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 GLA250 4Matic Quick Spin [w/video]

Certain expectations come with the name "Mercedes-Benz." We picture cars with luxuriously appointed interiors, fashionable exteriors, Autobahn-worthy performance, and a ride that delivers an optimal balance between agility and outright comfort. Expectations, though, are no friend to the GLA250. This is a car that is deeply confused as to its purpose in life – can it be a proper Mercedes-Benz while still being a reasonably priced, subcompact crossover? After a week behind the wheel, we believe the two are mutually exclusive. Driving Notes The exterior styling is similar to the not-for-America A-Class hatchback, with the only major differences found on the rear end. That means that even with its flashy 19-inch AMG wheels and sport body styling – more aggressive front and rear fascias – the GLA is a stylish piece. We might even call it cute. Considering our 4Matic model's reasonable $34,225 starting price, the interior treatment is both attractive and uses mostly quality finishes. The matte Satin Light Brown Poplar wood ($325) covers a large portion of the dash, while the real metal found on the air conditioning vents is elegant and handsome. There is a lot of plastic in the cabin: It's soft on the dash, and switches to a piano-black finish in spots, but the center console and door finishers don't feel like they came from the Mercedes parts bin. In general, the GLA's cabin feels roughly equal to that of the Audi Q3 and BMW X1 – nice, but a step lower than what we've come to expect from Mercedes. The two-piece, leather-lined seats look great, but even with standard 14-way adjustability, they lack support. The bottom cushion is very flat, and doesn't support the legs. For this author, that's a recipe for near-constant back pain. That said, the chairs do look good, especially in the brown of this test car. The GLA250, like a few other models in the Mercedes range, uses a 2.0-liter, turbocharged four-cylinder, delivering a weak 208 horsepower. It makes up for that shortcoming with 258 pound-feet of torque from 1,250 rpm to 4,000 rpm. On paper, this sounds good, but in the real world, the 2.0T's power is tough to access. That's due more to the shortcomings of the seven-speed dual-clutch automatic than the engine itself. With three modes – Eco, Sport, and Manual – we thought we'd find at least one that could serve up precise downshifts.

2015 Mercedes-AMG C63 S Review

"It's about great cars on great roads." The late David E. Davis, Jr., said this of Winding Road when he took the reins as editor-in-chief in 2006. Our mission at that magazine was to not just review cars, but to describe the emotional experience of piloting brilliant machines down beautiful roads. "The art of driving," per David E. This all comes flooding back into my mind as I pull out of a Shell station onto Angeles Crest Highway, just south of the 210 freeway in La Canada Flintridge, CA. I'm in the 2015 Mercedes-AMG C63 S. I've got a full tank of fuel, the whole day to myself, and I'm staring down one of the finest driving roads in the country. Prior to this moment, I spent two days bombing around the greater Los Angeles area in this sinister-looking C63 S. This car is a villain, and looks appropriately so in black paint with the $750 AMG Exterior Night Styling pack. The C-Class as a whole is far more upscale in this latest generation, with its long hood, cab-rearward design, and short rear deck. "Baby S-Class" is not an exaggeration. Thankfully, the addition of AMG bits don't detract from the new C's more premium aura. Where a BMW M3 just looks like a brash 3 Series, the C63 is more like a C400 with a trick up its sleeve. The 4.0-liter V8 is an exceptional engine. Start the engine, and there's no question you're blessed with the power of AMG. Any worries I had about the new, twin-turbocharged, 4.0-liter V8 not providing enough aural delight are gone, especially with the $1,250 AMG Performance Exhaust. At start-up there's a low, burbly sound quality, typical of a V8. At full throttle, it's loud, angry, and passionate. I will always miss the naturally aspirated, 6.2-liter M156 V8 from the last C63, not only for its noise, but for its character. That said, I eagerly welcome Mercedes' new turbocharged techniques. The 4.0-liter V8 is an exceptional engine. In C63 S guise, the M178 lump makes 503 horsepower and 516 pound-feet of torque, the latter of which comes on in full force as low as 1,750 rpm. That's a ton of power for the 3,935-pound C63. But it never feels like there's too much to handle. Power comes on progressively, and when I mash the throttle on a straight stretch of pavement, the car is composed and controlled. And quick. Seriously quick. Zero-to-sixty-in-under-four-seconds quick. The balance between viciousness and grace is perfectly met in this new C63.
