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: 2015 Canadian F1 Grand Prix is better behind the front

As of Saturday afternoon in Montreal, Canada, it was all about the number four. Lewis Hamilton put his Mercedes-AMG Petronas on pole position for the fourth time at the Circuit Gilles Villeneuve, and now his tally of pole positions matches his race number: 44. Nico Rosberg lines up beside him, which is the fourth time that particular one-two combo has occurred this season. Ferrari spent three engine development tokens to try and close the gap to Mercedes, Kimi Raikkonen making the most of it with third position on the gird. His teammate Sebastian Vettel got the worst of it, however, when the MGU-K unit failed during Q1, leaving him 160 horsepower down and out at the first hurdle. Valtteri Bottas put a revitalized Williams on the grid at fourth, ahead of a Lotus lockout of the third row with Romain Grosjean leading the way in fifth, Pastor Maldonado just beside. Nico Hulkenberg got the first Sahara Force India into seventh – the team is still waiting on the upgraded B car that should be available for Austria – ahead of Daniil Kvyat in the first Infiniti Red Bull Racing and a "pissed off" Daniel Ricciardo in the second Red Bull. Sergio Perez made it two Force Indias in the top ten, a welcome result from a team performing below expectations of late. When the lights went out, at the very front it was much ado about not that much at all. Hamilton got away clean and stabbed across the track to close the door for Rosberg, giving Raikkonen a chance to take the inside line into Turn 1 in an attempt to clear Rosberg for second place. That didn't happen, leaving the two Mercedes' to run in grid position for the entire race. It wasn't boring – Rosberg stayed close, rubber-banding the time gap to the leader from a little more than one second to just under four seconds, and Montreal is famous for race-rearranging safety cars and on-track incidents. But none of those occurred, so Hamilton crossed the line 2.285 seconds ahead of Rosberg after 70 laps to earn his fourth victory in Canada and the first-ever victory for the Brackley, UK-based Mercedes team. Valtteri Bottas drove his Williams to third position, the first podium place for the team this year and a welcome salve to heal the team's wounds from a poor showing in Monaco. That placing came courtesy of being in the right place at the right time, which was not far behind Raikkonen when the Ferrari driver spun at the hairpin on Lap 28 after his first pit stop.

Weekly Recap: Mercedes, Volkswagen spend big as import automakers invest in North America

Import automakers are on a building frenzy in North America as resurgent car sales have prompted companies to expand their manufacturing footprints to meet rising demand. That was evidenced this week when Mercedes-Benz announced plans to build a $500-million factory to produce the Sprinter commercial van, and Volkswagen confirmed a whopping $1-billion investment to expand its massive plant in Mexico. Meanwhile Jaguar Land Rover reportedly wants to build a factory in North America, but not for at least three years, and Hyundai is said to be expanding in the southern United States. The common thread in all of this expansion? Trucks, time and money. Mercedes wants to capitalize on the burgeoning work van segment in the United States and will break ground in 2016 on a 200-acre site in Charleston, SC, to build the next-generation Sprinter. The site will have a paint shop, body shop and an assembly line, and 1,300 people will be employed when production ramps up. Why do this, when Mercedes has immense van operations in Germany? It's cheaper to build in the US for the US market. Building locally allows Mercedes to avoid import taxes, forego a complex shipping process that involves partially disassembling German-built Sprinters and naturally, reduces the time it takes to deliver finished trucks to their buyers. "This plant is key to our future growth in the very dynamic North American van market," Volker Mornhinweg, head of Mercedes-Benz Vans, said in a statement. He was speaking about Mercedes and vans, but another German automotive giant, Volkswagen, had similar motives for its mammoth expansion plans in Puebla, Mexico. The added space and production capacity will allow VW to build a three-row version of the Tiguan, and provide another crossover for its US lineup that's light on SUVs. The current Tiguan has two rows. The factory will be able to churn out 500 units daily of the larger variant, and they will be sold in North and South America. It will arrive in the US in mid-2017, a spokesman told Autoblog. VW also plans to build another crossover, a midsize seven-passenger vehicle, at its growing Chattanooga, TN, site. "Localization has become key to safeguarding our competitive position on the global market, and manufacturing the Tiguan in Mexico will bring production closer to the US market," Michael Horn, CEO of Volkswagen Group of America, said in a statement.
