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.

NHTSA, IIHS, and 20 automakers to make auto braking standard by 2022

The National Highway Traffic Safety Administration, the Insurance Institute for Highway Safety and virtually every automaker in the US domestic market have announced a pact to make automatic emergency braking standard by 2022. Here's the full rundown of companies involved: BMW, Fiat Chrysler Automobiles, Ford, General Motors, Honda, Hyundai, Jaguar Land Rover, Kia, Mazda, Mercedes-Benz, Mitsubishi, Nissan, Subaru, Tesla, Toyota, Volkswagen, and Volvo (not to mention the brands that fall under each automaker's respective umbrella). Like we reported yesterday, AEB will be as ubiquitous in the future as traction and stability control are today. But the thing to note here is that this is not a governmental mandate. It's truly an agreement between automakers and the government, a fact that NHTSA claims will lead to widespread adoption three years sooner than a formal rule. That fact in itself should prevent up to 28,000 crashes and 12,000 injuries. The agreement will come into effect in two waves. For the majority of vehicles on the road – those with gross vehicle weights below 8,500 pounds – AEB will need to be standard equipment by September 1, 2022. Vehicles between 8,501 and 10,000 pounds will have an extra three years to offer AEB. "It's an exciting time for vehicle safety. By proactively making emergency braking systems standard equipment on their vehicles, these 20 automakers will help prevent thousands of crashes and save lives," said Secretary of Transportation Anthony Foxx said in an official statement. "It's a win for safety and a win for consumers." Read on for the official press release from NHTSA.

Automakers making the commitment are Audi, BMW, FCA US LLC, Ford, General Motors, Honda, Hyundai, Jaguar Land Rover, Kia, Maserati, Mazda, Mercedes-Benz, Mitsubishi Motors, Nissan, Porsche, Subaru, Tesla Motors Inc., Toyota, Volkswagen and Volvo Car USA.

Mercedes-Maybach GLS could become the most expensive car made in America

Mercedes-Benz International, the German automaker's manufacturing facility near Vance and Tuscaloosa, Ala., already builds the GLS SUV. Autonews reports that the coming ultra-luxe version of the large crossover, the Mercedes-Maybach GLS, will be built in Alabama as well for global markets. The most recent timelines mark the reveal in production or near-production form in China, with sales to commence next year. The next-gen series-production GLS goes on sale later this year. The gilded sub-brand previewed a wild concept last year in China called the Vision Mercedes-Maybach Ultimate Luxury, which blended the tall profile of an SUV with the truck of a sedan on donk wheels. Based on spy shots, none of that fancy will make it to production. Both the Maybach and AMG versions of the GLS ride on fat rubber but look thoroughly traditional. The treasure will be inside. Autonews said China accounts for roughly 75 percent of Maybach S-Class sedan sales. That suggests the GLS in baroque trim will emphasize chauffeured luxury touches like rear captain's chairs and lots of rear legroom. Pricing estimates figure $200,000 to get in the door. That would put the SUV right in line with the Lamborghini Urus and a couple stacks of Benjamins above the Bentley Bentayga, with much the same likely audience. One analyst said, "The ultra-high-net-worth kids want something different, and these ultraluxury SUVs certainly fit that," while another opined on its "appeal to the Kardashians and hip-hoppers, if they want something slightly different to the G-Wagen." A $200K MSRP would also comfortably make the Maybach GLS the most expensive new car built in America, taking the title from the Acura NSX. With a great price comes great power, said to be a twin-turbo V8 with more than 560 horsepower. The coming GLS 450 will make do with somewhere around 360 hp. The Alabama plant, which also builds the GLE, GLE Coupe, and C-Class, is also undergoing a $1 billion upgrade to more than double the size of the facility, making lines for battery production and EQ-series vehicle assembly,
