Mercedes-Maybach Pullman stretches its way to Geneva

Mercedes-Benz is known the world over for producing luxury automobiles, but even among Benzes there's a hierarchy. The S-Class sits at the top of the Mercedes range, the Maybach at the top of the S-Class, and what you see here sits at the top of the Maybach line. It's the new Pullman limousine, and it arrives on the 50th anniversary of the original. Stretching a massive 21.3 feet, the new Mercedes-Maybach Pullman is even longer than the previous Maybach 62 by a full foot, and a good 3.5 feet longer than the standard-wheelbase Mercedes-Maybach S-Class, or two feet longer than the G63 AMG 6x6. In other terms, it's over a foot longer than the Rolls-Royce Phantom EWB, and the better part of a yard longer than even the Cadillac Escalade ESV. Heck, you could just about fit Benz's other flagship, the Mercedes-AMG GT, inside the new Pullman's 14.5-foot wheelbase. As if that's not enough, it also stands 3.9 inches higher than a standard S-Class to the benefit of its imposing presence and interior space. Should you be so fortunate as to be graced with an invitation to step inside, you'd find an interior entirely clad in leather with four seats: two recliners and two fold-down seats facing backwards. Those principal rear seats can recline between 19 and 43.5 degrees and offer an extensive array of individual adjustments to cater just-so to the occupants' individual preferences. Ingress and egress are enabled by larger rear doors that open in front of – instead of next to – those rear seats to enhance the privacy of the traveling dignitaries, who will be able to monitor the state of affairs through the analog thermometer, speedometer and clock mounted in the roof liner. They'll also enjoy privacy thanks to the electrically operated glass partition wall with an 18.5-inch monitor mounted in front of it and a choice of Burmester sound systems. Long the favorite of heads of state and captains of industry, the new Pullman will be unveiled at the Geneva Motor Show now just weeks away. We don't doubt that Mercedes will offer its customers a choice of engine options (as long as they're capable of motivating the new Pullman's assuredly substantial heft), but most suitable to the task will of course be the 6.0-liter twin-turbo V12 with its 523 horsepower and 612 pound-feet of torque.

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.

Ecclestone wonders if F1's upcoming turbo V6s should get augmented sound [w/videos]

While every team on the Formula One grid is worried about making a good showing in this year's championship at the same time as they develop a brand-new car for next year's championship, Bernie Ecclestone and F1 circuit promoters have a different concern: how next year's cars will sound. The current cars use 2.4-liter, naturally-aspirated V8s that can reach 18,000 revolutions per minute and employ dual exhaust, next year's engine formula calls for 1.4-liter turbocharged V6s that are capped at 15,000 rpm and are constrained to a single exhaust outlet. Ecclestone and promoters like Ron Walker believe the new engines sound like lawnmowers and that the less thrilling audio will keep people from coming to races. If Walker's Australian Grand Prix really is shelling out almost $57 million to hold the race, every ticket counts. As a fix, according to a report in Autoweek, Ecclestone "suggests that the only way to guarantee [a good sound] may be to artificially adjust the tone of the V6s."
However, neither the manufacturers nor the governing body of F1, the FIA, think there will be a problem. Ecclestone fears that if the manufacturers "don't get it right" they'll simply leave the sport, but the only three carmakers and engine builders left next year, Renault (its 2014 "power unit" is pictured), Mercedes-Benz and Ferrari are so embedded that it would stretch belief to think they'd leave the table over an audio hiccup - if said hiccup even occurs. And frankly, these issues always precede changes to engine formulas, as they did when the formula switched from V10 to V8; fans, though, are probably less focused on the engines and more on the mandated standardization of the sport and the spec-series overtones that have come with it.
No one knows yet what next year's engines will sound like, but we've assembled a few videos below to help us all start guessing. The first is an engine check on an Eighties-era John Player Special Renault with a 1.5-liter V6 turbo, after that is Ayrton Senna qualifying in 1986 in the Lotus 98T that also had a 1.5-liter V6 turbo, then you'll find a short with a manufactured range of potential V6 engine notes, and then the sound of turbocharged V6 Indycars testing last year at the Indianapolis Motor Speedway. Any, or none of them, could be Formula One's future.
