Smart brand will be built in China as a Daimler-Geely joint

FRANKFURT/BEIJING — Daimler will build its next generation of Smart electric cars in China through a joint venture with Geely, as a way to increase economies of scale in a market segment that is struggling to turn a profit. China's Geely built a stake of almost 10 percent in Daimler last year, saying it wanted to forge an alliance to develop electric and self-driving cars to better compete against new challengers such as Uber and Google. Daimler said on Thursday it would build the next generation of Smart-branded city cars at a purpose-built factory in China, and planned to share its expertise in manufacturing, engineering and design with Geely. The high cost of electric car batteries has made it hard for automakers to build affordable zero-emissions vehicles, leading several of them to strike alliances with Chinese partners. Daimler's German rival BMW recently unveiled plans to build electric Minis in China, where production costs are low and demand for small electric cars is rising. Daimler and Geely did not disclose financial terms of their deal. The details of the joint venture will be finalized by the end of 2019, they said in a joint press release. Daimler currently develops and builds Smart cars with Renault at factories in France and Slovenia. The Daimler factory in Hambach, France, will be retooled to build Mercedes-Benz cars. Geely has been expanding rapidly through mergers and acquisitions since 2010, when it acquired Swedish carmaker Volvo from Ford. Last year, Daimler and Geely set up a ride-hailing joint venture in China. Daimler's Chief Executive Dieter Zetsche said last month the German carmaker was in talks to deepen its alliance with Geely after the Chinese's group's chairman Li Shufu bought a 9.69 percent stake in Daimler in 2018.

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.

Lewis Hamilton retakes F1 lead with 'miracle' victory in Germany

HOCKENHEIM, Germany – Lewis Hamilton raced from 14th to first to seize a "miracle" German Grand Prix victory in a Mercedes one-two on Sunday and retake the Formula One championship lead from Ferrari's Sebastian Vettel, who crashed. Vettel, now 17 points behind the Briton after starting eight ahead, led his home race from pole position until rain caused chaos in the closing laps, with the German sliding off and into the barriers. Hamilton, the reigning world champion, took the chequered flag for a record-equalling fourth German Grand Prix win, ahead of his Finnish team mate Valtteri Bottas and Ferrari's Kimi Raikkonen. "I've never had a race like this," said the four-times champion, who was summoned to stewards after the race for a pitlane infringement but escaped with a reprimand and the victory intact. "Today I feel like I drove the best that I can remember driving. I didn't make any mistakes." It was the 66th win of his F1 career, and Mercedes' 80th, and minutes after the finish, the skies opened with an array of thunder and lightning and a torrential downpour that would have stopped any race. "Miracles do happen, mate," Hamilton's race engineer Pete Bonnington told him over the radio after a slow-burner that turned into one of the great comebacks of the Briton's already stellar career. Hamilton, who threw himself across the pitlane wall into the arms of his mechanics and also got a bear-hug from delighted Mercedes-Benz boss Dieter Zetsche, seemed about as stunned as anyone. "I really feel that the rain has come down and just washed away any negativity and its a glorious day," Hamilton said, his voice wobbling. "It couldn't have been a better day for me and one that I will always remember." FERRARI NIGHTMARE Beaten by Vettel in his home British Grand Prix at Silverstone two weeks ago, where he went from pole to the back of the field and up to second, he had turned the tables completely. "Love conquers all," declared Hamilton, who had reacted defiantly on Instagram to the booing and hostility from a partisan crowd after his car broke down in Saturday's qualifying. "It's obviously very, very difficult from that position and highly unlikely but you've always got to believe," added the four-times champion, who said a long prayer before the race started. "I really manifested my dream today." For Vettel, it was simply a nightmare – the chance to make big gains slipping through his hands in an instant. He now has 171 points to Hamilton's 188.
