Mercedes surprised Hamilton with this steering wheel message

Lewis Hamilton had much to celebrate at the end of the Abu Dhabi Grand Prix this past weekend. Not only did he win the race in commanding form (the 33rd in his career to make him the fifth most successful in Formula One history), but he also scored enough points (double on the season finale this year) to outpace his teammate and chief rival to win the world championship. Having already been crowned champion in 2008, that makes him one of only sixteen drivers to have won multiple world titles. It's a point his team at Mercedes didn't want him to miss, so on the cool-down lap at the end of the race, his pit crew radioed him the message "default 44" – an instruction that triggered this image to appear on the display in the middle of his steering wheel. Apparently Lewis, with plenty else on his mind (like getting his car back to the parc ferme in one piece and with enough fuel), didn't notice what was flashing in front of him. Superimposed, as you can see, over an image of Hamilton as a young lad still in karts is Lewis' name alongside those of the other two-time world champs: Jim Clark, Graham Hill, Emerson Fittipaldi, Alberto Ascari, Fernando Alonso and Mika Hakkinen. (Never mind those who've scored more than two titles.) Intriguingly, Hakkinen is the only other one among them to have won either of his titles under Mercedes power like Lewis did, though Fangio won two of his five titles motivated by Benz engines.

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.
