2014 Mercedes-Benz S500 Plug-in Hybrid for fat cats frugal with fuel

Judging by how long we waited to get a clear shot of the Mercedes-Benz S500 Plug-in Hybrid, you'd have thought hybrid cars were only driven by Terminators and that the technology arrived only 48 hours ago through a wormhole in the Mercedes stand. The newest member of the Mercedes-Benz S-Class hybrid band - joining the S400 Hybrid and S350 BlueTEC Hybrid, it hits notes like a 5.5-second sprint from standstill to 62 miles per hour, up to 19 miles of ion-powered running and uses three liters of gasoline per 100 kilometers in Europe (78.41 mpg US, but our mpg test cycle is different than their mpg test cycle).
The lump up front is a turbocharged, 3.0-liter V6, the lump in back - note the reduction in trunk space - is a pack of lithium-ion batteries that juice an 80-kilowatt electric motor. Other than having four drive options for controlling electric drive and battery usage, it's all S-Class all the time, with leather-covered everything and those mountainous thrones that bring to mind words like "Archduke" and "Papal."

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.

BMW expects China to pass US as its top market in 2013

When you combine two billion citizens, 100 cities with more than a million inhabitants and an economy that's as unrestrained as Jim Cramer on an Adderall binge, China's explosive auto industry growth shouldn't be a huge surprise. Audi already lists the communist country as its largest market, while Mercedes-Benz is expecting it to be there in the next few years. Now, according to a report from Automotive News, BMW is expecting the People's Republic to overtake the United States in sales by the end of 2013.
We already discovered the extent that BMW is going to in establishing a dedicated Chinese stronghold, when we explored BMW's Shanghai-based DesignWorks studio ahead of April's Shanghai Motor Show. And while we argued that DesignWorks Shanghai hasn't really borne fruit, it isn't due to a lack of sales.
BMW China has seen a 16-percent jump in year-over-year sales, lead by a 28-percent gain in 5 Series sales. Part of BMW's growth strategy comes from an ever-expanding dealership network. Remember those 100 cities we mentioned with over one million people? According to Karsten Engel, CEO of BMW's Chinese operations, those 100-million-plus city dwellers don't have access to a premium dealership.
