Mercedes plotting E-Class Maybach, next A-Class for the US?

Mercedes-Benz has opened 2015 by hinting at a host of new products. Dieter Zetsche nudged the idea that there'll be a Maybach-branded SUV. AMG chief Tobias Moers told Motor Trend that "We want to be seen by the public on the same level as the other sports car maker in Germany" when asked if his crew was working on a car to rival the Porsche 918 Spyder. That and a few other tidbits have people thinking that we'll eventually see some sort of celestial AMG supercar. The latest handful of hints came from Mercedes USA CEO Steve Cannon during an interview on the marque's move to Atlanta. Cannon told Automotive News that we'd "see more from the Maybach brand," leaving the impression that there "could" be an E-Class draped in the superluxury trim. If such came to pass, there's plenty of pricing room between the E and the S-Class to slot a higher trim in. The top non-AMG E-Class starts at $62,350, the S-Class opens the bidding at $94,400. Even if you slapped the E-Class with the $23,000 premium it takes to make an S600 a Maybach S600, you've still got plenty of breathing room between the midsized and full-sized sedans. At the antipodal end, Cannon told AN that we could get a front-wheel-drive Mercedes smaller than anything here right now. That leaves the A-Class, since we've already got the B-Class. Getting the next-gen A-Class here would help with CAFE numbers, and since it will be built in the new factory in Aguascalientes, Mexico it won't have far to travel to get here. We're told it won't be like the current car, however; Cannon said, "The A-Class will change from what you have seen and from what you are used to." We hope that's a good thing, because we really like the current car. Related Video:

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.

VW, Fiat, Mercedes could be CNG winners in Europe

Fiat ads in the US try to play up the exotic, sexy side of Italian culture. On the home front in Italy, however, passenger-vehicle sales are marked by something less edgy and quite a bit more practical: the growth of compressed-natural-gas (CNG) powered car sales. In fact, Italy is leading a group of European countries where CNG sales are on the upswing and may be benefiting automakers like VW, Fiat and Mercedes-Benz, according to Automotive News. VW started sales of its Golf TGI natural-gas vehicle this year – the company's fourth in Europe – while Mercedes-Benz added a natural-gas B-class model. Fiat accounts for about 50 percent of CNG vehicles sold on the continent. In all, Europe's CNG sales through September totaled about 67,000, up seven percent from a year earlier, Automotive News Europe says, citing research firm JATO Dynamics. And the number of CNG vehicles on Europe's roads could jump tenfold within the next decade. The draw is a combination of lower refueling prices and a CNG drivetrain that typically emits less CO2 than diesel vehicles. As for Italy, about five percent of new-vehicle sales are CNG. To put that into perspective, hybrids, battery-electric vehicles, plug-in hybrids and diesels combined to account for about 4.2 percent of US vehicle sales last year.
