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.

Chicago Car2Go app reportedly hacked, some 100 cars missing

Car2Go launched in Chicago in the summer of 2018, with 400 Daimler cars rolled out on the Windy City streets soon after. But that big fleet just took a big hit: The car-sharing app has now reportedly been hacked, and some 100 cars have been stolen as a result. CBS Chicago is reporting that some of the missing cars have been used to commit crimes. It is yet unclear what the hacking has exactly enabled the perps to do, but the compromised app appears to have opened the doors and given the thieves free rein with easily stolen cars. Within Chicago, there is a 29 square mile area where the vehicles were supposed to be dropped off, but they haven't been limited from exiting that zone at any point. The Chicago Car2Go fleet started out with Smart ForTwo cars and bigger Mercedes-Benz CLA/GLA models; we can imagine the ForTwos are a touch slight for any ram raiding, but an escape car that can vanish in a crowd of other shared Smart cars seems handy for misuse. To address the matter, Car2Go froze its Chicago operations today, saying it is "neutralizing a fraud issue and working together with law enforcement." No personal or confidential user info is said to have been compromised. CBS Chicago's Brad Edwards tweeted today that 12 people have been taken into custody so far, with the story developing as we speak.

European automakers gear up for Brazilian production

Brazil is the place to be, apparently. Toyota has been investing in the South American country, as has BMW, which announced a $261 million investment in October 2012, on the heels of an Audi factory announcement in San José Chiapa. The high-end immigration is only set to continue, as Mercedes-Benz and Jaguar-Land Rover have both announced plans to set up manufacturing operations there.
Mercedes is the big news here, as its new facility will see the German manufacturer invest 170-million euros for production of its next-generation C-Class and upcoming GLA-Class. "Brazil is an important future market. With our local production we accept the challenge and take on the competition," noted Andreas Renschler, Management Board member for Production and Procurement at Mercedes-Benz Cars and Mercedes-Benz Vans. Production is expected to begin by 2016.
Jaguar-Land Rover, meanwhile, isn't so concrete in its plans. The news of its investment in South America comes from a job posting for a plant quality manager in Brazil that was picked up by the UK's AutoCar. "Portuguese language skills will be definite advantage" for interested candidates, according to the job listing. The want ad follows on the heels of remarks by Jaguar Land Rover's Dr. Ralph Speth, who said there are "very intensive discussions" with Brazil's government. Unlike Mercedes, there's no mention of which vehicles will be produced in South America, although AutoCar thinks the Freelander, sold in the US as the LR2, is a leading contender.
