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.

Geely chairman is now the single biggest investor in Daimler

Li Shufu, the chairman and main owner of Chinese carmaker Geely, has built a stake of 9.69 percent in Daimler AG, the German carmaker said in a regulatory filing on Friday. The stake, worth nearly $9 billion at the current valuation for Daimler shares, makes Li the biggest single shareholder in the maker of Mercedes-Benz cars, trucks and vans headquartered in the German city of Stuttgart. A Daimler spokesman called the stake purchase a private investment by Li. "We are delighted, with Li Shufu, to have won over another long-term investor who is convinced of Daimler's innovative prowess, strategy and future potential," the spokesman said in response to a request for comment. "Daimler knows and respects Li Shufu as a Chinese entrepreneur of particular competence and forward thinking." Li's stake purchase makes him the top shareholder in Daimler ahead of the Kuwait Investment Authority, which owned 6.8 percent as of Sept. 30, according to Thomson Reuters data. Earlier this month, the German newspaper Bild am Sonntag reported that the Chinese industry giant was seeking to become Daimler's biggest shareholder, likely exceeding the 6.8-percent stake of the Kuwait Investment Authority. The paper said Daimler had reportedly turned down Geely's $4.5 billion offer for a 5-percent stake via a discounted share placement, saying that Geely could buy shares in the open market. Institutional investors currently own 70.7 percent of Daimler, and the company already has strong ties to Chinese automakers BAIC and BYD. Bild am Sonntag said the move was intended as a strategic alliance against Apple, Google and Amazon on autonomous and connected cars. And Reuters reported that Daimler wants to have bespoke "robo taxis" on the road quicker than Google's Waymo, and views Geely as a strong partner for that. Geely conversely is interested in Daimler's electric car battery technology, and sources quoted by the German paper say there are plans to establish joint electric car manufacturing in Wuhan, China, to meet China's smog-reducing quotas. Geely is developing the Lynk & Co. brand of electric and hybrid cars. Geely owns Volvo, which has enjoyed a renaissance under the arrangement, as well as the maker of London's black cabs. In December, it bought a stake in AB Volvo, the maker of Volvo trucks.

2015 Mercedes C-Class owners reporting bleeding seats [UPDATE]

UPDATE: Daimler AG became aware that, in a small number of individual cases, it is possible for temporary spots and/or shiny patches to form on the man-made leather surfaces of the 2015 C-Class in sub-freezing temperatures. No accidents or injuries have been reported, and we have no reason to believe that there are any hazards to customers. Replacement parts are expected to start shipping to dealers by next week. Owners of the 2015 Mercedes-Benz C-Class are learning the hard way that you don't necessarily want to buy a new vehicle in its first model year. Besides reports of poorly fitting taillights and faulty infotainment touchpads, a number of reports are popping up on the forums of MBWorld.org claiming that the compact luxury sedan's seats are, for lack of a better term, bleeding. Owners of US-built, 2015 C-Classes fitted with MB Tex vinyl interiors are reporting a white, oily, shiny residue discoloring their seats that shows up, often after cold cars are quickly heated. It's important to note that this residue is not necessarily staining the seats permanently – warm, soapy water is often all that's needed to restore the original finish. In other cases, the residue disappears of its own accord, only to reappear in an entirely different pattern. That doesn't make things any more acceptable to owners, many of whom have reached out to Mercedes with complaints. It's not clear how many vehicles are affected, but there are a sizable number of forum threads on the issue on MBWorld alone, and the problem is prevalent enough that Mercedes has issued a technical service bulletin to its dealers. According to the forum postings, the TSB instructs service technicians to replace the headrest and seat cover (except for the front, passenger-side seat bottom because of "factory calibration issues") in affected customer vehicles. New C-Class models in dealer inventories, meanwhile, are to get the soapy water treatment if they're showing signs of the residue. Neither one of those moves seems to represent a long-term fix, though. Black MB Tex seats – both the standard and sport variety – seem to be particularly susceptible to the residue, although we stumbled across at least one image of what looks like Silk Beige MB Tex with speckles of residue.
