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.

Mercedes making aggressive plans for Chinese market

Mercedes-Benz is preparing a major product offensive to counteract lagging sales in the Chinese market, aiming 20 new or updated models at the People's Republic in the next two years, according to a report by Reuters. The plan is part of MB's so-called 2020 Initiative, which will see the Stuttgart-based manufacturer dump 2 billion Euros ($2.67 billion) into its Chinese market vehicles in a bid to boost sales to 300,000 units by 2015.
Were it to succeed, China would become the largest market for the Silver Arrow, outpacing Germany and the United States. Leading the charge will be the redesigned E-Class, which is set to launch in China this week. That will quickly be followed by the S-Class, and eventually by the GLA-Class in 2014.
Mercedes has struggled in China, especially relative to its German competition, BMW and Audi. Where Mercedes saw a mere four-percent increase in 2012 sales to 206,150 units, Audi was up a staggering 32 percent, while BMW's numbers jumped 41 percent. While some voices, according to Reuters, accuse Munich and Ingolstadt of boosting their numbers through hefty incentives, the fact remains that Mercedes was just walloped by its competitors last year.

Mercedes-Maybach Pullman is the luxury car for the discerning dictator

For decades, Mercedes-Benz and Mercedes-Maybach cars have been the ride of choice for leaders across the globe, presidents, ambassadors, dictators and despots alike. The Pullman model — a long-wheelbase six-seat variant — has been particularly popular with this select clientele. This week, the German automaker announced the latest version of the car, the Mercedes-Maybach Pullman S650. Essentially, this is a stretched version of the V12-powered Maybach with two rear-facing seats just behind the front row. Mercedes is calling this vis-a-vis seating. There's also a partitioning glass between the front seats and the rear cabin. This is of course to help prevent the chauffeur from learning and spilling any state secrets or plans for plans for secret moon bases. New for this model is a front-facing camera for rear-seat passengers. This allows occupants to watch for any oncoming obstacles, barricades or road blocks. Visually, there's no mistaking the Pullman for another Maybach or really anything else on the road. The car is 21.3-feet long, 4.5-feet longer than the standard Maybach or roughly the size of two and a half Smart Fortwo placed bumper-to-bumper. The requisite 20-inch 10-hole wheels are present and the standard pinstripe Maybach grille has been updated with a slightly new design. The car only comes in S650 trim, meaning it's powered by a 630 horsepower 6.0-liter twin-turbo V12. As expected, the Mercedes-Maybach Pullman isn't cheap. Orders have started, but be prepared to shell out at least $615,000 before adding any custom touches.
