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.

Daimler boss says VW scandal dings 'Made in Germany' brand

"Made in X." "A product of X." "From X with pride." Virtually every country on the globe attaches some kind of moniker to the products it sells, and they generally carry a lot of weight. A Swiss-made watch is better than one made in China, and an Italian suit is better than something from Vietnam. For cars, the "Made In" label is a bit trickier, and is certainly open to opinions. That doesn't mean there isn't some nationalistic pride in play. With the Volkswagen diesel emissions scandal, there's real concern among at least one German that Wolfsburg has caused serious damage to the "Made In Germany" label. Daimler-Benz boss Dr. Dieter Zetsche called VW's use of emissions-cheating devices "a blow to our industry." "I think a strength of 'Made in Germany' and of the German auto industry is a perception that these are reliable brands and you can trust them," Zetsche said at a meeting of the Economic Club of Washington, The Detroit News reports. "It's up to us to rebuild that trust because we haven't done anything wrong." Zetsche also took the opportunity to reaffirm that Mercedes-Benz has never and will never use defeat devices in its vehicles. The exec also said he doesn't think the company has lost any sales from VW's cheating.

A weird end to a weird F1 season | 2016 Abu Dhabi Grand Prix recap

The 2016 Formula 1 season ended with a bang that came from a direction no one expected. Lewis Hamilton put his Mercedes-AMG Petronas on pole position and then got away clean to start the race. Teammate Nico Rosberg did the next best thing, lining up in second and following right behind Hamilton for most of the race. Other than Rosberg's wicked pass on Red Bull's Max Verstappen to retake second place on Lap 20, things stayed all quiet at the front. Come Lap 32 of the 55-lap race, however, observers began to wonder why Hamilton was driving so slow. The Brit, working every trick he could think of to win the Driver's World Championship instead of just the race, dogged it out front trying to push Rosberg back into the chasing mix of Red Bulls and Ferraris. Over the next 15 laps Hamilton's race engineer repeatedly radioed ideal lap times. Hamilton only occasionally hit the times until finally saying, "I suggest you let us race." When the one-stopping Sebastian Vettel blasted his Ferrari from sixth to third, nosing up to Rosberg's gearbox, Mercedes team honcho Paddy Lowe got on the radio to instruct Hamilton to go faster. Hamilton replied that if he wasn't going to win the championship he didn't care about winning the race. Hamilton repeatedly zoomed through the first sector to keep everyone behind, then clogged up the works through Sectors 2 and 3. The problem with his plan was that the Red Bulls in fourth and fifth couldn't get close enough to threaten the trio at the front; even if Vettel had got by Rosberg, Rosberg would still win the Championship with a third-place finish. As it happened, Rosberg finished second behind the disconsolate Hamilton. Vettel took third, followed by Red Bull drivers Verstappen and Daniel Ricciardo, then the second Ferrari piloted by Kimi Raikkonen in sixth. Nico Hulkenberg took seventh, beating Force India teammate Sergio Perez for the last time as an intra-team rivalry. Felipe Massa closed his F1 career with ninth place in a Williams chassis that he got to take home as a gift from the team. Fernando Alonso scored the final point for McLaren, a touch of sweet for the team after the bitterness of Jenson Button retiring on Lap 12 with suspension damage. Rosberg's second place earned him 385 points for the season, enough to take the World Driver's Championship from Hamilton by just five points. Some have put the title down to Rosberg's consistency, others to his car's reliability.
