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 releases 6x6 G63 AMG specs and pics [w/video]

Mercedes-Benz has finally dropped full details on its insane G63 AMG 6x6. The machine puts 544 horsepower to all six wheels thanks to a twin-turbocharged 5.5-liter V8. A seven-speed gearbox shuttles power to the ground via three sets of portal axles, which helps give this machine a full 15.75 inches of ground clearance. By comparison, the standard G63 AMG sits with just 8.27 inches of ground clearance. The extra lift allows this 6x6 to ford nearly 40 inches of water and run massive 37-inch tires. All told, there are five differential locks on this thing, all controlled by a special "locking logic" that provides the best traction possible for any given situation.
The controls offer up three stages of locking, which we can only assume range from JKLOL to OMGWTF. Right now, AMG says this monstrosity is only a show vehicle, but we imagine it wouldn't take much to convince the team to whip up one of your very own. Check out our full gallery and the press release below for all the nitty gritty. While you're down there, you can also check out the video on the machine one more time.

Editors' Picks April 2021 | Honda Accord, Mercedes-Benz E-Class and more

The month of April saw us award Editors' Picks status to a couple mega-luxury vehicles and a couple long-time standbys that recently went through mid-cycle refreshes. We drove plenty of other cars that didn't quite reach the bar for Editors' Picks status — BMW 4 Series, Infiniti QX55 and the Mitsubishi Outlander among others — but the four you'll see below stood out as the best this month. In case you missed our previous couple Editors' Picks posts, hereÂ’s a quick refresher on whatÂ’s going on here. We rate all the new cars we drive with a 1-10 score. Cars that are exemplary in their respective segments get EditorsÂ’ Pick status. Those are the ones weÂ’d recommend to our friends, family and anybody whoÂ’s curious and asks the question. The list that youÂ’ll find below consists of every car we rated in April that earned the honor of being an EditorsÂ’ Pick. 2021 Aston Martin DBX 2021 Aston Martin DBX View 16 Photos Quick take: With attractive styling and a gorgeous yet functional interior, the V8-powered DBX is a legitimate crossover worthy of the Aston badge. Score: 8 What it competes with: Bentley Bentayga, Lamborghini Urus, Rolls-Royce Cullinan, Mercedes-Maybach GLS 600 Pros: Mega style, fantastic driving dynamics, a true and faithful Aston Martin Cons: Very expensive, only average infotainment From the editors: Editor-in-Chief Greg Migliore — “The DBX captures the spirit of Aston Martin in a modern crossover. That's not an easy thing to do. I expected the DBX might look the part, but lack functionality. Or it would be a decent crossover, but fall short of my idea of an Aston. The DBX did neither. It exceeded my expectations and is an entertaining vehicle to drive. The styling is interesting and evocative, and the AMG-sourced powertrain delivers proper performance. I also loaded it up with groceries and a carseat fits pretty well. Mission accomplished for Aston." In-depth analysis: 2021 Aston Martin DBX First Drive Review | A crossover that makes you forget itÂ’s a crossover   2021 Bentley Flying Spur 2021 Bentley Flying Spur V8 View 20 Photos Quick take: There are technically competitors to the Flying Spur, but nothing matches it stride-for-stride in every category. ItÂ’s the Bentley flagship product now, and it flies the brandÂ’s flag with both gusto and excellence. You can't go wrong whether you spec the W12 or V8 either.
