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.

2014 Mercedes-Benz CLA order guide leaked

The dealer order guide for the 2014 Mercedes-Benz CLA has made its way online courtesy of the crew at CLAForums.com, and not only does it shed light on the ways buyers will be able to configure the entry-level sedan, it talks specific option pricing. Shoppers will be able to select between the CLA250 and CLA250 4Matic, and the option sheet should offer a number of packages to suit buyer tastes, including a sport package with tweaked fascias and unique wheels. Bi-xenon headlamps and 18-inch alloys may also be had as well as a panoramic sunroof and a collision avoidance system. The CLA will be available with a number of active safety systems on board, including lane departure warning, adaptive cruise control, park assist and blind spot assist, to name a few.
The new sedan comes in 10 colors, including a very dashing purple Mecedes-Benz calls Northern Lights Violet, and there are a total of four interior trim finishes. The automaker hasn't released final pricing of all models just as of yet - we do know from Mercedes' Kate Upton Super Bowl ad that the car will start at $29,900 - but you can check out individual option and package pricing in the gallery. You can also find more information over at CLAForums.com.

Mercedes-Maybach spied inside and out sporting the huge S-Class screen

A new Mercedes-Benz S-Class is well on its way, and that means a new Mercedes-Maybach is following right behind it. We were introduced to the new Mercedes-Maybach strategy over five years ago. At the end of 2019, Mercedes added to the small collection with the GLS 600, bringing an SUV into the Maybach fold. These spy shots mark our first good look inside and outside the next-gen Mercedes-Maybach sedan. We’ll point out the massive screen first. Photos of this huge slab of screen have largely shown it turned off. Now, we get a solid look at the display all lit up and running MercedesÂ’ next iteration of MBUX. The icons and UX look a whole lot like MercedesÂ’ current infotainment system design, just blown up to a much larger size. Mercedes is surely going to hit us with some new out-there features we didnÂ’t know we wanted and may not even use, but thatÂ’s the way it goes with excessive luxury. The gauge cluster is pretty standard for new Mercedes with a flat digital screen. An “EQ” emblem displayed in the cluster also indicates that Mercedes plans to implement its EQ Boost mild-hybrid tech with the turbocharged engine(s) offered in this new generation. The current car comes in S560 (V8) and S600 (V12) variations. We don't know what MercedesÂ’ powertrain plans are for the time being, but the GLS 600 uses 48-volt technology with its 4.0-liter twin-turbo V8 and makes 550 horsepower and 538 pound-feet of torque. Ideally, the smooth and silky V12 sticks around in the top-shelf S-Class as well. As for the design, itÂ’s exactly what one might expect from a Mercedes-Maybach. The wheelbase is stretched compared to the regular S-Class weÂ’ve spied before, and it has the signature slatted grille. Pop-out door handles appear to be carried over from the new S-Class, too. We expect the new S-Class isnÂ’t far from a reveal. ThereÂ’s a chance it still breaks cover this year, even as most automakers face delays from the coronavirus. Once itÂ’s out, the Mercedes-Maybach is likely to follow soon after. Related video:
