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.

Mercedes-AMG planning hybrid hypercar?

It used to be that, a few overlapping two-door models aside, Mercedes-Benz and Porsche didn't really compete with one another. That's how the two ended up collaborating on projects like the Mercedes 500 E that put it on the performance sedan map without fear of stepping on each other's toes. But Porsche has grown considerably since then, challenging its Stuttgart neighbor with four-door sedans and crossovers, as well as sports coupes and convertibles. Little wonder, then, that Mercedes has hit back at Porsche with the AMG GT, and there will be many more versions to follow in 911 style. But that may not be the final salvo the Silver Star marque launches at Zuffenhausen. According to the latest bit of speculation and deduction from our friends at Motor Trend, Mercedes-AMG may be planning a hybrid hypercar of its own to take on the Porsche 918 Spyder – not to mention the McLaren P1 and LaFerrari. Solid information is sparse at this point, but after speaking to AMG chief Tobias Moers, MT speculates that the new flagship will likely be mid-engined, with a boosted version of the company's 4.0-liter twin-turbo V8 kicking out between 650 and 700 horsepower, working with a pair of electric motors at the front to deliver tenacious through-the-road all-wheel traction and a combined output in the thousand-horsepower range. There is the possibility, though, that Mercedes could go after the latest hybrid hypercars with a flagship version of its just-launched AMG GT, packing a similar powertrain setup as the ultimate evolution of the breed. Other GT versions will likely soon include a GT3 racing model, a Black Series version and a roadster – following a similar path taken not only by the 911, but also by Benz's previous halo supercars like the SLR McLaren and SLS AMG.

Infiniti went out of its way to make the QX30 not a Mercedes

You can complain all you want about perceived badge engineering when a company (like Mercedes-Benz) sells a platform to another brand (such as Infiniti). The reality is that most buyers won't know the difference, and they won't even realize their Infiniti is really a Mercedes underneath or that their neighbor's GLA has the same basic parts as the QX30 they just bought. What's weird to me isn't that sameness, but the places where the two cute little utes differ. These two vehicles, which are more like tall hatchbacks, use the same Mercedes 2.0-liter turbo four and seven-speed dual-clutch transmission. Infiniti adds its own throttle and transmission calibrations. The suspension design is the same, although there are tuning differences. Both come standard with front-wheel drive, with all-wheel drive an option. Fuel economy matches for the FWD models, while the AWD Infiniti lags behind the Mercedes for some reason. So they're very similar despite their different looks. And design makes sense as a point of differentiation. Frankly, they go further than a lot of vehicles on shared platforms do – further, in fact, than the upcoming Nissan Navara-based Mercedes X-Class pickup does. The QX30 has its own sheetmetal and glass to separate it from the GLA-class. You probably think one looks better than the other. If you know where to look, the signs of sameness are obvious. Most major systems and pieces are shared, like the steering wheels (with different center covers), most switchgear, and things like interior and exterior door handles. Shared parts are fine as long as the parts are good ones. On that note, how many Tesla buyers realize their steering column and stalks, plus the window switches, come from Mercedes? And does that actually matter? We'd argue no. About those differences. Many are functional, like the fact the Infiniti does not carry over the Benz's Brake Hold feature – when you roll to a stop in the GLA (or any other Benz), pressing the brake pedal firmly applies the electric parking brake until you hit the gas to move again. The QX30 has an electric parking brake, but no Brake Hold feature. Someone used to driving Mercedes models will look a bit silly standing on the brake pedal to no effect. Ask us how we know. The Mercedes gauge package is carried over, but with the Infiniti font. Makes sense, although it's off-putting at first if you've seen the original, prompting a weird deja vu. Circular dash vents are replaced by rhomboid ones.
