Daimler names Bernd Pischetsrieder to supervisory board

Some executives in the automotive industry stay with one company for their entire careers, while others bounce from one to the other, often leaving their indelible mark on each automaker at which they serve. Bob Lutz is certainly an example of the latter. So is Lee Iacocca, having presided over Ford and later charing the Chrysler board. Carlos Tavares was chief operating officer of Renault before being nominated as chief executive at PSA Peugeot Citroën. But as far as the Germans go, nobody's jumped from the leadership of one automaker to the next quite like Bernd Pischetsrieder - especially now that he's been named to the supervisory board of Mercedes-Benz parent company Daimler.
An engineer by training, Pischetsrieder started his career at BMW in 1973, eventually rising to the office of CEO after twenty years. There he remained until 1999, only to be dismissed after orchestrating BMW's takeover of the Rover Group (of which only the Mini brand remains in the company's portfolio, the other brands having been sold off after his dismissal).
The next year he was named chairman of Volkswagen's Seat brand, and rose to the chairmanship of the entire Volkswagen Group two years later. Despite a largely successful four-year tenure (that gave birth, incidentally, to the Bugatti Veyron), disagreements with supervisory board chairman Ferdinand Piëch saw him leave the helm at VW AG, focusing his attention on the Scania truck division. He's since been touted as a potential chief executive for Opel and for Continental, but neither potential was apparently realized.

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 intros long-wheelbase E-Class for China

Long-wheelbase sedans are a pretty hot commodity in China, and to keep up with the competition, Mercedes-Benz has introduced an extended version of the 2014 E-Class sedan at the Shanghai Motor Show. Audi, BMW, Volvo and even Cadillac offer extended versions of sedans specific to the Chinese market, and now the E-Class L, shown off in E400L guise, will give luxury sedan buyers in China yet another option.
Compared to the standard 2014 E-Class sedan, the new China-spec E-Class L has been stretched by 5.5 inches - all of which goes to the rear-seat passengers. According to an article on China View from earlier in the year, the market for chauffeur-driven cars is growing in the Asian nation, so automakers need long-wheelbase models like the E-Class L in order to fully compete. As for what powers this stretched E-Class, it's available in three models: the diesel E260L, the V6-powered E300L and the E400 Hybrid.
The redesigned E-Class and the all-new A-Class are just the first of 20 new Mercedes-Benz products that will be introduced into the Chinese auto market by 2015. Scroll down for the full press release on long-wheelbase E.
