2017 Mercedes-Maybach S650 Cabriolet includes guaranteed exclusivity

For certain buyers, the only thing better than a super-luxurious cabriolet that requires enormous sums of money to buy is a a super-luxurious cabriolet that money can't buy. That's what Daimler promises with the 2017 Mercedes-Maybach S650 Cabriolet to be unveiled at the LA Auto Show. Limited to 300 units worldwide and just 75 in the US, having just three available color combinations magnifies the exclusivity. Turning the Mercedes-Benz S-Class cabrio into a droptop worthy of the Maybach family means slight revisions outside and in, and a whole lot of Maybach badges. Instead of the three lower intakes familiar from Mercedes' corporate language, there's black mesh highlighted by a shiny design element. It's not the most graceful face from dead-on, looking sort of like a chrome-lined grimace picked up from Wallace and Gromit. A Maybach emblem adorns the fenders and gleaming kickplates, the 20-inch wheels add an edge to the brand's traditional dinner-plate design. The 6.0-liter, twin-turbo V12 carries over from the donor convertible, with the same 621 horsepower and 738 pound-feet of torque hooked up to a seven-speed automatic transmission. The only three color treatments available in the US will be Zircon Red with a porcelain and black interior and a black top, Cote d'Azur Blue with a porcelain and saddle interior and a beige top, and Designo Diamond White with a porcelain and Yacht Blue interior with a dark blue top. The cabin works nautical themes lifted in part from the Mercedes-Benz Style Arrow 460-Granturismo yacht. Perforations in the leather seats evoke waterfalls. The "Flowing Lines" trim ornamenting the seats comes two different colors depending on the exterior hue; either "Piano lacquer" black with the Zircon Red or Magnolia Nut Brown with the other two options. Buyers will find profuse badging in embroidered, embossed, and inlaid varieties, as well as chrome-plated "1 of 300" lettering in several places like the cup holder and steering wheel. The few lucky customers who buy an S650 will also find a four-piece set of Maybach-badged luggage in the truck, two travel bags and two weekenders tooled up in the same leather as the interior. The key fob gets finished in Porcelain leather. A car cover comes standard, in the same color as the convertible top. A certificate signed by the mustachioed one, Daimler Chairman Dr. Dieter Zetsche, provides the corporate-badged icing on the cake.

Daimler and Geely collaborate to develop 'a highly efficient modular engine'

BERLIN — German car maker Daimler said on Tuesday it will cooperate with China's Geely to build next-generation combustion engines for use in hybrid vehicles. Efforts to share development costs come as the growth potential for combustion engines faces the twin threat of the COVID-19 crisis and stricter fuel-efficiency and emission rules. "The companies plan to develop a highly efficient modular engine," a spokesman for Daimler said, adding that it would be used in hybrid drivetrains and manufactured in Europe and China. Geely declined to comment. The modular engine will be used in cars under different marques at Geely and Daimler, a person familiar with the matter said on condition of anonymity as the companies are still in the early stages of developing the engine. News of the alliance was a surprise to Daimler's works council at its factory in Untertuerkheim, which specializes in electric and gasoline powertrain assembly. "We are speechless. There was not even a discussion about potential alternative manufacturing locations," said Michael Haeberle, the works council chief for Untertuerkheim. "We have the ability to build four-cylinder engines in Untertuerkheim, but there were no talks about it." Daimler said German factories will be retooled gradually to add electric drivetrains production. Most of the next-generation combustion engines will be made in China, business daily Handelsblatt reported. The alliance with Geely, which owns a 9.69% stake in Stuttgart-based Daimler, means that parts of Daimler's existing partnership with Renault could be pared back. A Renault source told Reuters that the Daimler-Geely project does not mean an end of cooperation between Daimler and Renault. Citing Daimler sources, Handelsblatt said the Daimler-Geely pact would save the German carmaker a "triple-digit million sum" — implying an amount above 100 million euros ($119 million) and less than 1 billion euros.

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.
