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.

Race recap: 2016 Australian F1 Grand Prix a rowdy start to season

The three brief Formula 1 tests ahead of the current season belied how much had gone on since the last race in November: Infiniti subbed out for Tag Heuer, Renault is back, the all new Haas F1 team, a revamped Manor, three brand new drivers and two returning drivers, a raft of regulation changes among the newly tilled soil. The four engine manufacturers spent a combined 67 tokens among the 138 in the kitty, Renault using just seven of their 32. The only conclusive proof to come from the annual intermission was the otherworldly capability of Mercedes-AMG Petronas. The Silver Arrows didn't even try the super- and ultra-soft tires, focusing on reliability instead of speed. The result? They ran more than 19 race distances, obliterating the lap totals of every other team. There are certainly a few people who enjoyed the complicated new rolling-elimination qualifying format fast-tracked to approval just a few weeks ago. They were wildly outnumbered by those who thought it was awful, including the same team heads who voted for it. We'd probably have to go back to the debacle at the 2005 Indianapolis Grand Prix for an equivalent fiasco when Michelin pulled its teams over safety fears, leaving six cars out of 20 to qualify. In Australia, within 24 hours of the conclusion of qualifying, the new format had itself been eliminated. Nevertheless, qualifying also taught us what didn't happen over the winter: any other team progressing enough to outduel Mercedes. After admitting that he dropped off after winning the championship last year, then getting questioned in the press for some dubious off-season activities, Lewis Hamilton proved he can still turn it on when he wants to. The Brit smoked the Albert Park track in 1:23.837, more than three-tenths of a second ahead of teammate Nico Rosberg in second place. Ferrari did make strides during the off-season, but only enough to keep the same gap it had to Mercedes last year: Sebastian Vettel lined up third, a half-second behind Rosberg, teammate Kimi Raikkonen another four-tenths back in fourth place. Max Verstappen said Toro Rosso is the best of the rest, the Dutchman taking fifth place in front of Felipe Massa for Williams in sixth and Toro Rosso teammate Carlos Sainz in sixth. Daniel Ricciardo – who wasn't smiling after qualifying – kept Red Bull and its new "Tag Heuer" engines in the conversation with eighth on the grid.
