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.

Some intriguing showstoppers from Auto China 2024

“Electric” may be the most appropriate word to describe the atmosphere at the recent Beijing motor show, now considered to be one of the worldÂ’s largest automobile exhibitions. ChinaÂ’s vision of the electric mobility future is on full display during the ten-day event, which ends this weekend. Organizers estimated that 117 new global and China-domestic models would debut in Beijing. In fact, about 30 foreign brands had stands, a turnout that hasnÂ’t been seen at auto shows since before the pandemic. The South Koreans and the Japanese came, and from Germany, representatives making the case for their brands included CEO Oliver Blume of Volkswagen Group, Oliver Zipse of BMW Group and Ola Kallenius of Mercedes-Benz Group. A few of the models would be powered by gasoline—by ICE, or internal combustion engines—but the vibe was clear: electrics are it. According to to show officials, Beijing hosted a total of 278 electric and plug-in hybrid models on display. After digesting most of the reveals unveiled during the show, weÂ’ve parsed a list to a select few of the more interesting models. Here it is, in no particular order: BYD Ocean-M concept BYD has launched off-roaders, SUVs and sedans in its global assault on the car market — and added a hot hatch concept at Auto China. The Ocean-M (above) is a Volkswagen Golf-sized five-door hatchback, meaning itÂ’s likely that BYD will pitch it as a rival for the Volkswagen ID.3 GTX. The show car has sporty design, rises sharply towards the rear window, and sharp surfacing at the front and along the flanks. The show car has a huge rear wing, aero diffuser and side blades.   Denza Z9GT BYDÂ’s luxury brand, Denza, a joint venture between BYD and Mercedes-Benz, showed the Z9 GT, a massive wagon carrying three electric motors putting out a stunning 952 horsepower. The EV weighs an extraordinary 6,338 pounds, almost 440 pounds more than a Rolls-Royce Cullinan. BYD's design boss is a German -- Wolfgang Egger, who previously worked for Alfa Romeo and Audi. Lamborghini Urus SE The Volkswagen subsidiary brought a bit of Italian sex appeal to Beijing in the form of “super” luxury SUV that received its first public premiere in China. The plug-in hybrid Uris SE SUV gets nearly 800 horsepower as well as a series of visual and technology updates inside and out.

Mercedes-Maybach GLS Edition 100 layers on the opulence

The Mercedes-Maybach S-Class Edition 100 was revealed yesterday, but it wasn’t the only new Maybach product to come out. No, in addition to the S-Class, Mercedes took the wraps off the Mercedes-Maybach GLS Edition 100. We didnÂ’t have the details for the SUV version right away, but we have them now. None of those details are all that surprising, though. The GLS Edition 100 is built to celebrate the same Maybach centennial milestone as the S-Class, and its appearance is essentially a copycat of the sedan. The one key difference versus the sedan is the number of cylinders under the hood. Mercedes puts its V12 in the S-Class, while the GLS soldiers on with the V8. Let the tears made of money flow for the lack of the additional four cylinders. At least everything else is largely equivalent. The GLS Edition 100 gets painted in the same Designo Crystal White and Silver Grey Pearl two-tone paint scheme. YouÂ’ll find the “Edition 100” Maybach logo on the D-pillar of the GLS. Plus, the logo makes another appearance on the stunning forged grey wheels. The interior of the GLS Edition 100 is also similar to the S-Class, in that itÂ’s finished with a special leather design that is also two-tone in nature with Crystal White and Silver Grey Pearl hides. Everybody who buys one of these Edition 100 cars gets a unique branded car cover and a special case meant to store keys and the carÂ’s paperwork. Pricing isnÂ’t detailed, but Mercedes says Edition 100 cars will be at dealers at the start of 2022 — orders will be taken in the fourth quarter of this year. Related video:
