Daimler CEO Zetsche answers 'Most likely' to question of a Maybach SUV

When Dieter Zetsche was asked about the possibility of getting Maybach, the reimagined Mercedes-Benz ultra-luxury sub-brand, into the premium SUV game, the Daimler CEO reportedly told Auto Express, "Most likely." Those two little words aren't a firm answer – let alone an indication of timing – but we wouldn't be shocked to find out Mercedes is already working on one. Range Rover has gone even more upscale, the Bentley Bentayga is coming this year, as will the Maserati Levante. Rolls-Royce is deciding on an SUV this year (we think it's only a matter of time before they say "yes"), the Lamborghini Urus is still expected in 2018, Aston Martin is raising funds to build a crossover, and there have been rumors of a BMW X7 and Audi Q9 for years. Point being, everyone is busy writing their own invite to this ultra posh party. The latest comments would appear to put to rest any will-they/won't-they questions around a high-riding Maybach offering. There were rumors last summer that a GL-Class SUV (a model range shortly to be known as GLS-Class) with revamped styling and lots of luxury touches would join the top-tier sub-brand, but then in November, Mercedes' global head of sales and marketing told Automotive News, "I don't want to categorically rule anything out, but at this stage we have no plans for it [a Maybach SUV]." If and when a Maybach utility does become official, we'll only be picking up where we left off with the brand's previous incarnation: a GL-based Maybach was rumored way back in 2007.

Child cobalt miners: Automakers pledge ethical minerals sourcing for EVs

BERLIN - Leading carmakers including Volkswagen and Toyota pledged on Wednesday to uphold ethical and socially responsible standards in their purchases of minerals for an expected boom in electric vehicle production. Demand for minerals such as cobalt, graphite and lithium is forecast to soar in the coming years as governments crack down on vehicle pollution and carmakers step up their investments in electric models. To cover its plans for more than 80 new models by 2025, Volkswagen alone is looking for partners in China, Europe and North America to provide battery cells and related technology worth more than 50 billion euros ($59 billion). Talks with major cobalt producers, including Glencore, at VW's Wolfsburg headquarters last week ended without a deal. More than half of the world's cobalt comes from the Democratic Republic of Congo, a country racked by political instability and legal opacity, and where child labor is used in mines. On Wednesday, a group of 10 leading passenger-car and truck manufacturers announced an initiative to jointly identify and address ethical, environmental, human and labor rights issues in raw materials sourcing. The partnership dubbed "Drive Sustainability" consists of VW, Toyota Motor Europe, Ford, Daimler, BMW, Honda, Jaguar Land Rover, Volvo Cars and truckmakers Scania and Volvo. The alliance "will assess the risks posed by the top raw materials (such as mica, cobalt, rubber and leather) in the automotive sector," said Stefan Crets of the CSR Europe business network. "This will allow Drive Sustainability to identify the most impactful activities to pursue" to address issues within the supply chain.Reporting by Andreas Cremer.Related Video: Image Credit: Michael Robinson Chavez/The Washington Post via Getty Images Green BMW Ford Honda Jaguar Land Rover Mercedes-Benz Automakers Toyota Volkswagen Volvo Green Automakers Green Culture Electric Scania ethics mining

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.
