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.

2014 Mercedes-Benz E63 AMG S Wagon is one hot hauler [w/video]

Mentioned at the debut of the redesigned Mercedes-Benz E-Class back in January, Mercedes has finally pulled back the curtain on the E63 AMG S, which was on display at the New York Auto Show in wagon guise. The 2014 E63 AMG S ups the ante even more from a "base" E63 AMG, improving the car's performance and styling - not that it needed help with either to begin with.
Our favorite S-model upgrade is the added output tweaked out of the 5.5-liter twin-turbo V8 producing 577 horsepower and 590 pound-feet of torque, which represents a substantial gain of 27 hp and 59 lb-ft of torque over the stock E63. In wagon form, the E63 AMG S can run from 0-60 miles per hour in just 3.6 seconds and hit an electronically limited top speed of 186 mph. All 2014 E63 AMGs come with Mercedes' 4Matic all-wheel-drive system, but the S-Model adds in a limited-slip rear differential for improved performance.
Mercedes has made sure that the extra money being spent on the S-Model is instantly noticeable with slightly different design cues and black along with 10-spoke wheels with red brake calipers peeking through. Plenty of silver-chrome and high-gloss black accents finish off the exterior styling, while the interior adds Alcantara on the steering wheel, accent stitching on the leather and contrasting silver seat belts on models with the black interior.

Audi and Mercedes both outsell BMW in January

There won't be any celebrations in Munich this month, as BMW was outsold by arch-nemeses Audi and Mercedes-Benz. The Bavarian company finished behind Audi in January, which took the top spot for the first time since June of last year, Bloomberg reports. Ingolstadt rode high on a 10-percent bump in sales, while Mercedes saw a larger 14 percent increase. BMW, meanwhile, only saw a modest 6.3-percent sales increase last month, thanks in large part to its struggles in China. The company's sales there increased at about half the rate of its chief competitors, with a 7.9-percent jump to Mercedes and Audi's roughly 15-percent increases. Perhaps more worrying for BMW, though, is that this could become something of a trend for the company. According to Bloomberg, issues with Chinese dealers who cancelled orders over sales targets and bonuses combined with what the publication calls aging models, could spell bad news for the German marque. "This looks like a pretty significant decline in growth compared to Mercedes and Audi," Bankhaus Metzler analyst Juergen Pieper told Bloomberg. "I think this will continue during the next few months." News Source: BloombergImage Credit: Matthias Schrader / AP Earnings/Financials Audi BMW Mercedes-Benz
