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.

Brabus bringing 900-horsepower Mercedes S65 to Geneva

The S-Class may be the ultimate Mercedes, but what's the ultimate S-Class? Is it the S550? Maybe in some markets, but that's just the starting point in North America. The S600? Getting closer. The Maybach? Sure, if the last word in luxury is what you're after. But if it's performance you crave, then you'll want an AMG version like the S63. But even that's not the flagship. No, in terms of outright power, it all comes down to the S65. It's got a 6.0-liter twin-turbo V12 churning out 621 horsepower and 738 pound-feet of torque, for crying out loud. But Brabus thinks it's still not enough. That's why (alongside the 850-hp S63 coupe) it's bringing a version it calls the Rocket 900 to the Geneva Motor Show this week. To turn the S65 AMG into the Rocket 900, Brabus has bored out the cylinders to total 6.3 liters and fitted larger turbochargers, a new exhaust system, intake module and much, much more. The result is an output increased to 887 bhp and 1,106 lb-ft of torque. Brabus has upgraded the limited slip differential to handle the extra muscle, helping it rocket to 62 in just 3.7 seconds, on to 124 in 9.1 and up to a top speed of 217 Autobahn-crunching miles per hour. The famed Benz tuner has also fitted a carbon-fiber aero kit to keep it from flying away (however unlikely considering the vehicle's approximately 5,000-lb curb weight), along with 21- or 22-inch wheels, a retuned air suspension that drops the ride height over half an inch closer to the road and – we can only hope since the release makes no such mention – upgraded brakes as well to keep it all in check. Brabus also offers a full range of interior enhancements as well, but don't expect any of this to come cheap. As it is, the S65 starts at $222,000, but a turn-key Brabus Rocket 900 goes for 347,719 euros – or about $390k at today's rates.
