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.

Leopard walks in, shuts down a Mercedes-Benz plant

In recent months the auto industry has seen plant closures due to a host of reasons — parts shortages, recalls, natural disasters, and even a once-in-a-lifetime pandemic. Now it can add to that list the threat of an invading leopard. A Mercedes-Benz factory in Pune, India, was forced to halt production for a few hours when a wayward jungle cat wandered into the facility, When the 3-year-old male leopard was spotted inside the manufacturing unit of the factory, it caused a panic among workers, according to a release by rescue organization Wildlife SOS discovered by The Drive. The site was shut down for about six hours as a Wildlife SOS rapid response team from the Manikdoh Leopard Rescue Centre and the State Forest Department safely removed the curious cat.

The team's veterinary officers Dr. Nikhil Bangar and Dr. Shubham Patil carried out the rescue operation, tranquilizing the feline and loading it into a wildlife carrier. The rescue took about four hours, and Wildlife SOS reports that neither the creature nor any workers sustained injuries. The leopard was released back into the wild.  No one is quite sure how it got onto the factory grounds, but Wildlife SOS says that the forests in the surrounding region have one of the highest densities of leopards in the world. It's also suffering from rapid deforestation. That encroachment by humans has led to a decrease in the leopard's natural prey as well, so wildlife experts think it may have been looking for food.  The Mercedes plant builds the Maybach S 560, S-Class, E-Class Long Wheelbase, C-Class, CLA, GLA, GLE and GLS for the Indian market.  We have a different theory. We believe that the cat was seeking to set the record straight with Mercedes. When the S 65 AMG debuted, Mercedes claimed it featured the world's first Road Surface Scan technology to detect pavement undulations and adjust suspension damping accordingly. The only problem with that claim: Nissan had the technology some 30 years earlier in several mid-80s models, including the Maxima and Japan's version of the Infiniti M30, which was called — you guessed it — the Leopard.
