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.

Lewis Hamilton scores a record 80th pole in Japan, Vettel ninth

SUZUKA, Japan (Reuters) - Formula One leader Lewis Hamilton seized a record-extending 80th pole position at the Japanese Grand Prix on Saturday, timing his sole flying lap to perfection while Ferrari's Sebastian Vettel managed only ninth. The Mercedes driver, in dominant form all weekend at the Suzuka circuit, pumped in a one minute 27.760 second lap on the super-soft tires while it was still only just spitting with rain. Vettel and Ferrari teammate Kimi Raikkonen, who went out on intermediate tires in the final part of qualifying with the track still dry, lost time coming back in to fit the super-soft tires. The German then made another mistake on his first flying lap and was unable to get another one in as the intermittent drizzle turned into a full-blown shower that drenched the track. Meanwhile, Hamilton – who along with team mate Valtteri Bottas had gone out straight away on the super-soft tires to beat the rain – was lighting up the timing screens. "The team have done an amazing job this weekend, and the call that we made for Q3 was probably the most difficult," said the Briton, joined by Bottas on the front row after the Finn completed a second successive Mercedes front row lockout. "It's so difficult when the pressure is on to make the right call but that's the big difference between us this year and that's why we're the best and the team deserve it," added Hamilton. Vettel trails his fellow four-times champion by 50 points in the standings with just four races left after Japan. His hopes are fading fast and he needs a huge stroke of luck now to reignite his challenge. "Obviously it's not the position we deserve to be in," said the 31-year-old. "I think we have better speed than ninth but we'll start there and see how it goes. "Anything can happen tomorrow. Tomorrow is a new day." RICCIARDO FUMES Vettel's misfortune allowed 21-year-old Dutch driver Max Verstappen to qualify third for Red Bull. "We have a bigger chance now to be on the podium," said Verstappen, doubting that he would need to worry too much about the others' title battle: "Is it still a battle? I'm not sure," he said. While the Dutchman celebrated, teammate Daniel Ricciardo was left hoarse with anger after a power unit problem sidelined him during the second phase of qualifying before he had set a time. The Australian, as a consequence, is set to start 15th. "I just can't catch a break," said Ricciardo, who is leaving Red Bull for Renault at the end of the year.
