Dinan S3-R BMW 1M Coupe

I nearly shed tears a few years ago upon learning that BMW was only planning to produce a very limited quantity of its then-new 2011 1 Series M Coupe. In simplest terms, the two-door was a 1 Series fitted with a modified version of the automaker's twin-turbocharged 3.0-liter inline-six, and the running gear (gearbox, driveshaft, axles) from contemporary M3 models. It was also a return to form for the brand. Aggressively short and stubby in stature but packing telltale flared wheel arches that hinted at its potential, the four-seater was a spiritual successor to the original (and much loved) E30 M3 from decades earlier.
After spending a day with the original high-performance 1 at New York's Monticello Motor Club, I declared, "The little coupe with the big flares is old-school retro cool and deliciously fun to drive ... the new BMW 1 Series M Coupe doesn't target boy-racers, it targets enthusiasts." Yet sadly - and despite strong demand - BMW limited the model's production to just one year. All told, only 740 units made it to the States, and each was gobbled up at a starting price of $46,135, a price tag history will show to be a bargain.
Since I had little hope of even driving one again, I deliberately pushed all memories of BMW's 1 Series M Coupe from my mind - until my phone rang recently. On the other end was a representative from Dinan Engineering who wanted to know if I would be interested in driving the company's new S3-R BMW 1M. A quick Google search revealed it to be a heavily modified version of the discontinued 1 Series M Coupe. As if they needed an answer...

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.

ROEV lets you use multiple charging networks with one account

It may be a textbook case of a first-world problem, but any EV driver who doesn't want to carry two or three plug-in vehicle charging station cards when one would do is about to get a little smile on their face. This morning at the LA Auto Show, the new ROEV Association was announced that will let EV drivers carry just the one card. While you would think the all-caps ROEV stands for something, none of the pre-announcement materials nor the website explain it that way. Instead, it seems to just be a play on rove, which makes a lot of sense. There are three charging networks involved in ROEV: Blink, ChargePoint, and EVgo. Conveniently, these are the three largest in the US and have a combined 17,500 public chargers across the country. If you've got an account with one of these three networks, once ROEV goes into effect (expected in the spring of 2016), you'll be able to use that card at any participating charger without signing up for another account. Your personal details are kept private, ROEV says, and the companies coordinate behind the scenes to make it work. Pricing details were not disclosed. Besides the three main charging networks, two automakers are also founding members of ROEV: BMW and Nissan. ROEV says that Audi and Honda have also have already joined the Association and the organization wants to pull in all EV stakeholders to make electric vehicle charging easy. Fans of EV technology will note that ROEV has nothing to do with promoting either the CHAdeMO or the SAE Combo (CCS) fast charging standard. The Leaf is a CHAdeMO car while the i3 uses CCS, for example. The charging networks, of course, provide both kinds of plugs and don't promote one over the other. Tesla and its Supercharger network are not involved in ROEV, but Tesla drivers can, of course, participate in ROEV.
