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.

2016 Japanese Grand Prix | Hamilton faces the beginning of the end

We're told the Japanese mamushi viper haunts the undergrowth around Suzuka. If the pit viper attended the weekend's Japanese Grand Prix, it avoided human visitors but it put a nasty bite on Lewis Hamilton's championship hopes. The Briton, lined up second on the grid next to Mercedes-AMG Petronas teammate Nico Rosberg, flubbed his start. By the end of Turn 1 Hamilton was in eighth. Hamilton didn't suffer alone. The beginning of the race was a melee; many of the leaders got caught out either by the damp track or by having to swerve around slow starters. Only Mercedes' Nico Rosberg and Red Bull's Max Verstappen took off clean. The German rolled up another lights-to-flag victory despite the pass-happy race happening behind him. Rosberg was as unbothered by the Dutchman in second place as he was by the official Formula 1 camera feed. Verstappen didn't have much work to do until the final ten laps of the race. Thanks to the Mercedes team's strategy – or Ferrari waiting too long to pit – Hamilton got up to third on Lap 36 of 53. Unable to make a DRS-enabled pass on Verstappen down the front straight toward the end of the race, the Mercedes driver took a creative line through Spoon corner. Closing in down the back straight, Hamilton jinked inside to try a pass through the final chicane. Verstappen moved over in the braking zone while Hamilton was still behind him, closing the door on the move. Hamilton protested over his team radio, but seemed resigned to a third place finish after the incident – he didn't try any more passes in the final laps. The Ferrari duo of Sebastian Vettel and Kimi Raikkonen crossed the line fourth and fifth, respectively, in recovery drives after penalties. The scuderia tried an aggressive final stint after Hamilton successfully undercut Vettel in the pits. Ferrari put Vettel on the soft-compound Pirellis so he could hunt the Mercedes, but after a few laps of close pursuit the tires gave up and Vettel fell back. Daniel Ricciardo couldn't get comfortable in his Red Bull the entire weekend. The Aussie finished where he started, in sixth place. Sergio Perez and Nico Hulkenberg followed the Red Bull home in two-up formation for Force India, Williams doing the same in the final two points-paying positions with Felipe Massa and Valtteri Bottas. Rosberg's 23rd career victory – his ninth of the season and first ever in Japan – puts him 33 points ahead of Hamilton in the Driver's Championship with four races left.

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
