Behind the Scenes of BMW's 'Drift Mob,' Part 2 [w/video]

After spending four days practicing about a dozen drift stunt moves in a parking lot for an upcoming BMW "Drift Mob" internet mini-film, Rhys Millen, Sam Hübinette, Dai Yoshihara, Rich Rutherford, and Conrad Grunewald are finally ready for show time. We are brought to the huge urban traffic circle to see the stunts performed midway through the day to observe for a couple of hours.
The undertaking is massive, with multiple cameras set up, scores of crew members, a helicopter filming from above, a rigged pickup for car-to-car shots, sidewalks lined with security and plenty of curious onlookers, and oh, yeah, a major intersection of a top world city shut down for an entire weekend.
The five drifting legends are nestled in their identical red BMW M235i coupes, which have been modified with special handbrakes but essentially nothing else you can't get on a stock version, and are listening to direction from director Mic Rodgers and stunt coordinator Riley Harper. We're basically given free rein of the set, to shoot the cars, the drivers, and at one point, even hopping in with Yoshihara for one of the admittedly more tame stunts. Even then, the g-forces are so severe that they flip our cameraphone's video recording from landscape mode to portrait. Yes, this is a pretty cool day to be reporting on cars, and as we said during our first installment of our behind the scenes coverage of Drift Mob, we're honored to be the only US media outlet here to tell the tale.

BMW won't build M4 Gran Coupe

Over the last few years, it feels like BMW has looked at its lineup and decided to offer a vehicle in every possible segment that it can find, no matter how small. The company is finally showing some restraint, though, at least when it comes to the high performance M division. For example, don't expect to see an M4 Gran Coupe at your local BMW dealer in the future.
M GmbH sales chief Jörg Bartels told Cars Guide in Australia, "It was definitely considered, but there is no plan to build an M4 Gran Coupe." The sport sedan just wouldn't make financial sense, he said. BMW already builds the M3 and M4 at separate factories, adding a third for such a niche model would be too much. Plus, the M3 already fills out the segment.
If you wanted an M model with a bit more storage space in the back, Bartels dashed those dreams, as well. He said that there isn't an M3 Gran Turismo hatchback in the pipeline, either.

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.
