German companies team up with telecom to spur development of talking cars

With connectivity and communications becoming an ever larger part of the automotive world, German automakers Audi, BMW, and Daimler formed the 5G Automotive Association with Intel, Nokia, Ericsson, Qualcomm, and Huawei. The goal is to develop new technologies to take advantage of LTE and 5G advancements, create standards, and overcome regulatory issues. If they succeed, it will be easier for them companies to develop and implement new technologies. For instance, we could see smarter traffic management, and maybe platooning, advance further in the autonomous sector. By acting as a group, they will also be able to address regulatory issues more easily. All of these companies are capable of developing advanced vehicle communication systems on their own. Audi, in fact, has been pursuing vehicle-to-infrastructure (V2I) technology and launched a stoplight timer in models in some cities. Still, the alliance offers the potential to save time and develop new ideas.

2016 Mercedes-Benz Metris First Drive

We're sitting 8,700 feet above sea level in the idyllic old mining town of Dunton Hot Springs, nestled deep in the Rocky Mountains of Colorado. We've come to drive the newest and cheapest Mercedes-Benz, a midsize work van called the Metris. As the day begins, Mercedes van boss Bernhard Glaser states the obvious, "We're setting up camp in the US." It's a good line, perhaps a little too fitting given our surroundings, but it's accurate. Though the US commercial van market is dominated by Ford and General Motors, Mercedes has staked out a competitive position and is digging for more. The tall, capable Sprinter relaunched with a Mercedes badge in the United States in 2010 and has grown into a $1-billion enterprise in America. Now comes Phase 2, dubbed "Mission Metris," starring a tweener van that's smaller than the towering Sprinter yet larger the Ford Transit Connect and Nissan NV200. The 2016 Metris enters a crowded and evolving segment that also includes the Ram ProMaster City and GM's super-old Chevy Express and GMC Savana. Mercedes will sell the Metris in cargo and passenger forms, meaning it will be outfitted for a range of roles, including taxi and limousine companies, delivery duties, service, and maintenance. Yes, your cable guy might show up in a Mercedes. That's part of the plan, actually. Though the Metris was engineered to be a pack-mule of a van, if the shine of the star on its grille helps attract new buyers – like a chain of upscale hotels that needs a fleet of shuttles – all the better. Our short test drive begins outside the small canyon town of Dolores, CO, as we haul four people and some luggage to the airport in a pre-production Metris. Normally test programs staged by automakers are a little contrived – many feature an off-road course or track time for even the most mundane vehicles – but our stint behind the wheel of the Metris is almost exactly how the van could be used in real life. We make our way along Colorado's winding highways, cruising around 60 miles per hour for much of it. The Metris offers an excellent view of the road and the snow-capped mountains that rise in the distance. It's an easy van to drive. We don't feel like we're piloting a U-Haul or something else cumbersome. Mercedes is billing this as the 'right-sized' option, and our initial impressions support that sentiment as we navigate the curves flanked by steep drop-offs.

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.
