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 working on new inline-six engines

Mercedes-Benz will make a return to the inline-six-cylinder engine game, according to a report from the UK's AutoCar. It's not clear what's prompting the phasing out of the current array of V6s.
We'll see the first inline-six from Mercedes in next-generation E-Class, set to debut in 2016. Following that, it'll arrive as part of a mid-cycle refresh for the C-Class in 2017. What's particularly special about the new inline-six is its modular nature, which will allow Mercedes to eventually spinoff three- and four-cylinder options, with the three-pot arriving alongside the new inline-six.
In other news, AutoCar uncovered some details on the next C-Class AMG, which will ditch its excellent 6.2-liter, AMG V8 in favor of a 4.0-liter, twin-turbocharged V8, although we've already told you about that. What we didn't know at the time, though, was that the 4.0-liter would be paired first with a new, seven-speed AMG Speedshift transmission and offer all-wheel drive. AC also reports that a nine-speed Speedshift is in the works.

2019 Mercedes-Benz G-Class vs big luxury off-roaders: How they compare on paper

During our first drive of the 2019 Mercedes-Benz G-Class, the all-new SUV's product manager was asked to identify competitors that might have been benchmarked in its development. The look on his face was about the same as if someone had asked him to recite King Lear in Klingon. As far as Andreas Hoeppel was concerned, the G 550 and AMG G 63 doesn't actually have a rival, or at least something the engineers and designers thought to compare it against. The G-Class is a G-Class, who cares what the other guys are doing? Well, in case you care, we figured we'd plug the new G-Class' specs into the old Autoblog Comparo Generator 3000 (TM) to see how the G 550 and AMG G 63 compare to the Range Rover and its mightiest SVAutobiography Dynamic model, plus the Lexus LX 570 and Bentley Bentayga V8. Frankly, Heir Hoeppel was onto something as each of these is wildly different. But, they do share some common elements: giant size and weight, ultra-lux interiors, and far more off-roading capability than other luxury SUVs offer and any of its owners are likely to ever utilize. Sad. So enjoy this trip down specification lane, and if you're still left hungry, you can always check out our Range Rover comparison or create your very own comparo. Off-Road Clearances and Capability All the fancy off-roading software and special cameras in the world won't do you a lick of good if your SUV is too close to the ground or has low-hanging body work that'll get easily ripped off. As such, check out each of these uber-SUV's ground clearance, approach and departure angles, and wading/fording depths. In this case, the Range Rover has an advantage due to its air suspension that can raise itself into an Off-Roading height that's a whopping 2 inches higher than the new G-Wagen. Sadly for itself, Lexus only provides figures for its air suspension when in normal height. It could match or surpass the Range Rover for all we know (but doubt it). As Land Rover does provide figures for the Range Rover's approach and departure angles in normal and Off-Road height, you can get an idea of just how much clearance the new G-Wagen has without any fancy (and expensive to fix) raising and lowering air suspension hardware. In fact, its departure angle is better than even the Range Rover's Off-Road height. Bentley doesn't provide any such information despite touting the Bentayga's surprising off-roading talents.
