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.

Mercedes-Benz USA confirms relocation to Atlanta

Porsche, you no longer have Atlanta to yourself. Mercedes-Benz USA has confirmed that it will be moving its corporate headquarters (shown above) from Montvale, NJ, to Georgia's most populous city. This is the second high-profile corporate relocation in the past year, as Mercedes follows in the footsteps of Toyota, which announced its relocation from California to Texas back in April (Subaru also announced a relocation, but it was just four miles away from its old offices). According to the German company, executives and their staff will relocate to an interim facility in the city's Central Perimeter until a brand-new, long-term home is completed in 2017. Around 1,000 employees will be impacted by the move, although Mercedes didn't mention if any employees would be let go as a result of the relocation. The company won't be abandoning New Jersey completely, as it will retain "several operational areas" in both Montvale and Robbinsville, NJ. As Mercedes USA CEO Steve Cannon explains, there are a number of good reasons for the company's relocation. "Atlanta is a premier city which places us closer to our ever-growing Southeast customer base, our port in Brunswick, Georgia, and to Mercedes-Benz US International, our Alabama manufacturing facility, which accounts for half of the vehicles we sell here in the US," Cannon said in a statement. "For our employees, Atlanta offers a strong quality of life, terrific schools and wonderful cultural and recreational opportunities." Mercedes-Benz USA Announces Move of Corporate Headquarters to Atlanta Several operational areas to remain in New Jersey including Parts Distribution Center and Regional Office January 06, 2015 - MONTVALE, N.J. Mercedes-Benz USA (MBUSA) today announced that it will relocate its corporate headquarters to Atlanta, Georgia, in a move designed to better serve its growing customer base and strengthen the company's position for long-term, sustainable growth. MBUSA executives and staff will relocate from its primary facility in Montvale, New Jersey, to a temporary facility in Atlanta's Central Perimeter on an interim basis. The company will construct a new, state-of-the-art headquarters expected to be completed in early 2017. MBUSA plans to begin moving employees starting in July 2015. The move, which will affect approximately 1,000 employees, will be phased to help minimize any disruption to business operations. Several operational areas will remain in both Montvale and Robbinsville, New Jersey.

The 10 car brands most expensive to maintain over 10 years

Car maintenance has got to be one of the least fun things you can do with your free time, right behind going to the dentist and filing your taxes. However, depending on the brand you buy, your time spent at the shop could be much more than you bargained for. Consumer Reports’ new study on the most- and least-expensive-to-maintain car brands found that European car companies are most likely to break your wallet with costs nearly five times that of the automakers at the other end of the spectrum. Land Rover had the highest ten-year maintenance costs, at an average of $19,250. Porsche was second worst with $14,090 in costs. 10 car brands most expensive to maintain over 10 years: Land Rover: $19,250 Porsche: $14,090 Mercedes-Benz: $10,525 Audi: $9,890 BMW: $9,500 Volvo: $9,285 Infiniti: $8,500 Acura: $7,800 Mini: $7,625 Subaru: $7,200 The Euro brands at the “top” of this list arenÂ’t all that surprising. Land Rover has consistently landed as one of the most expensive vehicle brands to maintain for years now, though Porsche is generally viewed as being one of the more solid performance brands. That could suggest that some models donÂ’t always require more repairs, but the fixes they do need are significantly more expensive. Tesla, Buick, and Toyota were the three cheapest to maintain car brands, with 10-year maintenance costs of $4,035, $4,900, and $4,900, respectively. Consumer Reports noted that these numbers could be slightly skewed due to the fact that some automakers offer free maintenance for the first few years of ownership, and all companies cover their new vehicles for at least a few years after the purchase. Routine maintenance is a great way to avoid costly repairs over time, as itÂ’s much cheaper to catch a problem before it starts causing other issues. Check your oil, rotate your tires, and avoid driving like a wild person, and youÂ’ll likely fare much better than others, even if you own one of the scarier-to-maintain brands.
