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.

2016 Mercedes-AMG G65 coming to US this fall, priced from $217,900*

The top end of the luxury SUV market keeps edging northwards. Where the prospect of spending six figures on an off-roader once seemed unthinkable, a new class at the top end of the segment has emerged with prices exceeding $200k. And now American buyers will have another choice on their hands with the arrival of the Mercedes-AMG G65. The flagship model of the Gelandewagen range, the G65 is based on Benz's immortal SUV that's been produced in Graz, Austria, since 1979 and (officially) arrived in the US in 2002. But while the G-Class has been offered in a number of specifications even here in America – up to and including the eight-cylinder G63 AMG – the top-of-the-line G65 was kept away from these shores. But now the German automaker has announced it's bringing its ultimate sport-ute to American showrooms. Distinguishing the G65 from 'lesser' G-Wagens is its 6.0-liter twin-turbo V12 – the same essential unit that already powers the S65 coupe and sedan, SL65 roadster and the Pagani Huayra – producing in this application 621 horsepower and 738 pound-feet of torque. That's said to be enough to shuffle the big ute up to 60 in just 5.3 seconds. Of course all that power and prestige comes with a price, and as you might have guessed, it's astronomical: $217,900 plus $925 delivery, to be specific. In that ballpark, it'll be tangling with the new Range Rover SVAutobiography and the upcoming Bentley Bentayga. Not even the top-of-the-line, $157k Porsche Cayenne Turbo S wears that high a price tag. Look for the Mercedes-AMG G65 to reach showrooms in November, and check out the ever-so-slightly facelifted G-Wagen in our gallery above, live from New York.

Starting at an MSRP of USD $217,900, this model joins the G550 and G63 AMG in the U.S. lineup in November 2015. It is also the fourth exclusive AMG model priced above $200,000: SL65 ($215,250), S65 sedan ($222,000), and S65 Coupe ($230,900). Powered by a V12 bi-turbo engine, the G65 AMG delivers 621 hp and 738 lb-ft. of torque, with an estimated 0-60 mph acceleration in 5.3 seconds. The G-Class is the only off-road vehicle in its class to combine the electronic traction system 4ETS with a transfer case and three 100% differential locks.

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.
