) from the 1960s, which was a Mini with a tiny trunk. The Mini sedan would use BMW's front-wheel-drive platform that underpins the X1 and Clubman and might share the wheelbase and frontend styling with the Clubman as well, according to Autocar. Mini's execs think the four-door would perform especially well in North America and China, where there's less demand for hatchbacks. Ralph Mahler, vice president of Mini's product management, hinted at the possibility of the four-door to Autocar. "For example, in Asia and the US, the sedan segment is very big. This is very interesting to us, of course," he said. Mahler admits that many people don't know about the Mini-based vehicles with trunks from the '60s, like the Riley Elf, so it would be hard to market the new model on that heritage. This could be the perfect time to add a Mini sedan to the lineup, and it might not be a completely new idea for the brand under its BMW stewardship; a rumor from 2012 shows that Mini's bosses considered a four-door at least once before. The company launched new versions of its Hardtop, Convertible, and Clubman, and even added four-door and all-wheel-drive versions of the Hardtop to further blur the lines between that car, the Clubman, and the Countryman. The next-generation Countryman crossover should debut later this year, and the brand reportedly cancelled the Superleggera Vision roadster and Rocketman compact, as Mini has chosen to go big with its new models and its lineup breadth. There are only so many versions of a hatchback a company can make, and the short-lived Mini Coupe wasn't exactly a huge success. If Mini is going to try a new body style, a sedan actually makes some sense, even if we'll probably prefer the look and practicality of the hatches. Related Video:

Pure black BMW i8 hydrogen fuel cell prototype on the track

Largely coated in matte black paint with just a few touches of dark blue contrast, the BMW hydrogen fuel cell-powered i8 prototype looks stealthy just sitting still. Now, that ninja-like styling is taking to the track in this video to prove that its performance doesn't come with much noise. The quiet hum of the tires and an odd whir from the rear are all that you hear coming. As this i8 prototype picks up speed around the circuit, the sounds that the drivetrain makes just get weirder. When moving slowly, you can pick out the usual whine that's expected from conventional electric vehicles. However at higher velocities, the coupe almost makes a noise like its constantly exhaling. Along with the recently unveiled BMW 5 Series Gran Turismo hydrogen-fueled concept, this sneaky looking i8 is part of BMW's technological push to become a greener automaker. The company is also prototyping a turbocharged engine with water injection and new plug-in hybrid powertrains. Although this low-slung coupe is by far the most attractive of that bunch. We might not be too far away from actually seeing this tech on sale on models bearing the Bavarian brand's roundel, either. Thanks to collaboration with Toyota, the company wants to have fuel cell components ready by 2020, and sales could start early in the decade. Hopefully all of the company's FCEVs look as menacingly great as this i8 by that time, though.
