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 Singapore Grand Prix Race Recap | Setting the stage for the final rounds

The Singapore Grand Prix always features a safety car. This year the nation-state got caution out of the way early: seconds after the lights went out, Toro Rosso's Carlos Sainz collided with Force India's Nico Hulkenberg, sending Hulk into the wall minus a wheel and some bodywork. The safety car led the field for three laps, then ducked into the pits so abruptly that a track marshal was still retrieving debris as race leader Nico Rosberg hit the throttle down the front straight. Rosberg avoided the pedestrian on his way to a two-second lead over Daniel Ricciardo in the Red Bull, Lewis Hamilton in the second Mercedes-AMG Petronas, and Ferrari driver Kimi Raikkonen. On Lap 8 of the 61-lap race Mercedes engineers warned Rosberg and Hamilton about brake management. Rosberg had no trouble until the waning laps of the race, his teammate inadvertently the cause. Raikkonen got ahead of Hamilton on Lap 33 while Hamilton nursed his car. Trying to get Hamilton back in front of the Ferrari, Mercedes pitted Hamilton on Lap 46 and also ordered him to turn his engine up. Ferrari debated for a lap about whether to bring Raikkonen in, finally issuing a last-second order to pit. The Finn emerged behind Hamilton, but executing the trick to get Hamilton back into third gave Ricciardo breathing room in second place. Red Bull brought Ricciardo in on Lap 48 for a set of super soft Pirellis. Returning to the track 25 seconds behind Rosberg, Ricciardo cut from one to four seconds out of that gap on every lap. By Lap 59 the Aussie was little more than a second behind the German. Had the race gone three more laps, Ricciardo might have pulled off the upset. This time Rosberg stayed in front to win his third race in a row and his first victory in Singapore, all in his 200th grand prix. Ricciardo and Hamilton completed the podium; Raikkonen claimed fourth. Sebastian Vettel wrangled an incredible fifth place after starting last; the German set the worst time on the grid when his suspension broke in Q1. Max Verstappen, having lost places at the start due to wheelspin again, recovered for sixth. Fernando Alonso made the most of his McLaren with seventh, ahead of Sergio Perez in the lone remaining Force India, a resurgent Daniil Kvyat in the Toro Rosso, and Kevin Magnussen scoring Renault's second points finish of the season. Hamilton has not had a good time of it since the end of the summer break – engine troubles in Belgium, a botched start in Italy, and zero rhythm in Singapore.
