Mercedes GLE Coupe spotted in almost undisguised AMG form

Say what you will regarding the form and function of the BMW X6, the bottom line is that BMW essentially pioneered a winning formula, sloping a roofline onto an existing model to make a new and highly lucrative) derivative. No wonder rival Mercedes-Benz is clamoring to follow suit with models like the one pictured here. Under development for some time now, the model originally slated to be called the MLC and now expected to be dubbed GLE Coupe looks about ready for its big debut. It's based on the replacement for the current M-Class (to be rechristened GLE) but with that vital sloping roofline to make it more rakish. This particular example seems to be an AMG version and was spied with only minimal camouflage around the front and rear bumpers while undergoing testing in snowy climes. That could be the full-on GLE63 AMG performance variant, or the new AMG Sport model destined to debut at the Detroit Auto Show next month. If it's the former, expect it to be packing the same 4.0-liter twin-turbo V8 as the new Mercedes-AMG GT, where it produces either 462 horsepower or 510 depending on spec - ready to take on the X6 M and whatever Audi is preparing to throw at it.

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 moves R-Class production to AM General in Indiana

Go back a decade or two and you'd have seen the SUV market polarizing in opposite directions: hard-core off-roaders like the Hummer on the one hand, and passenger-focused crossovers like the Mercedes R-Class on the other. Now their fates are set to intertwine, at least as far as manufacturing is concerned. No longer producing Hummers, AM General (which designed and originally produced the Hummer) has been assigned the task of manufacturing the R-Class at its underused, 675,000 square-foot Commercial Assembly Plant in Mishawaka, IN – part of metropolitan South Bend. The decision was undertaken to allow Mercedes to free up production capacity at its plant in Tuscaloosa, AL, where it also produces the M-Class, GL-Class and C-Class, and where it will soon begin manufacturing the GLE Coupe. The vacation of the R-Class assembly line could be earmarked to make room for that new slant-roofed crossover (which was originally thought to be joining the Tuscaloosa plant as a fifth model) or could pave the way for another model to reach Alabama altogether. The multi-year arrangement to manufacture the R-Class makes AM General the first manufacturer contracted to build Mercedes-Benz vehicles in the US, but hardly the only one in the world. The G-Class – which could, incidentally, be characterized as the German equivalent of the Hummer – is built on Mercedes' behalf by Magna Steyr in Austria, and the company builds many of its passenger and commercial vehicles for local consumption under joint ventures in the Far East especially. The R-Class was first introduced in 2005, and though it's still built in America, it was removed from the company's US lineup back in 2012. However Mercedes confirms that, since 2013, it has been and remains available exclusively in China. That puts the R-Class in the rare position of being manufactured in the United States by (or now for) a foreign automaker but unavailable for sale here. AM General Selected As Mercedes-Benz First and Only Contract Manufacturer of Vehicles in the United States SOUTH BEND, Ind., Jan. 27, 2015 /PRNewswire/ -- AM General LLC and Mercedes-Benz U.S. International, Inc., today announced that Mercedes-Benz has selected AM General to manufacture the Mercedes-Benz R-Class luxury vehicle at AM General's world-class 675,000 square-foot Commercial Assembly Plant.
