8 automakers, 15 utilities collaborate on open smart-charging for EVs

We're going to lead with General Motors here. GM is one of eight automakers working with 15 utilities and the Electric Power Research Institute (EPRI) at developing a "smart" plug-in vehicle charging system. Why did we start with GM? Because it's the first automaker whose press release we read that mentioned the other seven automakers. Points for sharing. For the record, the collaboration also includes BMW, Toyota, Mercedes-Benz, Honda, Chrysler, Mitsubishi and Ford. The utilities include DTE Energy, Duke Energy, Southern California Edison and Pacific Gas & Electric. The idea is to develop a so-called "demand charging" system in which an integrated system lets the plug-ins and utilities communicate with each other so that vehicle charging is cut back at peak hours, when energy is most expensive, and ramped up when the rates drop. Such entities say there's a sense of urgency to develop such a system because the number of plug-in vehicles on US roads totals more than 225,000 today and is climbing steadily. There's a lot of technology involved, obviously, but the goal is to have an open platform that's compatible with virtually any automaker's plug-in vehicle. No timeframe was disclosed for when such a system could go live but you can find a press release from EPRI below. EPRI, Utilities, Auto Manufacturers to Create an Open Grid Integration Platform for Plug-in Electric Vehicles PALO ALTO, Calif. (July 29, 2014) – The Electric Power Research Institute, 8 automakers and 15 utilities are working to develop and demonstrate an open platform that would integrate plug-in electric vehicles (PEV) with smart grid technologies enabling utilities to support PEV charging regardless of location. The platform will allow manufacturers to offer a customer-friendly interface through which PEV drivers can more easily participate in utility PEV programs, such as rates for off-peak or nighttime charging. The portal for the system would be a utility's communications system and an electric vehicle's telematics system. As the electric grid evolves with smarter functionality, electric vehicles can serve as a distributed energy resource to support grid reliability, stability and efficiency. With more than 225,000 plug-in vehicles on U.S. roads -- and their numbers growing -- they are likely to play a significant role in electricity demand side management.

2014 Mercedes SL and SLK add small expansion to Takata airbag recall

Mercedes-Benz is the latest automaker to be affected by Takata's massive airbag recall. The company has announced a voluntary recall campaign on a small number of model-year 2014 SLK- and SL-Class roadsters.
In Mercedes' case, 300 vehicles are affected, 200 of which are in the hands of customers. According to spokesperson Donna Boland, the affected roadsters were built between March and April of this year.
The issue, which is apparently the fault of one of Takata's subcontractors, rests with some improperly installed fasteners, which could keep the airbag from performing the way it's supposed to. According to Boland, Mercedes isn't sure what, if any, injuries the recalled airbags could cause, but simply claims there's an increased risk in these particular vehicles. There's been no reported instances of the faulty airbags deploying on a customer and the original issue was found in a production test.

Maybach Pullman, S550 4Matic coming next

Mercedes-Benz officially revived the Maybach name as a sub-brand with the reveal of the luxed-up S600 at the LA Auto Show last week, but that's only the tip of the proverbial iceberg when it comes to the German automaker's new plans for its uber-prestige marque. Motor Trend reports that Mercedes is planning two additional Maybach variants to launch in the near future, both of them also based on the S-Class. First up, we're told to expect the even longer Pullman limousine to launch, complete with Maybach treatment, at the Geneva Motor Show next March – although this model won't necessarily be offered in America. Whether it will or not, the Mercedes-Maybach S600 Pullman will be even bigger, more luxurious and more expensive than the one just unveiled. What is being planned for US customers, however, is an Maybach S550 4Matic. Mating the 4.7-liter twin-turbo V8 to all-wheel drive would be a boon for wintery upscale markets, and is reportedly a more feasible option than trying to pair the V12 to the 4Matic system. As for other model lines, we've heard rumors of a Maybach GL-Class utility in the pipeline, but have yet to receive any such confirmation. Car confirms, however, that we shouldn't expect to see AMG versions of Maybach models. The two are being cultivated as separate pillars atop the Mercedes range – one focused on performance, the other on luxury – and never the twain shall meet. The previous model line did breed a sportier Maybach 57 S, however, and we wouldn't be surprised to see a similar treatment applied to one of the new models should Daimler find there's demand. In related news, MT also reports that a new S-Class Cabriolet is coming around the corner, and that the G550 is preparing to drop its aging 5.5-liter V8 in favor of the GL's 3.0-liter twin-turbo V6.
