Project Maybach is an absurd, awesome off-road electric coupe

Mercedes has created some mighty unusual concepts for the Maybach luxury brand. The Exelero high-speed test car and the Ultimate Luxury SUV sedan come to mind. But the Project Maybach, designed in collaboration with late fashion designer Virgil Abloh, may be the wildest yet, being an electric off-road coupe. It's not just the fact it's a two-door off-road coupe. It's the fact that it's a nearly 20-foot-long two-door off-road coupe. And it has very traditional proportions and lines, with a gargantuan front end, and a somewhat less gargantuan rear end. It's squared-off, but in a more elegant, midcentury luxury car way than say, a Hummer. And of course, it has a huge chrome grille and highly embellished taillights, complete with Maybach logos. And yet, this old-school coupe sits high off the ground. It rolls on small, steel-style wheels with chunky tires. It even has skid plates, bolt-on fender flares, rock rails and a roll cage with a roof basket. It's all painted in a matte tan paint that makes it look like a desert-ready expedition vehicle. It's even arguably practical for expedition work. The somewhat spartan-looking interior has tan leather seats that recline fully flat for sleeping. Being an electric car with long areas unoccupied by people, plus that roof basket, it likely has loads of cargo space. On the hood are solar panels that might provide a bit of range, but would at least be handy for recouping some power for accessories. The interior seems to have additional storage bins and tools stowed in special compartments around the cabin. As for the actual performance and range, well, Mercedes has nothing specific. That's not entirely surprising, since this seems to be solely a design exercise. As such, don't expect to see a production model anytime soon. Then again, off-road luxury vehicles are certainly popular. Maybe Mercedes would consider it if there were enough seriously wealthy customers expressing interest. 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.

Aston Martin and Mercedes-AMG formalize technical partnership

The development of a partnership between Mercedes-Benz and Aston Martin has been a long time coming. The news dates back to 2008, and over the five years since was supposed to lead to a rejuvenation of both the Maybach and Lagonda brands. That program ultimately fell apart, but the tie-in was forged afresh in July when the two automakers signed a letter of intent over a renewed partnership. And now that partnership has been formalized.
In a deal just announced, Mercedes-AMG will build a new V8 engine for Aston Martin that will power a new generation of luxury GTs for the British marque, presumably to replace the 4.7-liter V8 in the Vantage. The relationship appears to be similar to the one already in place between AMG and Pagani, only in this case, will involve Daimler taking as much as a five-percent stake in Aston Martin and an observer seat on Aston's board.
The technical partnership is also set to lead to the supply of electric and electronic systems, and could incorporate "additional areas of cooperation in the future." Whether that will include a fresh attempt at reviving Lagonda remains to be seen, as does the future of Aston's long-serving, Ford-based 6.0-liter V12 engine. But for now you can read the full announcement below.
