Next Mercedes S-Class stretching into this 600 Pullman limo

To the concern of nobody in particular, Mercedes-Benz will not be re-upping its Maybach line of ultra-luxury limousines. No, instead the German automaker will be stretching its already roomy S-Class, to make this upcoming 600 Pullman version of the decked-out beast.
The car in our new gallery of spy shots is sporting beefy B-pillars and a massive set of rear doors that should allow perfectly graceful ingress and egress from what is likely to be a palatial rear space. (In one photo we can even see a long-wheelbase S-Class in line with the new Pullman, handily exhibiting the size of the new variant.) The exterior modifications are otherwise obscured, though we can guess at revised front and rear fascia and lighting elements, based on both end being heavily taped for these test runs.
It's a good bet that the Pullman will make use of M-B's twin-turbocharged V12 engine, though sources indicate that a hybrid version might eventually be in the offing, as well.

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 previews new C63 DTM racer alongside Edition 1

The new C-Class Coupe will undoubtedly be one of the main points of focus at the Mercedes-Benz pavilion in Frankfurt this year. But the Silver Star automaker will have more than just the base version to showcase. There's be the new AMG C63, and now two additional versions. First up is the Edition 1, the designation Mercedes often applies (in some markets anyway) to launch versions of exciting new models. For the C63 Coupe, the Edition 1 features a raft of upgrades, available in either standard (476 horsepower) or S (510 hp) states of tune. It's done up in one of two exterior appearance packages, in matte gray with either yellow trim or black. The Edition 1 also wears special 19-inch wheels in the front and 20-inchers at the back, ceramic brakes, enhanced aerodynamics package, more chrome and gloss-black trim, and an optimized interior with racing buckets. Alongside the Edition 1, Mercedes will also reveal the new DTM racing model in Frankfurt. And following the teaser sketch released the other day, it's giving us our first proper look at the new touring car right here. The new C63 DTM will replace the existing C-Coupe DTM (as it has been formally styled) that has represented the automaker in its local tin-top racing series since 2012 – winning seven races over the past four seasons, but not a championship yet. If looks are anything to go by, the new racing coupe could be up to the task. Special Model to Market Launch: Mercedes-AMG C 63 Coupe Edition 1: Inspired by Motorsport Affalterbach. Mercedes-AMG is bringing the C 63 Coupe Edition 1 special model to the starting line. The exclusive colour combination in designo Magno Selenite Grey with yellow film coating and black wheels with yellow painted rim flanges reflects the graphic design of the Frankfurt International Motor Show launch version of the Mercedes-AMG C 63 DTM racing coupe which will be used in the DTM next year. The special model is equipped with Performance seats and an aerodynamics package, highlighting its proximity to motorsport. The new Mercedes-AMG C 63 Coupe and C 63 S Coupe are also available as "Edition 1" special models from market launch. The extraordinary combination of exclusive design and equipment characteristics is inspired by the optical appearance of future Mercedes-AMG racing coupes which will compete in the popular DTM series in 2016. Two exterior designs address different customer wishes.
