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.

2015 Mercedes-Benz S63 AMG Coupe

Conventional wisdom would dictate that adding more power and several key performance enhancements to an already very good car, like the 2015 Mercedes-Benz S550 Coupe, will end up equaling an even better car. In the case of the 2015 Mercedes-Benz S63 AMG Coupe, conventional wisdom sort of applies, but perhaps not as much as we'd have initially guessed. We'll get into the nitty gritty details in just a moment, but here's the most immediate takeaway we had in our minds as we walked away from this super coupe: The S63 AMG is excellent, but so is the slightly more mundane S550 Coupe on which it is based, and which is priced some $41,000 less expensive than its more powerful sibling. Chew on those figures while we examine what differentiates the two S-Class Coupes. Drive Notes As expected, the single greatest highlight of the 2015 S63 Coupe is its engine. As a powerplant, it's a gem. As a hand-built engineering exercise, its 577 horsepower and 664 pound-feet of torque are just as impressive in real life as they sound when recited from stat sheets. Not that the old CL63 AMG was lacking in power, but the new S63 AMG Coupe boasts 41 more horses and 74 more lb-ft than the outgoing engine. The run to 60 miles per hour takes a scant 3.9 seconds, according to M-B, aided in no small part by the car's 4Matic all-wheel-drive system and other assorted electronic brains deciding where, exactly, all those ponies should be sent. The rear-biased system is tuned to send two-thirds of the engine's power to the rear wheels in a bid to make the car feel more like what performance-minded drivers expect. Top speed is electronically limited to 186 miles per hour, which is plenty fast enough, even in the days of 200-plus-mph sedans from M-B's former corporate cousin Dodge. We didn't get anywhere near the car's maximum velocity, but our brief trips into triple-digit territory were quiet, comfortable and completely free of drama. The seven-speed automatic gearbox responds quickly to requests of your right foot, but the steering wheel-mounted paddles don't change gears as quickly as we'd like when in Manual mode. Controlled Efficiency (which we'd call Comfort) maximizes efficiency, keeping the transmission in higher gears and shifting earlier than when in Sport mode, and we didn't find much fault with the computer's shifting algorithms in either setting.

Mercedes-Maybach GLS could become the most expensive car made in America

Mercedes-Benz International, the German automaker's manufacturing facility near Vance and Tuscaloosa, Ala., already builds the GLS SUV. Autonews reports that the coming ultra-luxe version of the large crossover, the Mercedes-Maybach GLS, will be built in Alabama as well for global markets. The most recent timelines mark the reveal in production or near-production form in China, with sales to commence next year. The next-gen series-production GLS goes on sale later this year. The gilded sub-brand previewed a wild concept last year in China called the Vision Mercedes-Maybach Ultimate Luxury, which blended the tall profile of an SUV with the truck of a sedan on donk wheels. Based on spy shots, none of that fancy will make it to production. Both the Maybach and AMG versions of the GLS ride on fat rubber but look thoroughly traditional. The treasure will be inside. Autonews said China accounts for roughly 75 percent of Maybach S-Class sedan sales. That suggests the GLS in baroque trim will emphasize chauffeured luxury touches like rear captain's chairs and lots of rear legroom. Pricing estimates figure $200,000 to get in the door. That would put the SUV right in line with the Lamborghini Urus and a couple stacks of Benjamins above the Bentley Bentayga, with much the same likely audience. One analyst said, "The ultra-high-net-worth kids want something different, and these ultraluxury SUVs certainly fit that," while another opined on its "appeal to the Kardashians and hip-hoppers, if they want something slightly different to the G-Wagen." A $200K MSRP would also comfortably make the Maybach GLS the most expensive new car built in America, taking the title from the Acura NSX. With a great price comes great power, said to be a twin-turbo V8 with more than 560 horsepower. The coming GLS 450 will make do with somewhere around 360 hp. The Alabama plant, which also builds the GLE, GLE Coupe, and C-Class, is also undergoing a $1 billion upgrade to more than double the size of the facility, making lines for battery production and EQ-series vehicle assembly,
