Geely plans to launch hundreds of satellites to guide autonomous cars

BEIJING — China's Zhejiang Geely Holding Group said on Tuesday it was investing 2.27 billion yuan ($326 million) in a new satellite manufacturing plant, where it plans to build low-orbit satellites to provide more accurate data for self-driving cars. Geely, one of China's most internationally-known companies due to its investments in Daimler, Volvo and Proton, is building the facilities in Taizhou, where it has car plants. It aims to produce 500 satellites a year by around 2025, with around 300 highly-skilled staff, it said in a statement. Geely's technology development arm, Geely Technology Group, launched Geespace to research, launch, and operate low-orbit satellites in 2018. Geespace will begin the launch of its commercial low-orbit satellite network by the end of this year, Geely said. Geely said low-orbit satellites would offer high speed internet connectivity, precise navigation, and cloud computing capabilities to cars with autonomous driving technology. Geely, which sold 2.18 million cars last year, is among global automakers from Tesla to Toyota to pursue autonomous driving technologies. It is building low-orbit satellites to meet demand for high-speed connectivity capabilities that can deliver fast software updates. From around 2025, Geely's cars will have more functions to connect to the satellites. Related Video: This content is hosted by a third party. To view it, please update your privacy preferences.

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.

2016 Mercedes-Benz C450 AMG Sport is not too hot, not too cold

Mercedes-Benz is moving to a new system for performance models, launching its AMG Sport line that will slot above the standard cars, but below the full-fledged Mercedes-AMG offerings. The perfect example of how this all looks can be seen with the C-Class – we've already driven (and enjoyed) the standard C300 and C400 offerings, and we're absolutely geeked to test the Mercedes-AMG C63. Slotting in the middle, though, is this new C450 AMG Sport, which makes its debut at the Detroit Auto Show this week. Power comes from the twin-turbocharged 3.0-liter V6 found in the C400, but output is increased to 362 horsepower and 384 pound-feet of torque – up from 329 and 354, respectively. That's all shuffled through the company's 7G-Tronic seven-speed automatic transmission, and sent to the road via 4Matic all-wheel drive. Hitting 60 miles per hour is said to take just 4.9 seconds, en route to a 155-mph top end. There's an AMG adaptive sport suspension with adjustable dampers (from the C63), and the interior and exterior aesthetics have been pumped up for a more sporting appearance. It all seems like a good fit, and we think it'll slot nicely in the middle of the already good C-Class range. Check out our fresh batch of lives images of the C450 above.
