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 Formula 1 Chinese Grand Prix recap: another wild show on and off track

Normally we use this space to provide a lengthy recap of the weekend's Formula 1 race, but we're going to try something different since most folks reading this know what happened at the Shanghai International Circuit on Sunday. Instead, we'll alight on what we saw as the big issues in and around the race. Let us know what you think in Comments. Proper qualifying is back. Thank goodness. It only took a month of embarrassment to fix it. And so is passing! For the third race in a row, big performance improvements at the ten teams behind Mercedes-AMG Petronas and a wider tire selection at this race graced us with opening stints filled with dicing cars. Seeing the McLarens on screen doesn't make us cringe. Manor doesn't only make the global feed when it's being lapped. We've been complaining about parade races for so long that we forgot excitement was possible without rain or wholesale regulation changes. Yes, Mercedes is still the king of the jungle, but there are some other proper midfield beasts on the hunt, too. Malfunctions up and down the grid did help the show in Shanghai, like Lewis Hamilton suffering perpetual troubles, Nico Hulkenberg's runaway front wheel which red-flagged Q2, and Sebastian Vettel's and Kimi Raikkonen's flubbed hot laps in Q3 that let Daniel Ricciardo slip by into second on the grid. Come race day things went all Grand Theft Auto at Turn 1 on the opening lap, sending some of the best cars to the pits. Then came Ricciardo's puncture while leading, then came the Safety Car – all by Lap 5. Nico Rosberg got 38 seconds of airtime on the way to victory – at the start and the finish, and that happened to be his margin of victory, too – otherwise he was a ghost. Everyone else was struggling and juggling. Rosberg's win at the Bahrain Grand Prix put the German at five consecutive victories going back to last year's Mexican Grand Prix. The history books show that any driver who's won five straight contests has gone on to win the championship. With his triumph in China, the German has won the season's first three races, the history books again show that the other nine drivers who've pulled that off have gone on to win the championship. Rosberg, 36 points ahead of his teammate in the standings, is having none of it. He said of the other victors, "But they didn't have Lewis Hamilton as their team-mate." Perhaps Mercedes was right not to make an engine deal with Red Bull last season.

European automakers gear up for Brazilian production

Brazil is the place to be, apparently. Toyota has been investing in the South American country, as has BMW, which announced a $261 million investment in October 2012, on the heels of an Audi factory announcement in San José Chiapa. The high-end immigration is only set to continue, as Mercedes-Benz and Jaguar-Land Rover have both announced plans to set up manufacturing operations there.
Mercedes is the big news here, as its new facility will see the German manufacturer invest 170-million euros for production of its next-generation C-Class and upcoming GLA-Class. "Brazil is an important future market. With our local production we accept the challenge and take on the competition," noted Andreas Renschler, Management Board member for Production and Procurement at Mercedes-Benz Cars and Mercedes-Benz Vans. Production is expected to begin by 2016.
Jaguar-Land Rover, meanwhile, isn't so concrete in its plans. The news of its investment in South America comes from a job posting for a plant quality manager in Brazil that was picked up by the UK's AutoCar. "Portuguese language skills will be definite advantage" for interested candidates, according to the job listing. The want ad follows on the heels of remarks by Jaguar Land Rover's Dr. Ralph Speth, who said there are "very intensive discussions" with Brazil's government. Unlike Mercedes, there's no mention of which vehicles will be produced in South America, although AutoCar thinks the Freelander, sold in the US as the LR2, is a leading contender.
