Mercedes-Maybach SL 680 Monogram Series gives the rich and famous what they want

TOPANGA, Calif. – Give the people what they want, right? Especially if they're extremely wealthy. And possibly famous.  Apparently, the requests for a convertible Maybach from existing owners and/or celebrities were so frequent and insistent that the uber-luxury offshoot of Mercedes-Benz finally decided to give them just that. The 2025 Mercedes-Maybach SL 680 Monogram Series answers the call. While all other Maybachs are based on a Mercedes-Benz, this is the first Maybach to be based on a car developed by AMG: the current-generation SL 55 and SL 63. This presented a greater challenge to engineers than past efforts. Although a sportier Maybach was intended (as opposed to modern Maybach's first drop-top effort, the Maybach S 650 Cabriolet), the SL 680 is, not surprisingly, seeking a much different dynamic end goal than its AMG-only cousins. According to Maybach product manager Hannes Meyer, the far shorter wheelbase than the Maybach norm was a particular challenge in making sure that its convertible offering maintained "the same ease and nearly floating driving experience" expected of the brand. To that end, the Maybach SL shares the SL 63's air suspension and trick AMG Active Control interconnected hydraulically controlled dampers, but the tuning is changed, especially with the rear air springs as the driver sits closer to those. Meyer says the damper valves in particular have a greater range between sportiness and comfort than the SL 63. The steering system is totally Maybach-specific, including a different ratio and more upright front camber, resulting in what Meyer described as a more stable and less aggressive setup than what you'd find in the SL 63.  Before you start looking for a 6.8-liter engine in the Mercedes arsenal, remember that those numbers don't really mean anything anymore. The Maybach SL 680 has exactly the same 4.0-liter twin-turbo V8 as the SL 63 good for 577 horsepower and 590 pound-feet of torque. The nine-speed AMG transmission is the same in terms of hardware, but it has totally different software. In particular, the 2-3 and 3-4 shifts are most different in order to provide a smoother, more Maybach acceleration experience. The 4Matic+ all-wheel-drive system is also shared, but is programmed to have a more balanced front-to-rear power split than the rear-biased AMG. Finally, the exhaust has been retuned. Meyer said that up to 2,800 rpm, the exhaust isn't quieter than what you'd experience in the AMGs, it just has a different tone.

Recharge Wrap-up: Nissan reveals GT-R LM Nismo, NRG plans eVgo expansion

Nissan has officially revealed the GT-R LM Nismo LMP1 car. The hybrid Le Mans racer uses a biturbocharged 3.0-liter V-6 up front to power the front wheels, plus a kinetic energy recovery system for an extra boost. Football fans likely caught a glimpse of the car in Nissan's With Dad commercial that aired during the Super Bowl, but the company has a couple more videos that show the car off quite well provided below. "This is innovation that excites," Says Nismo president Shoichi Miyatani. "Sustainability is at the top of our agenda, and the technical regulations for Le Mans give us the freedom to pursue new ideas in this area." Read more at Green Car Congress, or in the press release below. The NRG eVgo charging network now operates 120 DC fast charging stations in California. 60 of those are "Freedom Stations," offering both CHAdeMO and CCS charging cables, and 52 more of these are in the works. NRG plans to expand the eVgo network to 25 US markets in the next two years (up from the current 10), including chargers in Tennessee, as well as linking cities along the near entirety of the East and West coasts.

As of now, the Supercharger network extends as far north as Edinburgh, southwest to Exeter, and to Maidstone in the southeast, which is just up the road from access to mainland Europe through the English Channel Tunnel. Tesla operates more than 1,600 Superchargers worldwide at over 300 stations, with 129 stations and more than 670 Superchargers in Europe. Read more at Hybrid Cars.

Mercedes-Benz engines with 48-volt systems coming in 2017

As part of a big green push announced yesterday, Mercedes-Benz is jumping into the world of 48-volt power. The company will launch a new family of efficient gasoline engines next year and will begin rolling out 48-volt systems with it, likely in its more expensive cars first. Mercedes will use the 48-volt systems to power mild-hybrid functions like energy recuperation (commonly called brake regeneration), engine stop-start, electric boost, and even moving a car from a stop on electric power alone. These features will be enabled through either an integrated starter-generator (Mercedes abbreviates it ISG) or a belt-driven generator (RSG). (RSG is from the German word for belt-driven generator, Riemenstartergeneratoren. That's your language lesson for the day.) Mercedes didn't offer many other details on the new family of engines. There are 48-volt systems already in production; Audi's three-compressor SQ7 engine uses an electric supercharger run by a 48-volt system, and there's a new SQ5 diesel on the horizon that will use a similar setup with the medium-voltage system. Electric superchargers require a lot of juice, which can be fed by either a supercapacitor or batteries in a 48-volt system. Why 48-volt Matters: Current hybrid and battery-electric vehicles make use of very high voltages in their batteries, motors, and the wiring that connects them, usually around 200 to 600 volts. The high voltage gives them enough power to move a big vehicle, but it also creates safety issues. The way to mitigate those safety issues is with added equipment, and that increases both cost and weight. You can see where this is going. By switching to a 48-volt system, the high-voltage issues go away and the electrical architecture benefits from four times the voltage of a normal vehicle system and uses the same current, providing four times the power. The electrical architecture will cost more than a 12-volt system but less than the complex and more dangerous systems in current electrified vehicles. The added cost makes sense now because automakers are running out of ways to wisely spend money for efficiency gains. Cars can retain a cheaper 12-volt battery for lower-power accessories and run the high-draw systems on the 48-volt circuit. The industry is moving toward 48-volt power, with the SAE working on a standard for the systems and Delphi claiming a 10-percent increase in fuel economy for cars that make the switch.
